The first CVE, addressed in [Security Note 3123396](<https://launchpad.support.sap.com/>), received the tip-top risk score \u2013 a 10 out of 10. The other two CVEs received scores of 8.1 and 7.5, respectively.\n\nThe issues are severe enough that the U.S. Cybersecurity and Infrastructure Security Agency (CISA) issued a [security advisory](<https://www.cisa.gov/uscert/ncas/current-activity/2022/02/08/critical-vulnerabilities-affecting-sap-applications-employing>) about them this week. And, in a [blog post](<https://blogs.sap.com/2022/02/08/sap-partners-with-onapsis-to-identify-and-patch-cybersecurity-vulnerabilities/>), SAP director of security response Vic Chung confirmed the severity of Onapsis\u2019 findings. He said that if they aren\u2019t remediated, the bugs \u2013 aka \u201cICMAD\u201d \u2013 \u201cwill enable attackers to execute serious malicious activity on SAP users, business information and processes.\u201d\n\nSpecifically, successful exploitation could lead to this frightening laundry list of cybersecurity hazards:\n\n * Hijack of user identities, theft of all user credentials and personal information\n * Exfiltration of sensitive or confidential corporate information\n * Fraudulent transactions and financial harm\n * Change of banking details in a financial system of record\n * Denial-of-service attack that disrupts critical systems for the business\n\nOnapsis, which specializes in security for SAP, Oracle, Salesforce and other software-as-a-service (SaaS) platforms, joined SAP in coordinating the release of[ a Threat Report](<https://onapsis.com/icmad-sap-cybersecurity-vulnerabilities?utm_campaign=2022-Q1-global-ICM-campaign-page&utm_medium=website&utm_source=third-party&utm_content=CISA-alert>) describing the critical vulnerabilities on Tuesday.\n\nThe firm estimated that there were tens of thousands \u2013 approximately 40,000 \u2013 SAP customers running more than 10,000 potentially affected, internet-exposed SAP applications at the time of disclosure.\n\nSAP and Onapsis urged customers to apply both Security Note 3123396 and [3123427](<https://t.nylas.com/t1/116/4a3z713b1kum7z18ruaq7siqk/13/51ec755ca6f695096592b0335df2b6ec4ba279684d0ae63b9df0739442312162>) without delay.

That goes for internal-facing apps as well as internet-facing ones, he said, given that ICM is at the core of practically all SAP-based web applications, and that includes apps that are internal-only.\n\n\u201cEven if the applications are internal-only, there\u2019s still risk when combined with other threats, including disgruntled employees and compromised network devices,\u201d he told Threatpost via email on Thursday. \u201cThis is exactly the vulnerability that threat actors like ransomware operators and state operatives are looking for.\u201d\n\nSAP servers are \u201cextremely rich targets,\u201d noted Aaron Turner, vice president of software-as-a-service (SaaS) posture at AI cybersecurity company Vectra. They have \u201csignificant\u201d access to material business processes and, generally, have multiple privileged credentials stored and used on those servers, he said via email.\n\n\u201cWith the Onapsis research, they have uncovered an exploit path that allows attackers to gain access to those privileged credentials to move laterally within the on-premises network, and also pivot into the cloud as most SAP customers have federated their legacy SAP workloads with cloud-based ones,\u201d Turner explained.\n\nHe compared the potential for exploitation to that presented by [Hafnium](<https://threatpost.com/hades-ransomware-connections-hafnium/165069/>): an advanced persistent threat (APT) believed to be linked to the Chinese government that Microsoft said has carried out zero-day attacks on Microsoft Exchange servers using the group of vulnerabilities known as [ProxyLogon](<https://threatpost.com/microsoft-exchange-servers-proxylogon-patching/165001/>).\n\n\u201cJust as Hafnium allowed attackers to pivot from on-prem Exchange to M365, this SAP attack path could allow the same,\u201d Turner suggested. \u201cThe SAP security updates will be critical ones to install, not just to protect those on-premises SAP servers but also any systems, on-prem or cloud, that may share credentials or trust relationships with those servers.\u201d\n\nMike Parkin, engineer at enterprise cyber-risk remediation SaaS provider Vulcan Cyber, told Threatpost that regardless of the current lack of reports of ICMAD exploits, \u201cthe potential risk is high.\u201d\n\nAll the more reason for organizations that rely on the affected components to deploy the patches and other relevant mitigations \u201cas soon as is practical,\u201d he advised.\n\n_021022 12:24 UPDATE: Added input from Casey Bisson, Aaron Turner and Mike Parkin._\n\n_**Check out our free **_[_**upcoming live and on-demand online town halls**_](<https://threatpost.com/category/webinars/>)_** \u2013 unique, dynamic discussions with cybersecurity experts and the Threatpost community.**_\n", "cvss3": {"exploitabilityScore": 3.9, "cvssV3": {"baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "CHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "baseScore": 10.0, "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H", "version": "3.1", "userInteraction": "NONE"}, "impactScore": 6.0}, "published": "2022-02-10T16:39:04", "type": "threatpost", "title": "SAP Patches Severe \u2018ICMAD\u2019 Bugs", "bulletinFamily": "info", "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, "acInsufInfo": false, "obtainUserPrivilege": false}, "cvelist": ["CVE-2021-44228", "CVE-2022-22532", "CVE-2022-22533", "CVE-2022-22536"], "modified": "2022-02-10T16:39:04", "id": "THREATPOST:DD0FE8D3D9D205FA5CCA65C3EBDD62D2", "href": "https://threatpost.com/sap-patches-severe-icmad-bugs/178344/", "cvss": {"score": 10.0, "vector": "AV:N/AC:L/Au:N/C:C/I:C/A:C"}}, {"lastseen": "2022-02-10T17:51:24", "description": "There\u2019s a trio of critical vulnerabilities, fixed on Tuesday, in SAP business applications that use the ubiquitous Internet Communication Manager (ICM): the component that gives SAP products the HTTPS web server they need to connect to the internet or talk to each other.\n\nThe vulnerabilities, discovered by Onapsis Research Labs, are tracked as CVE-2022-22536, CVE-2022-22532 and CVE-2022-22533.

For those in the audience unfamiliar with our shtick, [every month](<https://www.trellix.com/en-us/about/newsroom/stories/threat-labs/the-bug-report-january-2022.html>) we compile a shortlist of the top vulnerabilities of the month, so that they might whittle away at your last few hours of peaceful sleep. \n\nIt\u2019s a testament to the excitement of the last few months that February came as something of a reprieve for many of us who follow the ebbs and flows of the vulnerability landscape. But as we all slow down and catch our breath, someone, somewhere is having their personal information leaked, their intellectual property held by ransomware, or their privacy otherwise abused by a 0-day...and you're probably here for the grisly details. So, we at Trellix dutifully present to you our four high-impact vulns released during the month of February:\n\n * CVE-2022-22620: Apple WebKit\n * CVE-2022-0609: Google Chrome\n * CVE-2022-24086: Magento/ Adobe Commerce \n * CVE-2022-22536: SAP Internet Communications Manager\n \n\n\n## CVE-2022-22620: Apple finally gave something away for free!\n\n### What is it?\n\nWebKit is Apple\u2019s browser engine. If you are browsing the internet using an Apple product, I\u2019d bet with next month\u2019s rent money that WebKit is churning behind the scenes. Versions of WebKit prior to iOS 15.3.1 contain a use-after-free vulnerability (which occurs due to shoddy memory management) that can allow full remote code execution on a victim\u2019s device. The avenue of attack most likely to be used by attackers is a malicious URL (remember phishing from those pesky compliance trainings?) or via embedding the payload in a cross-site scripting attack on a vulnerable webpage. In the same terse fashion we curious souls have come to expect, Apple has withheld further detail on this vulnerability and the nature of the exploit. \n\n### Who cares?\n\nI care. I have an iPhone. And so do [6 million](<https://securityboulevard.com/2022/02/apples-zero-day-0-click-critical-vulnerability-cve-2022-22620/>) of you on Twitter, apparently, who likely rely on Apple products for either professional or personal tasks. To make this threat even less abstract for us Apple used-to-be-elite-now-commoners, there have been [reports](<https://twitter.com/Laughing_Mantis/status/1494394742821425164>) of CVE-2022-22620 being exploited in conjunction with privilege escalation to gain access to users\u2019 cameras and microphones.\n\n### What can I do?\n\nUpdate. Gotta update, always. To make sure your iPhone is running the patched version of iOS, go to Settings &gt; General &gt; About. If the \u201cSoftware Version\u201d shows something older than 15.3.1, that device is vulnerable, and it would be best to update immediately.\n\n### The Gold Standard\n\nAt this point, patching via software update is your best option. If you would like to have security and other updates installed automatically overnight upon release by Apple, this can be configured on all relevant devices to ensure you are free of exposure as quickly as possible.\n\n \n\n\n## CVE-2022-0609: Should you switch to Firefox?\n\n### What is it?\n\nAppearing like roaches, use-after-free browser bugs travel in groups. This one was discovered in-house at Google, by the Threat Analysis Group, inside of Chrome\u2019s animation component. Although some interaction from the user is required to carry out a successful exploit, this vulnerability can be leveraged to send and execute commands on a victim\u2019s machine over a local network.\n\n### Who cares?\n\nThe hundreds of millions of Chrome users (backed by Chrome\u2019s nearly two-thirds market share among today\u2019s browsers) may want to pay it some mind. This especially holds true for those who often browse from a public network, e.g. students and those who frequently travel, since public networks are a common reservoir of targets for malicious actors. Sure enough, [according to Google](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-0609>), this vulnerability is reported to have been exploited numerous times in the wild. But we all work from home now so no big deal, right? (I\u2019m hoping this comment does NOT age well).\n\n### What can I do?\n\n[Update Chrome](<https://support.google.com/chrome/answer/95414?hl=en&co=GENIE.Platform%3DDesktop>) to version [98.0.4758.102](<https://chromereleases.googleblog.com/2022/02/stable-channel-update-for-desktop_14.html>) or later, if you have not done so already. Checking the current version of Chrome is as simple as pasting \u201cchrome://version\u201d into the search bar.\n\n### The Gold Standard\n\nAs with iOS, etc., turning on automatic updates for Chrome is a good practice. Set it and forget. \n\n \n\n\n## CVE-2022-24086: All your e-commerce belongs to\u2026.?\n\n### What is it?\n\nYou can be forgiven for having never heard of Magento; avoiding PHP back ends like Ebola seems like decent practice. It turns out Magento is an open-source e-commerce platform which was bought by Adobe in 2018 and now forms the backbone of Adobe Commerce. Due to a lack of proper input validation (CWE-20, if you care) during the checkout stage of a transaction, an attacker can use Adobe Commerce\u2014or the open-source release of Magento that parallels it\u2014to achieve unauthenticated RCE with the same privileges as the corresponding server process. So, if Magento is running as root, this is about as bad as it gets.\n\n### Who cares?\n\nWell, if your platform relies on Adobe Commerce or open-source Magento, consider yourself vulnerable\u2014all unpatched versions of each are affected. Not to mention, CVE-2022-24086 has been actively exploited in the wild.\n\nAs of this writing, there is no complete publicly-available proof of concept, although a redacted version of a working POC (seen below) created by researchers with [Positive Technologies Offensive Team](<https://swarm.ptsecurity.com/>) has been released on [Twitter](<https://twitter.com/ptswarm/status/1494240197915123713>) and distributed widely, which illustrates the leaking of \u201c/etc/passwd\u201d on a vulnerable host.\n\n \n\n\n### What can I do?\n\nPatch, and patch quickly. Time is of the essence! But be sure to follow the [instructions from Adobe](<https://helpx.adobe.com/security/products/magento/apsb22-12.html#Summary>) with care: there are two patches which must be applied in sequence, one to address [CVE-2022-24086](<https://vulners.com/cve/CVE-2022-24086>) and another to fix the near-identical follow-on issue tracked as [CVE-2022-24087](<https://sensorstechforum.com/cve-2022-24087-adobe-magento/>). Both patches are required to make sure that your platform is safe from exploitation of this vulnerability.\n\n### The Gold Standard\n\nStay abreast on the latest impactful vulnerabilities throughout the industry; or you just might see a piece of your own infrastructure featured in the latest CVE. Our [security bulletins](<https://www.mcafee.com/enterprise/en-us/threat-center/product-security-bulletins.html>) are a great place to start.\n\n \n\n\n## CVE-2022-22536: A Perfect 10!\n\n### What is it?\n\nDoes anyone have a clue what SAP stands for? I\u2019ve always wondered but never been able to demystify the potential acronym. This month it could be confused with a Strikingly Attackable Platform thanks to CVE-2022-22536. The bug exists in the SAP Internet Communication Manager (ICM) when the webserver hosting the ICM is sitting behind a proxy. An attacker can use a technique called [HTTP Response Smuggling](<https://www.whitehatsec.com/glossary/content/http-response-smuggling>) to poison the proxy\u2019s web cache and ICM response queue. Upon an unexpecting user visiting the website and making a GET request for the page, they will download the attacker\u2019s malicious JavaScript instead of the intended webpage. A more detailed (and colorful!) explanation of the attack mechanics is available on the [Onapsis website](<https://onapsis.com/icmad-sap-cybersecurity-vulnerabilities?utm_campaign=2022-Q1-global-ICM-campaign-page&utm_medium=website&utm_source=third-party&utm_content=CISA-alert#download>), for the price of your email, of course.\n\n### Who cares?\n\nSAP in January of 2022 proudly [reported](<https://www.sap.com/documents/2017/04/4666ecdd-b67c-0010-82c7-eda71af511fa.html>) that 99 of 100 of the largest companies in the world were SAP customers with over [230 million cloud users](<https://www.sap.com/about/company/what-is-sap.html>). Couple that statistic with the fact that every SAP application sitting behind any kind of proxy with standard configuration will be vulnerable to this bug, there is a good chance you might need to cancel your weekend plans. Although we don\u2019t put much stock in [CVSS score](<https://nvd.nist.gov/vuln-metrics/cvss>) for this publication, it's worth noting this scored the magical unicorn rating of a perfect 10 and was able to garner special attention from our friends at [CISA](<https://www.cisa.gov/uscert/ncas/current-activity/2022/02/08/critical-vulnerabilities-affecting-sap-applications-employing>).\n\n### What can I do?\n\nIf in doubt as to whether or not your SAP server is vulnerable, the good people at [Onapsis](<https://onapsis.com/>), who discovered the vulnerability, released a Python-based [scanning tool](<https://wiki.scn.sap.com/wiki/display/PSR/SAP+Security+Patch+Day+-+February+2022>) with a complete CLI. Or, if you have the version number of your NetWeaver, Web Dispatcher, etc., you can simply cross-reference it with [SAP\u2019s official list](<https://wiki.scn.sap.com/wiki/display/PSR/SAP+Security+Patch+Day+-+February+2022>) of vulnerable versions. Don\u2019t want a call at 2 a.m. about a breach? Take the time to download and install the patches for your SAP products today!\n\n### The Gold Standard\n\nUnfortunately, not every vulnerability can be adequately addressed by network security products, and this vulnerability happens to be one of those cases. Your best bet is to follow the mitigations mentioned above and keep your servers up to date.\n", "cvss3": {}, "published": "2022-03-02T00:00:00", "type": "trellix", "title": "The Bug Report - February 2022 Edition", "bulletinFamily": "info", "cvss2": {}, "cvelist": ["CVE-2022-0609", "CVE-2022-22536", "CVE-2022-22620", "CVE-2022-24086", "CVE-2022-24087"], "modified": "2022-03-02T00:00:00", "id": "TRELLIX:73420774AE3767CFB11F493B41572174", "href": "https://www.trellix.com/content/mainsite/en-us/about/newsroom/stories/research/the-bug-report-february-2022.html", "cvss": {"score": 0.0, "vector": "NONE"}}], "malwarebytes": [{"lastseen": "2022-02-14T11:27:09", "description": "German enterprise software maker SAP has patched three critical vulnerabilities affecting Internet Communication Manager (ICM), a core component of SAP business applications. Customers are urged by both [SAP](<https://blogs.sap.com/2022/02/08/sap-partners-with-onapsis-to-identify-and-patch-cybersecurity-vulnerabilities/>) and [CISA](<https://www.cisa.gov/uscert/ncas/current-activity/2022/02/08/critical-vulnerabilities-affecting-sap-applications-employing>) to address these critical vulnerabilities as soon as possible.\n\nOn February 8, SAP released 14 new security notes and security researchers from Onapsis, in coordination with SAP, released a [Threat Report](<https://onapsis.com/icmad-sap-cybersecurity-vulnerabilities>) describing SAP ICM critical vulnerabilities, [CVE-2022-22536](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-22536>), [CVE-2022-22532](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-22532>), and [CVE-2022-22533](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-22533>). Onapsis also provides an [open source tool](<https://github.com/Onapsis/onapsis_icmad_scanner>) to identify if a system is vulnerable and needs to be patched.\n\n## CVE-2022-22536\n\nThe most important vulnerability in this report is CVE-2022-22536, one of the ICMAD vulnerabilities. The ICMAD vulnerabilities are particularly critical because the issues exist by default in the SAP Internet Communication Manager (ICM). The ICM is one of the most important components of a SAP NetWeaver application server and is present in most SAP products. It is a critical part of the overall SAP technology stack, connecting SAP applications with the Internet.\n\nCVE-2022-22536 is a request smuggling and request concatenation in SAP NetWeaver, SAP Content Server and SAP Web Dispatcher. This vulnerability scored a [CVSS](<https://blog.malwarebytes.com/malwarebytes-news/2020/05/how-cvss-works-characterizing-and-scoring-vulnerabilities/>) rating of 10 out of 10. The high score is easy to explain. A simple HTTP request, indistinguishable from any other valid message and without any kind of authentication, is enough for a successful exploitation of the vulnerability.\n\n## Other vulnerabilities\n\nSome of the other \u201chigh scorers\u201d are [Log4j](<https://blog.malwarebytes.com/exploits-and-vulnerabilities/2021/12/log4j-zero-day-log4shell-arrives-just-in-time-to-ruin-your-weekend/>) related vulnerabilities, and a security update for the browser control Google Chromium delivered with SAP Business Client. The other two ICMAD vulnerabilities identified as CVE-2022-22532 and CVE-2022-22533 received scores of 8.1 and 7.5, respectively.\n\n## Scan tool\n\nOn [GitHub](<https://github.com/Onapsis/onapsis_icmad_scanner>) Onapsis published a Python script that can be used to check if a SAP system is affected by CVE-2022-22536.\n\nA [Shodan scan](<https://www.shodan.io/search?query=server%3A+SAP+NetWeaver+Application+Server>) shows there are more than 5,000 SAP NetWeaver servers currently connected to the Internet and exposed to attacks until the patch is applied.\n\n## Mitigation\n\nSAP and Onapsis are currently unaware of any customer breaches that relate to these vulnerabilities, but strongly advise impacted organizations to immediately apply Security Note 3123396 (which covers CVE-2022-22536) to their affected SAP applications as soon as possible.\n\nThe Cybersecurity &amp; Infrastructure Security Agency (CISA) warned that customers who fail to do so will be exposing themselves to ransomware attacks, the theft of sensitive data, financial fraud, and disruption or halt of business operations.\n\nThe post [SAP customers are urged to patch critical vulnerabilities in multiple products](<https://blog.malwarebytes.com/exploits-and-vulnerabilities/2022/02/sap-customers-are-urged-to-patch-critical-vulnerabilities-in-multiple-products/>) appeared first on [Malwarebytes Labs](<https://blog.malwarebytes.com>).", "cvss3": {"exploitabilityScore": 3.9, "cvssV3": {"baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "CHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "baseScore": 10.0, "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H", "version": "3.1", "userInteraction": "NONE"}, "impactScore": 6.0}, "published": "2022-02-10T08:58:36", "type": "malwarebytes", "title": "SAP customers are urged to patch critical vulnerabilities in multiple products", "bulletinFamily": "blog", "cvss2": {"severity": "HIGH", "exploitabilityScore": 10.0, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "baseScore": 10.0, "vectorString": "AV:N/AC:L/Au:N/C:C/I:C/A:C", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "impactScore": 10.0, "acInsufInfo": false, "obtainUserPrivilege": false}, "cvelist": ["CVE-2021-22532", "CVE-2021-22533", "CVE-2021-22536", "CVE-2022-22532", "CVE-2022-22533", "CVE-2022-22536"], "modified": "2022-02-10T08:58:36", "id": "MALWAREBYTES:A40F87C53D5487E9D81FB6A8F62AF633", "href": "https://blog.malwarebytes.com/exploits-and-vulnerabilities/2022/02/sap-customers-are-urged-to-patch-critical-vulnerabilities-in-multiple-products/", "cvss": {"score": 10.0, "vector": "AV:N/AC:L/Au:N/C:C/I:C/A:C"}}, {"lastseen": "2022-08-23T00:02:12", "description": "On Thursday, CISA (the US Cybersecurity and Infrastructure Security Agency) updated [its catalog of actively exploited vulnerabilities](<https://www.cisa.gov/known-exploited-vulnerabilities-catalog>) by adding seven new entries. These flaws were found in Apple, Google, Microsoft, Palo Alto Networks, and SAP products. CISA set the due date for everyone to patch the weaknesses by September 8, 2022.\n\nCVE-2022-22536, an SAP flaw with the highest risk score of 10, is one of the seven. We wrote about it in February, and thankfully, SAP addressed the issue fairly quickly, too, by issuing a patch. CISA even mentioned that if customers fail to patch CVE-2022-22536, they could be exposed to ransomware attacks, data theft, financial fraud, and other business disruptions that'd cost them millions.\n\n[**CVE-2022-32893**](<https://cve.report/CVE-2022-32893>) and [**CVE-2022-32894**](<https://cve.report/CVE-2022-32894>), the two zero-day, out-of-bounds write vulnerabilities affecting iOS, iPadOS, and macOS, continue to [headline](<https://www.malwarebytes.com/blog/news/2022/08/urgent-update-for-macos-and-ios-two-actively-exploited-zero-days-fixed>) as of this writing. These are serious flaws that, if left unpatched, could allow anyone to take control of vulnerable Apple systems. Apple already released fixes for these from the following support pages:\n\n * [About the security content of iOS 15.6.1 and iPadOS 15.6.1](<https://support.apple.com/en-gb/HT213412>)\n * [About the security content of macOS Monterey 12.5.1](<https://support.apple.com/en-gb/HT213413>)\n * [About the security content of Safari 15.6.1](<https://support.apple.com/en-us/HT213414>)\n\nThe Google Chrome flaw with high severity, **[CVE-2022-2856](<https://www.malwarebytes.com/blog/news/2022/08/update-chrome-now-google-issues-patch-for-zero-day-spotted-in-the-wild>)**, is also [confirmed](<https://www.forbes.com/sites/daveywinder/2022/08/20/google-confirms-chrome-zero-day-5-as-attacks-begin-update-now/>) to be targeted by hackers. As with other zero-days, technical details about it are light, but the [advisory](<https://chromereleases.googleblog.com/2022/08/stable-channel-update-for-desktop_16.html>) states that the flaw is an \"insufficient validation of untrusted input in Intents.\" The [Intents](<https://developers.google.com/assistant/conversational/intents>) technology works in the background and is involved in processing user input or handling a system event. If this flaw is exploited, anyone could create a malicious input that Chrome may validate incorrectly, leading to arbitrary code execution or system takeover.\n\nGoogle already patched this. While Chrome should've updated automatically, it is recommended to force an update check to ensure the patch is applied.\n\nMicrosoft also has patches available for **[CVE-2022-21971](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-21971>)** and **[CVE-2022-26923](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-26923>)** in February and May, respectively. The former was given an \"exploitation less likely\" probability, but that has already changed--a [proof-of-concept (PoC)](<https://www.malwarebytes.com/glossary/proof-of-concept>) has been available since March. PoC exploits were also made public for the latter Microsoft flaw. However, these were released after Microsoft had already pushed out a patch.\n\nPalo Alto Networks's is the oldest among the new vulnerabilities added to the catalog. Discovered in 2017, **[CVE-2017-15944](<https://nvd.nist.gov/vuln/detail/CVE-2017-15944>)** has a severity rating of 9.8 (Critical). Once exploited, attackers could perform remote code execution on affected systems. You can read more about this flaw on [Palo Alto's advisory page](<https://security.paloaltonetworks.com/CVE-2017-15944>).\n\nMalwarebytes advises readers to apply patches to these flaws if they use products of the companies we mentioned.

This month I decided NOT to make an episode completely dedicated to Microsoft Patch Tuesday. Instead, this episode will be an answer to the question of how my Vulnerability Management month went. A retrospection of some kind.\n\nAlternative video link (for Russia): <https://vk.com/video-149273431_456239134>\n\n## GitHub exploits and Vulristics\n\nThis month I made some improvements to my Vulristics vulnerability prioritization tool. These changes relate to the use of exploit data on Github. We all know that exploits are often posted on GitHub. But how adequate is this source in order to evaluate the exploitability?\n\n### PoC in Github\n\nFor example, there is an interesting [PoC in GitHub](<https://github.com/nomi-sec/PoC-in-GitHub>) repository on github. It contains the results of an automated search for exploits of CVE vulnerabilities on GitHub. There are currently PoCs for 4484 CVE IDs. \n\nDistribution by years:\n \n \n CVE-1999-_: 4 CVE-2000-_: 4 \n CVE-2001-_: 10 CVE-2002-_: 14 \n CVE-2003-_: 6 CVE-2004-_: 9 \n CVE-2005-_: 7 CVE-2006-_: 13 \n CVE-2007-_: 18 CVE-2008-_: 21 \n CVE-2009-_: 22 CVE-2010-_: 25 \n CVE-2011-_: 27 CVE-2012-_: 39 \n CVE-2013-_: 64 CVE-2014-_: 128 \n CVE-2015-_: 144 CVE-2016-_: 185 \n CVE-2017-_: 323 CVE-2018-_: 407 \n CVE-2019-_: 504 CVE-2020-_: 684 \n CVE-2021-_: 747 CVE-2022-_: 739 \n CVE-2023-*: 340\n\nThe total number of CVEs is growing, and so is the number of exploitable CVEs.  But no one guarantees that PoC is functional and that there are no rickrolls or malware. Be careful. \n\nFor example, it contains Office RCE vulnerability (CVE-2023-36884) from the July Patch Tuesday. But if you look closely, everything is not so rosy.  Let&#x27;s see.\n\n 1.  Maxwitat/CVE-2023-36884-Scripts-for-Intune-Remediation-SCCM-Compliance-Baseline - script for remediation\n 2.  deepinstinct/Storm0978-RomCom-Campaign - IOCs\n 3.  zerosorai/CVE-2023-36884 - remediation utility\n 4.  tarraschk/CVE-2023-36884-Checker - vulnerability detection script\n 5.  or2me/CVE-2023-36884_patcher - remediation utility\n 6.  ToddMaxey/CVE-2023-36884 - script for remediation\n 7.  ridsoliveira/Fix-CVE-2023-36884 - script for remediation\n 8.  raresteak/CVE-2023-36884 - information for remediation\n\nThere is no POC yet. \n\nSo &quot;PoC in GitHub&quot; would be more appropriate to call &quot;CVE mentions in GitHub&quot;. It will highlight mentions of CVEs, but, of course, it will not show the context. Then only manual analysis or some automated classification will help you.\n\n### Vulristics vulners-use-github-exploits-flag\n\nThe ambiguity of exploitation data on GitHub is also bad for my Vulristics reports. For high-profile vulnerabilities, such as Zerologon (CVE-2020-1472), there are too many references to GitHub in the report, most of which are not related to exploits. \n\n\n\nAnd it is very difficult to automatically understand which repositories contain exploits and which contain irrelevant content. And, **as a rule**, it is not really necessary. Fully functional exploit will most likely end up in specialized exploit packs, although it may happen with some delay.\n\n\n\nTherefore, I think Vulristics users should be able to generate both reports containing as much information about exploits as possible (although it will be littered) and reports that take into account only known exploit packs.\n\nI have added the option `--vulners-use-github-exploits-flag`, which can be either `True` or `False`. The default value is `True`.\n\nI also added [source] links.\n\n### Exceptions\n\nAn exploit from GitHub, **as a rule**, ends up in a specialized exploit pack over time, BUT NOT ALWAYS! For example, **Command Injection** - SAP NetWeaver (CVE-2022-22536).\n\n\n\nWe see that exploits for this vulnerability are available only on the GitHub. And, judging by the description, they are valid. \n\n\n\nAnd if we generate a Vulristics report with `--vulners-use-github-exploits-flag \"False\"`, then we will lose this valuable information. \n\n\n\nSo be aware and use the option with caution. \n\n## VM vendors updates\n\n### Qualys First-Party Application Risk Detection and Remediation\n\nIn early August, Qualys [introduced new capabilities](<https://blog.qualys.com/product-tech/2023/08/03/qualys-expands-cloud-platform-for-first-party-application-risk-detection-and-remediation>) for analyzing the vulnerabilities of self-written (First-Party) and open source applications.\n\n 1. Custom Assessment and Remediation (CAR) is a mechanism for adding your own detection scripts, including PowerShell and Python scripts. You can write your own detection script (for example, using the versions that the application security guys told you), add it to Qualys and get a list of vulnerable hosts. Such vulnerabilities will have a QID and can be treated as vulnerabilities detected by Qualys itself.\n 2. Runtime Software Composition Analysis (SCA). During a vulnerability scan, not only the software itself is checked, but also the libraries used by this software. In fact, Qualys Agent runs through the file system and searches / analyzes library files (including Log4j). This is not a super new feature. I have seen such detections in Microsoft Defender for Endpoint for a long time. But apparently it becomes a mandatory feature.\n\n### Tenable ExposureAI\n\n[Tenable announced](<https://www.tenable.com/press-releases/tenable-makes-generative-ai-security-tools-available-to-the-research-community>) Vulnerability (Exposure) Management with generative AI similar to ChatGPT. The product (or rather technology) will be called [ExposureAI](<https://www.tenable.com/solutions/exposure-ai>) and will be available as part of Tenable One.\n\nMain features:\n\n 1. It will be possible to make requests in a natural language.\n 2. It will be possible to generate human-readable descriptions of Attack Path scenarios (this saves time when preparing reports).\n 3. It will be possible to see insights &quot;what needs to be done first&quot;.\n\nAs with Cyclops Security, which announced similar functionality a little earlier, it all depends on how smart the system turns out to be and how bad mistakes it makes.\n\n### SC Awards and Rapid7\n\n[SC Awards](<https://www.scmagazine.com/2023-sc-award-winners>) continues to be fun. This year Rapid7 InsightVM received &quot;Best Vulnerability Management Solution&quot;. [In the nomination](<https://www.scmagazine.com/news/2023-sc-awards-finalists-best-vulnerability-management-solution#>) there was Tenable - it&#x27;s ok. Do you know what other 3 giants and innovators of the VM market were there?\n\n Palo Alto Networks Prisma Cloud - cloud-native application protection platform  \n Lacework - cloud security platform  \n Coalfire Ransomware Simulation-as-a-Service (RSaaS) \n\nHave the contest organizers heard of Qualys VM? \n\nApparently, so that Tenable would not be offended, they were given &quot;Best Risk / Policy Management Solution&quot; (Qualys was also in this nomination) and &quot;Best Security Company&quot;. The company is the best, but apparently their VM is so-so, Rapid7&#x27;s solution is better.  The only pity is that Rapid7 seems to have problems with sales of this best VM solution. &quot;[Rapid7 will lay off](<https://www.crn.com/news/security/rapid7-to-make-surprising-layoffs-of-hundreds-as-it-invests-in-msps-mdr>) about 18 per cent of its workforce, around 470 employees, with significant cuts to sales and engineering \u2013 as well as permanently close some office locations&quot;.\n\nNow let&#x27;s talk about vulnerabilities.\n\n## Anglo-Saxon vulnerability lists\n\nAnglo-Saxon state security agencies from 5 countries issued a joint advisory &quot;[2022&#x27;s Top Routinely Exploited Vulnerabilities](<https://www.cisa.gov/sites/default/files/2023-08/aa23-215a_joint_csa_2022_top_routinely_exploited_vulnerabilities.pdf>)&quot;. I took this report, wrote out the CVE references and released 2 Vulristics reports:\n\n 1. [TOP 12 vulnerabilities](<https://avleonov.com/vulristics_reports/aa23-215a_top12_report_with_comments_ext_img.html>)\n 2. [Extended with all vulnerabilities (42) from the advisory ](<https://avleonov.com/vulristics_reports/aa23-215a_report_with_comments_ext_img.html>)\n\nIn the Top 12 Vulnerabilities, all CVEs have links to exploits and signs of exploitation in the wild. All of them are Urgent, except for one, because it is EoP in the not-so-common Workspace One. The most critical are RCEs in Apache Log4j2, Microsoft Exchange, and Confluence.\n\nIn the extended report, all CVEs have the sign of exploitation in the wild, but there are 6 vulnerabilities without links to exploits and therefore with Critical/High criticality. The most critical are RCEs in Apache HTTP Server, Apache Log4j2, Windows RDP and Microsoft Exchange.\n\nIt is worth noting that the extended list contains such Oldies But Goodies vulnerabilities as:\n\n * [Zerologon](<https://avleonov.com/2020/09/30/microsoft-patch-tuesday-september-2020-zerologon-and-other-exploits-rces-in-sharepoint-and-exchange/>) (CVE-2020-1472). A vulnerability in the cryptography of Microsoft\u2019s Netlogon process that allows an attack against Microsoft Active Directory domain controllers\n\n\n\n * Microsoft Office RCE (CVE-2017-11882). The PoC for this vulnerability appeared a week after the publication in 2017 and since then, for more than 5 years, it has been actively exploited. \n\n\n\nCompared to [last year advisory](<https://avleonov.com/2022/10/21/joint-advisory-aa22-279a-and-vulristics/>), GitLab and exotics like Hikvision and Buffalo are gone. The set of CVEs looks better.\n\nCommands for those who want to build a report themselves in [Vulristics](<https://github.com/leonov-av/vulristics>) using [comments for CVEs](<https://avleonov.com/vulristics_reports/AA23-215A_comments.txt>) from AA23-215A.\n \n \n $ cat AA23-215A_comments.txt | grep -v \"30 Additional\" | egrep -o \"CVE-[0-9]-[0-9]\" | sort | uniq > AA23-215A_cves_top12.txt\n $ cat AA23-215A_comments.txt | egrep -o \"CVE-[0-9]-[0-9]\" | sort | uniq > AA23-215A_cves.txt\n \n $ python3 vulristics.py --report-type \"cve_list\" --cve-project-name \"AA23-215A\" --cve-list-path \"AA23-215A_cves.txt\" --cve-comments-path \"AA23-215A_comments.txt\" --cve-data-sources \"ms,nvd,epss,vulners,attackerkb\" --rewrite-flag \"True\"\n $ python3 vulristics.py --report-type \"cve_list\" --cve-project-name \"AA23-215A_top12\" --cve-list-path \"AA23-215A_cves_top12.txt\" --cve-comments-path \"AA23-215A_comments.txt\" --cve-data-sources \"ms,nvd,epss,vulners,attackerkb\" --rewrite-flag \"False\"\n\nFunny detail: 8 agencies from 5 countries released this, but there was no one who carefully read and noticed that in several places the identifier for Log4Shell is written as &quot;CVE-2021- 44228&quot; with a space. Both [in pdf](<https://www.cisa.gov/sites/default/files/2023-08/aa23-215a_joint_csa_2022_top_routinely_exploited_vulnerabilities.pdf>), and in [the web-version](<https://www.cisa.gov/news-events/cybersecurity-advisories/aa23-215a>). \n\n## August Microsoft Patch Tuesday\n\nMy impressions of the August Microsoft Patch Tuesday - nothing special. \n\n\n\n * All vulnerabilities: 103\n * Urgent: 0\n * Critical: 1\n * High: 33\n * Medium: 69\n * Low: 0\n\nFormally, the most critical vulnerability is **Denial of Service** - .NET and Visual Studio (CVE-2023-38180), because there are signs of exploitation. There are no details, but it is somehow doubtful. \n\n\n\nNo more vulnerabilities with public exploits or signs of exploitation.\n\nSeveral **Remote Code Executions** - Microsoft Exchange (CVE-2023-35368, CVE-2023-38185, CVE-2023-35388, CVE-2023-38182). 3 of them definitely require authentication, one is unclear. This authentication can potentially be obtained through **Elevation of Privilege** - Microsoft Exchange (CVE-2023-21709) - &quot;This vulnerability allows a remote, unauthenticated attacker to log in as another user&quot;. It&#x27;s better to patch! \n\n**Remote Code Execution** - Microsoft Teams (CVE-2023-29328, CVE-2023-29330). Fortunately, in Russia it&#x27;s not popular anymore.\n\nThere is also a bunch of EoPs in the Windows kernel&amp;components.\n\nFull report: [ms_patch_tuesday_august2023_report](<https://avleonov.com/vulristics_reports/ms_patch_tuesday_august2023_report_with_comments_ext_img.html>)\n\n## Other important vulnerabilities\n\nAmong other vulnerabilities of this month, I would like to highlight:\n\n * Actively exploited since April 2023 WinRAR Extension Spoofing (CVE-2023-38831), which also has a public exploit. I highly recommend installing the WinRAR 6.23 update, which also fixes the potentially dangerous RCE CVE-2023-40477.\n\n\n\n * [Numerous vulnerabilities](<https://supportportal.juniper.net/s/article/2023-08-Out-of-Cycle-Security-Bulletin-Junos-OS-SRX-Series-and-EX-Series-Multiple-vulnerabilities-in-J-Web-can-be-combined-to-allow-a-preAuth-Remote-Code-Execution?language=en_US>) in the J-Web component (web console) of the Juniper Networks Junos operating system on SRX and EX series devices. These are the vulnerabilities that lead to RCE and for them there is a [detailed review](<https://labs.watchtowr.com/cve-2023-36844-and-friends-rce-in-juniper-firewalls/>) and a [PoC](<https://labs.watchtowr.com/cve-2023-36844-and-friends-rce-in-juniper-firewalls/>).\n\n", "cvss3": {"exploitabilityScore": 3.9, "cvssV3": {"baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "CHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "baseScore": 10.0, "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H", "version": "3.1", "userInteraction": "NONE"}, "impactScore": 6.0}, "published": "2023-08-30T16:15:31", "type": "avleonov", "title": "August 2023: GitHub PoCs, Vulristics, Qualys First-Party, Tenable ExposureAI, SC Awards and Rapid7, Anglo-Saxon list, MS Patch Tuesday, WinRAR, Juniper", "bulletinFamily": "blog", "cvss2": {"severity": "HIGH", "exploitabilityScore": 10.0, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "baseScore": 10.0, "vectorString": "AV:N/AC:L/Au:N/C:C/I:C/A:C", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "impactScore": 10.0, "acInsufInfo": false, "obtainUserPrivilege": false}, "cvelist": ["CVE-2017-11882", "CVE-2020-1472", "CVE-2022-22536", "CVE-2023-21709", "CVE-2023-29328", "CVE-2023-29330", "CVE-2023-35368", "CVE-2023-35388", "CVE-2023-36844", "CVE-2023-36884", "CVE-2023-38180", "CVE-2023-38182", "CVE-2023-38185", "CVE-2023-38831", "CVE-2023-40477"], "modified": "2023-08-30T16:15:31", "id": "AVLEONOV:7E0DF6DEBB35FB55F6B4D33A7262A422", "href": "https://avleonov.com/2023/08/30/august-2023-github-pocs-vulristics-qualys-first-party-tenable-exposureai-sc-awards-and-rapid7-anglo-saxon-list-ms-patch-tuesday-winrar-juniper/", "cvss": {"score": 10.0, "vector": "AV:N/AC:L/Au:N/C:C/I:C/A:C"}}], "ics": [{"lastseen": "2023-12-06T21:19:51", "description": "### **SUMMARY**\n\nThe following cybersecurity agencies coauthored this joint Cybersecurity Advisory (CSA):\n\n * United States: The Cybersecurity and Infrastructure Security Agency (CISA), National Security Agency (NSA), and Federal Bureau of Investigation (FBI)\n * Australia: Australian Signals Directorate\u2019s Australian Cyber Security Centre (ACSC)\n * Canada: Canadian Centre for Cyber Security (CCCS)\n * New Zealand: New Zealand National Cyber Security Centre (NCSC-NZ) and Computer Emergency Response Team New Zealand (CERT NZ)\n * United Kingdom: National Cyber Security Centre (NCSC-UK)\n\nThis advisory provides details on the Common Vulnerabilities and Exposures (CVEs) routinely and frequently exploited by malicious cyber actors in 2022 and the associated Common Weakness Enumeration(s) (CWE). In 2022, malicious cyber actors exploited older software vulnerabilities more frequently than recently disclosed vulnerabilities and targeted unpatched, internet-facing systems.\n\nThe authoring agencies strongly encourage vendors, designers, developers, and end-user organizations to implement the recommendations found within the Mitigations section of this advisory\u2014including the following\u2014to reduce the risk of compromise by malicious cyber actors.\n\n * **Vendors, designers, and developers**: Implement [secure-by-design and -default principles and tactics](<https://www.cisa.gov/resources-tools/resources/secure-by-design-and-default> \"Security-by-Design and -Default\" ) to reduce the prevalence of vulnerabilities in your software. \n * **Follow the Secure Software Development Framework (SSDF)**, also known as [SP 800-218](<https://csrc.nist.gov/publications/detail/sp/800-218/final> \"NIST SP 800-218\" ), and implement secure design practices into each stage of the software development life cycle (SDLC).

Proof of concept (PoC) code was publicly available for many of the software vulnerabilities or vulnerability chains, likely facilitating exploitation by a broader range of malicious cyber actors.\n\nMalicious cyber actors generally have the most success exploiting known vulnerabilities within the first two years of public disclosure\u2014the value of such vulnerabilities gradually decreases as software is patched or upgraded. Timely patching reduces the effectiveness of known, exploitable vulnerabilities, possibly decreasing the pace of malicious cyber actor operations and forcing pursuit of more costly and time-consuming methods (such as developing zero-day exploits or conducting software supply chain operations).\n\nMalicious cyber actors likely prioritize developing exploits for severe and globally prevalent CVEs. While sophisticated actors also develop tools to exploit other vulnerabilities, developing exploits for critical, wide-spread, and publicly known vulnerabilities gives actors low-cost, high-impact tools they can use for several years. Additionally, cyber actors likely give higher priority to vulnerabilities that are more prevalent in their specific targets\u2019 networks. Multiple CVE or CVE chains require the actor to send a malicious web request to the vulnerable device, which often includes unique signatures that can be detected through deep packet inspection.\n\n#### **Top Routinely Exploited Vulnerabilities**\n\nTable 1 shows the top 12 vulnerabilities the co-authors observed malicious cyber actors routinely exploiting in 2022:\n\n * [**CVE-2018-13379**](<https://nvd.nist.gov/vuln/detail/CVE-2018-13379> \"CVE-2018-13379\" )**. **This vulnerability, affecting Fortinet SSL VPNs, was also [routinely exploited in 2020](<https://www.cisa.gov/news-events/cybersecurity-advisories/aa21-209a> \"Top Routinely Exploited Vulnerabilities\" ) and [2021](<https://www.cisa.gov/news-events/cybersecurity-advisories/aa22-117a> \"2021 Top Routinely Exploited Vulnerabilities\" ). The continued exploitation indicates that many organizations failed to patch software in a timely manner and remain vulnerable to malicious cyber actors.\n * [**CVE-2021-34473**](<https://nvd.nist.gov/vuln/detail/CVE-2021-34473> \"CVE-2021-34473\" )**, **[**CVE-2021-31207**](<https://nvd.nist.gov/vuln/detail/CVE-2021-31207> \"CVE-2021-31207\" )**, **[**CVE-2021-34523**](<https://nvd.nist.gov/vuln/detail/CVE-2021-34523> \"CVE-2021-34523\" )**.** These vulnerabilities, known as ProxyShell, affect Microsoft Exchange email servers. In combination, successful exploitation enables a remote actor to execute arbitrary code. These vulnerabilities reside within the Microsoft Client Access Service (CAS), which typically runs on port 443 in Microsoft Internet Information Services (IIS) (e.g., Microsoft\u2019s web server). CAS is commonly exposed to the internet to enable users to access their email via mobile devices and web browsers.\n * [**CVE-2021-40539**](<https://nvd.nist.gov/vuln/detail/CVE-2021-40539> \"CVE-2021-40539\" )**.** This vulnerability enables unauthenticated remote code execution (RCE) in Zoho ManageEngine ADSelfService Plus and was linked to the usage of an outdated third-party dependency. Initial exploitation of this vulnerability [began in late 2021](<https://www.cisa.gov/news-events/cybersecurity-advisories/aa21-259a> \"APT Actors Exploiting Newly Identified Vulnerability in ManageEngine ADSelfService Plus\" ) and [continued throughout 2022](<https://media.defense.gov/2022/Oct/06/2003092365/-1/-1/0/Joint_CSA_Top_CVEs_Exploited_by_PRC_cyber_actors_.PDF> \"Top CVEs Actively Exploited By People\u2019s Republic of China State-Sponsored Cyber Actors\" ).\n * [**CVE-2021-26084**](<https://nvd.nist.gov/vuln/detail/CVE-2021-26084> \"CVE-2021-26084\" )**.** This vulnerability, affecting Atlassian Confluence Server and Data Center (a web-based collaboration tool used by governments and private companies) could enable an unauthenticated cyber actor to execute arbitrary code on vulnerable systems. This vulnerability quickly became one of the most routinely exploited vulnerabilities after a PoC was released within a week of its disclosure. Attempted mass exploitation of this vulnerability was observed in September 2021.\n * [**CVE-2021- 44228**](<https://nvd.nist.gov/vuln/detail/CVE-2021-44228> \"CVE-2021-44228\" )**.** This vulnerability, known as Log4Shell, affects Apache\u2019s Log4j library, an open-source logging framework incorporated into thousands of products worldwide. An actor can exploit this vulnerability by submitting a specially crafted request to a vulnerable system, causing the execution of arbitrary code. The request allows a cyber actor to take full control of a system. The actor can then steal information, launch ransomware, or conduct other malicious activity.[[1](<https://www.cisa.gov/news-events/news/apache-log4j-vulnerability-guidance>)] Malicious cyber actors began exploiting the vulnerability after it was publicly disclosed in December 2021, and continued to show high interest in CVE-2021- 44228 through the first half of 2022.\n * [**CVE-2022-22954**](<https://nvd.nist.gov/vuln/detail/CVE-2022-22954> \"CVE-2022-22954\" ), [**CVE-2022-22960**](<https://nvd.nist.gov/vuln/detail/CVE-2022-22960> \"CVE-2022-22960\" )**.** These vulnerabilities allow RCE, privilege escalation, and authentication bypass in VMware Workspace ONE Access, Identity Manager, and other VMware products. A malicious cyber actor with network access could trigger a server-side template injection that may result in remote code execution**. **Exploitation of CVE-2022-22954 and CVE-2022-22960 [began in early 2022](<https://www.cisa.gov/news-events/cybersecurity-advisories/aa22-138b> \"Threat Actors Chaining Unpatched VMware Vulnerabilities for Full System Control\" ) and attempts continued throughout the remainder of the year.\n * [**CVE-2022-1388**](<https://nvd.nist.gov/vuln/detail/CVE-2022-1388> \"CVE-2022-1388\" )**.** This vulnerability allows unauthenticated malicious cyber actors to bypass iControl REST authentication** **on F5 BIG-IP application delivery and security software**.**\n * [**CVE-2022-30190**](<https://nvd.nist.gov/vuln/detail/CVE-2022-30190> \"CVE-2022-30190\" )**.** This vulnerability impacts the Microsoft Support Diagnostic Tool (MSDT) in Windows. A remote, unauthenticated cyber actor could exploit this vulnerability to take control of an affected system.\n * [**CVE-2022-26134**](<https://nvd.nist.gov/vuln/detail/CVE-2022-26134> \"CVE-2022-26134\" ). This critical RCE vulnerability affects Atlassian Confluence and Data Center. The vulnerability, which was likely initially exploited as a zero-day before public disclosure in June 2022, is related to an older Confluence vulnerability ([CVE-2021-26084](<https://nvd.nist.gov/vuln/detail/CVE-2021-26084> \"CVE-2021-26084\" )), which cyber actors also exploited in 2022.\n_Table 1: Top 12 Routinely Exploited Vulnerabilities in

**MITIGATIONS**\n\n#### **Vendors and Developers**\n\nThe authoring agencies recommend vendors and developers take the following steps to ensure their products are secure by design and default:\n\n * **Identify repeatedly exploited classes of vulnerability. **Perform an analysis of both CVEs and known exploited vulnerabilities to understand which classes of vulnerability are identified more than others. Implement appropriate mitigations to eliminate those classes of vulnerability. For example, if a product has several instances of SQL injection vulnerabilities, ensure all database queries in the product use parameterized queries, and prohibit other forms of queries.\n * **Ensure business leaders are responsible for security. **Business leaders should ensure that proactive steps to eliminate entire classes of security vulnerabilities, rather than only making one-off patches when new vulnerabilities are discovered.\n * **Follow the SSDF** ([SP 800-218](<https://csrc.nist.gov/publications/detail/sp/800-218/final> \"NIST SP 800-218\" )_)_ and implement secure design practices into each stage of the SDLC. Pay attention to: \n * Prioritizing the use of memory safe languages wherever possible [[SSDF PW 6.1](<https://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-218.pdf> \"NIST Special Publication 800-218\" )].\n * Exercising due diligence when selecting software components (e.g., software libraries, modules, middleware, frameworks) to ensure robust security in consumer software products [[SSDF PW 4.1](<https://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-218.pdf> \"NIST Special Publication 800-218\" )].\n * Setting up secure development team practices; this includes conducting peer code reviews, working to a common organization secure coding standard, and maintaining awareness of language specific security concerns [[SSDF PW.5.1, PW.7.1, PW.7.2](<https://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-218.pdf> \"NIST Special Publication 800-218\" )].\n * Establishing a [vulnerability disclosure program](<https://www.cyber.gov.au/resources-business-and-government/governance-and-user-education/governance/vulnerability-disclosure-programs-explained> \"Vulnerability Disclosure Programs Explained\" ) to verify and resolve security vulnerabilities disclosed by people who may be internal or external to the organization [[SSDF RV.1.3](<https://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-218.pdf> \"NIST Special Publication 800-218\" )]. As part of this, establish processes to determine root causes of discovered vulnerabilities.\n * Using static and dynamic application security testing (SAST/DAST) tools to analyze product source code and application behavior to detect error-prone practices [[SSDF PW.7.2, PW.8.2](<https://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-218.pdf> \"NIST Special Publication 800-218\" )].\n * Configuring production-ready products to have to most secure settings as default and providing guidance on the risks of changing each setting [[SSDF PW.9.1, PW9.2](<https://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-218.pdf> \"NIST Special Publication 800-218\" )]\n * **Prioritize secure-by-default configurations** such as eliminating default passwords, implementing single sign on (SSO) technology via modern open standards, and providing high-quality audit logs to customers with no additional configuration and at no extra charge.\n * **Ensure published CVEs include the proper CWE field identifying the root cause of the vulnerability **to enable industry-wide analysis of software security and design flaws.\n\nFor more information on designing secure-by-design and -default products, including additional recommended secure-by-default configurations, see joint guide [Shifting the Balance of Cybersecurity Risk: Principles and Approaches for Security-by-Design and -Default](<https://www.cisa.gov/resources-tools/resources/secure-by-design-and-default> \"Security-by-Design and -Default\" ).\n\n#### **End-User Organizations**\n\nThe authoring agencies recommend end-user organizations implement the mitigations below to improve cybersecurity posture on the basis of the threat actors\u2019 activity. These mitigations align with the cross-sector Cybersecurity Performance Goals (CPGs) developed by CISA and the National Institute of Standards and Technology (NIST). The CPGs provide a minimum set of practices and protections that CISA and NIST recommend all organizations implement. CISA and NIST based the CPGs on existing cybersecurity frameworks and guidance to protect against the most common and impactful threats, tactics, techniques, and procedures. Visit CISA\u2019s [Cross-Sector Cybersecurity Performance Goals](<https://www.cisa.gov/cross-sector-cybersecurity-performance-goals> \"Cross-Sector Cybersecurity Performance Goals\" ) for more information on CPGs, including additional recommended baseline protections.\n\n#### **_Vulnerability and Configuration Management_**\n\n * **Update software, operating systems, applications, and firmware on IT network assets in a timely manner** [CPG 1.E]. Prioritize patching [known exploited vulnerabilities](<https://www.cisa.gov/known-exploited-vulnerabilities-catalog> \"Known Exploited Vulnerabilities Catalog\" ), especially those CVEs identified in this CSA, then critical and high vulnerabilities that allow for remote code execution or denial-of-service on internet-facing equipment. For patch information on CVEs identified in this CSA, refer to the appendix. \n * If a patch for a known exploited or critical vulnerability cannot be quickly applied, implement vendor-approved workarounds.\n * Replace end-of-life software (i.e., software no longer supported by the vendor).\n * **Routinely perform automated asset discovery** across the entire estate to identify and catalogue all the systems, services, hardware and software.\n * **Implement a robust patch management process **and centralized patch management system that establishes prioritization of patch applications [CPG 1.A]. \n * Organizations that are unable to perform rapid scanning and patching of internet-facing systems should consider moving these services to mature, reputable cloud service providers (CSPs) or other managed service providers (MSPs). Reputable MSPs can patch applications\u2014such as webmail, file storage, file sharing, and chat and other employee collaboration tools\u2014for their customers. However, MSPs and CSPs can expand their customer\u2019s attack surface and may introduce unanticipated risks, so organizations should proactively collaborate with their MSPs and CSPs to jointly reduce risk [CPG 1.F]. For more information and guidance, see the following resources. \n * CISA Insights Risk Considerations for Managed Service Provider Customers\n * CISA Insights Mitigations and Hardening Guidance for MSPs and Small- and Mid-sized Businesses\n * ACSC advice on [How to Manage Your Security When Engaging a Managed Service Provider](<https://www.cyber.gov.au/resources-business-and-government/maintaining-devices-and-systems/outsourcing-and-procurement/managed-services/how-manage-your-security-when-engaging-managed-service-provider> \"How to Manage Your Security When Engaging a Managed Service Provider\" )\n * **Document secure baseline configurations for all IT/OT components**, including cloud infrastructure. Monitor, examine, and document any deviations from the initial secure baseline [CPG 2.O].\n * **Perform regular secure system backups** and create known good copies of all device configurations for repairs and/or restoration. Store copies off-network in physically secure locations and test regularly [CPG 2.R].\n * **Maintain an updated cybersecurity incident response plan** that is tested at least annually and updated within a risk informed time frame to ensure its effectiveness [CPG 2.S].\n\n#### **_Identity and Access Management_**\n\n * **Enforce phishing-resistant multifactor authentication (MFA) for all users**, without exception. [CPG 2.H].\n * **Enforce MFA on all VPN connections**. If MFA is unavailable, require employees engaging in remote work to use strong passwords [CPG 2.A, 2.B, 2.C, 2.D, 2.G].\n * **Regularly review, validate, or remove privileged accounts** (annually at a minimum) [CPG 2.D, 2.E].\n * **Configure access control under the principle of least privilege** [CPG 2.Q]. \n * Ensure software service accounts only provide necessary permissions (least privilege) to perform intended functions (using non-administrative privileges where feasible). \n**Note:** See CISA\u2019s Capacity Enhancement Guide \u2013 Implementing Strong Authentication and ACSC\u2019s guidance on [Implementing Multi-Factor Authentication](<https://www.cyber.gov.au/resources-business-and-government/maintaining-devices-and-systems/system-hardening-and-administration/system-hardening/implementing-multi-factor-authentication> \"Implementing Multi-Factor Authentication\" ) for more information on authentication system hardening.\n\n#### **_Protective Controls and Architecture_**\n\n * **Properly configure and secure internet-facing network devices**, disable unused or unnecessary network ports and protocols, encrypt network traffic, and disable unused network services and devices [CPG 2.V, 2.W, 2X]. \n * Harden commonly exploited enterprise network services, including Link-Local Multicast Name Resolution (LLMNR) protocol, Remote Desktop Protocol (RDP), Common Internet File System (CIFS), Active Directory, and OpenLDAP.\n * Manage Windows Key Distribution Center (KDC) accounts (e.g., KRBTGT) to minimize Golden Ticket attacks and Kerberoasting.\n * Strictly control the use of native scripting applications, such as command-line, PowerShell, WinRM, Windows Management Instrumentation (WMI), and Distributed Component Object Model (DCOM).\n * **Implement Zero Trust Network Architecture (ZTNA)** to limit or block lateral movement by controlling access to applications, devices, and databases. Use private virtual local area networks [CPG 2.F, 2.X]. **Note:** See the Department of Defense\u2019s [Zero Trust Reference Architecture](<https://dodcio.defense.gov/Portals/0/Documents/Library/\\(U\\)ZT_RA_v2.0\\(U\\)_Sep22.pdf> \"Department of Defense \\(DoD\\) Zero Trust Reference Architecture\" ) for additional information on Zero Trust.\n * **Continuously monitor the attack surface** and investigate abnormal activity that may indicate cyber actor or malware lateral movement [CPG 2.T]. \n * Use security tools, such as endpoint detection and response (EDR) and security information and event management (SIEM) tools. Consider using an information technology asset management (ITAM) solution to ensure EDR, SIEM, vulnerability scanner, and other similar tools are reporting the same number of assets [CPG 2.T, 2.V].\n * Use web application firewalls to monitor and filter web traffic. These tools are commercially available via hardware, software, and cloud-based solutions, and may detect and mitigate exploitation attempts where a cyber actor sends a malicious web request to an unpatched device [CPG 2.B, 2.F].\n * Implement an administrative policy and/or automated process configured to monitor unwanted hardware, software, or programs against an allowlist with specified approved versions [CPG 2.Q].\n * Use a network protocol analyzer to examine captured data, including packet-level data.\n\n#### **_Supply Chain Security_**\n\n * **Reduce third-party applications and unique system/application builds**\u2014provide exceptions only if required to support business critical functions [CPG 2.Q].\n * Ensure contracts require vendors and/or third-party service providers to: \n * Provide notification of security incidents and vulnerabilities within a risk informed time frame [CPG 1.G, 1.H, 1.I].\n * Supply a Software Bill of Materials (SBOM) with all products to enhance vulnerability monitoring and to help reduce time to respond to identified vulnerabilities [CPG 4.B].\n * **Ask your software providers to discuss their secure by design program** and to provide links to information about how they are working to remove classes of vulnerabilities, and to set secure default settings.\n\n### **RESOURCES**\n\n * For information on the top vulnerabilities routinely exploited in 2016 through 2019, 2020, and 2021, see: \n * Joint CSA [Top 10 Routinely Exploited Vulnerabilities](<https://www.cisa.gov/news-events/cybersecurity-advisories/aa20-133a> \"Top 10 Routinely Exploited Vulnerabilities\" )\n * Joint CSA [Top Routinely Exploited Vulnerabilities](<https://www.cisa.gov/uscert/ncas/alerts/aa21-209a> \"Top Routinely Exploited Vulnerabilities\" )\n * Joint CSA [2021 Top Routinely Exploited Vulnerabilities](<https://www.cisa.gov/news-events/cybersecurity-advisories/aa22-117a> \"2021 Top Routinely Exploited Vulnerabilities\" )\n * See the appendix for additional partner resources on the vulnerabilities mentioned in this CSA.\n * See ACSC\u2019s [Essential Eight mitigation strategies](<https://www.cyber.gov.au/resources-business-and-government/essential-cyber-security/essential-eight/essential-eight-maturity-model> \"Essential Eight Maturity Model\" ) for additional mitigations.\n * See ACSC\u2019s [Cyber Supply Chain Risk Management](<https://www.cyber.gov.au/resources-business-and-government/maintaining-devices-and-systems/outsourcing-and-procurement/cyber-supply-chains/cyber-supply-chain-risk-management> \"Cyber Supply Chain Risk Management\" ) for additional considerations and advice.\n\n### DISCLAIMER\n\nThe information in this report is being provided \u201cas is\u201d for informational purposes only.
