Windows PowerShell 5.1 isn't impacted by the flaw.\n\nBuilt on the .NET Common Language Runtime (CLR), [PowerShell](<https://docs.microsoft.com/en-us/powershell/scripting/overview?view=powershell-7.1>) is a cross-platform task automation utility that consists of a command-line shell, a scripting language, and a configuration management framework.\n\n\"A remote code execution vulnerability exists in .NET 5 and .NET Core due to how text encoding is performed,\" the company [noted in an advisory](<https://github.com/advisories/GHSA-ghhp-997w-qr28>) published earlier this April, adding that the problem resides in the \"[System.Text.Encodings.Web](<https://docs.microsoft.com/en-us/dotnet/api/system.text.encodings.web?view=net-5.0>)\" package, which provides types for encoding and escaping strings for use in JavaScript, HTML, and URLs.\n\n * System.Text.Encodings.Web (version 4.0.0 - 4.5.0) - Fixed in version 4.5.1\n * System.Text.Encodings.Web (version 4.6.0 - 4.7.1) - Fixed in version 4.7.2\n * System.Text.Encodings.Web (version 5.0.0) - Fixed in version 5.0.1\n\nCVE-2021-26701 was originally addressed by Microsoft as part of its [Patch Tuesday update](<https://thehackernews.com/2021/02/microsoft-issues-patches-for-in-wild-0.html>) for February 2021. Given that there are no workarounds that mitigate the vulnerability, it's highly recommended to update to the latest versions.\n\n \n\n\nFound this article interesting?

Microsoft credited JinQuan, MaDongZe, TuXiaoYi, and LiHao of DBAPPSecurity for discovering and reporting the vulnerability.\n\nIn a separate technical write-up, the researchers said a zero-day exploit leveraging the flaw was detected in a \"very limited number of attacks\" against victims located in China by a threat actor named Bitter APT. The attacks were discovered in December 2020.\n\n\"This zero-day is a new vulnerability which caused by win32k callback, it could be used to escape the sandbox of Microsoft [Internet Explorer] browser or Adobe Reader on the latest Windows 10 version,\" DBAPPSecurity researchers [said](<https://ti.dbappsecurity.com.cn/blog/index.php/2021/02/10/windows-kernel-zero-day-exploit-is-used-by-bitter-apt-in-targeted-attack/>). \"The vulnerability is high quality and the exploit is sophisticated.\"\n\nIt's worth noting that Adobe, as part of its February patch, [addressed](<https://helpx.adobe.com/security/products/acrobat/apsb21-09.html>) a critical buffer overflow flaw in Adobe Acrobat and Reader for Windows and macOS (CVE-2021-21017) that it said could lead to arbitrary code execution in the context of the current user.\n\nThe company also warned of active exploitation attempts against the bug in the wild in limited attacks targeting Adobe Reader users on Windows, mirroring aforementioned findings from DBAPPSecurity.\n\nWhile neither Microsoft nor Adobe has provided additional details, the concurrent patching of the two flaws raises the possibility that the vulnerabilities are being chained to carry out the in-the-wild attacks.\n\n### Netlogon Enforcement Mode Goes Into Effect\n\nMicrosoft's Patch Tuesday update also resolves a number of remote code execution (RCE) flaws in Windows DNS Server (CVE-2021-24078), .NET Core, and Visual Studio (CVE-2021-26701), Microsoft Windows Codecs Library (CVE-2021-24081), and Fax Service (CVE-2021-1722 and CVE-2021-24077).\n\nThe RCE in Windows DNS server component is rated 9.8 for severity, making it a critical vulnerability that, if left unpatched, could permit an unauthorized adversary to execute arbitrary code and potentially redirect legitimate traffic to malicious servers.\n\nMicrosoft is also taking this month to push second round of fixes for the [Zerologon](<https://thehackernews.com/2020/09/detecting-and-preventing-critical.html>) flaw (CVE-2020-1472) that was originally resolved in August 2020, following which [reports of active exploitation](<https://twitter.com/MsftSecIntel/status/1308941504707063808>) targeting unpatched systems emerged in September 2020.\n\nStarting February 9, the domain controller \"[enforcement mode](<https://msrc-blog.microsoft.com/2021/01/14/netlogon-domain-controller-enforcement-mode-is-enabled-by-default-beginning-with-the-february-9-2021-security-update-related-to-cve-2020-1472/>)\" will be [enabled by default](<https://support.microsoft.com/help/4557222#EnablingEnforcementMode>), thus blocking \"vulnerable [Netlogon] connections from non-compliant devices.\"\n\nIn addition, the Patch Tuesday update rectifies two information disclosure bugs \u2014 one in Edge browser for Android (CVE-2021-24100) that could have revealed personally identifiable information and payment information of a user, and the other in Microsoft Teams for iOS (CVE-2021-24114) that could have exposed the Skype token value in the preview URL for images in the app.\n\n### RCE Flaws in Windows TCP/IP Stack\n\nLastly, the Windows maker released a set of fixes affecting its TCP/IP implementation \u2014 consisting of two RCE flaws (CVE-2021-24074 and CVE-2021-24094) and one denial of service vulnerability (CVE-2021-24086) \u2014 that it said could be exploited with a DoS attack.\n\n\"The DoS exploits for these CVEs would allow a remote attacker to cause a stop error,\" Microsoft [said](<https://msrc-blog.microsoft.com/2021/02/09/multiple-security-updates-affecting-tcp-ip/>) in an advisory. \"Customers might receive a blue screen on any Windows system that is directly exposed to the internet with minimal network traffic. Thus, we recommend customers move quickly to apply Windows security updates this month.\"\n\nThe tech giant, however, noted that the complexity of the two TCP/IP RCE flaws would make it hard to develop functional exploits. But it expects attackers to create DoS exploits much more easily, turning the security weakness into an ideal candidate for exploitation in the wild.\n\nTo install the latest security updates, Windows users can head to Start > Settings > Update & Security > Windows Update or by selecting Check for Windows updates.\n\n \n\n\nFound this article interesting?

This is the day when they roll out all the available patches for their software, and their operating systems in particular.\n\nSince there were no less than 56 patches in this month\u2019s issue we will focus on the most important ones. Not that 56 is an awful lot. There were [more than 80 in January](<https://blog.malwarebytes.com/exploits-and-vulnerabilities/2021/01/microsoft-issues-83-patches-one-for-actively-exploited-vulnerability/>).\n\n### Microsoft CVEs by importance\n\nPublicly disclosed computer security flaws are listed in the Common Vulnerabilities and Exposures (CVE) database. Its goal is to make it easier to share data across separate vulnerability capabilities (tools, databases, and services). The most notable CVE\u2019s in this update were:\n\n * [CVE-2021-1732](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-1732>) Windows Win32k elevation of privilege (EoP) vulnerability. This one we listed first as it\u2019s actively exploited in the wild. With a EoP vulnerability attackers can raise their authorization permissions beyond those initially granted. For example, if an attacker gains access to a system but only has read-only permissions they can use an EoP vulnerability to raise them to \u201cread and write\u201d, giving them an option to make unwanted changes.\n * [CVE-2021-26701](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-26701>) a .NET Core Remote Code Execution (RCE) vulnerability. A remote code execution (RCE) attack happens when a threat actor illegally accesses and manipulates a computer or server without authorization from its owner. This is the only critical bug Microsoft listed as publicly known.\n * [CVE-2021-24074](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-24074>) an IPv4 security vulnerability concerning source routing behavior. Microsoft adds to say: IPv4 Source routing is considered insecure and is blocked by default in Windows; however, a system will process the request and return an ICMP message denying the request.\n * [CVE-2021-24094](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-24094>) an IPv6 security vulnerability concerning the reassembly limit and related to the previous one. The reassembly limit controls the IP fragmentation, which is an Internet Protocol (IP) process that breaks packets into smaller fragments, so that the resulting pieces can pass through a link with a smaller maximum transmission unit (MTU) than the original packet size. The fragments are reassembled by the receiving host. Apparently an attacker could construe packets leading to a situation where a large number of fragments could lead to code execution.\n * [CVE-2021-1721](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-1721>) a .NET Core and Visual Studio Denial of Service vulnerability. A Denial of Service attack is focused on making a resource (site, application, server) unavailable for the purpose it was designed.\n * [CVE-2021-1722](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-1722>) and [CVE-2021-24077](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-24077>) are both Windows Fax Service RCE problems. It's important to remember that even if you don\u2019t use \u201cWindows Fax and Scan\u201d, the Windows Fax Services is enabled by default.\n * [CVE-2021-1733](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-1733>) is for Sysinternals\u2019 PsExec Elevation of Privilege vulnerability. While this one is listed as not likely to be exploited, the tool itself is worth keeping an eye on, because it's so popular with cybercriminals. They like it because, as a legitimate administration tool, it isn't normally detected as malicious software by default.\n\nIf you are all about prioritizing your updates, these are the ones that we recommend doing first. Everyone else is advised to install the updates at their earliest convenience.\n\nOne other notable thing is the default enabling of the Domain Controller enforcement mode. This was done to counter the effects of the ZeroLogon vulnerability which is being exploited in the wild. We already covered the full story of [ZeroLogon](<https://blog.malwarebytes.com/exploits-and-vulnerabilities/2021/01/the-story-of-zerologon/>) where this change was announced.\n\n### Adobe Reader for a change\n\nAnd while you are about to start your update cycles, you may want to have a look at this one from Adobe. Because this one is already actively being exploited as well. Where Adobe was notoriously famous for the bugs in their Flash Player, which has now reached [end-of-life](<https://blog.malwarebytes.com/awareness/2021/01/adobe-flash-player-reaches-end-of-life/>), occasionally a vulnerability in their Reader attracts some attention.\n\n[CVE-2021-21017](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=2021-21017>) is a critical heap-based buffer overflow flaw. Heap is the name for a region of a process\u2019 memory which is used to store dynamic variables. A buffer overflow is a type of software vulnerability that exists when an area of memory within a software application reaches its address boundary and writes into an adjacent memory region. In software exploit code, two common areas that are targeted for overflows are the stack and the heap.\n\nSo, by creating a specially crafted input, attackers could use this vulnerability to write code into a memory location where they normally wouldn\u2019t have access. In their advisory Adobe states that it has received a report that CVE-2021-21017 has been exploited in the wild in limited attacks targeting Adobe Reader users on Windows.\n\nBoth Adobe Acrobat and Adobe Reader will automatically detect if a new version of the software is available. The program will check for a new version when you launch either Acrobat or Reader as an application and will prompt you to install a new version when it's available. IT administrators can control the update settings by using the [Adobe Customization Wizard](<https://www.adobe.com/nl/devnet-docs/acrobatetk/tools/Wizard/WizardDC/index.html>).\n\nStay safe, everyone!\n\nThe post [Big Patch Tuesday: Microsoft and Adobe fix in-the-wild exploits](<https://blog.malwarebytes.com/malwarebytes-news/2021/02/big-patch-tuesday-microsoft-and-adobe-fix-in-the-wild-exploits/>) appeared first on [Malwarebytes Labs](<https://blog.malwarebytes.com>).", "edition": 2, "cvss3": {"exploitabilityScore": 3.9, "cvssV3": {"baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "baseScore": 9.8, "privilegesRequired": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "userInteraction": "NONE", "version": "3.1"}, "impactScore": 5.9}, "published": "2021-02-10T17:26:33", "type": "malwarebytes", "title": "Big Patch Tuesday: Microsoft and Adobe fix in-the-wild exploits", "bulletinFamily": "blog", "cvss2": {"severity": "HIGH", "exploitabilityScore": 10.0, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "PARTIAL", "availabilityImpact": "PARTIAL", "integrityImpact": "PARTIAL", "baseScore": 7.5, "vectorString": "AV:N/AC:L/Au:N/C:P/I:P/A:P", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "acInsufInfo": false, "impactScore": 6.4, "obtainUserPrivilege": false}, "cvelist": ["CVE-2021-1721", "CVE-2021-1722", "CVE-2021-1732", "CVE-2021-1733", "CVE-2021-21017", "CVE-2021-24074", "CVE-2021-24077", "CVE-2021-24094", "CVE-2021-26701"], "modified": "2021-02-10T17:26:33", "id": "MALWAREBYTES:3C358DDA439A247A9677866AFE8FA961", "href": "https://blog.malwarebytes.com/malwarebytes-news/2021/02/big-patch-tuesday-microsoft-and-adobe-fix-in-the-wild-exploits/", "cvss": {"score": 6.8, "vector": "AV:N/AC:M/Au:N/C:P/I:P/A:P"}}], "threatpost": [{"lastseen": "2021-02-09T22:45:30", "description": "Microsoft has addressed nine critical-severity cybersecurity bugs in February\u2019s Patch Tuesday updates, plus an important-rated vulnerability that is being actively exploited in the wild.\n\nSix of the security holes \u2013 including one of the critical bugs \u2013 were already publicly disclosed.\n\n[](<https://threatpost.com/newsletter-sign/>)\n\nOverall, the computing giant has released patches for 56 CVEs covering Microsoft Windows components, the .NET Framework, Azure IoT, Azure Kubernetes Service, Microsoft Edge for Android, Exchange Server, Office and Office Services and Web Apps, Skype for Business and Lync, and Windows Defender.\n\n## **Actively Exploited Security Bug in Windows Kernel**\n\nThe security bug tracked as [CVE-2021-1732](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-1732>)** **is being actively exploited, according to Microsoft\u2019s advisory. It carries a vulnerability-severity rating of 7.8 on the CVSS scale, making it important in severity \u2013 however, researchers said it deserves attention above some of the critical bugs in terms of patching priority.\n\nIt exists in the Windows Win32k operating system kernel and is an elevation-of-privilege (EoP) vulnerability. It would allow a logged-on user to execute code of their choosing with higher privileges, by running a specially crafted application. If successful, attackers could execute code in the context of the kernel and gain SYSTEM privileges, essentially giving the attacker free rein to do whatever they wanted on the compromised machine.\n\n\u201cThe vulnerability affects Windows 10 and corresponding server editions of the Windows OS,\u201d said Chris Goettl, senior director of product management and security at Ivanti. \u201cThis is a prime example of why risk-based prioritization is so important. If you base your prioritization off of vendor severity and focus on \u2018critical\u2019 you could have missed this vulnerability in your prioritization. This vulnerability should put Windows 10 and Server 2016 and later editions into your priority bucket for remediation this month.\u201d\n\n## **Critical Microsoft Bugs for February Patch Tuesday**\n\nNone of the critical bugs rate more than an 8.8 (out of 10) on the CVSS scale, but all allow for remote code execution (RCE) and many should take top priority, according to security researchers.\n\n * ### Publicly Known .NET Core/Visual Studio Bug\n\nFor instance, the bug tracked as [CVE-2021-26701](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-26701>) exists in .NET Core and Visual Studio \u2013 it\u2019s the only critical-rated bug to be listed as publicly known.\n\n\u201cWithout more information from Microsoft, that\u2019s about all we know about it,\u201d said Dustin Childs, of Trend Micro\u2019s Zero Day Initiative, in [an analysis](<https://www.zerodayinitiative.com/blog/2021/2/9/the-february-2022-security-update-review>) released Tuesday. \u201cBased on the CVSS severity scale, this could allow remote, unauthenticated attackers to execute arbitrary code on an affected system. Regardless, if you rely on the .NET Framework or .NET Core, make sure you test and deploy this one quickly.\u201d\n\n * ### **Windows Fax Bugs**\n\nOther critical bugs should be on researchers\u2019 radars. The bugs tracked as [CVE-2021-1722](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-1722>) and [CVE-2021-24077](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-24077>) meanwhile are both Windows Fax Service RCE problems.\n\n\u201cWindows Fax Service specifies settings for faxes, including how they are sent, received, viewed and printed,\u201d said Eric Feldman, senior product marketing manager at Automox. \u201cThe Windows Fax Service is used by the Windows Fax and Scan application included in all versions of Microsoft Windows 7, Windows 8 and Windows 10 and some earlier versions.\u201d\n\nAn attacker who successfully exploited either vulnerability could take control of an affected system, and then be able to install programs; view, change or delete data; or create new accounts with full user rights.\n\n\u201cUsers whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights,\u201d Feldman said. \u201cEven if you do not use Windows Fax and Scan, the Windows Fax Services is enabled by default.\u201d\n\n * ### **Critical TCP/IP Bugs**\n\n[CVE-2021-24074](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-24074>) and [CVE-2021-24094](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-24094>) are both Windows TCP/IP RCE vulnerabilities. The former is found in the way Windows handles iPv4 source routing; the latter is found in the way Windows handles iPv6 packet reassembly.\n\n\u201cIPv4 source routing\u2026should be disabled by default,\u201d said Childs. \u201cYou can also block source routing at firewalls or other perimeter devices. The IPv6 bug involves packet fragmentation where a large number of fragments could lead to code execution.\u201d\n\nResearchers said that both these patches should be prioritized.\n\n\u201cBecause these affect the network stack, require zero interaction from a user and can be exploited by sending malicious network traffic to a device, it\u2019s only a matter of time before we see attackers leveraging these vulnerabilities to carry out cyberattacks,\u201d Chris Hass, director of information security and research at Automox, said.\n\nKevin Breen, director of cyber threat research at Immersive Labs, said that the IPv6 security hole is an obvious target for hackers.\n\n\u201cCVE-2021-24094 would be an obvious target because it affects a network stack, which typically operates with system level permissions and could therefore gain an attacker a system shell,\u201d he said. \u201cAs an IPV6 Link local attack it would require the threat actor to already have a foothold in your network, but could ultimately lead to a high level of access on domain controllers, for example. This vulnerability would be most dangerous to those who operate a flat network. Segmentation will help with mitigation.\u201d\n\nBreen also pointed out that RCE isn\u2019t the only possible outcome of an exploit for this bug.\n\n\u201cThe release notes indicate that the exploit is \u2018complex\u2019 \u2013 which means attempted attacks may serve to cause systems to crash, giving it the potential to be used in a denial-of-service attack,\u201d he said.\n\n * ### **Flaw in Windows Codec Pack**\n\nWindows Camera Codec Pack is home to yet another critical RCE bug ([CVE-2021-24091](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-24091>)). If successfully exploited, an attacker could run arbitrary code in the context of the current user.\n\n\u201cIf the current user is logged on with admin privileges, the attacker could gain control of the affected system,\u201d said Justin Knapp, senior product marketing manager at Automox. \u201cThis could enable an attacker to install programs; view, change, or delete data; or create new accounts with full user rights. Exploitation of the vulnerability requires the user to open a specially crafted file with an affected version of the codec pack. While there\u2019s no way to force a user to open the file, bad actors could manipulate a user through an email or web-based attack vector where the user is effectively convinced or enticed into opening the malicious file.\u201d\n\n * ### **Windows DNS Problems**\n\nAnd Windows Domain Name System (DNS) servers, when they fail to properly handle requests, are also open to a critical RCE bug ([CVE-2021-24078](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-24078>)) that could allow an attacker to run arbitrary code in the context of the Local System Account.\n\n\u201cOnly Windows servers that are configured as DNS servers are at risk of having this vulnerability exploited,\u201d Knapp said. \u201cTo exploit the vulnerability, an unauthenticated attacker could send malicious requests to the Windows DNS server. Given the low level of attack complexity and \u2018exploitation more likely\u2019 label assigned, this is a vulnerability that should be addressed immediately.\u201d\n\n * ### **Windows Print Spooler**\n\nAlso of note, _[CVE-2021-24088](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-24088>)_ affects the Windows Local Spooler, which is an important component within the Windows operating system that stores print jobs in memory until the printer is ready to accept them.\n\nIt\u2019s a bug that \u201ccould be a big concern,\u201d according to Allan Liska, senior security architect at Recorded Future.\n\n\u201cThis vulnerability impacts Windows 7 to 10 and Windows Server 2008 to 2019,\u201d he said. \u201cWindows Print Spooler vulnerabilities have been widely exploited in the wild going back to the days of Stuxnet. Just last year CVE-2020-0986 was seen by Kaspersky being [widely exploited in the wild.](<https://threatpost.com/windows-zero-day-circulating-faulty-fix/162610/>)\u201d\n\n * ### **Other Critical February 2021 Microsoft Bugs**\n\nAnd finally, .NET Core for Linux is also at risk for RCE ([CVE-2021-24112](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-24112>)); and [CVE-2021-24093](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-24093>) is a critical RCE vulnerability in the Windows graphic component. Details are scant for both, but of the latter, Breen said, \u201cThis is the kind of vulnerability built into exploit kits and triggered by low level phishing campaigns targeting users en masse.\u201d\n\nAnd, a critical bug that would allow RCE exists in the Microsoft Windows Codecs Library ([CVE-2021-24081](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-24081>)). Details are sparse, but Microsoft said that the difficulty required for exploitation is considered to be low. However, end-user interaction is required for successful exploitation.\n\n### **Publicly Disclosed Bugs of Note**\n\nOutside of the critical issues, [CVE-2021-1733](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-1733>) is a high-severity EoP vulnerability discovered to be impacting Sysinternals PsExec utility that deserves a look. It\u2019s listed as being publicly disclosed.\n\n\u201cPsExec which has been popular in the past for use in remote administration tasks such as patching remote systems, has also had a fair share of scrutiny due the utility\u2019s weaponization by criminals in malware,\u201d Nicholas Colyer, senior product marketing manager at Automox, said via email. \u201cProof-of-concept code has not been independently verified but it is notable that in January 2021, Microsoft released a patch to resolve a remote code-execution vulnerability for the same utility, indicating that it is getting attention. Robust endpoint management is necessary for any organization\u2019s continued success and it is advisable to consider alternatives in the modern era of software-as-a-service.\u201d\n\nThe other publicly reported vulnerabilities this month are [CVE-2021-1727](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-1727>), an EoP vulnerability in Windows Installer; [CVE-2021-24098](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-24098>), a DoS vulnerability in the Windows Console Driver; [CVE-2021-24106](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-24106>), an information-disclosure vulnerability in Windows DirectX; and [CVE-2021-1721](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-1721>), a .NET Core and Visual Studio DoS problem.\n\n## **Zerologon Redux**\n\nMicrosoft also again released the patch for the Netlogon vulnerability (CVE-2020-1472), which originally was resolved in August. The vulnerability has [consistently been exploited](<https://threatpost.com/microsoft-warns-zerologon-bug/160769/>) by threat actors, so the re-release serves to highlight its importance. Microsoft also starting Tuesday [began blocking by default](<https://threatpost.com/microsoft-implements-windows-zerologon-flaw-enforcement-mode/163104/>) any vulnerable connections on devices that could be used to exploit the flaw. It does this by enabling domain controller \u201cenforcement mode.\u201d\n\n\u201cWhen you consider that Zerologon led the U.S. government to issue an Emergency Directive to all federal agencies to promptly apply the patches for this vulnerability, you start to understand the gravity of the situation,\u201d Satnam Narang, staff research engineer at Tenable, told Threatpost. \u201cZerologon provides attackers a reliable way to move laterally once inside a network, giving them the ability to impersonate systems, alter passwords, and gain control over the proverbial keys to the kingdom via the domain controller itself.\u201d\n\nHe added, \u201cFor these reasons, Zerologon has been rolled into attacker playbooks, becoming a feather in the cap for post-compromise activity. We\u2019ve also seen reports of Zerologon being favored by ransomware groups like Ryuk during their campaigns.\u201d\n\n## **What Should IT Patch First?**\n\n\u201cWindows OS updates and [Adobe Acrobat and Reader](<https://threatpost.com/critical-adobe-windows-flaw/163789/>) need immediate attention with the list of exploited and publicly disclosed vulnerabilities,\u201d said Goettl.\n\nAfter that, development tools and IT tools \u201cneed some attention,\u201d he added.\n\n\u201c.Net Core and PsExec disclosures are a concern that should not go unaddressed. Because this development and IT tools do not follow the same update process as OS and application updates, it is important to review your DevOps processes and determine if you are able to detect and respond to updates for common dev components,\u201d he said. \u201cFor tools like PsExec it is important to understand your software inventory and where these tools are installed and ensure you can distribute updated versions as needed.\u201d\n\n**_Is your business an easy mark? _**_Save your spot for \u201c15 Cybersecurity Gaffes SMBs Make,\u201d **a **_**[_FREE Threatpost webinar_](<https://threatpost.com/webinars/15-cybersecurity-gaffes-and-fixes-mid-size-businesses-face/?utm_source=ART&utm_medium=ART&utm_campaign=Feb_webinar>) **_**on Feb. 24 at 2 p.m. ET.** Cybercriminals count on you making these mistakes, but our experts will help you lock down your small- to mid-sized business like it was a Fortune 100. __[Register here](<https://threatpost.com/webinars/15-cybersecurity-gaffes-and-fixes-mid-size-businesses-face/?utm_source=ART&utm_medium=ART&utm_campaign=Feb_webinar>)__ for the Wed., Feb. 24 LIVE webinar. _\n", "cvss3": {}, "published": "2021-02-09T22:33:08", "type": "threatpost", "title": "Actively Exploited Windows Kernel Bug Allows Takeover", "bulletinFamily": "info", "cvss2": {}, "cvelist": ["CVE-2020-0986", "CVE-2020-1472", "CVE-2021-1721", "CVE-2021-1722", "CVE-2021-1727", "CVE-2021-1732", "CVE-2021-1733", "CVE-2021-24074", "CVE-2021-24077", "CVE-2021-24078", "CVE-2021-24081", "CVE-2021-24088", "CVE-2021-24091", "CVE-2021-24093", "CVE-2021-24094", "CVE-2021-24098", "CVE-2021-24106", "CVE-2021-24112", "CVE-2021-26701"], "modified": "2021-02-09T22:33:08", "id": "THREATPOST:1502920D4F50B0D128077B515815C023", "href": "https://threatpost.com/exploited-windows-kernel-bug-takeover/163800/", "cvss": {"score": 9.3, "vector": "AV:N/AC:M/Au:N/C:C/I:C/A:C"}}], "rapid7blog": [{"lastseen": "2021-02-10T00:48:57", "description": "\n\nThe second Patch Tuesday of 2021 is relatively light on the vulnerability count, with 64 CVEs being addressed across the majority of Microsoft\u2019s product families. Despite that, there\u2019s still plenty to discuss this month.\n\n### Vulnerability Breakdown by Software Family\n\nFamily | Vulnerability Count \n---|--- \nWindows | 28 \nESU | 14 \nMicrosoft Office | 11 \nBrowser | 9 \nDeveloper Tools | 8 \nMicrosoft Dynamics | 2 \nExchange Server | 2 \nAzure | 2 \nSystem Center | 2 \n \n### Exploited and Publicly Disclosed Vulnerabilities\n\nOne zero-day was announced: [CVE-2021-1732](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-1732>) is a privilege elevation vulnerability affecting the Win32k component of Windows 10 and Windows Server 2019, reported to be exploited in the wild. Four vulnerabilities have been previously disclosed: [CVE-2021-1727](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-1727>), a privilege elevation vulnerability in Windows Installer, affecting all supported versions of Windows; [CVE-2021-24098](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-24098>), which is a denial of service (DoS) affecting Windows 10 and Server 2019; [CVE-2021-24106](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-24106>), an information disclosure vulnerability affecting DirectX in Windows 10 and Server 2019; and [CVE-2021-26701](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-26701>), an RCE in .NET Core.\n\n### Vulnerabilities in Windows TCP/IP\n\nMicrosoft also disclosed a set of [three serious vulnerabilities](<https://msrc-blog.microsoft.com/2021/02/09/multiple-security-updates-affecting-tcp-ip/>) affecting the TCP/IP networking stack in all supported versions of Windows. Two of these ([CVE-2021-24074](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-24074>) and [CVE-2021-24094](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-24094>)) carry a base CVSSv3 score of 9.8 and could allow Remote Code Execution (RCE). [CVE-2021-24094](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-24094>) is specific to IPv6 link-local addresses, meaning it isn\u2019t exploitable over the public internet. [CVE-2021-24074](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-24074>), however, does not have this limitation. The third, [CVE-2021-24086](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-24086>), is a DoS vulnerability that could allow an attacker to trigger a \u201cblue screen of death\u201d on any Windows system that is directly exposed to the internet, using only a small amount of network traffic. The RCE exploits are probably not a threat in the short term, due to the complexity of the vulnerabilities, but DoS attacks are expected to be seen much more quickly. Windows systems should be patched as soon as possible to protect against these.\n\nIn the event a patch cannot be applied immediately, such as on systems that cannot be rebooted, Microsoft has published mitigation guidance that will protect against exploitation of the TCP/IP vulnerabilities. Depending on the exposure of an asset, IPv4 Source Routing should be disabled via a Group Policy or a Netsh command, and IPv6 packet reassembly should be disabled via a separate Netsh command. IPv4 Source Routing requests and IPv6 fragments can also be blocked load balancers, firewalls, or other edge devices to mitigate these issues.\n\n### Zerologon Update\n\nBack in August, 2020, Microsoft addressed a critical remote code vulnerability (CVE-2020-1472) affecting the Netlogon protocol (MS-NRPC), a.k.a. \u201c[Zerologon](<https://blog.rapid7.com/2020/09/14/cve-2020-1472-zerologon-critical-privilege-escalation/>)\u201d. In October, Microsoft [noted](<https://msrc-blog.microsoft.com/2020/10/29/attacks-exploiting-netlogon-vulnerability-cve-2020-1472/>) that attacks which exploit this weakness have been seen in the wild. On January 14, 2021, they [reminded](<https://msrc-blog.microsoft.com/2021/01/14/netlogon-domain-controller-enforcement-mode-is-enabled-by-default-beginning-with-the-february-9-2021-security-update-related-to-cve-2020-1472/>) organizations that the February 2021 security update bundle will also be enabling \u201cDomain Controller enforcement mode\" by default to fully address this weakness. Any system that tries to make an insecure Netlogon connection will be denied access. Any business-critical process that relies on these insecure connections will cease to function. Rapid7 encourages all organizations to [heed the detailed guidance](<https://support.microsoft.com/en-us/topic/how-to-manage-the-changes-in-netlogon-secure-channel-connections-associated-with-cve-2020-1472-f7e8cc17-0309-1d6a-304e-5ba73cd1a11e#bkmk_detectingnon_compliant>) before applying the latest updates to ensure continued business process continuity.\n\n### Adobe\n\nMost important amongst the [six security advisories](<https://helpx.adobe.com/security.html>) published by Adobe today is [APSB21-09](<https://helpx.adobe.com/security/products/acrobat/apsb21-09.html>), detailing 23 CVEs affecting Adobe Acrobat and Reader. Six of these are rated Critical and allow Arbitrary Code Execution, and one of which (CVE-2021-21017), has been seen exploited in the wild in attacks targeting Adobe Reader users on Windows.\n\n### Summary Tables\n\n#### Azure Vulnerabilities\n\nCVE | Vulnerability Title | Exploited | Publicly Disclosed | CVSSv3 Base Score | FAQ?
