of [security updates](<https://msrc.microsoft.com/update-guide/releaseNote/2021-Jun>) for Windows operating system and other supported software, squashing 50 vulnerabilities, including six zero-days that are said to be under active attack.\n\nThe flaws were identified and resolved in Microsoft Windows, .NET Core and Visual Studio, Microsoft Office, Microsoft Edge (Chromium-based and EdgeHTML), SharePoint Server, Hyper-V, Visual Studio Code - Kubernetes Tools, Windows HTML Platform, and Windows Remote Desktop.\n\n[](<https://go.thn.li/1-728-6> \"Stack Overflow Teams\" )\n\nOf these 50 bugs, five are rated Critical, and 45 are rated Important in severity, with three of the issues publicly known at the time of release. The vulnerabilities that being actively exploited are listed below -\n\n * [**CVE-2021-33742**](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-33742>) (CVSS score: 7.5) - Windows MSHTML Platform Remote Code Execution Vulnerability\n * [**CVE-2021-33739**](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-33739>) (CVSS score: 8.4) - Microsoft DWM Core Library Elevation of Privilege Vulnerability\n * [**CVE-2021-31199**](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-31199>) (CVSS score: 5.2) - Microsoft Enhanced Cryptographic Provider Elevation of Privilege Vulnerability\n * [**CVE-2021-31201**](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-31201>) (CVSS score: 5.2) - Microsoft Enhanced Cryptographic Provider Elevation of Privilege Vulnerability\n * [**CVE-2021-31955**](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-31955>) (CVSS score: 5.5) - Windows Kernel Information Disclosure Vulnerability\n * [**CVE-2021-31956**](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-31956>) (CVSS score: 7.8) - Windows NTFS Elevation of Privilege Vulnerability\n\nMicrosoft didn't disclose the nature of the attacks, how widespread they are, or the identities of the threat actors exploiting them. But the fact that four of the six flaws are privilege escalation vulnerabilities suggests that attackers could be leveraging them as part of an infection chain to gain elevated permissions on the targeted systems to execute malicious code or leak sensitive information.\n\nThe Windows maker also noted that both CVE-2021-31201 and CVE-2021-31199 address flaws related to [CVE-2021-28550](<https://thehackernews.com/2021/05/alert-hackers-exploit-adobe-reader-0.html>), an arbitrary code execution vulnerability rectified by Adobe last month that it said was being \"exploited in the wild in limited attacks targeting Adobe Reader users on Windows.\"\n\nGoogle's Threat Analysis Group, which has been acknowledged as having reported CVE-2021-33742 to Microsoft, [said](<https://twitter.com/ShaneHuntley/status/1402320072123719690>) \"this seem[s] to be a commercial exploit company providing capability for limited nation state Eastern Europe / Middle East targeting.\"\n\nRussian cybersecurity firm Kaspersky, for its part, detailed that CVE-2021-31955 and CVE-2021-31956 were abused in a Chrome zero-day exploit chain ([CVE-2021-21224](<https://thehackernews.com/2021/04/update-your-chrome-browser-immediately.html>)) in a series of highly targeted attacks against multiple companies on April 14 and 15. The intrusions were attributed to a new threat actor dubbed \"PuzzleMaker.\"\n\n\"While we were not able to retrieve the exploit used for remote code execution (RCE) in the Chrome web browser, we were able to find and analyze an elevation of privilege (EoP) exploit that was used to escape the sandbox and obtain system privileges,\" Kaspersky Lab researchers [said](<https://securelist.com/puzzlemaker-chrome-zero-day-exploit-chain/102771/>).\n\nElsewhere, Microsoft fixed numerous remote code execution vulnerabilities spanning Paint 3D, Microsoft SharePoint Server, Microsoft Outlook, Microsoft Office Graphics, Microsoft Intune Management Extension, Microsoft Excel, and Microsoft Defender, as well as several privilege escalation flaws in Microsoft Edge, Windows Filter Manager, Windows Kernel, Windows Kernel-Mode Driver, Windows NTLM Elevation, and Windows Print Spooler.\n\n[](<https://go.thn.li/auth_728> \"Enterprise Password Management\" )\n\nTo install the latest security updates, Windows users can head to Start &gt; Settings &gt; Update &amp; Security &gt; Windows Update or by selecting Check for Windows updates.\n\n### Software Patches From Other Vendors\n\nAlongside Microsoft, a number of other vendors have also released a slew of patches on Tuesday, including \u2014\n\n * [Adobe](<https://helpx.adobe.com/security.html>)\n * [Android](<https://source.android.com/security/bulletin/2021-06-01>)\n * [Dell](<https://www.dell.com/support/security/>)\n * [Intel](<https://blogs.intel.com/technology/2021/06/intel-security-advisories-for-june-2021/>)\n * Linux distributions [SUSE](<https://lists.suse.com/pipermail/sle-security-updates/2021-June/thread.html>), [Oracle Linux](<https://linux.oracle.com/ords/f?p=105:21>), and [Red Hat](<https://access.redhat.com/security/security-updates/#/security-advisories?q=&p=2&sort=portal_publication_date%20desc&rows=10&portal_advisory_type=Security%20Advisory&documentKind=Errata>)\n * [SAP](<https://wiki.scn.sap.com/wiki/pages/viewpage.action?pageId=578125999>) (with cybersecurity firm Onapsis [credited](<https://onapsis.com/blog/sap-security-patch-day-june-2021-multiple-memory-corruption-vulnerabilities-can-lead-system>) with identifying 20 of the 40 remediated flaws)\n * [Schneider Electric](<https://www.se.com/ww/en/work/support/cybersecurity/overview.jsp>), and\n * [Siemens](<https://new.siemens.com/global/en/products/services/cert.html#SecurityPublications>)\n \n\n\nFound this article interesting?

But what this month lacks in volume it makes up for in urgency: Microsoft warns that bad guys are leveraging a half-dozen of those weaknesses to break into computers in targeted attacks.\n\nAmong the zero-days are:\n\n-[CVE-2021-33742](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-33742>), a remote code execution bug in a Windows HTML component. \n-[CVE-2021-31955](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-31955>), an information disclosure bug in the Windows Kernel \n-[CVE-2021-31956](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-31956>), an elevation of privilege flaw in Windows NTFS \n-[CVE-2021-33739](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-33739>), an elevation of privilege flaw in the Microsoft Desktop Window Manager \n-[CVE-2021-31201](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-31201>), an elevation of privilege flaw in the Microsoft Enhanced Cryptographic Provider \n-[CVE-2021-31199](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-31199>), an elevation of privilege flaw in the Microsoft Enhanced Cryptographic Provider\n\n**Kevin Breen**, director of cyber threat research at **Immersive Labs**, said elevation of privilege flaws are just as valuable to attackers as remote code execution bugs: Once the attacker has gained an initial foothold, he can move laterally across the network and uncover further ways to escalate to system or domain-level access.\n\n&quot;This can be hugely damaging in the event of ransomware attacks, where high privileges can enable the attackers to stop or destroy backups and other security tools,&quot; Breen said. &quot;The &#x27;exploit detected&#x27; tag means attackers are actively using them, so for me, it\u2019s the most important piece of information we need to prioritize the patches.&quot;\n\nMicrosoft also patched five critical bugs -- flaws that can be remotely exploited to seize control over the targeted Windows computer without any help from users. [CVE-2021-31959](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-31959>) affects everything from **Windows 7** through **Windows 10** and **Server** versions **2008**,** 2012**, **2016** and **2019**.\n\n**Sharepoint** also got a critical update in [CVE-2021-31963](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-31963>); Microsoft says this one is less likely to be exploited, but then critical Sharepoint flaws are a favorite target of ransomware criminals.\n\nInterestingly, two of the Windows zero-day flaws -- CVE-2021-31201 and CVE-2021-31199 -- are related to a patch **Adobe** released recently for [CVE-2021-28550](<https://helpx.adobe.com/security/products/acrobat/apsb21-29.html>), a flaw in **Adobe Acrobat** and **Reader** that also is being actively exploited.\n\n&quot;Attackers have been seen exploiting these vulnerabilities by sending victims specially crafted PDFs, often attached in a phishing email, that when opened on the victim&#x27;s machine, the attacker is able to gain arbitrary code execution,&quot; said** Christopher Hass**, director of information security and research at **Automox**. &quot;There are no workarounds for these vulnerabilities, patching as soon as possible is highly recommended.&quot;\n\nIn addition to updating Acrobat and Reader, Adobe patched flaws in a slew of other products today, including **Adobe Connect,** **Photoshop**, and **Creative Cloud**. The full list is [here](<https://helpx.adobe.com/security.html>), with links to updates.\n\nThe usual disclaimer:\n\nBefore you update with this month\u2019s patch batch, please make sure you have backed up your system and/or important files. It\u2019s not uncommon for Windows updates to hose one\u2019s system or prevent it from booting properly, and some updates even have been known to erase or corrupt files.\n\nSo do yourself a favor and backup _before_ installing any patches. Windows 10 even has [some built-in tools](<https://lifehacker.com/how-to-back-up-your-computer-automatically-with-windows-1762867473>) to help you do that, either on a per-file/folder basis or by making a complete and bootable copy of your hard drive all at once.\n\nAnd if you wish to ensure Windows has been set to pause updating so you can back up your files and/or system before the operating system decides to reboot and install patches on its own schedule, see [this guide](<https://www.computerworld.com/article/3543189/check-to-make-sure-you-have-windows-updates-paused.html>).\n\nAs always, if you experience glitches or problems installing any of these patches this month, please consider leaving a comment about it below; there\u2019s a better-than-even chance other readers have experienced the same and may chime in here with some helpful tips.\n\nFor a quick visual breakdown of each update released today and its severity level, check out the [this Patch Tuesday post](<https://isc.sans.edu/forums/diary/Microsoft+June+2021+Patch+Tuesday/27506/>) from the **SANS Internet Storm Center**.", "edition": 2, "cvss3": {"exploitabilityScore": 1.8, "cvssV3": {"baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "LOCAL", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "baseScore": 7.8, "privilegesRequired": "NONE", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H", "userInteraction": "REQUIRED", "version": "3.1"}, "impactScore": 5.9}, "published": "2021-06-08T20:53:28", "type": "krebs", "title": "Microsoft Patches Six Zero-Day Security Holes", "bulletinFamily": "blog", "cvss2": {"severity": "HIGH", "exploitabilityScore": 8.6, "obtainAllPrivilege": false, "userInteractionRequired": true, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "MEDIUM", "confidentialityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "baseScore": 9.3, "vectorString": "AV:N/AC:M/Au:N/C:C/I:C/A:C", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "acInsufInfo": false, "impactScore": 10.0, "obtainUserPrivilege": false}, "cvelist": ["CVE-2021-28550", "CVE-2021-31199", "CVE-2021-31201", "CVE-2021-31955", "CVE-2021-31956", "CVE-2021-31959", "CVE-2021-31963", "CVE-2021-33739", "CVE-2021-33742"], "modified": "2021-06-08T20:53:28", "id": "KREBS:E374075CAB55D7AB06EBD73CB87D33CD", "href": "https://krebsonsecurity.com/2021/06/microsoft-patches-six-zero-day-security-holes/", "cvss": {"score": 9.3, "vector": "AV:N/AC:M/Au:N/C:C/I:C/A:C"}}], "threatpost": [{"lastseen": "2021-06-08T22:18:00", "bulletinFamily": "info", "cvelist": ["CVE-2021-21224", "CVE-2021-28550", "CVE-2021-31199", "CVE-2021-31201", "CVE-2021-31955", "CVE-2021-31956", "CVE-2021-31963", "CVE-2021-31968", "CVE-2021-31985", "CVE-2021-33739", "CVE-2021-33742"], "description": "Microsoft jumped on 50 vulnerabilities in this month\u2019s [Patch Tuesday update](<https://msrc.microsoft.com/update-guide>), issuing fixes for CVEs in Microsoft Windows, .NET Core and Visual Studio, Microsoft Office, Microsoft Edge (Chromium-based and EdgeHTML), SharePoint Server, Hyper-V, Visual Studio Code \u2013 Kubernetes Tools, Windows HTML Platform, and Windows Remote Desktop.\n\nFive of the CVEs are rated Critical and 45 are rated Important in severity.

Rating: Important. CVSS 5.2\n\n## CVE-2021-33742\n\nThis RCE vulnerability exploits MSHTML, a component used by the Internet Explorer engine to read and display content from websites.The bug could allow an attacker to execute code on a target system if a user views specially crafted web content. The [Zero Day Initiative](<https://www.zerodayinitiative.com/blog/2021/6/8/the-june-2021-security-update-review>)\u2018s (ZDI\u2019s) Dustin Childs noted in his Patch Tuesday analysis that since the vulnerability is in the Trident (MSHTML) engine itself, many different applications are affected, not just Internet Explorer. \u201cIt\u2019s not clear how widespread the active attacks are, but considering the vulnerability impacts all supported Windows versions, this should be at the top of your test and deploy list,\u201d he recommended.\n\nThe vulnerability doesn\u2019t require special privilege to exploit, though the attack complexity is high, if that\u2019s any consolation. An attacker would need to do some extra legwork to pull it off, noted Satnam Narang, staff research engineer at Tenable, in an email to Threatpost on Tuesday.\n\nImmersive Labs\u2019 Kevin Breen, director of cyber threat research, noted that visiting a website in a vulnerable browser is \u201ca simple way for attackers to deliver this exploit.\u201d He told Threatpost via email on Tuesday that since the library is used by other services and applications, \u201cemailing HTML files as part of a phishing campaign is also a viable method of delivery.\u201d\n\n[Sophos decreed](<https://news.sophos.com/en-us/2021/06/08/six-in-the-wild-exploits-patched-in-microsofts-june-security-fix-release/>) this one to be the top concern of this month\u2019s crop, given that it\u2019s already being actively exploited by malicious actors.\n\n## CVE-2021-31955, CVE-2021-31956: Used in PuzzleMaker Targeted Malware\n\nCVE-2021-31955 is an information disclosure vulnerability in the Windows Kernel, while CVE-2021-31956 is an elevation of privilege vulnerability in Windows NTFS. The ZDI\u2019s Childs noted that CVE-2021-31956 was reported by the same researcher who found CVE-2021-31955, an information disclosure bug also listed as under active attack. They could be linked, he suggested: \u201cIt\u2019s possible these bugs were used in conjunction, as that is a common technique \u2013 use a memory leak to get the address needed to escalate privileges. These bugs are important on their own and could be even worse when combined. Definitely prioritize the testing and deployment of these patches.\u201d\n\nHe was spot-on. On Tuesday, Kaspersky announced that its researchers had discovered a highly targeted malware campaign launched in April against multiple companies, in which a previously unknown threat actor used a chain of Chrome and Windows zero-day exploits: Namely, these two.\n\nIn a press release, Kaspersky said that one of the exploits was used for RCE in the Google Chrome web browser, while the other was an elevation of privilege exploit fine-tuned to target \u201cthe latest and most prominent builds\u201d of Windows 10.\n\n\u201cRecent months have seen a wave of advanced threat activity exploiting zero-days in the wild,\u201d according to the release. \u201cIn mid-April, Kaspersky experts discovered yet a new series of highly targeted exploit attacks against multiple companies that allowed the attackers to stealthily compromise the targeted networks.\u201d\n\nKaspersky hasn\u2019t yet found a connection between these attacks and any known threat actors, so it\u2019s gone ahead and dubbed the actor PuzzleMaker. It said that all the attacks were conducted through Chrome and used an exploit that allowed for RCE. Kaspersky researchers weren\u2019t able to retrieve the code for the exploit, but the timeline and availability suggests the attackers were using the now-patched [CVE-2021-21224](<https://www.cvedetails.com/cve/CVE-2021-21224>) vulnerability in Chrome and Chromium browsers that allows attackers to exploit the Chrome renderer process (the processes that are responsible for what happens inside users\u2019 tabs).\n\nKaspersky experts did find and analyze the second exploit, however: An elevation of privilege exploit that exploits two distinct vulnerabilities in the Microsoft Windows OS kernel: CVE-2021-31955 and CVE-2021-31956. The CVE-2021-31955 bug \u201cis affiliated with SuperFetch, a feature first introduced in Windows Vista that aims to reduce software loading times by pre-loading commonly used applications into memory,\u201d they explained.\n\nThe second flaw, CVE-2021-31956, is an Elevation of Privilege vulnerability and heap-based buffer overflow. Kaspersky said that attackers used this vulnerability alongside Windows Notification Facility (WNF) \u201cto create arbitrary memory read/write primitives and execute malware modules with system privileges.\u201d\n\n\u201cOnce the attackers have used both the Chrome and Windows exploits to gain a foothold in the targeted system, the stager module downloads and executes a more complex malware dropper from a remote server,\u201d they continued. \u201cThis dropper then installs two executables, which pretend to be legitimate files belonging to Microsoft Windows OS. The second of these two executables is a remote shell module, which is able to download and upload files, create processes, sleep for certain periods of time, and delete itself from the infected system.\u201d\n\nBoris Larin, senior security researcher with Kaspersky\u2019s Global Research and Analysis Team (GReAT), said that the team hasn\u2019t been able to link these highly targeted attacks to any known threat actor: Hence the name PuzzleMaker and the determination to closely monitor the security landscape \u201cfor future activity or new insights about this group,\u201d he was quoted as saying in the press release.\n\nIf the current trend is any indication, expect to see more of the same, Larin said. \u201cOverall, of late, we\u2019ve been seeing several waves of high-profile threat activity being driven by zero-day exploits,\u201d he said. \u201cIt\u2019s a reminder that zero days continue to be the most effective method for infecting targets. Now that these vulnerabilities have been made publicly known, it\u2019s possible that we\u2019ll see an increase of their usage in attacks by this and other threat actors. That means it\u2019s very important for users to download the latest patch from Microsoft as soon as possible.\u201d\n\n## CVE-2021-31199/CVE-2021-31201\n\nThe two Enhanced Cryptographic Provider Elevation of Privilege vulnerabilities are linked to the Adobe Reader bug that [came under active attack](<https://threatpost.com/adobe-zero-day-bug-acrobat-reader/166044/>) last month (CVE-2021-28550), ZDI explained. \u201cIt\u2019s common to see privilege escalation paired with code execution bugs, and it seems these two vulnerabilities were the privilege escalation part of those exploits,\u201d he explained. \u201cIt is a bit unusual to see a delay between patch availability between the different parts of an active attack, but good to see these holes now getting closed.\u201d\n\n## CVE-2021-33739\n\nBreen noted that privilege escalation vulnerabilities such as this one in the Microsoft DWM Core Library are just as valuable to attackers as RCEs. \u201cOnce they have gained an initial foothold, they can move laterally across the network and uncover further ways to escalate to system or domain-level access,\u201d he said. \u201cThis can be hugely damaging in the event of ransomware attacks, where high privileges can enable the attackers to stop or destroy backups and other security tools.\u201d\n\n**Download our exclusive FREE Threatpost Insider eBook, ****_\u201c_**[**_2021: The Evolution of Ransomware_**](<https://threatpost.com/ebooks/2021-the-evolution-of-ransomware/?utm_source=April_eBook&utm_medium=ART&utm_campaign=ART>)**_,\u201d_**** to help hone your cyber-defense strategies against this growing scourge.

The Windows updates alone included seven zero-day vulnerability updates, two of them are actively being used in the wild by a group called PuzzleMaker, four others that have also been seen in the wild, plus one other zero-day vulnerability not known to have been actively exploited. Add to that 45 vulnerabilities that were labelled important, and security updates for Android, Adobe, SAP, and Cisco. You can practically see the IT staff scrambling to figure out what to do first and what needs to be checked before applying the patches.\n\n### PuzzleMaker\n\nSecurity researchers have discovered a new threat actor dubbed [PuzzleMaker](<https://securelist.com/puzzlemaker-chrome-zero-day-exploit-chain/102771/>), that was found using a chain of Google Chrome and Windows 10 zero-day exploits in highly targeted attacks against multiple companies worldwide. Unfortunately the researchers were unable to conclusively identify the Chrome vulnerability that was used (but they do have a suspect). The good news is that the two Windows vulnerabilities in the attack chain were included in the Windows 10 KB5003637 &amp; KB5003635 cumulative updates. These vulnerabilities are listed as [CVE-2021-31955](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-31955>), a Windows kernel information disclosure vulnerability, and [CVE-2021-31956](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-31956>), a Windows NTFS elevation of privilege vulnerability.\n\n### Other critical issues\n\nThe other critical patches made available by Microsoft this June include these actively exploited vulnerabilities:\n\n * [CVE-2021-33739](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-33739>), a Microsoft DWM Core Library Elevation of Privilege Vulnerability.\n * [CVE-2021-33742](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-33742>) Windows MSHTML Platform Remote Code Execution Vulnerability.\n * [CVE-2021-31199](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-31199>) Microsoft Enhanced Cryptographic Provider Elevation of Privilege Vulnerability.\n * [CVE-2021-31201](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-31201>) another Microsoft Enhanced Cryptographic Provider Elevation of Privilege Vulnerability.\n\nNot (yet) actively exploited zero day vulnerability:\n\n * [CVE-2021-31968](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-31968>) Windows Remote Desktop Services Denial of Service Vulnerability.\n\nOther critical updates:\n\n * [CVE-2021-31963](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-31963>) Microsoft SharePoint Server Remote Code Execution Vulnerability.\n * [CVE-2021-31959](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-31959>) Scripting Engine Memory Corruption Vulnerability.\n * [CVE-2021-31967](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-31967>) VP9 Video Extensions Remote Code Execution Vulnerability.\n * [CVE-2021-31985](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-31985>) Microsoft Defender Remote Code Execution Vulnerability.\n * [CVE-2021-33742](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-33742>) Windows MSHTML Platform Remote Code Execution Vulnerability.\n\n### Android\n\nThe [Android Security Bulletin of June 7](<https://source.android.com/security/bulletin/2021-06-01>) mentions a critical security vulnerability in the System component that &quot;could enable a remote attacker using a specially crafted transmission to execute arbitrary code within the context of a privileged process&quot;, which is as bad as it sounds. That vulnerability, listed as [CVE-2021-0507](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=2021-0507>), could allow an attacker to take control of a targeted Android device unless it&#x27;s patched.\n\n### Cisco\n\nCisco has issued a [patch](<https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-ssl-decrypt-dos-DdyLuK6c>) for a vulnerability in the software-based SSL/TLS message handler of Cisco Firepower Threat Defense (FTD) Software, that could allow an unauthenticated, remote attacker to trigger a reload of an affected device, resulting in a denial of service (DoS) condition. An attacker could exploit this vulnerability by sending a crafted SSL/TLS message **through** an affected device. SSL/TLS messages sent **to** an affected device do not trigger this vulnerability. Cisco informs us that there is no workaround for this issue. Patching is the only solution.\n\n### SAP\n\nIn the SAP advisory for [Security Patch Day \u2013 June 2021](<https://wiki.scn.sap.com/wiki/pages/viewpage.action?pageId=578125999>) we can find two issues that are labelled as \u201cHot News\u201d:\n\n * [CVE-2021-276](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-27602>)[0](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-27602>)[2](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-27602>) SAP Commerce, versions - 1808, 1811, 1905, 2005, 2011, Backoffice application allows certain authorized users to create source rules which are translated to drools rule when published to certain modules within the application. An attacker with this authorization can inject malicious code in the source rules and perform remote code execution enabling them to compromise the confidentiality, integrity and availability of the application.\n * [CVE-2021-27610](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-27610>) Improper Authentication in SAP NetWeaver ABAP Server and ABAP Platform.\n\n### Adobe\n\nTo top things off, Adobe has released a giant [Patch ](<https://helpx.adobe.com/security.html>)[Tuesday security update](<https://helpx.adobe.com/security.html>) release that fixes vulnerabilities in ten applications, including Adobe Acrobat (of course), Reader, and Photoshop. Notably five vulnerabilities in Adobe Acrobat and Reader were fixed that address multiple critical vulnerabilities. Acrobat&#x27;s determination to cement its place as [the new Flash](<https://blog.malwarebytes.com/awareness/2021/01/adobe-flash-player-reaches-end-of-life/>) shows no sign of dimming.\n\nSuccessful exploitation could lead to arbitrary code execution in the context of the current user on both Windows and macOS. The same is true for two critical vulnerabilities in Photoshop that could lead to arbitrary code execution in the context of the current user.\n\n### CVE\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). Which is why we try and link you to the Mitre list of CVE\u2019s where possible. It allows interested parties to find and compare vulnerabilities.\n\nHappy patching, everyone!\n\nThe post [Microsoft fixes seven zero-days, including two PuzzleMaker targets, Google fixes serious Android flaw](<https://blog.malwarebytes.com/exploits-and-vulnerabilities/2021/06/microsoft-fixes-seven-zero-days-including-two-puzzlemaker-targets-google-fixes-serious-android-flaw/>) appeared first on [Malwarebytes Labs](<https://blog.malwarebytes.com>).", "edition": 2, "cvss3": {"exploitabilityScore": 1.8, "cvssV3": {"baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "LOCAL", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "baseScore": 7.8, "privilegesRequired": "NONE", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H", "userInteraction": "REQUIRED", "version": "3.1"}, "impactScore": 5.9}, "published": "2021-06-09T14:50:52", "type": "malwarebytes", "title": "Microsoft fixes seven zero-days, including two PuzzleMaker targets, Google fixes serious Android flaw", "bulletinFamily": "blog", "cvss2": {"severity": "HIGH", "exploitabilityScore": 8.6, "obtainAllPrivilege": false, "userInteractionRequired": true, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "MEDIUM", "confidentialityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "baseScore": 9.3, "vectorString": "AV:N/AC:M/Au:N/C:C/I:C/A:C", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "acInsufInfo": false, "impactScore": 10.0, "obtainUserPrivilege": false}, "cvelist": ["CVE-2021-0507", "CVE-2021-27602", "CVE-2021-27610", "CVE-2021-31199", "CVE-2021-31201", "CVE-2021-31955", "CVE-2021-31956", "CVE-2021-31959", "CVE-2021-31963", "CVE-2021-31967", "CVE-2021-31968", "CVE-2021-31985", "CVE-2021-33739", "CVE-2021-33742"], "modified": "2021-06-09T14:50:52", "id": "MALWAREBYTES:84CB84E43C5F560FDE9B8B7E65F7C4A3", "href": "https://blog.malwarebytes.com/exploits-and-vulnerabilities/2021/06/microsoft-fixes-seven-zero-days-including-two-puzzlemaker-targets-google-fixes-serious-android-flaw/", "cvss": {"score": 9.3, "vector": "AV:N/AC:M/Au:N/C:C/I:C/A:C"}}], "avleonov": [{"lastseen": "2021-07-28T14:34:07", "description": "Hello everyone! Let&#x27;s now talk about Microsoft Patch Tuesday vulnerabilities for the second quarter of 2021. April, May and June. Not the most exciting topic, I agree. I am surprised that someone is reading or watching this. For me personally, this is a kind of tradition. Plus this is an opportunity to try Vulristics in action and find possible problems. It is also interesting to see what VM vendors considered critical back then and what actually became critical. I will try to keep this video short.\n\nFirst of all, let&#x27;s take a look at the vulnerabilities from the April Patch Tuesday. 108 vulnerabilities, 55 of them are RCEs. Half of these RCEs (27) are weird RPC vulnerabilities. &quot;Researcher who reported these bugs certainly found quite the attack surface&quot;. The most critical vulnerability is RCE in Exchange (CVE-2021-28480). This is not ProxyLogon, this is another vulnerability. ProxyLogon was in March. And this vulnerability is simply related to ProxyLogon, so it is believed that it is exploited in the wild as well. In the second place this Win32k Elevation of Privilege (CVE-2021-28310). It is clearly mentioned in several sources as being used in real attacks. &quot;Bugs of this nature are typically combined with other bugs, such as a browser bug or PDF exploit, to take over a system&quot;. And the only vulnerability with a public exploit is the Azure DevOps Server Spoofing (CVE-2021-28459). Previously known as Team Foundation Server (\u200bTFS), Azure DevOps Server is a set of collaborative software development tools. It is hosted on-premises. Therefore, this vulnerability can be useful for attackers.\n\nLet&#x27;s take a look at May. A very small Patch Tuesday. There are only 55 vulnerabilities. Vendors mainly wrote about HTTP Protocol Stack Remote Code Execution Vulnerability. But no catastrophe happened. &quot;tenable: On May 16, security researcher 0vercl0k published PoC code to github for CVE-2021-31166. Based on our analysis, this exploit could only result in a denial of service (DoS) condition&quot;. VM vendors also wrote a lot about Hyper-V Remote Code Execution Vulnerability. But there was no real exploitation there either. But a real exploit appeared for Remote Code Execution in Microsoft SharePoint (CVE-2021-31181). And exploitation in the wild was mentioned for Windows Container Manager Service (CVE-2021-31167), which no VM vendor mentioned at all. But the exploitation was &quot;Personally observed in an environment&quot;, so this may not be accurate. Also take a look at Memory Corruption in Microsoft Scripting Engine (CVE-2021-26419) with a public exploit and Information Disclosure in Windows Wireless Networking (CVE-2020-24587) with a sign of exploitation in the wild (but this also may not be accurate).\n\nAnd finally June. There are even fewer vulnerabilities, only 49. But there are a lot of them with a sign of exploitation in the wild. And this information is directly from Microsoft. Windows MSHTML Platform Remote Code Execution (CVE-2021-33742). Elevations of Privilege in Windows NTFS (CVE-2021-31956), Microsoft Enhanced Cryptographic Provider (CVE-2021-31199, CVE-2021-31201), Microsoft DWM Core Library (CVE-2021-33739). Windows Kernel Information Disclosure (CVE-2021-31955). Much more than usual. VM vendors have written the most about EoP in Windows NTFS (CVE-2021-31956). Do you know what vulnerability they didn&#x27;t highlight at all? Elevations of Privilege and later Remote Code Execution in Windows Print Spooler (CVE-2021-1675). The one that started the PrintNightmare story. Very ironic. Also pay attention to Spoofing in Microsoft SharePoint (CVE-2021-31950) for which there is a public Server-Side Request Forgery exploit. VM vendors also did not write anything about this vulnerability in their reviews.\n\nFull Vulristics reports:\n\n * [ms_patch_tuesday_april2021_report_avleonov_comments.html](<https://avleonov.com/vulristics_reports/ms_patch_tuesday_april2021_report_avleonov_comments.html>)\n * [ms_patch_tuesday_may2021_report_avleonov_comments.html](<https://avleonov.com/vulristics_reports/ms_patch_tuesday_may2021_report_avleonov_comments.html>)\n * [ms_patch_tuesday_june2021_report_avleonov_comments.html](<https://avleonov.com/vulristics_reports/ms_patch_tuesday_june2021_report_avleonov_comments.html>)\n\n", "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": "2021-07-10T00:14:59", "type": "avleonov", "title": "Vulristics: Microsoft Patch Tuesdays Q2 2021", "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"}, "acInsufInfo": false, "impactScore": 10.0, "obtainUserPrivilege": false}, "cvelist": ["CVE-2020-24587", "CVE-2021-1675", "CVE-2021-26419", "CVE-2021-28310", "CVE-2021-28459", "CVE-2021-28480", "CVE-2021-31166", "CVE-2021-31167", "CVE-2021-31181", "CVE-2021-31199", "CVE-2021-31201", "CVE-2021-31950", "CVE-2021-31955", "CVE-2021-31956", "CVE-2021-33739", "CVE-2021-33742"], "modified": "2021-07-10T00:14:59", "id": "AVLEONOV:9D3D76F4CC74C7ABB8000BC6AFB2A2CE", "href": "http://feedproxy.google.com/~r/avleonov/~3/zKo35MmSBcA/", "cvss": {"score": 10.0, "vector": "AV:N/AC:L/Au:N/C:C/I:C/A:C"}}], "rapid7blog": [{"lastseen": "2021-06-15T09:07:00", "bulletinFamily": "info", "cvelist": ["CVE-2021-1675", "CVE-2021-26414", "CVE-2021-26420", "CVE-2021-31199", "CVE-2021-31201", "CVE-2021-31938", "CVE-2021-31939", "CVE-2021-31940", "CVE-2021-31941", "CVE-2021-31942", "CVE-2021-31943", "CVE-2021-31944", "CVE-2021-31945", "CVE-2021-31946", "CVE-2021-31948", "CVE-2021-31949", "CVE-2021-31950", "CVE-2021-31951", "CVE-2021-31952", "CVE-2021-31953", "CVE-2021-31954", "CVE-2021-31955", "CVE-2021-31956", "CVE-2021-31957", "CVE-2021-31958", "CVE-2021-31959", "CVE-2021-31960", "CVE-2021-31962", "CVE-2021-31963", "CVE-2021-31964", "CVE-2021-31965", "CVE-2021-31966", "CVE-2021-31967", "CVE-2021-31968", "CVE-2021-31969", "CVE-2021-31970", "CVE-2021-31971", "CVE-2021-31972", "CVE-2021-31973", "CVE-2021-31974", "CVE-2021-31975", "CVE-2021-31976", "CVE-2021-31977", "CVE-2021-31978", "CVE-2021-31980", "CVE-2021-31983", "CVE-2021-31985", "CVE-2021-33739", "CVE-2021-33741", "CVE-2021-33742"], "description": "\n\nIt is another low volume Patch Tuesday this month as Microsoft releases fixes for 50 vulnerabilities. This should not diminish the importance of speedily applying the updates. 6 of the vulnerabilities being patched this month are 0-days under active exploitation ([CVE-2021-31955](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-31955>), [CVE-2021-31956](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-31956>), [CVE-2021-33739](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-33739>), [CVE-2021-33742](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-33742>), [CVE-2021-31199](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-31199>), and [CVE-2021-31201](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-31201>)). These patches should be given immediate priority. Luckily they can all be addressed by normal operating system patches and should not require additional manual intervention. Additionally, Enterprises should take action on [CVE-2021-31962](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-31962>) if they use Kerberos in their environment as it may allow an attacker to bypass Kerberos authentication altogether.\n\n## Windows MSHTML Platform Remote Code Execution Vulnerability ([CVE-2021-33742](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-33742>))\n\nThis is the only 0-day vulnerability this month which results in a remote code execution. The vulnerability lies within the MSHTML platform which is used by Internet Explorer 11 and Edge Legacy. While these two products are no longer fully supported (Edge Legacy is end of life and IE 11 is no longer supported on certain platforms) the underlying HTML libraries continue to be updated as other applications can make use of it. Further details for this vulnerability will be published by Google's Threat Analysis Group within the next 30 days.\n\n## Kerberos AppContainer Security Feature Bypass Vulnerability ([CVE-2021-31962](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-31962>))\n\nWhile this vulnerability has not been exploited in the wild yet, it would be a rather juicy target for exploit developers. Were this to be exploited it may allow a complete bypass of Kerberos authentication, allowing a connection without a password. Kerberos is generally used in Enterprise environments and as such sysadmins should patch this if they are leveraging the strong cryptography authentication mechanism.\n\n## Multiple Elevation of Privilege 0-days \n\n### [CVE-2021-31955](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-31955>), [CVE-2021-31956](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-31956>), [CVE-2021-33739](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-33739>), [CVE-2021-31199](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-31199>), and [CVE-2021-31201](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-31201>)\n\n \nThe rest of the 0-days this month can result in elevation of privilege. These vulnerabilities are often chained with other vulnerabilities in order to achieve code execution as an Administrator. Luckily for defenders, these vulnerabilities are simply patched using the traditional update methods.\n\n## Summary Tables\n\nHere are this month's patched vulnerabilities split by the product
