Hot off the press, it’s another issue of the Patch Tuesday blog! While the number of vulnerabilities is low this month, there are a number of high risk items administrators will want to patch right away including a few that will require additional remediation steps. This Patch Tuesday also includes updates for three vulnerabilities that were publicly disclosed earlier this month. Let’s jump in.
## Windows Elevation of Privilege Vulnerability aka HiveNightmare/SeriousSAM
<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-36934>
With a public proof-of-concept having been available for some time, administrators should prioritize taking action on CVE-2021-36934. Remediation for this vulnerability requires volume shadow copies for system files to be deleted. This is due to the nature of the vulnerability, as the files with the vulnerable permissions could be restored from a backup and accessed even after the patch is installed. Microsoft indicates they took caution not to delete users' backups, but the trade-off is that customers will need to do the chore themselves. We've updated [our blog post](<https://www.rapid7.com/blog/post/2021/07/21/microsoft-sam-file-readability-cve-2021-36934-what-you-need-to-know/>) with this additional information.
## Windows LSA Spoofing Vulnerability aka ADV210003
<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-36942>
Another high priority action for patching teams is CVE-2021-36942. This update patches one of the vectors used in the PetitPotam attack. After applying this update there are additional configurations required in order to protect systems from other attack vectors using registry keys. The InsightVM team has included detection for the registry keys needed to enable EPA and SMB Signing in addition to the normal update. Please see [our blog post](<https://www.rapid7.com/blog/post/2021/08/03/petitpotam-novel-attack-chain-can-fully-compromise-windows-domains-running-ad-cs/>) for more information.
## Windows Services for NFS ONCRPC XDR Driver Remote Code Execution Vulnerability
<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-26432>
While Microsoft has not offered up any details for this vulnerability we can glean some info from the CVSS information. This remote code execution vulnerability is reachable from the network service with no authentication or user action required. There may not be an exploit available for this yet, but Microsoft indicates that “Exploitation [is] more likely”. Put this update near the top of your TODO list.
## Windows TCP/IP Remote Code Execution Vulnerability
<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-26424>
Last on our list is a vulnerability that can result in remote execution on a Hyper-V host via the IPv6 networking stack. If Hyper-V is used in your environment this should be first on your list this month.

Yet another news episode.\n\n## Microsoft's August Patch Tuesday\n\nLet's start with Microsoft's August Patch Tuesday. I think the most interesting thing is that it contains a fix for the PetitPotam vulnerability. I talked about this vulnerability two weeks ago. At the time, Microsoft had no plans to release a patch because PetitPotam was a "classic NTLM Relay Attack". But the patch was actually released as part of August Patch Tuesday.\n\nA [quote from Rapid7](<https://www.rapid7.com/blog/post/2021/08/03/petitpotam-novel-attack-chain-can-fully-compromise-windows-domains-running-ad-cs/>): _"Tracked as CVE-2021-36942, the August 2021 Patch Tuesday security update blocks the affected API calls OpenEncryptedFileRawA and OpenEncryptedFileRawW through the LSARPC interface"_. \n\nThere are no formal signs that this vulnerability is critical other than comments from the vendors. My Vulristics tool has flagged this "Windows LSA Spoofing" as a Medium level Vulnerability. But this fix seems to be the most important thing in this Patch Tuesday. So install this patch first.\n\nSpeaking of other vulnerabilities. There was nothing critical. No vulnerabilities with public exploits. Only one vulnerability that has been exploited in the wild, CVE-2021-36948 \u2013 Windows Update Medic Service Elevation of Privilege. But this is EoP and there are no public exploits yet, so I think you can patch it as planned without hurry.\n\nSeveral potentially dangerous RCEs:\n\n * Windows Print Spooler (CVE-2021-36936, CVE-2021-36947). They look similar to PrintNightmare, but there are no details yet.\n * Windows TCP/IP (CVE-2021-26424) and Remote Desktop Client (CVE-2021-34535). Such vulnerabilities rarely get public exploits.\n * NFS ONCRPC XDR Driver (CVE-2021-26432). Nothing is clear at all.\n\nIn general, it looks like a ptetty calm Patch Tuesday. If you're interested, a link to the Vulristics report: In general, it looks like a ptetty calm Patch Tuesday. If you're interested, a link to the Vulristics report: [ms_patch_tuesday_august2021](<https://avleonov.com/vulristics_reports/ms_patch_tuesday_august2021_report_avleonov_comments.html>)\n\n## Phishers started using reCAPTCHA\n\nFunny news that I really liked. [Phishers started using reCAPTCHA](<https://threatpost.com/cyberattackers-captchas-phishing-malware/168684/>) to bypass the automatic detection of phishing sites. The script only sees the safe page with a CAPTCHA and can't solve it. But a real person just solves it without thinking, because people used to seeing and solving such CAPTCHAs, and see the complete phishing site. It's very simple and ingenious! \n\n## Scan one IP and go to the prison\n\nAnd the last will be [a local news from Russia](<https://www.rbc.ru/technology_and_media/17/08/2021/611a95059a7947e9bf954a8f>). But the case is interesting. One guy worked in the tech support of some internet provider. And he decided to scan the network of this provider, detect misconfigured routers of the clients and inform them about the found vulnerabilities. His boss knew about it. Unfortunatelly, these clients included some government scientific research-to-production facility with a mail server available on the scanned IP. This facility is a \u201ccritical infrastructure\u201d object and the actions of a support technician are classified as an attack on critical infrastructure. He can spend up to 7 years in prison. Why he personally and not his employer? That guy worked remotelly from home and scanned from his personal IP address.\n\nA pretty crazy story, but it shows the cirumstances of "penetration testing" or "bughunting" without getting all necessery formal permissions. It also shows how, in theory, a person could be easily framed as an attacker if that person's personal device is compromised. Also, I don't think port scanning or banner grabbing is actually an attack, IMHO this is normal network activity. And I don't think that checking the default passwords is always an attack, but it is a topic for discussion. In fact it doesn't matter what I or we think, it's only law enforcement practice that matters, and that practice can be pretty harsh. So keep that in mind and don't scan the unknown hosts that don't belong to you unless you want sudden problems.", "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": "2021-08-19T21:38:46", "type": "avleonov", "title": "Security News: Microsoft Patch Tuesday August 2021, Phishers Started Using reCAPTCHA, Scan 1 IP and Go to Jail", "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-2021-26424", "CVE-2021-26432", "CVE-2021-34535", "CVE-2021-36936", "CVE-2021-36942", "CVE-2021-36947", "CVE-2021-36948"], "modified": "2021-08-19T21:38:46", "id": "AVLEONOV:3530747E605445686B7211B2B0853579", "href": "https://avleonov.com/2021/08/20/security-news-microsoft-patch-tuesday-august-2021-phishers-started-using-recaptcha-scan-1-ip-and-go-to-jail/", "cvss": {"score": 7.5, "vector": "AV:N/AC:L/Au:N/C:P/I:P/A:P"}}], "chrome": [{"lastseen": "2021-12-30T22:31:13", "description": "The Stable channel has been updated to 92.0.4515.131 for Windows, Mac and Linux which will roll out over the coming days/weeks\n\n\nA full list of changes in this build is available in the [log](<https://chromium.googlesource.com/chromium/src/+log/92.0.4515.107..92.0.4515.131?pretty=fuller&n=10000>).

We have also seen a similar reduction in critical vulnerabilities this month, with 30 percent less compared to the monthly average.\u201d\n\n## **Windows Critical Security Vulnerabilities**\n\nThe seven critical bugs [addressed in August](<https://msrc.microsoft.com/update-guide/>) are as follows:\n\n * CVE-2021-26424 \u2013 Windows TCP/IP RCE Vulnerability\n * CVE-2021-26432 \u2013 Windows Services for NFS ONCRPC XDR Driver RCE Vulnerability\n * CVE-2021-34480 \u2013 Scripting Engine Memory Corruption Vulnerability\n * CVE-2021-34530 \u2013 Windows Graphics Component RCE Vulnerability\n * CVE-2021-34534 \u2013 Windows MSHTML Platform RCE Vulnerability\n * CVE-2021-34535 \u2013 Remote Desktop Client RCE Vulnerability\n * CVE-2021-36936 \u2013 Windows Print Spooler RCE Vulnerability\n\nThe bug tracked as **CVE-2021-26424** exists in the TCP/IP protocol stack identified in Windows 7 and newer Microsoft operating systems, including servers.\n\n\u201cDespite its CVSS rating of 9.9, this may prove to be a trivial bug, but it\u2019s still fascinating,\u201d said Dustin Childs of Trend Micro\u2019s Zero Day Initiative (ZDI) in his [Tuesday analysis](<https://www.zerodayinitiative.com/blog/2021/8/10/the-august-2021-security-update-review>). \u201cAn attacker on a guest Hyper-V OS could execute code on the host Hyper-V server by sending a specially crafted IPv6 ping. This keeps it out of the wormable category. Still, a successful attack would allow the guest OS to completely take over the Hyper-V host. While not wormable, it\u2019s still cool to see new bugs in new scenarios being found in protocols that have been around for years.\u201d\n\nThe next bug, **CVE-2021-26432** in Windows Services, is more likely to be exploited given its low complexity status, according to Microsoft\u2019s advisory; it doesn\u2019t require privileges or user interaction to exploit, but Microsoft offered no further details.\n\n\u201cThis may fall into the \u2018wormable\u2019 category, at least between servers with NFS installed, especially since the open network computing remote procedure call (ONCRPC) consists of an External Data Representation (XDR) runtime built on the Winsock Kernel (WSK) interface,\u201d Childs said. \u201cThat certainly sounds like elevated code on a listening network service. Don\u2019t ignore this patch.\u201d\n\nAleks Haugom, product marketing manager at Automox, added, \u201cExploitation results in total loss of confidentiality across all devices managed by the same security authority. Furthermore, attackers can utilize it for denial-of-service attacks or to maliciously modify files. So far, no further details have been divulged by Microsoft or the security researcher (Liubenjin from Codesafe Team of Legendsec at Qi\u2019anxin Group) that discovered this vulnerability. Given the broad potential impact, its label \u2018Exploitation More Likely\u2019 and apparent secrecy, patching should be completed ASAP.\u201d\n\nMeanwhile, the memory-corruption bug (**CVE-2021-34480**) arises from how the scripting engine handles objects in memory, and it also allows RCE. Using a web-based attack or a malicious file, such as a malicious landing page or phishing email, attackers can use this vulnerability to take control of an affected system, install programs, view or change data, or create new user accounts with full user rights.\n\n\u201cCVE-2021-34480 should also be a priority,\u201d Kevin Breen, director of cyber-threat research at Immersive Labs, told Threatpost. \u201cIt is a low score in terms of CVSS, coming in at 6.8, but has been marked by Microsoft as \u2018Exploitation More Likely\u2019 because it is the type of attack commonly used to increase the success rate of spear phishing attacks to gain network access. Simple, but effective.\u201d\n\nThe Windows Graphic Component bug (**CVE-2021-34530**) allows attackers to remotely execute malicious code in the context of the current user, according to Microsoft \u2013 if they can social-engineer a target into opening a specially crafted file.\n\nAnother bug exists in the Windows MSHTML platform, also known as Trident (**CVE-2021-34534**). Trident is the rendering engine (mshtml.dll) used by Internet Explorer. The bug affects many Windows 10 versions (1607, 1809,1909, 2004, 20H2, 21H1) as well as Windows Server 2016 and 2019.\n\nBut while it potentially affects a large number of users, exploitation is not trivial.\n\n\u201cTo exploit, a threat actor would need to pull off a highly complex attack with user interaction \u2013 still entirely possible with the sophisticated attackers of today,\u201d said Peter Pflaster, technical product marketing manager at Automox.\n\nThe bug tracked as **CVE-2021-34535** impacts the Microsoft Remote Desktop Client, Microsoft\u2019s nearly ubiquitous utility for connecting to remote PCs.\n\n\u201cWith today\u2019s highly dispersed workforce, CVE-2021-34535, an RCE vulnerability in Remote Desktop Clients, should be a priority patch,\u201d said Breen. \u201cAttackers increasingly use RDP access as the tip of the spear to gain network access, often combining it with privilege escalation to move laterally. These can be powerful as, depending on the method, it may allow the attacker to authenticate in the network in the same way a user would, making detection difficult.\u201d\n\nIt\u2019s not as dangerous of a bug [as BlueKeep,](<https://threatpost.com/one-million-devices-open-to-wormable-microsoft-bluekeep-flaw/145113/>) according to Childs, which also affected RDP.\n\n\u201cBefore you start having flashbacks to BlueKeep, this bug affects the RDP client and not the RDP server,\u201d he said. \u201cHowever, the CVSS 9.9 bug is nothing to ignore. An attacker can take over a system if they can convince an affected RDP client to connect to an RDP server they control. On Hyper-V servers, a malicious program running in a guest VM could trigger guest-to-host RCE by exploiting this vulnerability in the Hyper-V Viewer. This is the more likely scenario and the reason you should test and deploy this patch quickly.\u201d\n\n## **Windows Print Spooler Bugs \u2013 Again**\n\nThe final critical bug is **CVE-2021-36936**, a Windows Print Spooler RCE bug that\u2019s listed as publicly known.\n\nPrint Spooler made headlines last month, when Microsoft patched what it thought was a minor elevation-of-privilege vulnerability in the service (CVE-2021-1675). But the listing was updated later in the week, after researchers from Tencent and NSFOCUS TIANJI Lab figured out it could be used for RCE \u2013 [requiring a new patch](<https://threatpost.com/microsoft-emergency-patch-printnightmare/167578/>).\n\nIt also disclosed a second bug, similar to PrintNightmare (CVE-2021-34527); and a third, [an EoP issue](<https://threatpost.com/microsoft-unpatched-bug-windows-print-spooler/167855/>) ([CVE-2021-34481](<https://support.microsoft.com/en-us/topic/kb5005652-manage-new-point-and-print-default-driver-installation-behavior-cve-2021-34481-873642bf-2634-49c5-a23b-6d8e9a302872>)).\n\n\u201cAnother month, another remote code-execution bug in the Print Spooler,\u201d said ZDI\u2019s Childs. \u201cThis bug is listed as publicly known, but it\u2019s not clear if this bug is a variant of PrintNightmare or a unique vulnerability all on its own. There are quite a few print-spooler bugs to keep track of. Either way, attackers can use this to execute code on affected systems. Microsoft does state low privileges are required, so that should put this in the non-wormable category, but you should still prioritize testing and deployment of this critical-rated bug.\u201d\n\nThe critical vulnerability is just one of three Print Spooler issues in the August Patch Tuesday release.\n\n\u201cThe specter of the PrintNightmare continues to haunt this patch Tuesday with three more print spooler vulnerabilities, CVE-2021-36947, CVE-2021-36936 and CVE-2021-34481,\u201d said Breen. \u201cAll three are listed as RCE over the network, requiring a low level of access, similar to PrintNightmare. Microsoft has marked these as \u2018Exploitation More Likely\u2019 which, if the previous speed of POC code being published is anything to go by, is certainly true.\u201d\n\n## **RCE Zero-Day in Windows Update Medic Service **\n\nThe actively exploited bug is tracked as **CVE-2021-36948** and is rated as important; it could pave the way for RCE via the Windows Update Medic Service in Windows 10 and Server 2019 and newer operating systems.\n\n\u201cUpdate Medic is a new service that allows users to repair Windows Update components from a damaged state such that the device can continue to receive updates,\u201d Automox\u2019 Jay Goodman explained. \u201cThe exploit is both low complexity and can be exploited without user interaction, making this an easy vulnerability to include in an adversary\u2019s toolbox.\u201d\n\nImmersive\u2019s Breen added, \u201cCVE-2021-36948 is a privilege-escalation vulnerability \u2013 the cornerstone of modern intrusions as they allow attackers the level of access to do things like hide their tracks and create user accounts. In the case of ransomware attacks, they have also been used to ensure maximum damage.\u201d\n\nThough the bug is being reported as being exploited in the wild by Microsoft, activity appears to remain limited or targeted: \u201cWe have seen no evidence of it at Kenna Security at this time,\u201d Jerry Gamblin, director of security research at Kenna Security (now part of Cisco) told Threatpost.\n\n## **Publicly Known Windows LSA Spoofing Bug**\n\nThe second publicly known bug (after the Print Spooler issue covered earlier) is tracked as **CVE-2021-36942**, and it\u2019s an important-rated Windows LSA (Local Security Authority) spoofing vulnerability.\n\n\u201cIt fixes a flaw that could be used to steal NTLM hashes from a domain controller or other vulnerable host,\u201d Immersive\u2019s Breen said. \u201cThese types of attacks are well known for lateral movement and privilege escalation, as has been demonstrated recently by a [new exploit called PetitPotam](<https://threatpost.com/microsoft-petitpotam-poc/168163/>). It is a post-intrusion exploit \u2013 further down the attack chain \u2013 but still a useful tool for attackers.\u201d\n\nChilds offered a bit of context around the bug.\n\n\u201cMicrosoft released this patch to further protect against NTLM relay attacks by issuing this update to block the LSARPC interface,\u201d he said. \u201cThis will impact some systems, notably Windows Server 2008 SP2, that use the EFS API OpenEncryptedFileRawA function. You should apply this to your Domain Controllers first and follow the additional guidance in [ADV210003](<https://msrc.microsoft.com/update-guide/vulnerability/ADV210003>) and [KB5005413](<https://support.microsoft.com/en-us/topic/kb5005413-mitigating-ntlm-relay-attacks-on-active-directory-certificate-services-ad-cs-3612b773-4043-4aa9-b23d-b87910cd3429>). This has been an ongoing issue since 2009, and, likely, this isn\u2019t the last we\u2019ll hear of this persistent issue.\u201d\n\nMicrosoft\u2019s next Patch Tuesday will fall on September 14.\n\nWorried about where the next attack is coming from?

This is in addition to [seven security flaws](<https://docs.microsoft.com/en-us/deployedge/microsoft-edge-relnotes-security>) it patched in the Microsoft Edge browser on August 5.\n\nChief among the patched issues is [CVE-2021-36948](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-36948>) (CVSS score: 7.8), an elevation of privilege flaw affecting Windows Update Medic Service \u2014 a service that enables remediation and protection of Windows Update components \u2014 which could be abused to run malicious programs with escalated permissions.\n\nMicrosoft's Threat Intelligence Center has been credited with reporting the flaw, although the company refrained from sharing additional specifics or detail on how widespread those attacks were in light of active exploitation attempts.\n\nTwo of the security vulnerabilities are publicly known at the time of release -\n\n * [CVE-2021-36942](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-36942>) (CVSS score: 9.8) - Windows LSA Spoofing Vulnerability\n * [CVE-2021-36936](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-36936>) (CVSS score: 8.8) - Windows Print Spooler Remote Code Execution Vulnerability\n\nWhile CVE-2021-36942 contains fixes to secure systems against NTLM relay attacks like [PetitPotam](<https://thehackernews.com/2021/07/new-petitpotam-ntlm-relay-attack-lets.html>) by blocking the LSARPC interface, CVE-2021-36936 resolves yet another remote code execution flaw in the Windows Print Spooler component.\n\n\"An unauthenticated attacker could call a method on the LSARPC interface and coerce the domain controller to authenticate against another server using NTLM,\" Microsoft said in its advisory for CVE-2021-36942; adding the \"security update blocks the affected API calls OpenEncryptedFileRawA and OpenEncryptedFileRawW through LSARPC interface.\"\n\nCVE-2021-36936 is also one among the three flaws in the Print Spooler service that Microsoft has fixed this month, with the two other vulnerabilities being [CVE-2021-36947](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-36947>) and (CVSS score: 8.2) and [CVE-2021-34483](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-34483>) (CVSS score: 7.8), the latter of which concerns an elevation of privilege vulnerability.\n\nIn addition, Microsoft has released [security updates](<https://support.microsoft.com/en-us/topic/kb5005652-manage-new-point-and-print-default-driver-installation-behavior-cve-2021-34481-873642bf-2634-49c5-a23b-6d8e9a302872>) to resolve a previously disclosed remote code execution in the Print Spooler service tracked as [CVE-2021-34481](<https://thehackernews.com/2021/07/microsoft-warns-of-new-unpatched.html>) (CVSS score: 8.8). This changes the default behavior of the \"[Point and Print](<https://docs.microsoft.com/en-us/windows-hardware/drivers/print/introduction-to-point-and-print>)\" feature, effectively preventing non-administrator users from installing or updating new and existing printer drivers using drivers from a remote computer or server without first elevating themselves to an administrator.\n\nAnother critical flaw remediated as part of Patch Tuesday updates is [CVE-2021-26424](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-26424>) (CVSS score: 9.9), a remote code execution vulnerability in Windows TCP/IP, which Microsoft notes \"is remotely triggerable by a malicious Hyper-V guest sending an ipv6 ping to the Hyper-V host. An attacker could send a specially crafted TCP/IP packet to its host utilizing the TCP/IP Protocol Stack (tcpip.sys) to process packets.\"\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### Software Patches From Other Vendors\n\nBesides Microsoft, patches have also been released by a number of other vendors to address several vulnerabilities, including -\n\n * [Adobe](<https://helpx.adobe.com/security.html/security/security-bulletin.ug.html>)\n * [Android](<https://source.android.com/security/bulletin/2021-08-01>)\n * [Cisco](<https://tools.cisco.com/security/center/publicationListing.x>)\n * [Citrix](<https://support.citrix.com/search/#/All%20Products?ct=Software%20Updates,Security%20Bulletins&searchText=&sortBy=Modified%20date&pageIndex=1>)\n * [Juniper Networks](<https://kb.juniper.net/InfoCenter/index?page=content&channel=SECURITY_ADVISORIES>)\n * Linux distributions [SUSE](<https://lists.suse.com/pipermail/sle-security-updates/2021-August/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=582222806>)\n * [Schneider Electric](<https://www.se.com/ww/en/work/support/cybersecurity/overview.jsp>)\n * [Siemens](<https://new.siemens.com/global/en/products/services/cert.html#SecurityPublications>), and\n * [VMware](<https://www.vmware.com/security/advisories.html>)\n \n\n\nFound this article interesting?

The attacks are said to have taken place since at least July 13.\n\nSince June, a series of \"PrintNightmare\" issues affecting the Windows print spooler service has come to light that could enable remote code execution when the component performs privileged file operations -\n\n * [**CVE-2021-1675**](<https://thehackernews.com/2021/06/researchers-leak-poc-exploit-for.html>) \\- Windows Print Spooler Remote Code Execution Vulnerability (Patched on June 8)\n * [**CVE-2021-34527**](<https://thehackernews.com/2021/07/microsofts-emergency-patch-fails-to.html>) \\- Windows Print Spooler Remote Code Execution Vulnerability (Patched on July 6-7)\n * [**CVE-2021-34481**](<https://thehackernews.com/2021/07/microsoft-warns-of-new-unpatched.html>) \\- Windows Print Spooler Remote Code Execution Vulnerability (Patched on August 10)\n * [**CVE-2021-36936**](<https://thehackernews.com/2021/08/microsoft-releases-windows-updates-to.html>) \\- Windows Print Spooler Remote Code Execution Vulnerability (Patched on August 10) \n * [**CVE-2021-36947**](<https://thehackernews.com/2021/08/microsoft-releases-windows-updates-to.html>) \\- Windows Print Spooler Remote Code Execution Vulnerability (Patched on August 10)\n * [**CVE-2021-34483**](<https://thehackernews.com/2021/08/microsoft-releases-windows-updates-to.html>) \\- Windows Print Spooler Elevation of Privilege Vulnerability (Patched on August 10)\n * [**CVE-2021-36958**](<https://thehackernews.com/2021/08/microsoft-security-bulletin-warns-of.html>) \\- Windows Print Spooler Remote Code Execution Vulnerability (Unpatched)\n\nCrowdStrike noted it was able to successfully prevent attempts made by the Magniber ransomware gang at exploiting the PrintNightmare vulnerability.\n\nVice Society, on the other hand, leveraged a variety of techniques to conduct post-compromise discovery and reconnaissance prior to bypassing native Windows protections for credential theft and privilege escalation.\n\n[](<https://thehackernews.com/images/-JlsTWIHVgX4/YRYltMOGBKI/AAAAAAAADhQ/pzUFIcW6y0ABjOe3PuUQE5cPSnEOvGP9ACLcBGAsYHQ/s0/ransomware.jpg>)\n\nSpecifically, the attacker is believed to have used a malicious library associated with the PrintNightmare flaw (CVE-2021-34527) to pivot to multiple systems across the environment and extract credentials from the victim.\n\n\"Adversaries are constantly refining their approach to the ransomware attack lifecycle as they strive to operate more effectively, efficiently, and evasively,\" the researchers said. \"The use of the vulnerability known as PrintNightmare shows that adversaries are paying close attention and will quickly incorporate new tools that they find useful for various purposes during their attacks.\"\n\n \n\n\nFound this article interesting?
