July also marks a dramatic jump in the volume of vulnerabilities, surpassing the number Microsoft collectively addressed as part of its updates in [May](<https://thehackernews.com/2021/05/latest-microsoft-windows-updates-patch.html>) (55) and [June](<https://thehackernews.com/2021/06/update-your-windows-computers-to-patch.html>) (50).\n\nChief among the security flaws actively exploited are as follows \u2014\n\n * **CVE-2021-34527** (CVSS score: 8.8) - Windows Print Spooler Remote Code Execution Vulnerability (publicly disclosed as \"[PrintNightmare](<https://thehackernews.com/2021/07/microsofts-emergency-patch-fails-to.html>)\")\n * **CVE-2021-31979** (CVSS score: 7.8) - Windows Kernel Elevation of Privilege Vulnerability\n * **CVE-2021-33771** (CVSS score: 7.8) - Windows Kernel Elevation of Privilege Vulnerability\n * **CVE-2021-34448** (CVSS score: 6.8) - Scripting Engine Memory Corruption Vulnerability\n\nMicrosoft also stressed the high attack complexity of CVE-2021-34448, specifically stating that the attacks hinge on the possibility of luring an unsuspecting user into clicking on a link that leads to a malicious website hosted by the adversary and contains a specially-crafted file that's engineered to trigger the vulnerability.\n\nThe other five publicly disclosed, but not exploited, zero-day vulnerabilities are listed below \u2014\n\n * **CVE-2021-34473** (CVSS score: 9.1) - Microsoft Exchange Server Remote Code Execution Vulnerability\n * **CVE-2021-34523** (CVSS score: 9.0) - Microsoft Exchange Server Elevation of Privilege Vulnerability\n * **CVE-2021-33781** (CVSS score: 8.1) - Active Directory Security Feature Bypass Vulnerability\n * **CVE-2021-33779** (CVSS score: 8.1) - Windows ADFS Security Feature Bypass Vulnerability\n * **CVE-2021-34492** (CVSS score: 8.1) - Windows Certificate Spoofing Vulnerability\n\n\"This Patch Tuesday comes just days after out-of-band updates were released to address PrintNightmare \u2014 the critical flaw in the Windows Print Spooler service that was found in all versions of Windows,\" Bharat Jogi, senior manager of vulnerability and threat research at Qualys, told The Hacker News.\n\n\"While MSFT has released updates to fix the vulnerability, users must still ensure that necessary configurations are set up correctly. Systems with misconfigurations will continue to be at risk of exploitation, even after the latest patch has been applied. PrintNightmare was a highly serious issue that further underscores the importance of marrying detection and remediation,\" Jogi added.\n\nThe PrintNightmare vulnerability has also prompted the U.S. Cybersecurity and Infrastructure Security Agency (CISA) to [release an emergency directive](<https://us-cert.cisa.gov/ncas/current-activity/2021/07/13/cisa-issues-emergency-directive-microsoft-windows-print-spooler>), urging federal departments and agencies to apply the latest security updates immediately and disable the print spooler service on servers on Microsoft Active Directory Domain Controllers.\n\nAdditionally, Microsoft also rectified a security bypass vulnerability in Windows Hello biometrics-based authentication solution ([CVE-2021-34466](<https://www.cyberark.com/resources/threat-research-blog/bypassing-windows-hello-without-masks-or-plastic-surgery>), CVSS score: 5.7) that could permit an adversary to spoof a target's face and get around the login screen.\n\nOther critical flaws remediated by Microsoft include remote code execution vulnerabilities affecting Windows DNS Server (CVE-2021-34494, CVSS score 8.8) and Windows Kernel (CVE-2021-34458), the latter of which is rated 9.9 on the CVSS severity scale.\n\n\"This issue allows a single root input/output virtualization (SR-IOV) device which is assigned to a guest to potentially interfere with its Peripheral Component Interface Express (PCIe) siblings which are attached to other guests or to the root,\" Microsoft noted in its advisory for CVE-2021-34458, adding Windows instances hosting virtual machines are vulnerable to this flaw.\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\nAlongside Microsoft, patches have also been released by a number of other vendors to address several vulnerabilities, including \u2014\n\n * [Adobe](<https://helpx.adobe.com/security.html/security/security-bulletin.ug.html>)\n * [Android](<https://source.android.com/security/bulletin/2021-07-01>)\n * [Apache Tomcat](<https://mail-archives.us.apache.org/mod_mbox/www-announce/202107.mbox/%3Cd050b202-b64e-bc6f-a630-2dd83202f23a%40apache.org%3E>)\n * [Cisco](<https://tools.cisco.com/security/center/publicationListing.x>)\n * [Citrix](<https://support.citrix.com/article/CTX319750>)\n * [Juniper Networks](<https://kb.juniper.net/InfoCenter/index?page=content&id=JSA11180&cat=SIRT_1&actp=LIST>)\n * Linux distributions [SUSE](<https://lists.suse.com/pipermail/sle-security-updates/2021-July/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=580617506>)\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?

In all, Microsoft patched 116 bugs. Twelve bugs are rated critical, 103 rated important and one classified as moderate in severity.\n\nBugs under active attack include a critical scripting engine memory corruption ([CVE-2021-34448](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-34448>)) flaw and two additional Windows kernel elevation-of-privilege vulnerabilities ([CVE-2021-31979](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-31979>), [CVE-2021-33771](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-33771>)), both with a severity rating of important. \n[](<https://threatpost.com/newsletter-sign/>)The hundred-plus bug fixes add to a rough July for Microsoft, which rolled out an out-of-band fix for a Windows print spooler remote-code-execution vulnerability ([CVE-2021-34527](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-34527>)), dubbed [PrintNightmare](<https://threatpost.com/microsoft-emergency-patch-printnightmare/167578/>), earlier this month. The nightmare bug, first disclosed in April, was later discovered to be more serious than initially thought.\n\n## **Public, But Not Exploited **\n\nFive of the bugs patched by Microsoft ([CVE-2021-34473](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-34473>), [CVE-2021-33781](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-33781>), [CVE-2021-34523](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-34523>), [CVE-2021-33779](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-33779>), [CVE-2021-34492](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-34492>)) were publicly known, albeit not exploited. Only one of those bugs (CVE-2021-34473), a Microsoft Exchange Server remote code execution (RCE) vulnerability, has a severity rating of critical, with a CVSS score of 9.1. The bug, one of the highest rated in terms of importance to fix this month, was part of Microsoft\u2019s April Patch Tuesday roundup of fixes, according to commentary by [Cisco Talos](<https://blog.talosintelligence.com/2021/07/microsoft-patch-tuesday-for-july-2021.html>).\n\n\u201cThis vulnerability was already patched in Microsoft\u2019s April security update but was mistakenly not disclosed. Users who already installed the April 2021 update are already protected from this vulnerability, though it is worth noting that this issue was part of a series of zero-days in Exchange Server used in a wide-ranging APT attack,\u201d wrote Talos authors Jon Munshaw and Jaeson Schultz.\n\n## **Patching Priorities **\n\nThe most pressing of bugs is a memory corruption vulnerability (CVE-2021-34448) in Windows Server\u2019s scripting engine that is triggered when the user opens a specially crafted file, either attached to an email or a compromised website.\n\n\u201c[This bug] is the most serious vulnerability for me. It is elegant in its simplicity, letting an attacker gain remote code execution just by getting the target to visit a domain,\u201d wrote Kevin Breen, director of cyber threat research with Immersive Labs, in his Patch Tuesday commentary. \u201cWith malicious, yet professional looking, domains carrying valid TLS certificates a regular feature nowadays, seamless compromise would be a trivial matter. Victims could even be attacked by sending .js or .hta files in targeted phishing emails.\u201d\n\nCisco Talos advises system admin to prioritize a patch for a critical bug ([CVE-2021-34464](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-34464>)) in Microsoft\u2019s free Defender anti-virus software. \u201cThis issue could allow an attacker to execute remote code on the victim machine. However, users do not need to take any actions to resolve this issue, as the update will automatically install. The company has listed steps in its advisory users can take to ensure the update is properly installed,\u201d wrote Munshaw and Schultz.\n\nResearchers have also identified three SharePoint Server bugs ([CVE-2021-34520](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-34520>), [CVE-2021-34467](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-34467>), [CVE-2021-34468](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-34468>)) as priority patches. Each allow an attacker to execute remote code on the victim machine. All are rated important. However, Microsoft reports that exploitation is \u201cmore likely\u201d with these vulnerabilities, Talos said.\n\nZero Day Initiative\u2019s Dustin Childs recommends tackling ([CVE-2021-34458](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-34458>)), a Windows kernel vulnerability. \u201cIt\u2019s rare to see remote code execution in a kernel bug, but this is that rare exception. This bug impacts systems hosting virtual machines with single root input/output virtualization (SR-IOV) devices,\u201d [he wrote](<https://www.zerodayinitiative.com/blog/2021/7/13/the-july-2021-security-update-review>).\n\n\u201cIt\u2019s not clear how widespread this configuration is, but considering this bug rates as a CVSS 9.9, it\u2019s not one to ignore. If you have virtual machines in your environment, test and patch quickly,\u201d Childs added.\n\nIn related news, [Adobe\u2019s July patch roundup](<https://threatpost.com/adobe-patches-critical-acrobat/167743/>), also released Tuesday, includes fixes for its ubiquitous and free PDF reader Acrobat 2020 and other software such as Illustrator and Bridge.

"\n\n[Microsoft has patched another 117 CVEs](<https://msrc.microsoft.com/update-guide/releaseNote/2021-Jul>), returning to volumes seen in early 2021 and most of 2020. It would appear that the recent trend of approximately 50 vulnerability fixes per month was not indicative of a slowing pace. This month there were 13 vulnerabilities rated Critical with nearly the rest being rated Important. Thankfully, none of the updates published today require additional steps to remediate, so administrators should be able to rely on their normal patching process. Once[ CVE-2021-34527](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-34527>) has been remediated, priority should be to patch public facing DNS and Exchange servers, followed by Workstations, SharePoint servers, and finally Office applications.\n\nIt seems like the PrintNightmare is nearly over. While the past two weeks have been a frenzy for the security community there has been no new information since the end of last week when Microsoft made a final revision to their guidance on[ CVE-2021-34527](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-34527>). If you haven\u2019t patched this yet, this is your daily reminder. For further details [please see our blog](<https://www.rapid7.com/blog/post/2021/06/30/cve-2021-1675-printnightmare-patch-does-not-remediate-vulnerability/>) on the topic.\n\n## Multiple Critical DNS Vulnerabilities Patched\n\nAdministrators should focus their efforts on the 11 vulnerabilities in Windows DNS server to reduce the most risk. The two most important of these vulnerabilities are [CVE-2021-34494](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-34494>) and [CVE-2021-33780](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-33780>). Exploitation of either of these vulnerabilities would result in Remote Code Execution with SYSTEM privileges without any user interaction via the network. Given the network exposure of DNS servers these vulnerabilities could prove to be troublesome if an exploit were to be developed. Microsoft lists [CVE-2021-33780](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-33780>) as \u201cExploitation More Likely\u201d so it may only be a matter of time before attackers attempt to make use of these flaws.\n\n## New Exchange Updates Available\n\nOnly 4 of the 7 Exchange CVEs being disclosed this month are new. The two most severe vulnerabilities were patched in back in April and were mistakenly not disclosed. This means that if you applied the April 2021 updates you will not need to take any action for [CVE-2021-34473](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-34473>), [CVE-2021-34523](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-34523>), or [CVE-2021-33766](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-33766>). Of the 4 newly patched vulnerabilities the most notable is [CVE-2021-31206](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-31206>), a remote code execution flaw discovered in the recent Pwn2Own competition. \n\n## Scripting Engine Exploited in the Wild\n\nExploitation of [CVE-2021-34448](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-34448>) has been observed in the wild by researchers. There are no details on the frequency or spread of this exploit. This vulnerability requires the user to visit a link to download a malicious file. As with other vulnerabilities that require user interaction, strong security hygiene is the first line of defense.\n\n## Summary Tables\n\nHere are this month's patched vulnerabilities split by the
