A list of the updates can be found on this Microsoft page. Details about the update packages for Windows, Office, etc. are available in separate blog posts.

Notes on the updates

Windows 10 version 20H2 to 21H2 use a common core and have an identical set of system files. Therefore, the same security update will be delivered for these Windows 10 versions. Information on how to enable the features of Windows 10, which is done through an Enablement Package update, can be found in this Techcommunity post.

All Windows 10 updates are cumulative. The monthly patchday update includes all security fixes for Windows 10 and all non-security fixes through patchday. In addition to vulnerability security patches, the updates include security enhancement measures. Microsoft is integrating the Servicing Stack Updates (SSUs) into the Latest Cumulative Updates (LCUs) for newer versions of Windows 10. A list of the latest SSUs can be found at ADV990001 (although the list is not always up-to-date).

Windows 7 SP1 is no longer supported as of January 2020. Only customers with a 3rd year ESU license (or bypass measures) will still receive updates. With the current ESU bypass lets install the update. Updates can also be downloaded from the Microsoft Update Catalog. The updates for Windows RT 8.1 and Microsoft Office RT are only available via Windows Update.

Vulnerabilities fixed

The September 2022 security updates fix 63 vulnerabilities, including 5 critical and one 0-day vulnerability. A list of all covered CVEs can be found on this Microsoft page.

  • CVE-2022-37969: Windows Common Log File System Driver Elevation of Privilege Vulnerability, Important,  EoP vulnerability in the Windows Common Log File System (CLFS) driver. According to Microsoft, this vulnerability has already been exploited. They also point out that it was publicly disclosed before a patch was available.
  • CVE-2022-24521: Important, a similar vulnerability in CLFS, was patched earlier this year as part of Microsoft's Patch Tuesday release in April. The CVE-2022-24521 vulnerability was reported to Microsoft by the National Security Agency (NSA) and CrowdStrike, which has also been exploited in the wild. CVE-2022-37969 has been attributed to multiple groups, including CrowdStrike, although it is currently unclear whether CVE-2022-37969 may be a workaround for patching CVE-2022-24521.
  • CVE-2022-34718: an RCE in Windows TCP/IP that received a CVSSv3 score of 9.8 and was rated "Exploitation More Likely" according to Microsoft's Exploitability Index. This vulnerability can only be exploited against systems with Internet Protocol Security (IPsec) enabled. If successfully exploited, an unauthenticated attacker could gain remote code execution. Microsoft has released patches for all supported versions of Windows, including Server Core editions.
  • CVE-2022-34721 und CVE-2022-34722: Windows Internet Key Exchange (IKE) Protocol Extensions Remote Code Execution Vulnerability, Critical, RCE vulnerabilities in the Windows IKE protocol extensions, which received a CVSSv3 score of 9.8 and were rated as Exploitation Less Likely. The IKE protocol is a component of IPsec used to establish security connections (relationships between devices based on shared security attributes). These vulnerabilities would allow an unauthenticated, remote attacker to send a specially crafted IP packet to a target with IPsec enabled and achieve remote code execution. IPsec is used to protect sensitive data and is often used in virtual private networks. Below is the list of critical and important security updates – details of which will be reported in separate blog posts.
  • CVE-2022-37956, CVE-2022-37957 und CVE-2022-37964: Windows Kernel Elevation of Privilege Vulnerability, Important, EoP vulnerabilities affecting the Windows kernel. All three vulnerabilities received CVSSv3 scores of 7.8 and could allow an attacker to gain SYSTEM-level privileges if exploited. Of the three vulnerabilities, only CVE-2022-37957 was rated as Exploitation More Likely. Oddly enough, all three affect different versions of Windows. For example, CVE-2022-37964 only affects Windows 7, Windows Server 2008 and 2008 R2. CVE-2022-37956 affects all supported versions of Windows and Windows Server, while CVE-2022-37957 affects only Windows 10 and later, including Windows Server versions 2016, 2019 and 2022.
