Today, Microsoft released its scheduled September set of patches. This update addresses 79 different vulnerabilities. Seven of these vulnerabilities are rated critical. Four vulnerabilities are already being exploited and have been made public. 

Noteworthy Vulnerabilities:

CVE-2024-43491: This “downgrade” vulnerabilities. An attacker can remove previously applied patches and exploit older vulnerabilities. This issue only affects Windows 15 Version 1507, which is EOL. It appears to differ from the similar vulnerabilities (CVE-2024-38202 and CVE-2024-21302) made public by Alon Leviev during Blackhat this year. These two vulnerabilities appear to remain unpatched.

CVE-2024-38014: A Windows Installer issue could lead to attackers gaining System access.

CVE-2024-38217: Yet another “Mark of the Web” bypass that is already exploited and could be used to trick a victim into installing malware.

CVE-2024-38226: Similar to the above vulnerability, a security feature bypass in Publisher.

Microsoft also patched four remote code execution vulnerabilities in Sharepoint, but the lower CVSS score indicates that exploitation will require access and specific prerequisites.

CVE-2024-38119: A critical vulnerability in the Windows NAT code. The low CVSS score is likely because this is not enabled by default.
