Today's Microsoft patch Tuesday addresses 132 vulnerabilities. Nine of the vulnerabilities are rated as Critical, and 6 of these are listed as exploited prior in the wild.

In particular, CVE-2023-36884 includes a remote code execution vulnerability via Microsoft Word documents and was linked to the Storm-0978 threat actor.  Microsoft Threat Intelligence has a blog entry which discusses this situation. Take special note of the mitigations which are recommended, as updates will likely be released out-of-cycle for this one.

Other exploited vulnerabilities include:

CVE-2023-35311 is a Microsoft Outlook Security Feature bypass which was being exploited in the wild which worked in the preview pane and bypasses security warning.

CVE-2023-32046 is an actively exploited privilege elevation vulnerability in Windows MSHTML which could be exploited by opening a specially crafted file in email or a malicious website.

CVE-2023-32049 is a security feature bypass vulnerability with Windows SmartScreen which was being exploited to prevent the Open File - Security Warning prompt when downloading/opening files from the Internet.

CVE-2023-36874 is an actively exploited privilege escalation flaw which could allow threat actors to gain local administrator privileges.  Attackers would need to have local access to the targeted machine and the user be able to create folder and performance traces to fully exploit this vulnerability.

Microsoft also issued a high-impact advisory (ADV230001) where attackers where abusing the drivers being certified by Microsoft's Windows Hardware Developer Program (MWHDP) as a post-exploitation activity.  The implicated developer accounts were suspected, and Microsoft has taken steps to untrust drivers which were improperly certified.
