Microsoft February 2023 Patch Tuesday
Microsoft today patched 80 different vulnerabilities. This includes the Chromium vulnerabilities affecting Microsoft Edge. Nine vulnerabilities are rated as "Critical" by Microsoft.
Three of the vulnerabilities, all rated "important", are already being exploited:
CVE-2023-21715: Microsoft Publisher Security Feature Bypass. This vulnerability will allow the execution of macros bypassing policies blocking them.
CVE-2023-23376: Windows Common Log File Ssytem Driver Elevation of Privilege Vulnerability
CVE-2023-21823: Windows Graphics Component Remote Code Execution Vulnerability. Patches for this vulnerability may only be available via the Microsoft Store. Make sure you have these updates enabled.
Some additional vulnerabilities of interest:
CVE-2023-21803: Windows iSCSI Discovery Service Remote Code Execution Vulnerability. Likely not the most common issue to be patched this month, but something that may easily be missed. This vulnerability, if exploited, could be used for lateral movement.
CVE-2023-21716: Microsoft Word Remote Code Execution Vulnerability. Word is always a great target as it offers a large attack surface. No known exploit for this vulnerability, but its CVSS score of 9.8 will attract some attention. The rating of "critical" implies that it is not necessary to open the document to trigger the vulnerability.
Visual Studio: Several vulnerabilities, two of them critical, affect Visual Studio. Attacks against developers are often not well documented but appear on the rise.
