Three zero-days fixed, none actively exploited

This month’s Patch Tuesday includes fixes for three publicly disclosed zero-day vulnerabilities. The good news is that none of these vulnerabilities were actively exploited in attacks.

Microsoft classifies a vulnerability as a zero-day if it is publicly disclosed or actively exploited with no official fix available.

The publicly disclosed vulnerabilities fixed as part of the March 2022 Patch Tuesday are:

  • CVE-2022-21990 – Remote Desktop Client Remote Code Execution Vulnerability
  • CVE-2022-24459 – Windows Fax and Scan Service Elevation of Privilege Vulnerability
  • CVE-2022-24512 – .NET and Visual Studio Remote Code Execution Vulnerability

While none of these vulnerabilities have been used in attacks, Microsoft states that there are public proof-of-concept exploits for CVE-2022-21990 and CVE-2022-24459.

Patch Tuesday

Other vulnerabilities of interest this month that Microsoft believes are more likely to be targeted by threat actors are:

  • CVE-2022-24508 – Windows SMBv3 Client/Server Remote Code Execution Vulnerability
  • CVE-2022-23277 – Microsoft Exchange Server Remote Code Execution Vulnerability

Now that Microsoft has issued patches for these vulnerabilities, it should be expected for threat actors to analyze the vulnerabilities to learn how to exploit them.
