Important Microsoft Vulnerabilities Patched

CVE-2022-21984 – Windows DNS Server Remote Code Execution (RCE) Vulnerability

This vulnerability has a CVSSv3.1 score of 8.8/10. The Microsoft DNS server has a Remote Code Execution (RCE) flaw that has been fixed with this patch. The server is only affected if dynamic updates are enabled, but this is a relatively common configuration. An attacker might entirely take control of your DNS and execute code with elevated privileges if you have this set up in your environment.  

Exploitability Assessment: Exploitation Less Likely.

CVE-2022-21989 – Windows Kernel Elevation of Privilege Vulnerability

This vulnerability has a CVSSv3.1 score of 7.8/10. A low-privilege AppContainer could be used to launch a successful attack. The attacker could get elevated privileges, allowing them to run code or access resources with a greater level of integrity than the AppContainer execution environment.

Exploitability Assessment: Exploitation More Likely.

CVE-2022-22003 – Microsoft Office Graphics Remote Code Execution (RCE) Vulnerability

This vulnerability has a CVSSv3.1 score of 7.8/10. This Remote Code Execution (RCE) vulnerability affects Microsoft Office Graphics. For successful exploitation, a user needs to be tricked into running malicious files.

Exploitability Assessment: Exploitation Less Likely.

CVE-2022-22005 – Microsoft SharePoint Server Remote Code Execution (RCE) Vulnerability

This vulnerability has a CVSSv3.1 score of 8.8/10. This Remote Code Execution (RCE) vulnerability affects Microsoft SharePoint Server. An attacker must be authenticated and have page creation access on SharePoint to exploit the flaw.

Exploitability Assessment: Exploitation More Likely.

Adobe Patch Tuesday – February 2022

Adobe released updates to fix 17 CVEs affecting Premiere Rush, Illustrator, Photoshop, AfterEffects, and Creative Cloud Desktop Application. Of these 17 vulnerabilities, five (5) are treated as Critical.

Adobe has released security updates for Illustrator, Photoshop, and AfterEffects for Windows and macOS. These updates address multiple critical, important, and moderate vulnerabilities.

Successful exploitation of these vulnerabilities could lead to application denial-of-service (DoS), arbitrary code execution, privilege escalation, and memory leaks.
