Critical Patches Issued for Microsoft Products, January 11, 2022

ITS Advisory Number: 
2022-004
Date(s) Issued: 
Tuesday, January 11, 2022
Subject: 
Critical Patches Issued for Microsoft Products, January 11, 2022
Overview: 

Multiple vulnerabilities have been discovered in Microsoft products, the most severe of which could allow for remote code execution in the context of the logged on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.

Description: 

Multiple vulnerabilities have been discovered in Microsoft products, the most severe of which could allow for remote code execution.

 

A full list of all vulnerabilities can be found at the link under the References section.

 

Successful exploitation of the most severe of these vulnerabilities could result in an attacker gaining the same privileges as the logged-on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.

 

Actions: 
  • After appropriate testing, immediately apply patches or mitigations provided by Microsoft to vulnerable systems.
  • Apply the Principle of Least Privilege to all systems and services, and run all software as a non-privileged user (one without administrative rights) to diminish the effects of a successful attack.
  • Remind all users not to visit untrusted websites or follow links/open files provided by unknown or untrusted sources.
