February 8, 2022 – Critical Patches Issued for Microsoft Products

Fortify Security Team
Feb 8, 2022

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.

THREAT INTELLIGENCE:  There are currently no reports of these vulnerabilities being exploited in the wild.

SYSTEMS AFFECTED:

  • Azure Data Explorer
  • Kestrel Web Server
  • Microsoft Dynamics
  • Microsoft Dynamics GP
  • Microsoft Edge (Chromium-based)
  • Microsoft Office
  • Microsoft Office Excel
  • Microsoft Office Outlook
  • Microsoft Office SharePoint
  • Microsoft Office Visio
  • Microsoft OneDrive
  • Microsoft Teams
  • Microsoft Windows Codecs Library
  • Power BI
  • Roaming Security Rights Management Services
  • Role: DNS Server
  • Role: Windows Hyper-V
  • SQL Server
  • Visual Studio Code
  • Windows Common Log File System Driver
  • Windows DWM Core Library
  • Windows Kernel
  • Windows Kernel-Mode Drivers
  • Windows Named Pipe File System
  • Windows Print Spooler Components
  • Windows Remote Access Connection Manager
  • Windows Remote Procedure Call Runtime

RISK:
Government:

  • Large and medium government entities: High
  • Small government entities: Medium

Businesses:

  • Large and medium business entities: High

Home users: Low

TECHNICAL SUMMARY:

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 below:

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.

RECOMMENDATIONS:
We recommend the following actions be taken:

  • Apply appropriate patches or appropriate mitigations provided by Microsoft to vulnerable systems immediately after appropriate testing.
  • 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.
