The Multi-State Information Sharing and Analysis Center (MS-ISAC), funded by DHS, exists to improve the overall cybersecurity posture of state, local, tribal, and territorial governments and is designated as the key resource for cyber threat prevention, protection, response, and recovery.

New MS-ISAC Advisory

DATE(S) ISSUED: 03/10/2020

SUBJECT: Critical Patches Issued for Microsoft Products, March 10, 2020

OVERVIEW:

Multiple vulnerabilities have been discovered in Microsoft products. Successful exploitation 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.

SYSTEMS AFFECTED:

  • Microsoft Windows
  • Microsoft Edge (EdgeHTML-based)
  • Microsoft Edge (Chromium-based)
  • Internet Explorer
  • Microsoft Exchange Server
  • Microsoft Office and Microsoft Office Services and Web Apps
  • Windows Defender
  • Visual Studio
  • Azure
  • Microsoft Dynamics

RISK:

Businesses:

  • Large and medium businesses: High
  • Small businesses: Medium
  • Home users: Low

RECOMMENDATIONS:

We recommend the following actions be taken:

  • Apply appropriate patches or appropriate mitigations provided by Microsoft to vulnerable systems immediately after appropriate testing.
  • 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 provided by unknown or untrusted sources.
  • Inform and educate users regarding threats posed by hypertext links contained in emails or attachments especially from untrusted sources. Apply the Principle of Least Privilege to all systems and services.
