Attracting more than a half-million annual readers, this is the security community's go-to destination for technical breakdowns of the latest threats, critical vulnerability disclosures and cutting-edge research.

Patch Tuesday, March 2020

Today marks Microsoft's March Patch Tuesday. While it may not be on the top of everyone's March priority list, 116 CVEs suggest that you don't ignore this Patch Tuesday.

Of the 116 CVEs patched today, 26 are rated as "Critical" and represent the usual suspects we see month to month. Specifically, you'll find the various Remote Code Execution (RCE) vulnerabilities in the Windows Scripting Engine, which is used primarily in the Edge and Internet Explorer web browsers. Rounding out the Critical list are RCE vulnerabilities in Dynamics Business Central and in LNK files, where a malicious shortcut LNK file could trigger arbitrary code execution.

The list of CVEs rated as "Important" is a long one with 90 CVEs patched. The majority of the vulnerabilities are Elevation of Privilege, which attackers rely on to expand their access from a general low-level user to full system or even network access. This includes privilege escalation in Azure DevOps, Windows OS including the Kernel, and Microsoft Defender, a component that's supposed to bring more security, not introduce risk. There are also multiple RCE vulnerabilities in Microsoft Word, so don't accept any odd documents from strangers.

Luckily none of the CVEs patched today have any public exploits available, but as we all know, that's just a matter of time. So get to patching, and don't forget to wash your hands before and after!
