Security Advisory – Zero Day – Follina



Teqworks Managed Security has been monitoring the development of an active zero-day threat, referred to as “Follina” (CVE-2022-30190).  This vulnerability was originally identified on May 27, and security platforms continue to update as details emerge.

In short, an attacker can utilize the Microsoft Support Diagnostic Tool (MSDT) to run arbitrary code on a computer or server.  MSDT can be run by executing a URL through a known acceptable application, such as Word, which then allows the arbitrary code to run with permissions of the logged-in user.

Microsoft has published workarounds and advisories to disable the vulnerability.  Teqworks is evaluating machines that are exposed to this vulnerability and applying the fixes as they are identified.

Teqworks clients under our Advanced Threat Protection service are being actively monitored and remediated by our 24×7 Security Operations Center partner.
