CVE-2021-43890 Being Exploited in The Wild

You should consider patching your system as soon as you can and communicate with your IT team as often as possible based on the changes you are making.

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.

There are currently reports of CVE-2021-43890 being exploited in the wild to spread malware such as Emotet, Trickbot, and Bazaloader.
