Multiple vulnerabilities have been discovered in Microsoft products, the most severe of which could allow for remote code execution. 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.



The Windows Win32k Elevation of Privilege Vulnerability (CVE-2021-1732), which allows an attacker or malicious program to elevate their privileges to administrative privileges, has been seen exploited in the wild. In addition, the Package Managers Configurations Remote Code Execution Vulnerability (CVE-2021-24105) has a proof of concept, which is available to the public.
