## Technical details

An improper authorization vulnerability (CWE-285) exists in Microsoft Windows Admin Center. The flaw allows an attacker who is already authenticated to the local system with low-level privileges to bypass authorization checks and execute arbitrary code. The attack vector is local, meaning the attacker must have existing access to the host machine, but the exploit requires no user interaction and has a low complexity. Successful exploitation results in a total loss of confidentiality, integrity, and availability. Microsoft has addressed this in versions 2.7.4 and later.

## Affected products

- Microsoft Windows Admin Center 1809.0 to 2.7.4
