Privilege escalation via Remote Credential Guard relay

Published Jun 15, 2022 · Updated Jan 2, 2025

Improper authentication in Windows Remote Credential Guard allows remote authenticated users to gain elevated privileges through credential relay. The credential-handling path accepts relayed Remote Credential Guard authentication; Microsoft has not publicly identified the exact function or missing validation. Exploitation requires low-privileged access and environment-specific information, and it can bypass authentication or elevate privileges within the affected system.
