Unauthenticated Kerberos privilege escalation
Published Sep 13, 2022 · Updated Mar 11, 2025
Windows Kerberos in Microsoft Windows Server 2008, 2012, 2016, 2019, and 2022 allows remote attackers to gain elevated privileges via network requests. Microsoft has not published the specific Kerberos component or operation that mishandles untrusted input, so the exploit mechanism remains undisclosed. Exploitation requires no authentication or user interaction but has high attack complexity; successful attacks can compromise confidentiality, integrity, and availability of the server.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
