Unauthenticated disclosure of authentication information
Published May 10, 2022 · Updated Jan 2, 2025
Information disclosure in affected Microsoft Windows releases allows remote attackers to read authentication information over a network. Microsoft has not published the affected authentication operation, the input it mishandles, or the specific information exposed. Exploitation requires no privileges or user interaction but has high attack complexity; no safely observable request or vulnerable runtime state is documented.

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.
