Information disclosure through undisclosed protocol bypass
Published Jan 11, 2022 · Updated Jan 2, 2025
Security feature bypass in Microsoft Windows Workstation Service allows remote attackers to read protected information over RPC with user interaction. Microsoft has not published the affected method or the incorrect operation performed on untrusted protocol input. The endpoint is reachable through RPC over SMB, but exploitation requires user interaction and has no reported modification or service-interruption impact.
