Authenticated information disclosure via uninitialized RRAS resource
Published Aug 12, 2025 · Updated Feb 13, 2026
Information disclosure in Microsoft Windows Server RRAS allows remote authenticated users to read uninitialized data over a network. Microsoft identifies the mechanism only as RRAS using an uninitialized resource and has not disclosed the responsible function, protocol message, or data path. Exploitation requires low-privileged authorization and user interaction, and the disclosed data affects confidentiality without reported modification or service interruption.
