Protected-data tampering via improper authentication
Published Feb 11, 2025 · Updated Feb 26, 2026
Improper authentication in Microsoft Windows Remote Desktop Configuration Service allows remote attackers to alter protected data after user interaction. Microsoft has not published the flawed authentication operation or the input that reaches it. Exploitation requires a remote attack with user interaction, and the published impact is limited to unauthorized reading or modification of data without service interruption.
