Authenticated spoofing via improper input validation
Published Sep 10, 2024 · Updated Aug 10, 2026
Spoofing in Microsoft Windows Remote Desktop Licensing Service allows remote authenticated users to compromise affected servers. Microsoft maps the flaw to improper input validation but has not published the input, handler, or incorrect validation operation. The licensing role must be installed and network-reachable; successful exploitation compromises data confidentiality and integrity and interrupts service.
