Remote service interruption via undisclosed authentication flaw
Published Jul 9, 2024 · Updated Feb 10, 2026
Improper authentication in Microsoft Windows Server Remote Desktop Licensing Service allows remote attackers to interrupt the service. Microsoft has not disclosed the affected request handler or the incorrect authentication operation performed on untrusted network input. The licensing role must be installed and network-reachable; exploitation needs no credentials or user interaction but has high attack complexity.
