Unauthenticated code execution via integer underflow
Published Jul 9, 2024 · Updated Feb 10, 2026
Integer underflow in Microsoft Windows Remote Desktop Licensing Service allows remote attackers to execute arbitrary code over the network. Microsoft identifies the weakness class but has not disclosed the affected function, integer operation, or malformed request field. Exploitation requires the Remote Desktop Licensing role to be installed and reachable through its RPC service; successful exploitation runs attacker-controlled code on the server.
