Unauthenticated Remote Desktop service interruption
Published Jun 8, 2021 · Updated Aug 3, 2024
Denial of service in Microsoft Windows Remote Desktop Services allows remote attackers to interrupt the service via network traffic. Microsoft's public advisory identifies Remote Desktop Services but does not disclose the request, parser, or operation that mishandles network input. Remote Desktop must be enabled and network-reachable; exploitation interrupts the service without reported data disclosure or modification.
