Missing authentication in Microsoft Windows Remote Desktop Licensing Service allows remote attackers to bypass a security feature over a network. Microsoft has not disclosed the affected function, request path, or authentication check that the service omits. The licensing service must be network-reachable, and the documented impact is unauthorized access to confidential information without modification or service interruption.
