Remote code execution in Microsoft Remote Desktop Client on affected Windows releases allows remote attackers to run code after user interaction. Microsoft has not published the faulty component or operation that processes attacker-controlled RDP content. Exploitation requires a user to connect the client to a malicious RDP server, and code runs in that user's security context.
