#Windows Remote Desktop

The following mitigation may be helpful in your situation. In all cases, Microsoft strongly recommends that you install the updates for this vulnerability as soon as possible even if you plan to leave Remote Desktop Licensing Service disabled: **1\. Disable Remote Desktop Licensing Service if is not required.** If you no longer need this service on your system, consider disabling it as a security best practice. Disabling unused and unneeded services helps reduce your exposure to security vulnerabilities.

**What security feature is bypassed with this vulnerability?** The RDP Gateway protocol is enforcing the usage of Datagram Transport Layer Security (DTLS) version 1.0, which is a deprecated (RFC 8996) protocol with known vulnerabilities. An attacker with a machine-in-the-middle (MitM) position who successfully exploited this vulnerability could compromise the confidentiality and integrity of data when the targeted user connects to a trusted server.

**What security feature is being bypassed?** An attacker with a machine-in-the-middle (MitM) position who successfully exploited this vulnerability could bypass the certificate validation performed when a targeted user connects to a trusted server.

**What kind of security feature could be bypassed by successfully exploiting this vulnerability?** An attacker who successfully exploited the vulnerability could bypass certificate or private key authentication when establishing a remote desktop protocol session.
