#Windows Secure Channel

**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** The attacker must inject themselves into the logical network path between the target and the resource requested by the victim to read or modify network communications. This is called a machine-in-the-middle (MITM) attack.

**Does this vulnerability affect all versions of TLS?** No. Only those devices running TLS 1.3 are affected. For more information on supported TLS implementations please visit: https://learn.microsoft.com/en-us/windows/win32/secauthn/protocols-in-tls-ssl--schannel-ssp-
