Summary
Etcd Gateway TLS endpoint validation only confirms TCP reachability
Details

Vulnerability type

Cryptography

Workarounds

Refer to the gateway documentation. The vulnerability was spotted due to unclear documentation of how the gateway handles endpoints validation.

Detail

Secure endpoint validation is performed by the etcd gateway start command when the --discovery-srv flag is enabled. However, as currently implemented, it only validates TCP reachability, effectively allowing connections to an endpoint that doesn't accept TLS connections through the HTTPS URL. The auditors has noted that appropriate documentation of this validation functionality plus deprecation of this misleading functionality is an acceptable path forward.
