Authentication
Refer to the gateway documentation. The vulnerability was spotted due to unclear documentation of how the gateway handles endpoints validation.
The gateway only authenticates endpoints detected from DNS SRV records, and it only authenticates the detected endpoints once. Therefore, if an endpoint changes its authentication settings, the gateway will continue to assume the endpoint is still authenticated. The auditors has noted that appropriate documentation of this validation functionality plus deprecation of this misleading functionality is an acceptable path forward.
