Name of the Vulnerable Software and Affected Versions NeuVector (affected versions not specified)

Description NeuVector supports login authentication through OpenID Connect. The TLS verification, which confirms the remote server’s authenticity and integrity, is not enforced by default for OpenID Connect. This could expose the system to man-in-the-middle (MITM) attacks. A man-in-the-middle attack involves an attacker intercepting communication between two parties without their knowledge.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
