Name of the Vulnerable Software and Affected Versions kube-rbac-proxy versions prior to 0.4.1

Description The issue allows for the use of insecure ciphers and TLS 1.0, as the kube-rbac-proxy container does not honor TLS configurations. This could enable an attacker to target traffic sent over a TLS connection with a weak configuration and potentially break the encryption.

Recommendations For versions prior to 0.4.1, update to version 0.4.1 or later to resolve the issue. As a temporary workaround, consider disabling the use of insecure ciphers and TLS 1.0 in the TLS configuration until a patch is available. Restrict access to the kube-rbac-proxy container to minimize the risk of exploitation.
