GMS-2022-8053: Traefik routes exposed with an empty TLSOption

December 8, 2022

There is a potential vulnerability in Traefik managing the TLS connections. A router configured with a not well-formatted TLSOption is exposed with an empty TLSOption. For instance, a route secured using an mTLS connection set with a wrong CA file is exposed without verifying the client certificates.
