Traefik routes exposed with an empty TLSOption


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.



Check the logs to detect the following error messages and fix your TLS options:

{"level":"error","msg":"invalid clientAuthType: RequireAndVerifyClientCert, CAFiles is required","routerName":"[email protected]"}
{"level":"error","msg":"invalid certificate(s) content","routerName":"[email protected]"}
{"level":"error","msg":"unknown client auth type \"FooClientAuthType\"","routerName":"[email protected]"}
{"level":"error","msg":"invalid CipherSuite: foobar","routerName":"[email protected]"}
{"level":"error","msg":"invalid CurveID in curvePreferences: foobar","routerName":"[email protected]"}
