Descriptions

Traefik is an open source HTTP reverse proxy and load balancer. In affected versions there is a potential vulnerability in Traefik managing 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. Users are advised to upgrade to version 2.9.6. Users unable to upgrade should check their logs to detect the error messages and fix your TLS options.

Traefik es un equilibrador de carga y proxy inverso HTTP de código abierto. En las versiones afectadas existe una vulnerabilidad potencial en Traefik que gestiona las conexiones TLS. Un router configurado con una TLSOption mal formateada se expone con una TLSOption vacía. Por ejemplo, una ruta asegurada mediante una conexión mTLS configurada con un archivo CA incorrecto queda expuesta sin verificar los certificados del cliente. Se recomienda a los usuarios que actualicen a la versión 2.9.6. Los usuarios que no puedan actualizar deben verificar sus registros para detectar los mensajes de error y corregir sus opciones de TLS.
