Описание
Traefik is an HTTP reverse proxy and load balancer. Prior to versions 2.11.43, 3.6.14, and 3.7.0-rc.2, there is an authentication bypass vulnerability in Traefik's ForwardAuth middleware when trustForwardHeader=false is configured and Traefik is deployed behind a trusted upstream proxy. This issue has been patched in versions 2.11.43, 3.6.14, and 3.7.0-rc.2.
A flaw was found in Traefik, an HTTP reverse proxy and load balancer. This authentication bypass vulnerability exists in Traefik's ForwardAuth middleware when the trustForwardHeader setting is configured as false and Traefik is deployed behind a trusted upstream proxy. A remote attacker could exploit this to bypass authentication, potentially gaining unauthorized access to protected resources.
Меры по смягчению последствий
To mitigate this issue, ensure that the trustForwardHeader setting in Traefik's ForwardAuth middleware is not explicitly configured as false unless absolutely necessary. If Traefik is deployed behind a trusted upstream proxy, review the configuration to ensure that trustForwardHeader is either set to true or omitted, allowing Traefik to correctly process forwarded headers for authentication. If this configuration is modified, a restart or reload of the Traefik service may be required for the changes to take effect.
