CyberRota Analysis
AI-GeneratedThe BasicAuth middleware in Traefik versions 3.6.11 to 3.6.25 and 3.7.10 is vulnerable due to improper handling of concurrent password checks, which can allow an attacker with valid credentials to authenticate as an unconfigured username. This could lead to unauthorized access under certain configurations where headerField trusts the forwarded identity. Organizations using affected versions of Traefik should prioritize updating to versions 3.6.25 or 3.7.10 to mitigate this risk.

Original NVD Description
Traefik is an open source HTTP reverse proxy and load balancer. From 3.6.11 until 3.6.25 and 3.7.10, Traefik's BasicAuth middleware in pkg/middlewares/auth/basic_auth.go deduplicates concurrent password checks with a singleflight key built from the delimiter-free concatenation of password and secret, allowing an attacker who has a valid credential and the stored hash to authenticate as an unconfigured username when headerField trusts the forwarded identity. This issue is fixed in 3.6.25 and 3.7.10.
