critical Tenable Cloud Security Plugin ID 434623

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Traefik (pronounced traffic) is an HTTP reverse proxy and load balancer. In versions prior to 2.11.24,
3.3.6, and 3.4.0-rc2. There is a potential vulnerability in Traefik managing the requests using a
PathPrefix, Path or PathRegex matcher. When Traefik is configured to route the requests to a backend using
a matcher based on the path, if the URL contains a /../ in its path, it’s possible to target a backend,
exposed using another router, by-passing the middlewares chain. This issue has been patched in versions
2.11.24, 3.3.6, and 3.4.0-rc2. A workaround involves adding a `PathRegexp` rule to the matcher to prevent
matching a route with a `/../` in the path. (CVE-2025-32431)
