FreeBSD : traefik -- Path traversal vulnerability (67dd7a9e-3cd8-11f0-b601-5404a68ad561)

medium Nessus Plugin ID 237557

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 67dd7a9e-3cd8-11f0-b601-5404a68ad561 advisory.

 The traefik project reports:
 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 URL encoded string in its path, it's possible to target a backend, exposed using another router, by-passing the middlewares chain.

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
