Traefik vulnerable to Open Redirect via handling of X-Forwarded-Prefix header

6.1 / 10
Medium
Network High None Required Changed None High None

Summary

There exists a potential open redirect vulnerability in Traefik's handling of the X-Forwarded-Prefix header. Active Exploitation of this issue is unlikely as it would require active header injection, however the Traefik team addressed this issue nonetheless to prevent abuse in e.g. cache poisoning scenarios.

Details

The Traefik API dashboard component doesn't validate that the value of the header X-Forwarded-Prefix is a site relative path and will redirect to any header provided URI.

e.g.

$ curl --header 'Host:traefik.localhost' --header 'X-Forwarded-Prefix:https://example.org' 'http://localhost:8081' <a href="https://example.org/dashboard/">Found</a>.`

Impact

A successful exploitation of an open redirect can be used to entice victims to disclose sensitive information.

Workarounds

By using the headers middleware, the request header X-Forwarded-Prefix value can be overridden by the value . (dot)
