CVE-2024-45410 Â (opens in a new tab)How to fix?
Upgrade github.com/traefik/traefik/v2/pkg/middlewares/forwardedheaders to version 2.11.9 or higher.
Overview
Affected versions of this package are vulnerable to Insufficient Verification of Data Authenticity through the manipulation of HTTP headers in the HTTP/1.1 protocol. An attacker can alter or remove headers such as X-Forwarded-Host, potentially leading to security implications like access control bypass or data leakage by specifying these headers as hop-by-hop in the Connection header.
Note:
This is only exploitable if the backend application trusts the headers set by Traefik without revalidating them.
