CVE-2024-45410 Information

Description

Traefik is a golang Cloud Native Application Proxy. When a HTTP request is processed by Traefik certain HTTP headers such as X-Forwarded-Host or X-Forwarded-Port are added by Traefik before the request is routed to the application. For a HTTP client it should not be possible to remove or modify these headers. Since the application trusts the value of these headers security implications might arise if they can be modified. For HTTP/1.1 however it was found that some of theses custom headers can indeed be removed and in certain cases manipulated. The attack relies on the HTTP/1.1 behavior that headers can be defined as hop-by-hop via the HTTP Connection header. This issue has been addressed in release versions 2.11.9 and 3.1.3. Users are advised to upgrade. There are no known workarounds for this vulnerability.
