NVD Description

Note: Versions mentioned in the description apply only to the upstream freerdp2 package and not the freerdp2 package as distributed by Debian. See How to fix? for Debian:12 relevant fixed versions and status.

FreeRDP 3.0.0 before 3.32.0 allows HTTP header injection in its proxy because a lone LF in the target portion of a routing token (Cookie: msts=) is not rejected and is written by http_proxy_connect into the CONNECT request line and Host header. A remote unauthenticated RDP client connecting to a proxy using FixedTarget=false and an upstream HTTP proxy can alter HTTP request/header framing at that upstream proxy.
