NVD Description

Note: Versions mentioned in the description apply only to the upstream netty-tcnative package and not the netty-tcnative package as distributed by SLES. See How to fix? for SLES:15.6 relevant fixed versions and status.

A flaw was found in Netty RtspDecoder. The RtspMethods.valueOf() function incorrectly strips trailing control bytes from method tokens in Real-Time Streaming Protocol (RTSP) requests. A remote attacker can exploit this by sending a specially crafted RTSP request, leading to method-token smuggling. This vulnerability allows an attacker to bypass method-based access controls and can also be used to launder malicious requests through Netty-based RTSP proxies, making them appear legitimate to backend systems.
