io.netty/netty-codec-http: Netty RtspDecoder Method-Token Smuggling via Trailing Control Byte

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. Th...
