原文の説明
取得元が公開している説明をそのまま載せています (多くは英語)。
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.
