Name of the Vulnerable Software and Affected Versions Netty versions 4.1.124.Final Netty versions 4.2.0.Alpha3 through 4.2.4.Final

Description Netty is an asynchronous event-driven network application framework for development of maintainable high performance protocol servers and clients. Netty incorrectly accepts standalone newline characters (LF) as a chunk-size line terminator, regardless of a preceding carriage return (CR), instead of requiring CRLF per HTTP/1.1 standards. When combined with reverse proxies that parse LF differently, attackers can craft requests that the proxy sees as one request but Netty processes as two, enabling request smuggling attacks.

Recommendations Netty version 4.1.125.Final Netty version 4.2.5.Final
