The Netty project is an effort to provide an asynchronous event-driven
network application framework and tools for rapid development of
maintainable high performance and high scalability protocol servers and
clients. In other words, Netty is a NIO client server framework which
enables quick and easy development of network applications such as protocol
servers and clients. It greatly simplifies and streamlines network
programming such as TCP and UDP socket server.
Path to vulnerable library: /home/wss-scanner/.m2/repository/io/netty/netty/3.4.0.Final/netty-3.4.0.Final.jar,/home/wss-scanner/.m2/repository/io/netty/netty/3.4.0.Final/netty-3.4.0.Final.jar,/home/wss-scanner/.m2/repository/io/netty/netty/3.4.0.Final/netty-3.4.0.Final.jar
HttpObjectDecoder.java in Netty before 4.1.44 allows an HTTP header that lacks a colon, which might be interpreted as a separate header with an incorrect syntax, or might be interpreted as an "invalid fold."
