Apache Tomcat WebSocket Infinite Loop Denial of Service

This strike exploits an infinite loop vulnerability in the WebSocket module of Apache Tomcat. The vulnerability is caused by improper validations of the extended payload length. A remote, unauthenticated attacker can send crafted WebSocket requests to the server resulting in each of the worker nodes entering an infinite loop; multiple such requests could lead to a denial of service. Note: The strike in one-arm mode uses a specific path "/examples/websocket/echoAnnotation" to perform the exploitation. This path points to the WebSocket examples included with Tomcat.
