Description

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.
