On August 12th, 2022, many of Keysight’s Network Test, Network Visibility, & Edge to Core (NAS/formerly Ixia) products will migrate to a new license structure.
CRITICAL: If you perform licensing operations after August 12th, 2022, without upgrading the licensing software to the latest version, licenses may not register properly, and some features may be missing. This could impact testing and result in downtime.

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.
