Descriptions
Denial of Service via incomplete cleanup vulnerability in Apache Tomcat. It was possible for WebSocket clients to keep WebSocket connections open leading to increased resource consumption.This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.0-M16, from 10.1.0-M1 through 10.1.18, from 9.0.0-M1 through 9.0.85, from 8.5.0 through 8.5.98.
Users are recommended to upgrade to version 11.0.0-M17, 10.1.19, 9.0.86 or 8.5.99 which fix the issue.

A denial of service (DoS) vulnerability present in the Apache Tomcat package arises from an incomplete cleanup process. Specifically, WebSocket clients can perpetuate WebSocket connections without proper termination, thereby causing a sustained drain on system resources. This vulnerability facilitates the exploitation of Apache Tomcat servers, leading to a scenario where excessive resource consumption occurs due to the prolonged existence of these open WebSocket connections. As a consequence, the server's performance may degrade significantly, resulting in potential service disruption or unresponsiveness.
