CVE-2024-23672

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.

This Denial of Service (DoS) vulnerability within the Apache Tomcat package represents an Important severity issue due to its potential to significantly impact system availability and performance. By allowing WebSocket clients to maintain open connections without proper cleanup, the vulnerability facilitates the sustained consumption of server resources. This exploitation results in increased CPU, memory, and network utilization, ultimately leading to server degradation or unresponsiveness. The inability to terminate these lingering connections efficiently exacerbates the severity of the issue, as it enables attackers to exploit limited resources over an extended period, amplifying the impact of the attack.

Red Hat Certificate System 10.0 as well as Red Hat Enterprise Linux 8's Identity Management, are using a vulnerable version of Tomcat, bundled into the pki-servlet-engine component. However, there are no entry point for WebSockets, and thus it is not possible to trigger the flaw in a supported setup.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
