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.\n\nRed Hat Certificate System 10.0 as well as Red Hat Enterprise Linux 8\u0027s 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.",
