TencentOS Server 3: tomcat (TSSA-2024:0237)

high Nessus Plugin ID 239000

Synopsis

The remote TencentOS Server 3 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:0237 advisory.

 Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

 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.

 CVE-2024-24549:
 A vulnerability was found in the Tomcat package due to its handling of HTTP/2 requests. Specifically, when an HTTP/2 request surpasses the predetermined limits for headers configured within the server, the associated HTTP/2 stream isn't reset immediately. Instead, the reset action occurs only after all the headers within the request have been processed. This lapse in resetting the stream exposes the system to potential risks, as it allows malicious actors to exploit the delay in stream reset to carry out various attacks, such as header manipulation or resource exhaustion.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
