The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:2387 advisory.
The mod_jk module is a plugin for the Apache HTTP Server to connect it with the Apache Tomcat servlet engine.
The mod_proxy_cluster module is a plugin for the Apache HTTP Server that provides load-balancer functionality.
Security Fix(es):
* httpd: Apache Tomcat Connectors (mod_jk) Information Disclosure (CVE-2023-41081)
* mod_cluster/mod_proxy_cluster: Stored Cross site Scripting (CVE-2023-6710)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Additional Changes:
For detailed information on changes in this release, see the Red Hat Enterprise Linux 9.4 Release Notes linked from the References section.
Tenable has extracted the preceding description block directly from the Red Hat Enterprise 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.
