The remote Redhat Enterprise Linux 7 / 8 / 9 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2023:5783 advisory.

Red Hat JBoss Web Server is a fully integrated and certified set of components for hosting Java web     applications. It is comprised of the Apache Tomcat Servlet container, JBoss HTTP Connector (mod_cluster),     the PicketLink Vault extension for Apache Tomcat, and the Tomcat Native library.

This release of Red Hat JBoss Web Server 5.7.5 serves as a replacement for Red Hat JBoss Web Server 5.7.4.
This release includes bug fixes, enhancements and component upgrades, which are documented in the Release     Notes, linked to in the References section.

Security Fix(es):

* tomcat: HTTP/2: Multiple HTTP/2 enabled web servers are vulnerable to a DDoS attack (Rapid Reset Attack)     (CVE-2023-44487)

A Red Hat Security Bulletin which addresses further details about this flaw is available in the References     section.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
