The remote Redhat Enterprise Linux 8 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2022:8791 advisory.
Red Hat JBoss Enterprise Application Platform 7 is a platform for Java applications based on the WildFly application runtime. This release of Red Hat JBoss Enterprise Application Platform 7.4.8 serves as a replacement for Red Hat JBoss Enterprise Application Platform 7.4.7, and includes bug fixes and enhancements. See the Red Hat JBoss Enterprise Application Platform 7.4.8 Release Notes for information about the most significant bug fixes and enhancements included in this release.
Security Fix(es):
* undertow: DoS can be achieved as Undertow server waits for the LAST_CHUNK forever for EJB invocations (CVE-2022-2764)
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.
