The remote Redhat Enterprise Linux 7 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2019:1728 advisory.
This Python package provides a dynamic vendordata plugin for the OpenStack nova metadata service to manage host instantiation in an IPA server.
Security Fix:
* python-novajoin: novajoin API lacks access control (CVE-2019-10138)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page listed in the References section.
Bug Fix(es):
* TLS-Everywhere - missing folder /var/lib/novajoin (BZ#1608273)
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.
