The remote Redhat Enterprise Linux 6 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2018:2372 advisory.
Cobbler is a network install server. Cobbler supports PXE, virtualized installs, and re-installing existing Linux machines. Cobbler has a XMLRPC API for integration with other applications.
Security Fix(es):
* cobbler: CobblerXMLRPCInterface exports all its methods over XMLRPC (CVE-2018-10931)
For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.
This issue was discovered by Cedric Buissart (Red Hat).
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.
