"The remote Redhat Enterprise Linux 7 host has a package installed that is affected by a vulnerability as referenced in
the RHSA-2016:2116 advisory.

    OpenStack's File Share Service (manila) provides the means to easily provision shared file systems that
    can be consumed by multiple instances. These shared file systems are provisioned from pre-existing, back-
    end volumes. The UI component provides the dashboard plugin for the service.

    Security Fix(es):

    * A cross-site scripting flaw was discovered in openstack-manila-ui's Metadata field contained in its
    Create Share form. A user could inject malicious HTML/JavaScript code that would then be reflected in
    the Shares overview. Remote, authenticated, but unprivileged users could exploit this vulnerability to
    steal session cookies and escalate their privileges. (CVE-2016-6519)

    Red Hat would like to thank SUSE for reporting this issue. SUSE acknowledges Niklaus Schiess as the
    original reporter.

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
