"The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2016:2091 advisory.

    Red Hat CloudForms Management Engine delivers the insight, control, and
    automation needed to address the challenges of managing virtual
    environments. CloudForms Management Engine is built on Ruby on Rails, a
    model-view-controller (MVC) framework for web application development.
    Action Pack implements the controller and the view components.

    Security Fix(es):

    * CloudForms did not properly apply permissions controls to
    VM IDs passed by users. A remote, authenticated attacker could
    use this flaw to execute arbitrary VMs on systems managed by
    CloudForms if they know the ID of the VM. (CVE-2016-7071)

    This update also fixes several bugs. Documentation for these changes
    is available in the Release Notes linked to in the References section.

    All CFME users are advised to upgrade to these updated packages, which
    correct these issues and add these enhancements.

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.");
