"The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2017:3484 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.

    CloudForms Management Engine Appliance.

    CloudForms Management Engine Gemset.

    Security Fix(es):

    * CloudForms lacks RBAC controls on certain methods in the rails application portion of CloudForms. An
    attacker with access could use a variety of methods within the rails applications portion of CloudForms to
    escalate privileges. (CVE-2017-2664)

    This issue was discovered by Libor Pichler (Red Hat) and Martin Povolny (Red Hat).

    Additional Changes:

    This update also fixes several bugs and adds various enhancements. Documentation for these changes is
    available from the Release Notes document linked to in the References section.

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.");
