"The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2015:1929 advisory.

    Ironic provides bare metal provisioning for OpenStack nodes.

    It was discovered that enabling debug mode in openstack-ironic-discoverd
    also enables debug mode in the underlying Flask framework. If errors are
    encountered while Flask is in debug mode, a user experiencing an error may
    be able to access the debug console (effectively, a command shell).
    (CVE-2015-5306)

    All openstack-ironic-discoverd users are advised to upgrade to these
    updated packages, which correct this issue.

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.");
