"The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2014:0770 advisory.

    The foreman-proxy package provides a RESTful API to manage DNS, DHCP, TFTP,
    and Puppet settings, and can be used as part of Foreman.

    A shell command injection flaw was found in the way foreman-proxy verified
    URLs in the TFTP module. A remote attacker could use this flaw to execute
    arbitrary shell commands on the system with the privileges of the user
    running foreman-proxy. (CVE-2014-0007)

    This issue was discovered by Lukas Zapletal of Red Hat.

    Note that for Red Hat Enterprise Linux OpenStack Platform 3.0, Foreman was
    released as a Technology Preview. More information about Red Hat Technology
    Previews is available at
    https://access.redhat.com/site/support/offerings/techpreview/

    All foreman-proxy users are advised to upgrade to this updated package,
    which corrects 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.");
