"The remote host is running FortiOS prior to 4.3.16 or 5.x prior to
5.0.8. It is, therefore, affected by the following vulnerabilities :

  - A flaw exists within the FortiManager service when
    handling incoming requests. Using a specially crafted
    request, a remote attacker can exploit this to cause a
    denial of service or possibly execute arbitrary code.
    (CVE-2014-2216)

  - A flaw exists within the FortiManager communications
    protocol that allows a man-in-the-middle attacker,
    using an anonymous cipher suite, to acquire sensitive
    information or otherwise impact host communications.
