application running on the remote host is version 
prior to 2016.2.1. It is, therefore, affected by the following 
vulnerabilities :

  - A remote code execution vulnerability exists in the mcollective
    puppet-agent plugin due to an insecure argument. An 
    unauthenticated, remote attacker can exploit this to 
    enable remote code execution .  (CVE-2015-7331)

  - A flaw exists in the Puppet Enterprise Console due to
    unsafe string processing that allows an authenticated,
    remote attacker to execute arbitrary code. (CVE-2016-2788)");
