    descriptionAccording to its self-reported version number, the Puppet Enterprise 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)

    descriptionPuppet reports : Puppet Enterprise previously included a puppet-agent MCollective plugin that allowed you to pass the `--server` argument to MCollective. This insecure argument enabled remote code execution via connection to an untrusted host. The puppet-agent MCollective version included in PE 2016.2.1, this option is disabled by default.
