According to its self-reported version number, the Puppet Enterprise install on the remote host is a version prior to 3.1.0. As a result, it is reportedly affected by multiple vulnerabilities :
An error exists related to the Fiddle and DL modules, ‘$SAFE’ level verification and object handling that could allow an attacker to modify system calls.
(CVE-2013-2065)
A remote code execution vulnerability exists that is triggered when handling a YAML report. This could allow a remote attacker to execute arbitrary code.
(CVE-2013-4957)
A console account brute-force vulnerability exists that could allow an attacker to brute-force a known user’s password. (CVE-2013-4965)
A RubyGems algorithmic complexity denial of service vulnerability exists that could allow an attacker to cause a denial of service through CPU consumption.
(CVE-2013-4287)
