Puppet Enterprise 2015.3.3 and 2016.x before 2016.4.0, and Puppet Agent 1.3.6 through 1.7.0 allow remote attackers to bypass a host whitelist protection mechanism and execute arbitrary code on Puppet nodes via vectors related to command validation, aka "Puppet Execution Protocol (PXP) Command Whitelist Validation Vulnerability."

The console in Puppet Enterprise 2015.x and 2016.x prior to 2016.4.0 includes unsafe string reads that potentially allows for remote code execution on the console node.
