Description

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

Versions of Puppet Enterprise prior to 2016.4.5 or 2017.2.1 failed to mark MCollective server private keys as sensitive (a feature added in Puppet 4.6), so key values could be logged and stored in PuppetDB. These releases use the sensitive data type to ensure this won't happen anymore.

Mitigation
Install update from vendor's website.
