lib/puppet/network/authstore.rb in Puppet before 2.7.18, and Puppet Enterprise before 2.5.2, supports use of IP addresses in certnames without warning of potential risks, which might allow remote attackers to spoof an agent by acquiring a previously used IP address.
Weakness
When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
