Status: ModifiedLow (2.6)—

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.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
