lib/puppet/ssl/certificate_authority.rb in Puppet before 2.6.17 and 2.7.x before 2.7.18, and Puppet Enterprise before 2.5.2, does not properly restrict the characters in the Common Name field of a Certificate Signing Request (CSR), which makes it easier for user-assisted remote attackers to trick administrators into signing a crafted agent certificate via ANSI control sequences.

Security readout for executives and security teams

This Puppet flaw let a remote attacker submit a misleading certificate request that could trick an administrator into approving the wrong agent certificate. It depends on human approval, but Puppet certificates grant trust inside configuration management, so impact can be material in environments still running these obsolete versions. Exposure is likely limited to Puppet CA deployments running Puppet before 2.6.17, Puppet 2.7.x before 2.7.18, or Puppet Enterprise before 2.5.2, especially where administrators manually review and sign agent CSRs. Prioritize if Puppet manages production infrastructure or if legacy Puppet CA servers remain active. The flaw is old and user-assisted, but a wrongly trusted Puppet agent can create serious configuration-management risk. Mitigation focus: Upgrade Puppet to 2.6.17, 2.7.18, or later as applicable.; Upgrade Puppet Enterprise to 2.5.2 or later as applicable.; Apply relevant Debian, Ubuntu, SUSE, or vendor package advisories..
