CVE-2012-3867

Impact: Low
Public: 2012-07-10
Bugzilla: 839158: CVE-2012-3867 puppet: insufficient validation of agent names in CN of SSL certificate requests

Details

The MITRE CVE dictionary describes this issue as:

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.
