Name of the Vulnerable Software and Affected Versions
Puppet Server (affected versions not specified)
Puppet Enterprise (affected versions not specified)
Description
Incorrect authorization occurs during certificate-name matching in trapperkeeper-authorization. A client possessing a CA-signed certificate with a name that extends or shortens an authorized hostname can be authorized as that host. This flaw allows for node impersonation and, specifically within Puppet Enterprise, provides access to certificate-authority administration and remote command execution on managed nodes. Exploitation depends on the certificate authority issuing a certificate with a colliding name via approval or autosign.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
