Description

Affected versions of Puppet Enterprise contain a command injection vulnerability. An authenticated user with Puppet administrative privileges can inject arbitrary shell commands by providing a specially crafted value for this parameter, which is passed to a shell execution context without sufficient sanitization. Because the resulting commands are executed with root privileges, successful exploitation can lead to full compromise of the affected system. It affects Puppet Enterprise 2023.8.0 through 2023.8.10 and Puppet Enterprise 2025.0.0 through 2025.11.2. This has been resolved in Puppet Enterprise 2023.8.11 and Puppet Enterprise 2025.11.3.

Affected products

Perforce Software Puppet Enterprise: from 2023.8.0 through 2023.8.10; from 2025.0.0 through 2025.11.2
