Parameter Value
CVSS 8.6 (HIGH)
Type CWE-269 (Improper Privilege Management), CWE-78 (OS Command Injection), CWE-20 (Improper Input Validation)
Vendor Puppet
Public PoC No

Affected versions of Puppet Enterprise contain a command injection vulnerability in the handling of the java_keystore_passwd parameter. 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.
