## Technical details

An improper neutralization of special elements in OS command construction (CWE-78) in the AutomatedProvisioner component fails to sanitize the salt minion ID parameter before passing it to an OS command. A remote attacker can exploit this via network without authentication to achieve remote code execution as root by injecting shell metacharacters in the minion ID field.
