Miggo AIRoot Cause Analysis
The vulnerability occurs in the 'restartcheck' module where process names are used unsafely in shell commands. The code uses 'subprocess.Popen' with 'shell=True' and concatenates the 'package' variable (derived from process names) into the command string without proper sanitization. This allows attackers to inject arbitrary commands via specially crafted process names. The exploit references and SaltStack's own patching notes confirm this function as the attack vector.
