Unauthenticated code execution via template expressions
Published Apr 28, 2025 · Updated Apr 28, 2025
Server-side template injection in IPW Systems Metazo 8.1.3 and earlier allows remote attackers to execute attacker-controlled code. The smartyValidator.php script processes attacker-supplied expressions as server-side Smarty template syntax without neutralizing the directives. No authentication or user interaction is required, and successful exploitation executes code on the Metazo server.
