PHP-Charts v1.0 contains a PHP code execution vulnerability in wizard/url.php, where user-supplied GET parameter names are passed directly to eval() without sanitization. A remote attacker can exploit this flaw by crafting a request that injects arbitrary PHP code, resulting in command execution under the web server's context. The vulnerability allows unauthenticated attackers to execute system-level commands via base64-encoded payloads embedded in parameter names, leading to full compromise of the host system.
The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes code syntax before using the input in a dynamic evaluation call (e.g. "eval").
