Plume CMS 1.0.2 (register_globals enabled)
Craft malicious URL with arbitrary file path in _PX_config[manager_path] parameter to include and execute remote PHP files
Disable register_globals in php.ini, update Plume CMS to patched version, sanitize and validate all user input file paths
If register_globals is ON and prepend.php file is found, the system is vulnerable; patched versions or register_globals disabled means vulnerability is mitigated
