Descriptions

An issue was discovered in SDCMS 1.6 with PHP 5.x. app/admin/controller/themecontroller.php uses a check_bad function in an attempt to block certain PHP functions such as eval, but does not prevent use of preg_replace 'e' calls, allowing users to execute arbitrary code by leveraging access to admin template management.

Se ha descubierto un problema en la versión 1.6 de SDCMS con PHP 5.x. app/admin/controller/themecontroller.php utiliza una función check_bad para intentar bloquear determinadas funciones PHP, como puede ser eval, pero no previene la utilización de llamadas preg_replace 'e', lo que permite que los usuarios ejecuten código arbitrario, aprovechando el acceso a la gestión de plantillas de administración.
