Descriptions

MyBB before 1.8.29 allows Remote Code Injection by an admin with the "Can manage settings?" permission. The Admin CP's Settings management module does not validate setting types correctly on insertion and update, making it possible to add settings of supported type "php" with PHP code, executed on Change Settings pages.

MyBB versiones anteriores a 1.8.29, permite una Inyección de Código Remota por parte de un administrador con el permiso "Can manage settings?". El módulo de administración de configuraciones del CP del Administrador no comprueba correctamente los tipos de configuraciones al insertarlas y actualizarlas, haciendo posible añadir configuraciones del tipo "php" con código PHP, ejecutado en las páginas de cambio de configuraciones
