A partir de la versi\u00f3n 3.4.0 y anterior a la versi\u00f3n 3.4.2, existe una vulnerabilidad de falsificaci\u00f3n de petici\u00f3n en sitios cruzados (CSRF) en la configuraci\u00f3n del filtro de la aplicaci\u00f3n. El mecanismo de protecci\u00f3n CSRF fue deshabilitado expl\u00edcitamente, permitiendo que la aplicaci\u00f3n procese peticiones que cambian el estado (POST) sin verificar un token CSRF v\u00e1lido. Un atacante remoto no autenticado puede explotar esto al alojar una p\u00e1gina web maliciosa. Si un administrador con sesi\u00f3n iniciada visita esta p\u00e1gina, su navegador es forzado a enviar peticiones no autorizadas a la aplicaci\u00f3n. Un exploit exitoso permite al atacante crear silenciosamente una nueva cuenta de Administrador con privilegios completos, lo que lleva a una toma de control completa del sistema y a la p\u00e9rdida de confidencialidad, integridad y disponibilidad. La vulnerabilidad ha sido parcheada en la versi\u00f3n 3.4.2. La correcci\u00f3n vuelve a habilitar el filtro CSRF en 'app/Config/Filters.php' y resuelve las condiciones de carrera AJAX asociadas ajustando la configuraci\u00f3n de regeneraci\u00f3n de tokens. Como soluci\u00f3n alternativa, los administradores pueden volver a habilitar manualmente el filtro CSRF en 'app/Config/Filters.php' descomentando la l\u00ednea de protecci\u00f3n.
