      "value": "An authentication-bypass issue was discovered on D-Link DAP-1522 devices 1.4x before 1.10b04Beta02. There exist a few pages that are directly accessible by any unauthorized user, e.g., logout.php and login.php. This occurs because of checking the value of NO_NEED_AUTH. If the value of NO_NEED_AUTH is 1, the user has direct access to the webpage without any authentication. By appending a query string NO_NEED_AUTH with the value of 1 to any protected URL, any unauthorized user can access the application directly, as demonstrated by bsc_lan.php?NO_NEED_AUTH=1."

Se presentan algunas p\u00e1ginas que son directamente accesibles por cualquier usuario no autorizado, por ejemplo, logout.php y login.php. Esto ocurre debido a una comprobaci\u00f3n del valor de NO_NEED_AUTH. Si el valor de NO_NEED_AUTH es 1, el usuario tiene acceso directo a la p\u00e1gina web sin ninguna autenticaci\u00f3n. Al agregar una cadena de consulta de NO_NEED_AUTH con el valor de 1 en cualquier URL protegida, cualquier usuario no autorizado puede acceder a la aplicaci\u00f3n directamente, como es demostrado por bsc_lan.php?NO_NEED_AUTH=1"
