Descriptions

The request handling functions in web management interface of Brocade Fabric OS versions before v9.0.1a, v8.2.3a, and v7.4.2h do not properly handle malformed user input, resulting in a service crash. An authenticated attacker could use this weakness to cause the FOS HTTP application handler to crash, requiring a reboot.

Las funciones de manejo de solicitudes en la interfaz de administración web de las versiones del sistema operativo Brocade Fabric anteriores a las versiones v9.0.1a, v8.2.3a y v7.4.2h no manejan adecuadamente la entrada de usuario con formato incorrecto, lo que resulta en un bloqueo del servicio. Un atacante autenticado podría usar esta debilidad para hacer que el controlador de la aplicación HTTP de FOS se bloquee, requiriendo un reinicio.
