CVE-2017-9466

Estado: ModificadaCrítica (9.8)—

El httpd ejecutable en el router TP-Link WR841N V8, en versiones anteriores a la TL-WR841N(UN)_V8_170210, contiene un fallo de diseño en el uso de DES para el cifrado en bloque. Esto resultó en un control de acceso incorrecto, lo que permitía que atacantes obtuviesen acceso de lectura-escritura a las opciones del sistema mediante el servicio de configuración del router protegido tddp mediante las interfaces LAN y Ath0 (Wi-Fi).
