Firepower Threat Defense (FTD) Software para los firewalls Cisco Firepower 1000 Series, podría permitir a un atacante remoto no autenticado obtener acceso a información confidencial. La vulnerabilidad es debido a una implementación inapropiada de contramedidas contra el ataque Bleichenbacher para conjuntos de cifrado que dependen de RSA para el intercambio de claves. Un atacante podría explotar esta vulnerabilidad mediante el envío de mensajes TLS diseñados hacia el dispositivo, que actuaría como un oráculo y permitiría a un atacante conducir un ataque de texto cifrado elegido. Una explotación con éxito podría permitir a un atacante realizar operaciones criptoanalíticas que podrían habilitar el descifrado de sesiones TLS capturadas previamente en el dispositivo afectado. Para aprovechar esta vulnerabilidad, un atacante necesita ser capaz de realizar ambas de las siguientes acciones: Capturar el tráfico TLS que esta en transito entre clientes y el dispositivo afectado que
