Descriptions
A vulnerability in the sftunnel functionality of Cisco Firepower Management Center (FMC) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to obtain the device registration hash. The vulnerability is due to insufficient sftunnel negotiation protection during initial device registration. An attacker in a man-in-the-middle position could exploit this vulnerability by intercepting a specific flow of the sftunnel communication between an FMC device and an FTD device. A successful exploit could allow the attacker to decrypt and modify the sftunnel communication between FMC and FTD devices, allowing the attacker to modify configuration data sent from an FMC device to an FTD device or alert data sent from an FTD device to an FMC device.
Una vulnerabilidad en la funcionalidad sftunnel de Cisco Firepower Management Center (FMC) Software y Cisco Firepower Threat Defense (FTD) Software, podría permitir a un atacante remoto no autenticado obtener el hash de registro del dispositivo. La vulnerabilidad es debido a una protección de negociación de sftunnel insuficiente durante el registro inicial del dispositivo. Un atacante en una posición man-in-the-middle podría explotar esta vulnerabilidad al interceptar un flujo específico de la comunicación sftunnel entre un dispositivo FMC y un dispositivo FTD. Una explotación con éxito podría permitir a un atacante descifrar y modificar la comunicación sftunnel entre los dispositivos FMC y FTD, permitiendo a un atacante modificar los datos de configuración enviados desde un dispositivo FMC hacia un dispositivo FTD o los datos de alerta enviados desde un dispositivo FTD a un dispositivo FMC
