Descriptions
A vulnerability in the VPN System Logging functionality for Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a memory leak that can deplete system memory over time, which can cause unexpected system behaviors or device crashes. The vulnerability is due to the system memory not being properly freed for a VPN System Logging event generated when a VPN session is created or deleted. An attacker could exploit this vulnerability by repeatedly creating or deleting a VPN tunnel connection, which could leak a small amount of system memory for each logging event. A successful exploit could allow the attacker to cause system memory depletion, which can lead to a systemwide denial of service (DoS) condition. The attacker does not have any control of whether VPN System Logging is configured or not on the device, but it is enabled by default.
Una vulnerabilidad en la funcionalidad VPN System Logging para el Cisco Firepower Threat Defense (FTD) Software, podría permitir a un atacante remoto no autenticado causar una pérdida de memoria que puede agotar la memoria del sistema con el tiempo, lo que puede causar comportamientos inesperados del sistema o bloqueos del dispositivo. La vulnerabilidad es debido a que la memoria del sistema no está siendo liberada apropiadamente para un evento de la VPN System Logging cuando es creada o eliminada una sesión VPN. Un atacante podría explotar esta vulnerabilidad creando o eliminando repetidamente una conexión de túnel VPN, lo cual podría filtrar una pequeña cantidad de memoria del sistema para cada evento de registro. Una explotación con éxito podría permitir a un atacante causar el agotamiento de la memoria del sistema, lo que puede conllevar a una condición de denegación de servicio (DoS) en todo el sistema. El atacante no posee ningún control sobre si VPN System Logging está configurado o no en el dispositivo, pero está habilitado por defecto.
