CVE-2020-3255
Estado: ModificadaAlta (7.5)—
A vulnerability in the packet processing functionality of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to inefficient memory management. An attacker could exploit this vulnerability by sending a high rate of IPv4 or IPv6 traffic through an affected device. This traffic would need to match a configured block action in an access control policy.
Leer descripción completaMostrar menos
An exploit could allow the attacker to cause a memory exhaustion condition on the affected device, which would result in a DoS for traffic transiting the device, as well as sluggish performance of the management interface. Once the flood is stopped, performance should return to previous states.
CVSS

"value": "Una vulnerabilidad en la funcionalidad de procesamiento de paquetes del Cisco Firepower Threat Defense (FTD) Software, podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) sobre un dispositivo afectado. La vulnerabilidad es debido a una administración ineficiente de la memoria. Un atacante podría explotar esta vulnerabilidad mediante el envío de una alta tasa de tráfico IPv4 o IPv6 a través de un dispositivo afectado. Este tráfico necesitaría coincidir con una acción de bloqueo configurada en una política de control de acceso. Una explotación podría permitir a un atacante causar una condición de agotamiento de la memoria en el dispositivo afectado, lo que resultaría en una DoS para el tráfico que transita el dispositivo, así como un rendimiento lento de la interfaz de administración. Una vez que se detiene la inundación, el rendimiento debe volver a los estados anteriores."
