Descriptions
A vulnerability in the WebVPN login process of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause increased CPU utilization on an affected device. The vulnerability is due to excessive processing load for existing WebVPN login operations. An attacker could exploit this vulnerability by sending multiple WebVPN login requests to the device. A successful exploit could allow the attacker to increase CPU load on the device, resulting in a denial of service (DoS) condition.
Una vulnerabilidad en el proceso de inicio de sesión (login) en la WebVPN de los software Adaptive Security Appliance (ASA) y Firepower Threat Defense (FTD) de Cisco, podría permitir que un atacante remoto no identificado cause un aumento en la utilización de la CPU en un dispositivo afectado. La vulnerabilidad es debido a una carga de procesamiento excesiva para las operaciones de inicio de sesión de WebVPN existentes. Un atacante podría aprovechar esta vulnerabilidad enviando múltiples peticiones de inicio de sesión desde WebVPN al dispositivo. Una operación con éxito podría permitir al atacante incrementar la carga de la CPU en el dispositivo, dando como resultado una condición de Denegación de Servicio (DoS).
