Descriptions

A vulnerability in the Application Visibility and Control (AVC-FNF) feature of Cisco IOS XE Software for Cisco Catalyst 9800 Series Wireless Controllers could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient packet verification for traffic inspected by the AVC feature. An attacker could exploit this vulnerability by sending crafted packets from the wired network to a wireless client, resulting in the crafted packets being processed by the wireless controller. A successful exploit could allow the attacker to cause a crash and reload of the affected device, resulting in a DoS condition.

Una vulnerabilidad en la funcionalidad de visibilidad y control de aplicaciones (AVC-FNF) de Cisco IOS XE Software for Cisco Catalyst 9800 Series Wireless Controllers podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) en un dispositivo afectado. Esta vulnerabilidad es debido a una insuficiente verificación de paquetes para el tráfico inspeccionado por la función AVC. Un atacante podría explotar esta vulnerabilidad mediante el envío de paquetes diseñados desde la red cableada a un cliente inalámbrico, resultando en que los paquetes diseñados fueran procesados por el controlador inalámbrico. Una explotación con éxito podría permitir al atacante causar un bloqueo y recarga del dispositivo afectado, resultando en una condición de DoS
