Descriptions

Multiple vulnerabilities in the Control and Provisioning of Wireless Access Points (CAPWAP) protocol processing of Cisco IOS XE Software for Cisco Catalyst 9800 Series Wireless Controllers could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition of an affected device. These vulnerabilities are due to insufficient validation of CAPWAP packets. An attacker could exploit these vulnerabilities by sending a malformed CAPWAP packet to an affected device. A successful exploit could allow the attacker to cause the affected device to crash and reload, resulting in a DoS condition on the affected device.

Múltiples vulnerabilidades en el procesamiento del protocolo Control y Provisión de Puntos de Acceso Inalámbricos (CAPWAP) del Software IOS XE de Cisco para los Controladores Inalámbricos Cisco Catalyst serie 9800 podrían permitir que un atacante no autenticado y adyacente causara una condición de denegación de servicio (DoS) de un dispositivo afectado. Estas vulnerabilidades se deben a la insuficiente validación de los paquetes CAPWAP. Un atacante podría explotar estas vulnerabilidades enviando un paquete CAPWAP malformado a un dispositivo afectado. Un exploit exitoso podría permitir al atacante hacer que el dispositivo afectado se estrelle y se recargue, resultando en una condición DoS en el dispositivo afectado
