Descriptions
Multiple vulnerabilities in the Control and Provisioning of Wireless Access Points (CAPWAP) protocol processing of Cisco IOS XE Software for Cisco Catalyst 9000 Family Wireless Controllers could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. These vulnerabilities are due to insufficient validation of CAPWAP packets. An attacker could exploit the 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.
Varias vulnerabilidades en el procesamiento del protocolo Control and Provisioning of Wireless Access Points (CAPWAP) de Cisco IOS XE Software para Cisco Catalyst 9000 Family Wireless Controllers podrían permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) en un dispositivo afectado. Estas vulnerabilidades son debido a que la comprobación de los paquetes CAPWAP es insuficiente. Un atacante podría explotar las vulnerabilidades mediante el envío de un paquete CAPWAP malformado a un dispositivo afectado. Una explotación con éxito podría permitir al atacante causar que el dispositivo afectado se bloquee y se recargue, resultando en una condición de DoS
