"value": "A vulnerability in the Flexible NetFlow Version 9 packet processor 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. The vulnerability is due to improper validation of parameters in a Flexible NetFlow Version 9 record. An attacker could exploit this vulnerability by sending a malformed Flexible NetFlow Version 9 packet to the Control and Provisioning of Wireless Access Points (CAPWAP) data port of an affected device. An exploit could allow the attacker to trigger an infinite loop, resulting in a process crash that would cause a reload of the device."

"value": "Una vulnerabilidad en el procesador de paquetes Flexible NetFlow Versi\u00f3n 9 de Cisco IOS XE Software para los controladores inal\u00e1mbricos Cisco Catalyst serie 9800, podr\u00eda permitir a un atacante remoto no autenticado causar una condici\u00f3n de denegaci\u00f3n de servicio (DoS) sobre un dispositivo afectado. La vulnerabilidad es debido a una comprobaci\u00f3n inapropiada de los par\u00e1metros en un registro de Flexible NetFlow Version 9. Un atacante podr\u00eda explotar esta vulnerabilidad mediante el env\u00edo de un paquete de Flexible NetFlow Version 9 malformado hacia el puerto Control and Provisioning of Wireless Access Points (CAPWAP) de un dispositivo afectado. Una explotaci\u00f3n podr\u00eda permitir al atacante activar un bucle infinito, resultando en un bloqueo del proceso que causar\u00eda una recarga del dispositivo."
