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."}, {"lang": "es", "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.
