Descriptions
A vulnerability in the Cisco IOx Application Framework of Cisco 809 Industrial Integrated Services Routers (Industrial ISRs), Cisco 829 Industrial ISRs, Cisco CGR 1000 Compute Module, and Cisco IC3000 Industrial Compute Gateway could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient error handling during packet processing. An attacker could exploit this vulnerability by sending a high and sustained rate of crafted TCP traffic to the IOx web server on an affected device. A successful exploit could allow the attacker to cause the IOx web server to stop processing requests, resulting in a DoS condition.
Una vulnerabilidad en el Cisco IOx Application Framework de los Enrutadores Cisco 809 Industrial Integrated Services (Industrial ISRs), Cisco 829 Industrial ISRs, Cisco CGR 1000 Compute Module, y Cisco IC3000 Industrial Compute Gateway, podría permitir a un atacante remoto no autenticado causar una denegación de servicio. (DoS) en un dispositivo afectado. Esta vulnerabilidad es debido a un manejo insuficiente de errores durante el procesamiento de paquetes. Un atacante podría explotar esta vulnerabilidad mediante el envío de una tasa alta y sostenida de tráfico TCP diseñado al servidor web IOx en un dispositivo afectado. Una explotación con éxito podría permitir que el atacante cause que el servidor web IOx dejara de procesar peticiones, lo que resultaría en una condición de DoS
