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