The vulnerability is due to insufficient rate-limiting protection. An attacker could exploit this vulnerability by sending a high rate of TCP packets to a specific group of open listening ports on a targeted device. An exploit could allow the attacker to cause the system to consume additional memory. If enough available memory is consumed, the system will restart, creating a temporary denial of service (DoS) condition. The DoS condition will end after the device has finished the restart process. This vulnerability affects the following Cisco products: Connected Grid Network Management System, if running a software release prior to IoT-FND Release 4.0; IoT Field Network Director, if running a software release prior to IoT-FND Release 4.0. Cisco Bug IDs: CSCvc77164."}, {"lang": "es", "value": "Una vulnerabilidad en el proceso de limitaci\u00f3n TCP para Cisco IoT Field Network Director (IoT-FND) podr\u00eda permitir que un atacante remoto sin autenticar provoque que el sistema consuma memoria adicional, forzando finalmente el reinicio del dispositivo. Esto tambi\u00e9n se conoce como agotamiento de memoria. Esta vulnerabilidad se debe a una protecci\u00f3n de l\u00edmite de tasa insuficiente. Un atacante podr\u00eda explotar esta vulnerabilidad enviando una gran tasa de paquetes TCP a un grupo en concreto de puertos abiertos en escucha en un dispositivo objetivo. La vulnerabilidad podr\u00eda permitir que el atacante provocase que el sistema consuma memoria adicional. Si se consume la suficiente memoria, el sistema se reiniciar\u00e1, creando una condici\u00f3n temporal de denegaci\u00f3n de servicio.
