Descriptions

A vulnerability in the UDP protocol implementation for Cisco IoT Field Network Director (IoT-FND) could allow an unauthenticated, remote attacker to exhaust system resources, resulting in a denial of service (DoS) condition. The vulnerability is due to improper resource management for UDP ingress packets. An attacker could exploit this vulnerability by sending a high rate of UDP packets to an affected system within a short period of time. A successful exploit could allow the attacker to exhaust available system resources, resulting in a DoS condition.

Una vulnerabilidad en la implementación del protocolo UDP para Cisco IoT Field Network Director (IoT-FND) podría permitir que un atacante remoto no autenticado agote los recursos del sistema, lo que resulta en una condición de denegación de servicio (DoS). La vulnerabilidad se debe a la gestión incorrecta de recursos para los paquetes de entrada UDP. Un atacante podría explotar esta vulnerabilidad enviando una gran tasa de paquetes UDP a un sistema afectado en poco tiempo. Si se explota con éxito, podría permitir que el atacante agote los recursos del sistema disponibles, provocando una denegación de servicio (DoS).
