Descriptions
A vulnerability in the Ident protocol handler of Cisco IOS and IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload. The vulnerability exists because the affected software incorrectly handles memory structures, leading to a NULL pointer dereference. An attacker could exploit this vulnerability by opening a TCP connection to specific ports and sending traffic over that connection. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a denial of service (DoS) condition.
Una vulnerabilidad en el manejador del protocolo Ident de los Software Cisco IOS y IOS XE, podría permitir a un atacante remoto no autenticado causar la recarga de un dispositivo afectado. La vulnerabilidad se presenta porque el software afectado maneja incorrectamente las estructuras de la memoria, lo que conlleva a una desreferencia del puntero NULL. Un atacante podría explotar esta vulnerabilidad abriendo una conexión TCP en puertos específicos y mediante el envío de tráfico por medio de ésta conexión. Una explotación con éxito podría permitir al atacante causar que el dispositivo afectado se recargue, resultando en una condición de denegación de servicio (DoS).
