Descriptions

A vulnerability in Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to cause a device to reload. The vulnerability is due to incorrect handling of certain valid, but not typical, Ethernet frames. An attacker could exploit this vulnerability by sending the Ethernet frames onto the Ethernet segment. A successful exploit could allow the attacker to cause the device to reload, resulting in a denial of service (DoS) condition.

Una vulnerabilidad en Cisco IOS XE Software, podría permitir a un atacante adyacente no autenticado causar la recarga de un dispositivo. La vulnerabilidad es debido al manejo incorrecto de determinadas tramas Ethernet válidas, pero no típicas. Un atacante podría explotar esta vulnerabilidad mediante el envío de las tramas de Ethernet hacia el segmento Ethernet. Una explotación con éxito podría permitir al atacante causar que el dispositivo se recargue, resultando en una condición de denegación de servicio (DoS).
