Descriptions

A vulnerability with IPv6 UDP ingress packet processing in Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, remote attacker to cause an unexpected reload of the device. The vulnerability is due to incomplete IPv6 UDP header validation. An attacker could exploit this vulnerability by sending a crafted IPv6 UDP packet to a specific port on the targeted device. An exploit could allow the attacker to impact the availability of the device as it could unexpectedly reload. This vulnerability affects Cisco Wireless LAN Controller (WLC) running software version 8.2.121.0 or 8.3.102.0. Cisco Bug IDs: CSCva98592.

Una vulnerabilidad con procesamiento de paquetes de entrada IPv6 UDP en el software Cisco Wireless LAN Controller (WLC) podría permitir a un atacante remoto no autenticado provocar una recarga inesperada del dispositivo. La vulnerabilidad se debe a la validación incompleta del encabezado IPv6 UDP. Un atacante podría explotar esta vulnerabilidad enviando un paquete IPv6 UDP manipulado a un puerto específico del dispositivo de destino.Un exploit podría permitir al atacante afectar la disponibilidad del dispositivo, ya que podría volver a cargarse de forma inesperada. Esta vulnerabilidad afecta a Cisco Wireless LAN Controller (WLC) running software versión 8.2.121.0 o 8.3.102.0. Cisco Bug IDs: CSCva98592.
