Descriptions

A vulnerability in Cisco Aironet Series Access Points Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to the improper processing of client packets that are sent to an affected access point (AP). An attacker could exploit this vulnerability by sending a large number of sustained client packets to the affected AP. A successful exploit could allow the attacker to cause the affected AP to crash, resulting in a DoS condition.

Una vulnerabilidad en el Software Cisco Aironet Series Access Points podría permitir a un atacante no autenticado adyacente causar una condición de denegación de servicio (DoS) sobre un dispositivo afectado. La vulnerabilidad es debido al procesamiento inapropiado de los paquetes del cliente que se envían hacia un punto de acceso (AP) afectado. Un atacante podría explotar esta vulnerabilidad mediante el envío de una gran cantidad de paquetes de clientes sostenidos hacia el AP afectado. Una explotación con éxito podría permitir al atacante causar que el AP afectado se bloquee, resultando en una condición DoS.
