Descriptions

A vulnerability in the quality of service (QoS) feature of Cisco Aironet Series Access Points (APs) could allow an authenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper input validation on QoS fields within Wi-Fi frames by the affected device. An attacker could exploit this vulnerability by sending malformed Wi-Fi frames to an affected device. A successful exploit could allow the attacker to cause the affected device to crash, resulting in a DoS condition.

Una vulnerabilidad en la característica quality of service (QoS) de Aironet Access Points (APs) de Cisco, podría permitir a un atacante identificado localmente generar una condición de denegación de servicio (DoS) en un dispositivo afectado. La vulnerabilidad se debe a la comprobación de entrada incorrecta en los campos de QoS dentro de las tramas Wi-Fi por el dispositivo afectado. Un atacante podría aprovechar esta vulnerabilidad enviando tramas Wi-Fi malformadas a un dispositivo afectado. Una operación con éxito podría permitir que el atacante hiciera que el dispositivo afectado se bloqueara, resultando en una condición de DoS.
