Descriptions

A vulnerability in the implementation of 802.11v Basic Service Set (BSS) Transition Management functionality in Cisco Wireless LAN Controllers could allow an unauthenticated, adjacent attacker to cause an affected device to reload unexpectedly, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient input validation of 802.11v BSS Transition Management Response packets that an affected device receives from wireless clients. An attacker could exploit this vulnerability by sending a malformed 802.11v BSS Transition Management Response packet to an affected device. A successful exploit could allow the attacker to cause the affected device to reload unexpectedly, resulting in a DoS condition. Cisco Bug IDs: CSCvb57803.

Una vulnerabilidad en la implementación de la funcionalidad 802.11v Basic Service Set (BSS) Transition Management en Cisco Wireless LAN Controllers podría permitir que un atacante adyacente sin autenticar provoque que el dispositivo afectado se reinicie de manera inesperada, resultando en una denegación de servicio (DoS). La vulnerabilidad se debe a una validación insuficiente de los valores entrantes de los paquetes 802.11v de BSS Transition Management Response que un dispositivo afectado recibe de los clientes inalámbricos. Un atacante podría explotar esta vulnerabilidad enviando un paquete 802.11v BSS Transition Management Response mal formado a un dispositivo afectado. Si se explota con éxito, podría permitir que el atacante consiga que el dispositivo afectado se reinicie de manera inesperada, provocando una denegación de servicio. Cisco Bug IDs: CSCvb57803.
