Descriptions

A vulnerability in the 802.11 frame validation functionality of the Cisco Wireless LAN Controller (WLC) 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 incomplete input validation of certain 802.11 management information element frames that an affected device receives from wireless clients. An attacker could exploit this vulnerability by sending a malformed 802.11 management frame to an affected device. A successful exploit could allow the attacker to cause the affected device to reload unexpectedly, resulting in a DoS condition. This vulnerability affects only Cisco Wireless LAN Controllers that are running Cisco Mobility Express Release 8.5.103.0. Cisco Bug IDs: CSCvg07024.

Una vulnerabilidad en la funcionalidad de validación de tramas 802.11 de Cisco Wireless LAN Controller (WLC) podría permitir que un atacante adyacente no autenticado provoque el reinicio inesperado de un dispositivo afectado, lo que provocaría una condición de denegación de servicio (DoS). La vulnerabilidad se debe a la validación de entrada incompleta de determinadas tramas de elementos de información de gestión 802.11 que recibe un dispositivo afectado de clientes inalámbricos. Un atacante podría explotar esta vulnerabilidad enviando una trama de gestión 802.11 mal formada a un dispositivo afectado. Su explotación exitosa podría permitir al atacante causar que el dispositivo afectado se reinicie inesperadamente, resultando en una condición de denegación de servicio (DoS). Esta vulnerabilidad sólo afecta a los controladores de LAN inalámbrica de Cisco que ejecutan Cisco Mobility Express Release 8.5.103.0. Cisco Bug IDs: CSCvg07024.
