The vulnerability is due to insufficient authentication of the parent access point in a mesh configuration. An attacker could exploit this vulnerability by forcing the target system to disconnect from the correct parent access point and reconnect to a rogue access point owned by the attacker. An exploit could allow the attacker to control the traffic flowing through the impacted access point or take full control of the target system. This vulnerability affects the following products running a vulnerable version of Wireless LAN Controller software and configured for meshed mode: Cisco 8500 Series Wireless Controller, Cisco 5500 Series Wireless Controller, Cisco 2500 Series Wireless Controller, Cisco Flex 7500 Series Wireless Controller, Cisco Virtual Wireless Controller, Wireless Services Module 2 (WiSM2). Note that additional configuration is needed in addition to upgrading to a fixed release.

La vulnerabilidad se debe a una autenticaci\u00f3n insuficiente del punto de acceso padre en una configuraci\u00f3n de malla. Un atacante podr\u00eda explotar esta vulnerabilidad forzando al sistema de destino a desconectarse del punto de acceso padre correcto y volver a conectarse a un punto de acceso deshonesto propiedad del atacante. Un exploit podr\u00eda permitir al atacante controlar el tr\u00e1fico que fluye a trav\u00e9s del punto de acceso afectado o tomar el control total del sistema de destino. Esta vulnerabilidad afecta a los siguientes productos que ejecutan una versi\u00f3n vulnerable del software Wireless LAN Controller y est\u00e1n configurados para el modo de malla: Controlador inal\u00e1mbrico Cisco 8500 Series, Controlador inal\u00e1mbrico Cisco 5500 Series, Controlador inal\u00e1mbrico Cisco 2500 Series, Controlador inal\u00e1mbrico Cisco Flex 7500 Series, Controlador inal\u00e1mbrico virtual Cisco , Wireless Services Module 2 (WiSM2).
