Descriptions

A vulnerability when handling incoming 802.11 Association Requests for Cisco Aironet 1800 Series Access Point (APs) on Qualcomm Atheros (QCA) based hardware platforms could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected system. A successful exploit could prevent new clients from joining the AP. The vulnerability is due to incorrect handling of malformed or invalid 802.11 Association Requests. An attacker could exploit this vulnerability by sending a malformed stream of 802.11 Association Requests to the local interface of the targeted device. A successful exploit could allow the attacker to cause a DoS situation on an affected system, causing new client 802.11 Association Requests to fail. This vulnerability affects the following Cisco products: Aironet 1560 Series Access Points, Aironet 1810 Series OfficeExtend Access Points, Aironet 1810w Series Access Points, Aironet 1815 Series Access Points, Aironet 1830 Series Access Points, Aironet 1850 Series Access Points, Aironet 2800 Series Access Points, Aironet 3800 Series Access Points. Cisco Bug IDs: CSCvg02116.

Una vulnerabilidad al gestionar peticiones entrantes de asociación 802.11 para los Cisco Aironet 1800 Series Access Point (AP) en plataformas de hardware de Qualcomm Atheros (QCA) podría permitir que un atacante adyacente sin autenticar provoque una denegación de servicio (DoS) en un sistema afectado. Su explotación con éxito podría evitar que nuevos clientes se unan al AP. La vulnerabilidad se debe a la gestión incorrecta de peticiones de asociación 802.11 mal formadas o inválidas. Un atacante podría explotar esta vulnerabilidad enviando un flujo mal formado de peticiones de asociación 802.11 a la interfaz local del dispositivo objetivo. Su explotación con éxito podría permitir que el atacante provoque una situación de denegación de servicio (DoS) en un sistema afectado, lo que provocaría que las nuevas peticiones de asociación 802.11 fracasasen. Esta vulnerabilidad afecta a los siguientes productos Cisco: Aironet 1560 Series Access Points, Aironet 1810 Series OfficeExtend Access Points, Aironet 1810w Series Access Points, Aironet 1815 Series Access Points, Aironet 1830 Series Access Points, Aironet 1850 Series Access Points, Aironet 2800 Series Access Points y Aironet 3800 Series Access Points. Cisco Bug IDs: CSCvg02116.
