Detail

A vulnerability in 802.11 association request frame processing for the Cisco Aironet 1560, 2800, and 3800 Series Access Points could allow an unauthenticated, Layer 2 radio frequency (RF) adjacent attacker to cause the Access Point (AP) to reload, resulting in a denial of service (DoS) condition.

The vulnerability is due to insufficient frame validation of the 802.11 association request. An attacker could exploit this vulnerability by sending a malformed 802.11 association request to the targeted device. An exploit could allow the attacker to cause the AP to reload, resulting in a DoS condition while the AP is reloading.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
