Description
The vulnerability allows an adjacent attacker to cause DoS condition on the target system.
The weakness exists in the handling of 802.11w Protected Management Frames (PAF) by Cisco Aironet 3800 Series Access Points due to improper validation of received 802.11w PAF disassociation and deauthentication frames. An adjacent attacker can send a spoofed 802.11w PAF frame from a valid, authenticated client on an adjacent network and terminate a single valid user connection to the affected device.
