Description:
A vulnerability has been reported in Cisco WLAN (Wireless LAN) Controllers, which can be exploited by malicious people to bypass certain security restrictions.
The vulnerability is caused due to the WLAN controller accepting unencrypted traffic from end hosts even when it is configured to perform encryption. This can be exploited to send malicious traffic to a secure wireless network by spoofing the MAC address of a legitimate, already authenticated end host.
Successful exploitation requires that the access points are operating in LWAPP (Lightweight Access Point Protocol) mode, and controlled by a separate WLAN Controller.
The vulnerability has been reported in Cisco 1200, 1131, and 1240 series access points controlled by Cisco 2000 and 4400 series Airespace WLAN Controllers with software version 3.1.59.24.
