Summary

A flaw in the 802.11 frame validation feature of Cisco Wireless LAN Controller may permit an unauthenticated attacker located nearby to force a reload of the device. This situation arises from insufficient input validation on specific 802.11 management frames that the device processes from wireless clients. By dispatching a crafted 802.11 management frame, an attacker can exploit this vulnerability to trigger an unexpected reload of the affected device, leading to a denial of service situation. This issue is specific to Cisco Wireless LAN Controllers operating with Mobility Express Release 8.5.103.0.
