Security readout for executives and security teams
Cisco Wireless LAN Controllers running older WLC Software can be forced to reload by a nearby unauthenticated attacker. The business impact is wireless service interruption, not data theft. The attacker must be adjacent, so urgency is highest for sites where untrusted devices can reach the controller’s wireless control-plane traffic. Exposure is limited to Cisco Wireless LAN Controller deployments running WLC Software before 8.2.170.0, 8.5.150.0, or 8.8.100.0. Internet exposure is not indicated; adjacency to the affected device is required. Treat as a high-priority availability risk for Cisco-managed wireless sites. It is less severe than a remote code execution flaw, but a successful attack can disrupt business connectivity by reloading controllers. Mitigation focus: Inventory Cisco WLC Software versions across wireless controller fleets.; Upgrade affected WLCs to the applicable fixed release or later per Cisco guidance.; Prioritize controllers supporting critical facilities, guest networks, or high-density sites..
