The administrative web interface on the Cisco Wireless LAN Controller (WLC) platform 4.2 before 4.2.205.0 and 5.x before 5.2.178.0, as used in Cisco 1500 Series, 2000 Series, 2100 Series, 4100 Series, 4200 Series, and 4400 Series Wireless Services Modules (WiSM), WLC Modules for Integrated Services Routers, and Catalyst 3750G Integrated Wireless LAN Controllers, allows remote attackers to cause a denial of service (device reload) via a malformed response to a (1) HTTP or (2) HTTPS authentication request, aka Bug ID CSCsx03715.

Security readout for executives and security teams

This is a Cisco Wireless LAN Controller administrative interface flaw that can make an affected controller reload. If a legacy controller is still running vulnerable 4.2 or 5.x software and its web administration interface is reachable, wireless service availability could be disrupted. Exposure is most likely in organizations still operating legacy Cisco WLC, WiSM, ISR WLC modules, or Catalyst 3750G integrated controllers with reachable administrative web interfaces. Prioritize if legacy Cisco wireless controllers remain in production, especially where Wi-Fi supports business operations. The main risk is service disruption, not confirmed data compromise. Mitigation focus: Upgrade Cisco WLC software to 4.2.205.0, 5.2.178.0, or later supported guidance.; Restrict administrative HTTP and HTTPS access to trusted management networks only.; Disable unnecessary administrative web exposure where operationally possible..
