The Cisco Wireless LAN Controller (WLC), Cisco Catalyst 6500 Wireless Services Module (WiSM), and Cisco Catalyst 3750 Integrated Wireless LAN Controller with software 4.x before 4.2.176.0 and 5.2.x before 5.2.157.0 allow remote attackers to cause a denial of service (device reload) via a web authentication (aka WebAuth) session that includes a malformed POST request to login.html.

Security readout for executives and security teams

This vulnerability can make affected Cisco wireless controller platforms reload when handling a malformed WebAuth login request. The business impact is wireless authentication and access disruption, not documented data theft. It matters most for organizations still running legacy Cisco WLC, WiSM, or Catalyst 3750 integrated WLC software from the affected 4.x or 5.2.x ranges. Exposure is likely limited to legacy Cisco wireless controller deployments running the specified vulnerable software trains with WebAuth in use or reachable. Modernized or upgraded environments are less likely exposed, but asset inventories often miss embedded wireless service modules and old controller appliances. Handle as a targeted availability issue for legacy wireless infrastructure. It is not KEV-listed in the provided data, but affected controllers can disrupt site connectivity if still deployed and unpatched. Mitigation focus: Upgrade 4.x deployments to 4.2.176.0 or later.; Upgrade 5.2.x deployments to 5.2.157.0 or later.; Review the Cisco advisory for platform-specific upgrade guidance..
