Security readout for executives and security teams
This CVE can let a remote, unauthenticated attacker crash certain Cisco Wireless LAN Controllers by sending malformed IPv4 fragments. A successful attack causes the controller to reload, creating a denial-of-service condition that may disrupt wireless availability. Exposure is limited to affected Cisco 3500, 5500, and 8500 Series Wireless LAN Controllers running affected 8.4 releases, or 8.5.103.0 and 8.5.105.0 as described by Cisco. Treat as a service-availability risk for wireless infrastructure. Prioritize remediation where affected controllers support business-critical sites, guest access, clinical, retail, warehouse, or operational wireless networks. Mitigation focus: Inventory Cisco 3500, 5500, and 8500 Series Wireless LAN Controllers.; Compare controller software versions against the Cisco advisory.; Upgrade affected controllers to Cisco’s documented first fixed release..
