CVE-2009-2861 is a vulnerability of currently unknown severity. The Over-the-Air Provisioning (OTAP) functionality on Cisco Aironet Lightweight Access Point 1100 and 1200 devices does not properly implement access-point association, which allows remote attackers to spoof a controller and cause a denial of service (service outage) via crafted remote radio management (RRM) packets, aka "SkyJack" or Bug ID CSCtb56664.. EPSS estimates a 1.04% chance of exploitation in the next 30 days.
