A vulnerability in version 0.90 of the Open Floodlight SDN controller software could result in a denial of service attack and crashing of the controller service. This effect is the result of a flaw in OpenFlow protocol processing, where specific malformed and mistimed FEATURES_REPLY messages cause the controller service to not delete switch and port data from its internal tracking structures.

A vulnerability in version 0.90 of the Open Floodlight SDN controller software could allow an attacker with access to the OpenFlow control network to selectively disconnect individual switches from the SDN controller, causing degradation and eventually denial of network access to all devices connected to the targeted switch.

Floodlight version 1.2 and earlier contains a Cross Site Scripting (XSS) vulnerability in the web console that can result in javascript injections into the web page. This attack appears to be exploitable via the victim browsing the web console.
