Successful exploitation of this vulnerability requires the controller to be configured for WebAuth. 4) An error when using CPU based access control lists can be exploited to view and modify the configuration by connecting to the device on TCP port 1023. Please see the vendor's advisory for a list of affected products and versions. SOLUTION: Apply update (please see the vendor's advisory for details).
