[ Overview ]
        The product line formerly known under the name of "Ascend" running 
        the TAOS Operating System provides an easy to use and support 
        interface. This interface includes an undocumented protocol that 
        provides an easy method to identify and query the devices. (similar 
        to the Cisco CDP problem but remote).
        
[ Description ]
        When sending a crafted UDP packet to the devices UDP discard port (9),
        the device will answer with a packet containing valuable information 
        such as the host's name, MAC, IP address of the Ethernet Interface,
        Serial number, device type and installed features. By sending a packet 
        with the SNMP WRITE community, a remote attacker can change the devices 
        IP address, netmask or name.
