[ 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.
