## INTRODUCTION:
##
##  I recently bought this router for my local
##  network (without modem integrated), now I can tell
##  that it was a bad choice. When my ISP disconnects
##  me from internet, in the most case I have to reboot
##  my Modem and the Router in order to reconnect.
##  So I coded a program (which send http packets) to reboot
##  my router, it asks me the router password, and reboots it.
##  One day I wrote a bad password, but it worked. So I
##  decided to make some tests in order to see if there was
##  a vulnerability.
##
##
## DESCRIPTION:
##
##  Apparently when the router starts, it creates a file
##  (without content) named user.conf, then when we go to
##  SaveCfgFile.cgi, the configuration is saved to the file
##  user.conf. But the problem is that we can access to the
##  file SaveCfgFile.cgi without login.
##
##
## PROOF OF CONCEPT:
## 
##  For example we can get the configuration file here:
##  http://<ROUTER_IP>/SaveCfgFile.cgi
## 
##  pppoe_username=...
##  pppoe_password=...
##  wl0_pskkey=...
##  wl0_key1=...
##  mradius_password=...
##  mradius_secret=...
##  httpd_password=...
##  http_passwd=...
##  pppoe_passwd=...
##
##
##  Tested on the latest firmware for this product
##  (version 3.01.53). 
##
##
## PATCH:
##  
##  Actually (08-01-19) there is no firmware update, but I
##  contacted the author, if they'll release a patch, it
##  will be available here:
