UBB.threads 6 SQL Injection




ADZ Security Team
===================
Info

Program: UBB.threads
Version: 6
Module: editpost.php
Bug type: SQL Injection
Vendor site: http://www.ubbcentral.com/ubbthreads/ 
===================
Bug discription

at editpost.php we can see this code:
// START
$Cat = get_input("Cat","get");
$Board = get_input("Board","get");
$Number = get_input("Number","get");
$page = get_input("page","get");
$what = get_input("what","get");
$vc = get_input("vc","get");
// ...........
$query = "
	SELECT
B_Posterid,B_Subject,B_Body,B_Approved,B_Kept,B_Status,B_Main,B_Sticky,
B_Posted,B_Icon,B_Poll,B_Convert,B_Topic,B_CalDay,B_CalMonth,B_CalYear,
B_AddSig,B_Board	FROM  {$config['tbprefix']}Posts
	WHERE B_Number = '$Number'
";
//..........
// END
As we see, $Number not checked as int value, so... :)
