SQL-InjectionToday I am gonna show you how hackers get into a website using SQL injection with the Havij tool.

Things you will need –>

  1. Havij SQL injection Tool: There is a free version HERE, but your probably want to look around and see if you can get your hands on the full-version.
  2. A SQL vulnerable site, Here is the example site:
    • http://toyonorte.com.co/catalogo_nuevos_detalle.php?id=2
  3. A very important thing you will need: your mind.

Checking for SQL vulnerability —>

Now to check is this site vulnerable to SQL, a hacker will simply add ‘ (apostrophe) after the site url like this:

http://toyonorte.com.co/catalogo_nuevos_detalle.php?id=2′

and the hacker will get this error on the site

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘\” at line 1

It means that site is vulnerable to SQL injection.

Exploiting the vulnerable site —>

  1. Open Havij and paste site url in target field and hit enter.
  2. Now wait for Havij to get all the databases of the website.
  3. Now the hacker clicks on available database of site and click on Get Tables. Here, they select 535480_toyonorte for this site like in this image:
    1
  4. By clicking Get Tables Havij will look after the tables available in the database.
  5. Now after the scanning Havij will get all tables, now the main work will start , they must  check if there table available with a name that has something to do with admin, users and something similar. Here, we have a table called usuario in this website. It is selected and then click on Get Columns.
  6. Now after clicking Get Columns havij will get all the columns available in users table.
  7. In this case, the hacker found different columns like id, login, pass and many more.
  8. Now select the columns and click on Get Data like in pic given below.
  9. Now havij will look after the data available in columns login and password i.e admin username and password like i getusername –> adminpassword–> 21232f297a57a5a743894a0e4a801fc3 (in encrypted form)Such as in the image below
  10. Now after they have found the username and password there is a problem. The password is encrypted in md5 language , so the hacker must crack it .
  11. To crack encrypted password the hacker copies the password click on MD5 tab in havij and paste the encrypted password in MD5 hash field and hit start. Now havij will try to crack the password.
  12. Now they get the Password cracked for admin.
  13. The hacker will check for admin panel where they will login with username and password.
  14. To find admin panel click Find Admin tab in Havij and click start. Now havij will check the admin panel of website.

In this case, they found http://toyonorte.com.co/admin/ as admin panel and open it in a web browser. They login with username and password and now they have control of the website.
