Just wanted to say that I have very much so enjoyed your posts. Very educational and detailed. If it is “Sometimes” like some yes and some no, then it is a problem If it was working and now not, the page fixed If it was working with a code and the other not, then the other code is wrong.

Only proceed hzcker you know SQL Injection basics. If not, read these posts first. If you’ve read the above three tutorials, you know the basic theory of what SQL Injection is, you know how to carry it out using you web browser on a vulnerable website, and you know how to use SQLMap to automate some of the process. Found a potentially vulnerable website http: Found out the number of rows and columns by making some small changes to the URL which eventually changes the query that is executed on the server We then obtained tutoril of tables, their columns, and finally extracted data.

However, it is worth noting that the website was intentionally left vulnerable, and most often the flaws in security aren’t this obvious. In our case, the website was willingly responding to our queries with errors. This may not always be the case. As long as we can see the errors, haker know we’re going in the right direction. Errors tend to give us clues. However, some websites may choose to suppress the error messages. This make SQLi harder. What I didn’t tell you.

I explained in subtle details what each and every step did. However, I did not explain the motive behind each step. I gave a rough idea in the Sql injection basics post. The purpose of the asterisk ‘ was to find out how the server handles bad inputs. If it has some mechanisms for sanitizing or escaping these dangerous characters, then we would not see any error in output. Now this is not intended to be a theoretical post.


This is an external link. Since their content is not licensed under creative commons, I couldn’t simply crop the important part and put it here, so you have to go to their website PS: The posts in the beginning of the tutorial are mandatory, these are optional reads.

You may choose to skip these and come back later and hackerr whenever you’re free. Now we’ll get started.

Finding a suitable website. We now have to find a website which is vulnerable to SQL Injection, but does not show error messages. Basically, a site which can be hacked into but not using classical attacks. The site will not give any obvious responses bsqk our attacks. This is why it is called a blind SQL Injection. It is hard to know whether we’re doing it right or not. Now there’s a problem. Blind SQLi is quite time consuming.

One first tried the classical attacks, and if they fail, then only they proceed to blind SQLi. I can’t find a website which bsqk mind being attacked, and exposed in public. So I’ll have to use the same old testphp. However, we’re going to assume that it’s not, and attack it without using any of the methods we used in the previous SQLi tutorial.

That being said, blind SQLi involves a lot of guessing, and the fact that I can use union based sql injection classical injection that we did already to find out table names, etc. Now we’ll begin- Finding out if tutorixl is vulnerable. Now the process of finding out other details would be identical. We now know that if we type a true statement after andthen the page is displayed, else it’s not. We can simply keep guessing stuff till we are right, in which case the condition is true, and page is displayed.

Now it is very impractical to expect that we’ll be easily able to guess the complete version, the pic will show you why it’s from the manual SQLi tutorial. However, we don’t need to know the exact version. Tutorual out whether it’s MySQL version hackeg or 5 is sufficient.

For that, nacker can extract a substring from the version, which in tutoriql case, is simply the first character of the version. This tutorlal be done using substr version,1,1. We can then equate it with 4 or 5 to find out which version the website is using. I put this screenshot here to explain why we used substring, we didn’t use the fact that we know the version of SQL already in any way.

Even if you have no clue about the version which is what is going to happen in real life scenarioyou can find out the version by looking at the output of the following URLs.

‘ + relatedpoststitle + ‘

You can read more about Substring clause here. As you might have guessed, the version is 5 since it did not return a blank page. I hope you’ve started to see the pattern now. We will now have to guess the table names. The idea hwcker to start with some common ones, and you’ll most probably get a few tables.



Now I’ll demonstrate a few failures and successes and then we’ll proceed. There is another alternate in which we can go character by character. Since the website does not display output, how do we find out the table names?

We will keep repeating until the condition returns true, i. This is just a concept, how do we put it to action? How do we ask the database to return true if we guess the right table name? We will use the select query. If there is a table called X, then output will be one. Now we can use this output to generate a condition.

If X table exists, then output will be 1. If X does not exist, condition will be false.

What if we can’t guess hackr table name? We have 2 more alternatives. First is to use substr, as we did while finding version, to find out the table name character by character. Basically, we will ask the table if first character of table name is a.

If not, we’ll try b, c, d, etc.

After that we’ll proceed to second character. This way, we are guaranteed to find out the table name. Basically, we can’t directly compare characters like number. Characters can’t be compared like that. We can use this fact to ask the table if the first letter of the table name is more than P or less than it. This way, if the table says it’s more, we don’t have to check the alphabets before P, and Vice Versa.

Now, for finding table name, I’ll stick to simple guessing. The remaining 2 concepts will be demonstrated while finding column name and data value respectively. It must be noted that select query returns all the results from a given table, not just the first. bsq

For example, if a table has records, and you ask the table for records where first table is ‘a’, it will return not one, but all the records with first letter ‘a’. This is not what we want. To avoid this, we use limit clause. Here is a short summary, read the complete section on Limit clause gsql.

LIMIT offsetcount.

Now, there are 2 ways to get column name. The first way is to guess the complete column name, as we did for table name. Now while what you did so far wasn’t very swift either, what you’re going to do now is going to be terribly slow.

You have to guess the data as well. Each and everything needs to be guessed. Anonymous April 30, at 2:
