What is SQL Injection?

SQL injection is a code injection technique, used to attack data driven applications, in which malicious SQL statements are inserted into an entry field for execution (e.g. to dump the database contents to the attacker).[1] SQL injection must exploit a security vulnerability in an application’s software, for example, when user input is either incorrectly filtered for string literal escape characters embedded in SQL statements or user input is not strongly typed and unexpectedly executed. SQL injection is mostly known as an attack vector for websites but can be used to attack any type of SQL databases. In this guide I will show you how to SQLMAP SQL Injection on Kali Linux to hack a website (more specifically Database) and extract usernames and passwords on Kali Linux.

What is SQLMAP

sqlmap is an open source penetration testing tool that automates the process of detecting and exploiting SQL injection flaws and taking over of database servers. It comes with a powerful detection engine, many niche features for the ultimate penetration tester and a broad range of switches lasting from database fingerprinting, over data fetching from the database, to accessing the underlying file system and executing commands on the operating system via out-of-band connections.

Features

1. Full support for MySQL, Oracle, PostgreSQL, Microsoft SQL Server, Microsoft Access, IBM DB2, SQLite, Firebird, Sybase and SAP MaxDB database management systems.
2. Full support for six SQL injection techniques: boolean-based blind, time-based blind, error-based, UNION query, stacked queries and out-of-band.
3. Support to directly connect to the database without passing via a SQL injection, by providing DBMS credentials, IP address, port and database name.
4. Support to enumerate users, password hashes, privileges, roles, databases, tables and columns.
5. Automatic recognition of password hash formats and support for cracking them using a dictionary-based attack.
6. Support to dump database tables entirely, a range of entries or specific columns as per user’s choice. The user can also choose to dump only a range of characters from each column’s entry.
7. Support to search for specific database names, specific tables across all databases or specific columns across all databases’ tables. This is useful, for instance, to identify tables containing custom application credentials where relevant columns’ names contain string like name and pass.
8. Support to download and upload any file from the database server underlying file system when the database software is MySQL, PostgreSQL or Microsoft SQL Server.
9. Support to execute arbitrary commands and retrieve their standard output on the database server underlying operating system when the database software is MySQL, PostgreSQL or Microsoft SQL Server.
10. Support to establish an out-of-band stateful TCP connection between the attacker machine and the database server underlying operating system. This channel can be an interactive command prompt, a Meterpreter session or a graphical user interface (VNC) session as per user’s choice.
11. Support for database process’ user privilege escalation via Metasploit’s Meterpreter getsystem command.

Be considerate to the user who spends time and effort to put up a website and possibly depends on it to make his days end. Your actions might impact someone is a way you never wished for. I think I can’t make it anymore clearer.
