What is SQLMap?


What is SQLMap? A penetration testing tool called sqlmap is an open source tool for detecting and exploiting SQL injection flaws, or taking over databases by automated means. The tool contains all the features a penetration tester will need, including a powerful detection engine, a lot of niche features, and a wide range of switches from database fingerprinting to data extraction from databases ,to accessing the underlying file system and executing commands on the operating system via out-of-band connections.

SQLmap automates the process of detecting and exploiting SQL injection. SQL Injection attacks can take control of databases that utilize SQL. They can affect any website or web app that may have a SQL database linked to it, such as MySQL, SQL Server, Oracle and many others.

What is SQLMAP ?

A SQL injection attack attempts to gain access to a web application's database by executing malicious SQL queries. By executing the right set of queries, the attacker is able to control a web application's database. so, this is exactly what is SQLMap.

SQLMAP tests whether a ‘GET’ parameter is vulnerable to SQL Injection. We will cover the basics of SQLmap in this course. SQLmap is an open-source tool used in penetration testing to detect and exploit SQL injection vulnerabilities.It comes with a powerful detection engine, many niche features for the ultimate penetration tester, and a broad range of switches including database fingerprinting, over data fetching from the database, accessing the underlying file system, and executing commands on the operating system via out-of-band connections.

What is SQLMap it's a Python-based tool that detects and exploits SQL injection vulnerabilities in web applications. It should be able to run on any system supporting Python.When it detects one or more SQL injections on the target host, the user can choose from a number of options, including performing an extensive back-end database management system fingerprint, retrieving DBMS session user and database, enumerating users, password hashes, privileges, databases, dumping entire or user-specific DBMS table/columns, running his own SQL statement, reading particular files on the file system and more.

Features of Sqlmap

The following are the features of sqlmap:

1. The database management systems supported by the software include MySQL, Oracle, PostgreSQL, Firebird, Sybase, Microsoft Access, IBM DB2, Microsoft SQL Server, and SAP MaxDB.

2. Stack queries, UNION query, two-stage blind, and error-based SQL injection techniques are all fully supported.

3. A dictionary-based cracking program can automatically recognize password hash formats.

4. Database process user privileges can be escalated using Metasploit's Meterpreter getsystem option

5. Connecting directly to the database without using SQL injection is possible with DBMS credentials, IP address, port, and database name.

6. Allows the attacker to establish an out-of-band stateful TCP connection with the operating system's database server.This channel can take the form of a Meterpreter session, an interactive command prompt session, or a graphical user interface (VNC) session depending on the user's preference.

7. We can upload and download any file from the database server's underlying file system when using mySQL, PostgreSQL, or Microsoft SQL Server.

8. The operating system's built-in database server allows for the execution of arbitrary commands while displaying their standard output when the database software is MYSQL, PostgreSQL, or Microsoft SQL Server.

9. It is possible to search across all databases for a specific database name, specific table, or specific column.

10. The user can choose to dump whole database tables, ranges of entries, or only certain columns of a table depending on their preference. They can also select only specific characters from each column's entry to dump.

11. Users, password hashes, roles, hashes, databases, tables and columns can be enumerated.

Prevent SQL Injection

We can prevent SQL injection by using prepared statements. A prepared statement essentially acts like a template for the code and analyzes both the code and the user input separately. We are able to execute malicious code due to the fact that the input entered by the user is directly inserted into the code and then compiled together. The example given at the beginning of this article illustrates this.Prepared statements are sent as sql queries with placeholders for the user input, and then the actual input is sent as a separate command.

Consider the following php code segment.

$db = new PDO('connection details');

$stmt = db->prepare("Select name from users where id = :id");

$stmt->execute(array(':id', $data));

In this code, the user input is not combined with the prepared statement. They are compiled separately. So even if malicious code is entered as user input, the program will simply treat the malicious part of the code as a string and not a command.

So, this is everything about what is SQLMap? if you like this article then must share it with needy one.
