SQLMap Overview SQLMap is an open source penetration testing tool written in Python that automates SQL injection detection and exploitation. It connects to a target, probes parameters, fingerprints the back-end DBMS, and then enumerates data or attempts deeper impact. The tool is designed to speed up SQLi workflows while still providing the evidence you need for reporting. SQLMap covers the full exploitation chain in one interface. It can enumerate databases, tables, columns, and users, extract data, and even interact with the file system when the DBMS allows it. It also has features for proxying traffic, adjusting risk, and bypassing common defenses. ...

Introduction SQL injection (SQLi) happens when user input changes the final SQL query sent by a web application. The impact ranges from reading sensitive data to modifying records or writing files on the server. This guide merges database basics with practical SQLi techniques and commands so you can connect theory to hands-on exploitation. Database Foundations Modern web applications rely on databases to store content, user data, and configuration. Understanding DBMS structure and query behavior helps you predict how an injection point will behave and which payloads are likely to work. It also helps you distinguish between relational and non-relational systems when fingerprinting the backend. ...
