What is SQL Injection? SQL Injection (SQLi) is a code injection technique that exploits vulnerabilities in an application's software by manipulating SQL queries. It allows attackers to interfere with the queries that an application makes to its database. This can lead to unauthorized access to sensitive data, data manipulation, and even complete control over the database server. Types of SQL Injection: In-band SQL Injection: The simplest and most common form, where the attacker uses the same communication channel to both launch the attack and gather results. Error-based SQLi: Relies on error messages thrown by the database server. Union-based SQLi: Uses the UNION SQL operator to combine results from multiple SELECT statements. Inferential SQL Injection: The attacker does not see the output of the query but can infer information based on the application's response. Boolean-based SQLi: The attacker sends a query that forces the application to ...
