SQL Injection Attacks

SQL injection lets an attacker manipulate a database by inserting malicious code through unvalidated input fields, often with devastating results.

How SQL Injection Works

When user input is inserted directly into a database query without proper validation, an attacker can craft input that alters the query's logic, potentially exposing or modifying data they shouldn't have access to.

What Attackers Can Achieve

A successful SQL injection can allow an attacker to read sensitive data, bypass login authentication, modify records, or in severe cases, gain broader control over the underlying database server.

Common Injection Points

Login forms, search boxes, and URL parameters are frequent targets, since these are the points where user-supplied input most often reaches a database query.

Prevention Techniques

Parameterized queries, input validation, and using an ORM with built-in protections are the standard defenses that prevent user input from ever being interpreted as executable code.
