SQL Injection

Overview

Practice detecting and exploiting SQLi safely, then fix the code using prepared statements and validation.

Learning Outcomes

• Boolean-based and time-based exploitation
• UNION-based extraction techniques
• Prevent with parameterized queries and stored procedures
• Validate and sanitize inputs where appropriate
• Understand ORM parameterization strengths/limits

Hands-on Labs

From basic injection to blind techniques, then apply remediations and regression tests.

Defenses

Principle of least privilege for DB users, prepared statements everywhere, and safe error handling.
