SQL Injection Testing Methodology

Overview

SQL Injection allows attackers to interfere with database queries, potentially accessing or modifying data.

Types

1. Union-based: Extract data via UNION SELECT
2. Error-based: Extract data via error messages
3. Blind Boolean: Infer data from true/false responses
4. Blind Time-based: Infer data from response delays
5. Stacked Queries: Execute multiple statements
