SQL Injection (SQLi)

This section contains labs related to SQL Injection (SQLi) vulnerabilities. These labs cover different types of SQL injection techniques including:

• Error-based SQLi

• Boolean-based blind SQLi

• Time-based blind SQLi

• Union-based SQLi

• Authentication bypass

• Filter/WAF bypass techniques

Each write-up includes:

• Vulnerability identification process

• Payload crafting strategy

• Enumeration steps

• Data extraction methodology

• Prevention and mitigation notes

The goal is to build a strong, practical understanding of SQL injection exploitation aligned with real-world bug bounty scenarios.
