SQL Injection Lab

🎯Learning Objective: Advanced SQL Injection Techniques

SQL injection is one of the most critical web application vulnerabilities. This enhanced lab demonstrates multiple attack vectors including basic error-based injection, blind boolean-based attacks, and time-based data extraction techniques used in real-world penetration testing.

Attack Types:

  • • Basic SQLi: Error-based injection
  • • Blind SQLi: Boolean-based inference
  • • Time-based: Timing attack vectors
  • • Data extraction techniques

What You'll Learn:

  • • Advanced SQL injection methodologies
  • • Real-world attack scenarios
  • • Impact on data confidentiality
  • • Detection and prevention techniques

Professional Skills:

  • • OWASP Top 10 #3 - Injection vulnerabilities
  • • Penetration testing methodologies
  • • Security code review techniques
  • • Enterprise security assessments

Attack Mode

User Search

Search for users by username. The backend uses unsafe SQL queries.

Example Payloads

Guided Exercise

1

Baseline Test

Try searching for a normal username like 'admin' or 'alice' to see normal behavior.

2

Test OR Injection

Use the 'Basic OR injection' payload to bypass authentication logic.

3

Try UNION Attacks

Use UNION SELECT to attempt extracting additional data.

4

Analyze Query Manipulation

Observe how malicious input changes the SQL query structure.
