SQL Injection Fundamentals
Understanding SQL injection concepts and attack vectors
What is SQL Injection?
SQL injection is a code injection technique that attacks data-driven applications
How It Works
- • Malicious SQL statements are inserted into an entry field
- • Application database executes the malicious statements
- • Attackers can bypass authentication, access data, modify database
- • Can lead to complete system compromise
Dangers
- • Data theft and exfiltration
- • Database modification or deletion
- • Authentication bypass
- • Privilege escalation
- • Complete system takeover
Impact: One of the most critical web vulnerabilities, ranked #1 in OWASP Top 10
SQL Injection Types
Different categories of SQL injection attacks
Types
In-band SQLi
Attacker receives immediate response
Examples: Union-based SQLi, Error-based SQLi
Characteristics: Fast feedback, Direct results, Easy to detect
Blind SQLi
No direct error messages from database
Examples: Boolean-based SQLi, Time-based SQLi
Characteristics: No errors visible, Requires inference, More stealthy
Out-of-band SQLi
Attacker triggers external network connections
Examples: DNS exfiltration, HTTP requests
Characteristics: Advanced technique, Can bypass WAF, Complex setup
