Modern day SQL injection obstacles and countermeasures
- Configuration & environment challenges
- IDS, IPS, and web application firewalls
- Common web application firewall HTTPD modules
- Improper sanitizing
- Partial sanitizing
- Deprecated sanitizing
Basic remote tests for SQL injection vulnerabilities
- Injection points
- Input testing
- Your first where clause injection
- Reconstructing injected queries
Bypassing modern SQL injection security measures
- Basic signature evasion
- Whitespace placement
- Integer and string size delimiters
- Switching up the data types
- Arithmetic tests
- Capitalization
- Extending conditional statements
Defeating partial sanitizing
5.2.1 Quotes

Bypassing XSS filters during SQL injection
5.3.1 Testing with BETWEEN
5.3.2 Testing with Regular Expression Operators (REGEXP, ~, and RLIKE)
6 Intermediate SQL injection
6.1 Automation theory
6.2 Basic Injection : Union Select
