🎯 Testing Methodologies

Error-Based Detection

Basic Syntax Errors: ', ", \
Logic Operators: OR, AND, UNION
Database Functions: VERSION(), DATABASE(), USER()
Information Schema: information_schema.tables

Time-Based Detection

MySQL: SLEEP(5), BENCHMARK()
PostgreSQL: PG_SLEEP(5)
MSSQL: WAITFOR DELAY '00:00:05'
Oracle: Custom delay techniques

Boolean-Based Detection

True Conditions: AND 1=1, AND 'a'='a'
False Conditions: AND 1=2, AND 'a'='b'
Conditional Logic: IF(), CASE WHEN

🛡️ Supported Databases

Database	Error Detection	Time Detection	Boolean Detection	Confidence
MySQL	✅ Excellent	✅ Excellent	✅ Excellent	95%+
PostgreSQL	✅ Excellent	✅ Excellent	✅ Excellent	95%+
Microsoft SQL Server	✅ Very Good	✅ Excellent	✅ Very Good	90%+
Oracle	✅ Good	⚠️ Limited	⚠️ Basic	80%+
SQLite	⚠️ Basic	❌ No	⚠️ Basic	60%+

🚨 CONFIRMED VULNERABLE PAYLOADS:
• 1'
• 1' OR '1'='1
• 1' AND SLEEP(5)--

🔧 Advanced Configuration

Custom Payloads

Modify payload arrays in source files:

// In advanced_sqli.c
const char* custom_payloads[] = {
    "your_custom_payload_here",
    "another_payload' OR 1=1--",
    NULL  // Always end with NULL
};

Timing Configuration

// Adjust timing thresholds
#define SLEEP_DELAY 2          // Base delay for time-based tests
#define CONFIDENCE_THRESHOLD 70 // Minimum confidence for reporting

Response Handling

// Modify buffer sizes
#define MAX_RESPONSE_SIZE 16384  // Maximum response size
#define MAX_URL_SIZE 1024        // Maximum URL length

🐛 Troubleshooting

Compilation Issues

# Missing libcurl development package
sudo apt-get install libcurl4-openssl-dev

# Missing build tools
sudo apt-get install build-essential

# Manual compilation
gcc -o sql_injection sql_injection.c -lcurl -lm

Runtime Issues

Connection refused: Check if target URL is accessible
SSL certificate errors: Tool automatically bypasses SSL verification
Timeout errors: Increase timeout in source code
Permission denied: Ensure executable permissions (chmod +x)

False Positives

Use the verification tool: ./verify_sqli <url>
Check confidence scores (>70% recommended)
Manual verification with multiple payloads
Cross-validate with professional tools like SQLMap
