allAdd input validation and parameterized queries to the vulnerable PHP file to prevent SQL injection.
Edit /pages/reprint_cash.php to validate and sanitize the 'sid' parameter using prepared statements
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection protection rules to block malicious requests.
🧯 If You Can't Patch
- Restrict network access to the application using firewall rules to only trusted IP addresses.
- Implement database user with minimal privileges and enable database logging for suspicious queries.
🔍 How to Verify
Check if Vulnerable:
Test the /pages/reprint_cash.php endpoint with SQL injection payloads in the 'sid' parameter (e.g., sid=1' OR '1'='1). Monitor for database errors or unexpected responses.Check Version:
Check the application version in the admin panel or configuration files. The system is version 1.0.Verify Fix Applied:
Retest with SQL injection payloads after implementing fixes. Verify no database errors occur and input is properly sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual database queries in application logs
- SQL syntax errors in web server logs
- Multiple requests to /pages/reprint_cash.php with suspicious parameters
Network Indicators:
- HTTP requests containing SQL keywords (SELECT, UNION, etc.) in the 'sid' parameter
- Unusual database connection patterns from the web server
SIEM Query:
source="web_logs" AND uri="/pages/reprint_cash.php" AND (query="*SELECT*" OR query="*UNION*" OR query="*OR '1'='1*")
