🧯 If You Can't Patch

  • Block external access to /bank/transfer.php endpoint using firewall rules or web server configuration
  • Implement database monitoring and alerting for unusual SQL queries or data extraction patterns

🔍 How to Verify

Check if Vulnerable:

Test the /bank/transfer.php endpoint with SQL injection payloads in the email parameter (e.g., email=test' OR '1'='1)

Check Version:

# Check PHP application version in admin panel or source code files

Verify Fix Applied:

Verify that SQL injection payloads no longer execute and return appropriate error messages or validation failures

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL queries in database logs
  • Multiple failed login attempts with SQL patterns
  • Access to /bank/transfer.php with suspicious parameters

Network Indicators:
