Patch Version: Unknown
Vendor Advisory: https://www.sourcecodester.com/
Restart Required: No
Instructions:
No official patch available. Check vendor website for updates or implement workarounds.
🔧 Temporary Workarounds
Input Validation Enhancement
allAdd server-side validation for the 'total' parameter to ensure it matches calculated order totals.
Edit /foms/routers/place-order.php to add validation logic before processing payments
WAF Rule Implementation
allDeploy web application firewall rules to detect and block manipulation of price calculation parameters.
Add WAF rule to monitor and block suspicious 'total' parameter values
🧯 If You Can't Patch
- Implement additional payment verification step where order totals are recalculated independently before finalizing transactions.
- Monitor payment logs for discrepancies between submitted totals and expected order calculations.
🔍 How to Verify
Check if Vulnerable:
Test by submitting an order with manipulated 'total' parameter values to see if the system accepts incorrect payment amounts.Check Version:
Check the software version in the admin panel or configuration files.Verify Fix Applied:
Verify that manipulated 'total' parameter values are rejected and proper validation errors are returned.📡 Detection & Monitoring
Log Indicators:
- Unusual payment amounts, mismatches between order items and final totals, repeated failed payment validations
Network Indicators:
- HTTP POST requests to /foms/routers/place-order.php with suspicious 'total' parameter values
SIEM Query:
source="/foms/routers/place-order.php" AND (total != expected_calculation OR total contains suspicious_pattern)
