Patch Version: Unknown
Vendor Advisory: https://itsourcecode.com/
Restart Required: No
Instructions:
No official patch is available. Check the vendor website for updates. Consider implementing workarounds or migrating to alternative software.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement proper input validation and parameterized queries for the Password parameter in login_crud.php
Manual code modification required - replace vulnerable SQL queries with prepared statements
Web Application Firewall (WAF) Rules
allDeploy WAF rules to block SQL injection attempts targeting the login endpoint
Add WAF rule: Block requests containing SQL injection patterns to /admin/app/login_crud.php
🧯 If You Can't Patch
- Isolate the billing system behind a firewall with strict access controls
- Implement network segmentation to limit database access from the billing system
🔍 How to Verify
Check if Vulnerable:
Test the /admin/app/login_crud.php endpoint with SQL injection payloads in the Password parameterCheck Version:
Check the software version in the application interface or configuration filesVerify Fix Applied:
Verify that SQL injection attempts no longer succeed and that parameterized queries are implemented📡 Detection & Monitoring
