🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available, or implement workarounds.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd parameterized queries or input validation to the update_user.php file
Edit /admin/update_user.php to use prepared statements with parameterized queries
Access Restriction
allRestrict access to the admin directory using web server configuration
Add 'Deny from all' to .htaccess in /admin directory or equivalent web server configuration
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block SQL injection patterns targeting /admin/update_user.php
- Isolate the chat system in a segmented network with strict access controls
🔍 How to Verify
Check if Vulnerable:
Test the /admin/update_user.php endpoint with SQL injection payloads in the 'id' parameterCheck Version:
Check the software version in the application interface or configuration filesVerify Fix Applied:
Verify that SQL injection payloads no longer execute and return appropriate error messages📡 Detection & Monitoring
