Restrict Admin Access
allLimit admin panel access to specific IP addresses or VPN
Add IP restrictions to .htaccess or web server configuration
🧯 If You Can't Patch
- Implement web application firewall rules to detect and block CSRF patterns
- Require re-authentication for sensitive operations like data deletion
🔍 How to Verify
Check if Vulnerable:
Check if /admin/ca_deal.php accepts POST requests without CSRF token validation when accessed with admin sessionCheck Version:
Check CMS version in admin panel or read version filesVerify Fix Applied:
Test that all admin forms include unique CSRF tokens and reject requests without valid tokens📡 Detection & Monitoring
