🔧 Temporary Workarounds
Implement CSRF Tokens
allAdd CSRF token validation to the vulnerable endpoint /admin/ca_deal.php
Modify PHP code to generate and validate unique tokens per session
Restrict Admin Access
allLimit admin panel access to specific IP addresses or internal networks
Add IP restrictions in .htaccess or web server configuration
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to detect and block CSRF patterns
- Educate administrators about phishing risks and implement strict browser security policies
🔍 How to Verify
Check if Vulnerable:
Check if /admin/ca_deal.php endpoint accepts POST requests without CSRF token validation when accessed by authenticated admin
Check Version:
Check CMS version in admin panel or configuration files
Verify Fix Applied:
Test that the endpoint now requires and validates CSRF tokens for state-changing operations
