🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None known
Restart Required: No

Implement CSRF Tokens
allAdd CSRF token validation to the /admin/readDeal.php endpoint
Modify PHP code to generate and validate unique tokens per session
Restrict Administrative Access
allLimit administrative interface access to trusted networks only
Configure firewall rules or web server access controls
🧯 If You Can't Patch
- Implement network segmentation to isolate administrative interfaces from general user access
- Use browser extensions that block CSRF attempts and educate administrators about phishing risks
🔍 How to Verify
Check if Vulnerable:
Check if idccms version is 1.35 and examine /admin/readDeal.php for CSRF token validationCheck Version:
Check CMS configuration files or admin panel for version informationVerify Fix Applied:
Test that administrative actions require valid CSRF tokens and fail without them📡 Detection & Monitoring
Log Indicators:
- Multiple failed administrative actions from same IP
- Administrative actions without referrer headers
Network Indicators:
- HTTP POST requests to /admin/readDeal.php without CSRF tokens from unexpected sources
