CSRF attacks are well-understood and easy to weaponize with basic web skills.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available, or implement CSRF protections manually.
🔧 Temporary Workarounds
Implement CSRF Tokens
allAdd CSRF token validation to the /admin/?/layout/add endpoint
Manual code modification required - add token generation and validation
Restrict Admin Access
allLimit admin panel access to trusted IP addresses only
Configure web server (Apache/Nginx) to restrict /admin/ path to specific IPs
🧯 If You Can't Patch
- Implement strict SameSite cookie policies and require re-authentication for sensitive actions
- Monitor admin activity logs for unauthorized layout additions and implement alerting
🔍 How to Verify
Check if Vulnerable:
Check if running FrogCMS v0.9.5 and examine /admin/?/layout/add endpoint for CSRF token validationCheck Version:
Check FrogCMS version in admin panel or configuration filesVerify Fix Applied:
Test that CSRF tokens are required and validated for layout addition requests📡 Detection & Monitoring
Log Indicators:
- Multiple failed layout addition attempts
- Layout additions from unusual IP addresses or user agents
Network Indicators:
- POST requests to /admin/?/layout/add without referrer headers or CSRF tokens
SIEM Query:
