Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:

🔧 Temporary Workarounds
Implement CSRF Tokens
allAdd CSRF token validation to /admin/softBak_deal.php endpoint
Modify PHP code to include and validate CSRF tokens in backup operations
Restrict Admin Access
allLimit administrative interface access to trusted IP addresses only
Add IP-based restrictions to /admin/ directory in web server configuration
🧯 If You Can't Patch
- Implement strict SameSite cookie policies for session management
- Require re-authentication for sensitive administrative actions like database backups
🔍 How to Verify
Check if Vulnerable:
Check if /admin/softBak_deal.php endpoint lacks CSRF token validation by reviewing source code or testing with CSRF PoC toolsCheck Version:
Check CMS version in admin panel or configuration filesVerify Fix Applied:
Test backup functionality with and without valid CSRF tokens to ensure proper validation📡 Detection & Monitoring
