📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining full control over the server, data exfiltration, lateral movement, and persistent backdoor installation.
Likely Case
Attackers upload webshells to execute arbitrary commands, steal sensitive data, deface websites, or use the system as a foothold for further attacks.
If Mitigated
Limited impact with proper file upload restrictions, but potential for other vulnerabilities if system remains unpatched.
🎯 Exploit Status
Exploitation requires admin access to the vulnerable endpoint. The GitHub reference contains detailed exploitation methodology.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative software or implementing strict file upload controls.
🔧 Temporary Workarounds
Implement File Upload Restrictions
allAdd server-side validation to restrict file uploads to specific extensions and implement file type verification.
Modify /admin/add_room_controller.php to validate file extensions and MIME types
Restrict Admin Access
allImplement IP whitelisting or VPN access for the admin interface to reduce attack surface.
Add .htaccess rules or web server configuration to restrict /admin/ directory access
🧯 If You Can't Patch
- Disable the vulnerable endpoint or remove the entire admin interface if not needed
- Implement Web Application Firewall (WAF) rules to block malicious file uploads
🔍 How to Verify
Check if Vulnerable:
Attempt to upload a file with malicious extension (e.g., .php, .jsp) to /admin/add_room_controller.php endpoint and check if it's accepted without proper validation.Check Version:
Check the software version in the application interface or configuration files.Verify Fix Applied:
Test file upload functionality with various file types to ensure only allowed extensions are accepted and proper validation is in place.📡 Detection & Monitoring
