📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise via web shell upload leading to remote code execution, data theft, and lateral movement within the network.
Likely Case
Unauthorized file upload leading to web shell deployment, allowing attackers to execute arbitrary commands, modify system files, and potentially escalate privileges.
If Mitigated
File upload attempts are blocked or logged, preventing successful exploitation while maintaining system functionality.
🎯 Exploit Status
Exploit requires admin access to the /admin/general-setting endpoint. Public exploit code is available in GitHub repositories.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available, or implement workarounds.
🔧 Temporary Workarounds
Restrict file upload types
allImplement server-side validation to only allow specific file types (e.g., .png, .jpg, .ico) for favicon/logo uploads
Implement file extension filtering
allBlock uploads of executable file extensions (.php, .asp, .jsp, .exe, etc.)
Web Application Firewall rules
allDeploy WAF rules to block malicious file upload patterns to /admin/general-setting
🧯 If You Can't Patch
- Isolate the system from the internet and restrict access to trusted networks only
- Implement strict access controls to the /admin/general-setting endpoint and monitor for unauthorized access attempts
🔍 How to Verify
Check if Vulnerable:
Attempt to upload a non-image file (e.g., .php, .txt) to /admin/general-setting endpoint and check if it's acceptedCheck Version:
Check application version in admin panel or configuration filesVerify Fix Applied:
Test that only allowed file types (images) can be uploaded and executable files are rejected📡 Detection & Monitoring
Log Indicators:
- Unusual file uploads to /admin/general-setting
- Uploads of non-image file types
- Multiple failed upload attempts
Network Indicators:
- POST requests to /admin/general-setting with file uploads
- Traffic patterns indicating file upload exploitation
SIEM Query:
source="web_logs" AND uri="/admin/general-setting" AND method="POST" AND (file_extension="php" OR file_extension="asp" OR file_extension="jsp")🔗 References
