📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete system takeover, data theft, ransomware deployment, or creation of persistent backdoors.
Likely Case
Webshell upload allowing unauthorized access to the server, file system manipulation, and potential lateral movement within the network.
If Mitigated
File upload attempts are blocked or logged, preventing successful exploitation while maintaining system functionality.
🎯 Exploit Status
Exploit requires admin access; public disclosure increases weaponization likelihood.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative software or implementing workarounds.
🔧 Temporary Workarounds
Restrict File Upload Types
allImplement server-side validation to only allow specific image file types (jpg, png, gif) and verify file signatures.
Web Application Firewall Rules
allDeploy WAF rules to block requests to /admin/add_cars.php with suspicious file uploads or non-image content.
🧯 If You Can't Patch
- Restrict network access to admin interface using firewall rules or VPN.
- Implement strict file upload validation and store uploaded files outside web root with random names.
🔍 How to Verify
Check if Vulnerable:
Check if /admin/add_cars.php exists and accepts file uploads without proper validation. Attempt to upload a non-image file with image extension.
Check Version:
Check application files or documentation for version 1.0 references.
Verify Fix Applied:
Test file upload functionality with various file types; only valid images should be accepted. Verify uploaded files cannot execute as code.
📡 Detection & Monitoring
Log Indicators:
- Multiple failed upload attempts to /admin/add_cars.php
- Successful uploads of non-image files or files with double extensions
- Unusual file creation in upload directories
Network Indicators:
- HTTP POST requests to /admin/add_cars.php with file uploads
- Subsequent requests to uploaded files with executable extensions
SIEM Query:
source="web_logs" AND uri="/admin/add_cars.php" AND method="POST" AND (content_type="multipart/form-data" OR file_upload="true")
