🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
No official patch available. Consider workarounds or system replacement.
🔧 Temporary Workarounds
File Upload Restriction
allImplement server-side validation to restrict uploaded file types to images only.
# Add to admin_pic.php: validate file extension and MIME type
# Example: if(!in_array($file_ext, ['jpg','png','gif'])) { die('Invalid file'); }
Access Control
allRestrict access to admin_pic.php via web server configuration or authentication.
# Apache: <Location /admin/admin_pic.php> Require valid-user </Location>
# Nginx: location ~ /admin/admin_pic.php { auth_basic 'Restricted'; }
🧯 If You Can't Patch
- Remove or rename admin/admin_pic.php file from the web directory
- Implement WAF rules to block requests containing suspicious file upload patterns
🔍 How to Verify
Check if Vulnerable:
Attempt to upload a non-image file (e.g., test.php) to admin/admin_pic.php and check if it's accepted.Check Version:
Check system documentation or configuration files for version informationVerify Fix Applied:
Test that only image files are accepted and uploaded files cannot be executed as code.📡 Detection & Monitoring
Log Indicators:
- Unusual file uploads to admin_pic.php
- POST requests with non-image file extensions
- Files with executable extensions in upload directories
Network Indicators:
- HTTP POST requests to /admin/admin_pic.php with file uploads
- Subsequent requests to uploaded files with suspicious extensions
SIEM Query:
source="web_logs" AND uri="/admin/admin_pic.php" AND method="POST" AND (file_extension="php" OR file_extension="exe" OR file_extension="sh")
