🔧 Temporary Workarounds
File Upload Restriction
allImplement server-side validation to restrict uploaded files to specific safe extensions
# Modify /admin/add_cars.php to validate file extensions
# Example: if(!in_array($ext, ['jpg','png','gif'])) { die('Invalid file type'); }
Admin Interface Protection
allRestrict access to /admin/ directory using .htaccess or web server configuration
# Apache .htaccess: AuthType Basic\nAuthName "Admin Area"\nAuthUserFile /path/to/.htpasswd\nRequire valid-user
# Nginx: location /admin/ { auth_basic "Admin Area"; auth_basic_user_file /path/to/.htpasswd; }
🧯 If You Can't Patch
- Remove or disable the /admin/add_cars.php file entirely
- Implement web application firewall (WAF) rules to block file uploads to vulnerable endpoint
🔍 How to Verify
Check if Vulnerable:
Check if /admin/add_cars.php exists and accepts file uploads without proper validationCheck Version:
# Check version in system files or database: grep -r "version" /path/to/car-rental-system/Verify Fix Applied:
Attempt to upload a non-image file (e.g., .php, .exe) and verify it's rejected📡 Detection & Monitoring
