🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: https://www.campcodes.com/
Restart Required: No
Instructions:
No official patch exists. Consider upgrading to a newer version if available, or implement workarounds.
🔧 Temporary Workarounds
Implement File Upload Validation
allAdd server-side validation to restrict uploaded files to specific extensions (e.g., .jpg, .png) and scan for malicious content.
Modify /admin/voters_add.php to include: $allowed_extensions = ['jpg', 'png', 'gif']; $file_extension = strtolower(pathinfo($_FILES['photo']['name'], PATHINFO_EXTENSION)); if (!in_array($file_extension, $allowed_extensions)) { die('Invalid file type'); }
Restrict Admin Access
ApacheLimit access to the /admin directory via IP whitelisting or strong authentication mechanisms.
Add to .htaccess: Order Deny,Allow
Deny from all
Allow from 192.168.1.0/24
🧯 If You Can't Patch
- Disable the voters_add.php functionality if not required.
- Implement a Web Application Firewall (WAF) with file upload protection rules.
🔍 How to Verify
Check if Vulnerable:
Attempt to upload a file with a malicious extension (e.g., .php) via the /admin/voters_add.php endpoint and check if it's accepted.Check Version:
Check the software version in the admin panel or configuration files.Verify Fix Applied:
Test file upload with restricted extensions; malicious files should be rejected with appropriate error messages.📡 Detection & Monitoring
