🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: https://itsourcecode.com/

Restart Required: No

Instructions:

No official patch available. Consider migrating to alternative voting system or implementing workarounds.

🔧 Temporary Workarounds

Web Application Firewall Rule

all

Block file uploads to /index.php?page=manage_voting endpoint

WAF specific - configure rule to block POST requests with file uploads to vulnerable path

File Upload Restriction

linux

Implement server-side file type validation and restrict upload directory permissions

chmod 755 upload_directory/
Configure PHP to only allow specific file extensions

🧯 If You Can't Patch

  • Isolate the voting system on separate network segment with strict firewall rules
  • Implement application-level input validation and file type checking

🔍 How to Verify

Check if Vulnerable:

Attempt to upload a test file (e.g., test.txt) to /index.php?page=manage_voting and check if it's accepted without proper validation

Check Version:

Check system documentation or admin panel for version information

Verify Fix Applied:

Test file upload with various extensions; only allowed file types should be accepted

📡 Detection & Monitoring

Log Indicators:

  • Multiple file upload attempts to manage_voting endpoint
  • Uploads of suspicious file types (.php, .exe, .sh)

Network Indicators:

  • POST requests with file uploads to vulnerable endpoint
  • Unusual outbound connections from web server

SIEM Query:

source="web_server" AND uri="/index.php?page=manage_voting" AND method="POST" AND content_type="multipart/form-data"
