Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Consider implementing workarounds or migrating to alternative software.
🔧 Temporary Workarounds
Implement File Upload Restrictions
allAdd server-side validation to restrict file uploads to specific extensions and implement file type verification.
Modify submitproperty.php to include: $allowed_extensions = ['jpg', 'png', 'pdf']; $file_extension = strtolower(pathinfo($_FILES['file']['name'], PATHINFO_EXTENSION)); if(!in_array($file_extension, $allowed_extensions)) { die('Invalid file type'); }
Web Application Firewall Rules
allConfigure WAF to block requests to submitproperty.php with suspicious file extensions.
Add WAF rule: Block requests to /submitproperty.php where file extension not in (jpg, png, pdf, gif)
🧯 If You Can't Patch
- Disable the submitproperty.php endpoint if not required
- Implement network segmentation to isolate the vulnerable system
🔍 How to Verify
Check if Vulnerable:
Attempt to upload a file with a .php extension to the /submitproperty.php endpoint. If successful, system is vulnerable.Check Version:
Check system documentation or configuration files for version informationVerify Fix Applied:
Attempt the same upload test after implementing restrictions. Upload should be rejected for unauthorized file types.📡 Detection & Monitoring
Log Indicators:
- Unusual file uploads to submitproperty.php
- Uploads of non-image file types
- Multiple failed upload attempts
Network Indicators:
- HTTP POST requests to /submitproperty.php with suspicious file extensions
- Unusual outbound connections from the server
SIEM Query:
source="web_server" AND uri="/submitproperty.php" AND (file_extension="php" OR file_extension="exe" OR file_extension="sh")
