Patch Version: Unknown - vendor did not respond to disclosure
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Consider upgrading to any version after 2025.08.27 if vendor releases fix, or implement workarounds.
🔧 Temporary Workarounds
Implement strict file upload validation
allAdd server-side validation to restrict file types, check file signatures, and limit file sizes.
Store uploaded files outside web root
allConfigure application to store uploaded files in non-web-accessible directories and serve via secure handlers.
🧯 If You Can't Patch

🔍 How to Verify
Check if Vulnerable:
Attempt to upload a file with malicious extension (e.g., .php, .jsp) to the profile picture upload endpoint and check if it executes.Check Version:
Check Selleo Mentingo version in application interface or configuration files.Verify Fix Applied:
Test that file uploads are properly validated and malicious files are rejected or stored securely.📡 Detection & Monitoring
Log Indicators:
- Unusual file uploads to profile endpoints
- Files with executable extensions in upload directories
- HTTP 200 responses to uploads of non-image files
Network Indicators:
- POST requests to profile picture upload endpoints with unusual file types
- Traffic patterns indicating file upload exploitation
SIEM Query:
source="web_server" AND (uri_path="/upload/profile" OR uri_path="/profile/avatar") AND (file_extension="php" OR file_extension="jsp" OR file_extension="asp")
