Wedding Management System by Wedding Management System Project
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise through remote code execution, data theft, and complete control over the web server.
Likely Case
Webshell deployment leading to data exfiltration, defacement, or lateral movement within the network.
If Mitigated
File uploads blocked or properly validated, limiting impact to denial of service or failed upload attempts.
🎯 Exploit Status
Exploitation requires authentication but is straightforward once authenticated. Public proof-of-concept demonstrates file upload leading to RCE.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. 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 verify MIME types.
Modify users_profile.php to include: $allowed_extensions = ['jpg', 'png', 'gif']; $file_extension = strtolower(pathinfo($_FILES['picture']['name'], PATHINFO_EXTENSION)); if (!in_array($file_extension, $allowed_extensions)) { die('Invalid file type'); }
Restrict Upload Directory Permissions
linuxSet upload directory permissions to prevent execution of uploaded files.
chmod 644 /path/to/upload/directory/*
chmod 755 /path/to/upload/directory/
🧯 If You Can't Patch
- Disable the picture upload functionality in users_profile.php entirely.
- 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 picture upload feature in users_profile.php. If successful, the system is vulnerable.Check Version:
Check the system version in the admin panel or via the source code comments.Verify Fix Applied:
Test the same file upload with a malicious extension; it should be rejected with an error message.📡 Detection & Monitoring
Log Indicators:
- Unusual file uploads with non-image extensions in web server logs
- Access to uploaded .php or .exe files in upload directory
Network Indicators:
- HTTP POST requests to users_profile.php with file uploads containing suspicious content types
SIEM Query:
source="web_logs" AND uri="/users_profile.php" AND method="POST" AND (file_extension="php" OR file_extension="exe")
