CVE-2025-60500
📋 TL;DR
QDocs Smart School Management System 7.1 contains a logic flaw that allows authenticated users with roles like 'accountant' or 'admin' to bypass file type restrictions. By abusing the alternate YouTube URL option in the media upload feature, attackers can upload arbitrary PHP files to a web-accessible directory, potentially leading to remote code execution. This affects all deployments running the vulnerable version.

🔧 Temporary Workarounds
Disable media upload feature
allTemporarily disable the media upload functionality in QDocs Smart School Management System
Restrict upload directory permissions
linuxSet web server permissions to prevent execution of uploaded files in the media directory
chmod -R 644 /path/to/media/uploads/
chown -R www-data:www-data /path/to/media/uploads/
🧯 If You Can't Patch
- Implement strict file upload validation on the web server level (e.g., mod_security rules)
- Deploy web application firewall (WAF) with file upload protection rules
🔍 How to Verify
Check if Vulnerable:
Test if authenticated users can upload PHP files via the alternate YouTube URL option in the media upload featureCheck Version:
Check system version in admin panel or configuration filesVerify Fix Applied:
Verify that PHP files cannot be uploaded through any media upload method, including alternate YouTube URL option📡 Detection & Monitoring
