CVE-2024-54141
📋 TL;DR
phpMyFAQ versions before 4.0.0 expose database credentials in error messages when database connection fails. This allows attackers to obtain sensitive database credentials, potentially leading to full database compromise. All phpMyFAQ installations using affected versions are vulnerable.
💻 Affected Systems
- phpMyFAQ
📦 What is this software?
Phpmyfaq by Phpmyfaq
⚠️ Risk & Real-World Impact
Worst Case
Attackers obtain database credentials, gain full database access, extract sensitive FAQ data, user information, and potentially pivot to other systems using the same credentials.
Likely Case
Attackers trigger database connection errors through various means, capture exposed credentials, and gain unauthorized database access to read/modify FAQ content and user data.
If Mitigated
Proper error handling prevents credential exposure, limiting impact to service disruption without information disclosure.
🎯 Exploit Status
Exploitation requires inducing database connection failure, which can be achieved through network manipulation or resource exhaustion.

🔍 How to Verify
Check if Vulnerable:
Check phpMyFAQ version in admin panel or by examining source files for version markersCheck Version:
grep -r 'phpMyFAQ Version' /path/to/phpmyfaq/ || cat /path/to/phpmyfaq/inc/Configuration.php | grep 'version'Verify Fix Applied:
After upgrade, attempt to trigger database connection error and verify credentials are not exposed in error messages📡 Detection & Monitoring
Log Indicators:
- Database connection error messages containing credential strings
- Multiple failed database connection attempts from single source
Network Indicators:
- Unusual traffic patterns to database port from web server
- SQL queries from unexpected sources
