Worst Case
Complete database compromise leading to data theft, privilege escalation, and potential remote code execution on the underlying server.
Likely Case
Database information disclosure, data manipulation, and potential administrative access to the Froxlor control panel.
If Mitigated
Limited impact with proper input validation and database user privilege restrictions in place.
🎯 Exploit Status
Exploitation requires access to database configuration functionality, typically requiring some level of authentication.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 0.10.30 and later
Vendor Advisory: https://github.com/Froxlor/Froxlor/commit/eb592340b022298f62a0a3e8450dbfbe29585782
Restart Required: No
Instructions:

🔧 Temporary Workarounds
Input Validation Enhancement
linuxImplement strict input validation for database name parameters
# Modify Database/Manager/DbManagerMySQL.php to sanitize database name inputs
# Add parameterized queries or proper escaping for database name variables
🧯 If You Can't Patch
- Restrict database user privileges to minimum required permissions
- Implement network segmentation to isolate Froxlor from critical systems
🔍 How to Verify
Check if Vulnerable:
Check if Froxlor version is 0.10.29.1 or earlier by examining the version file or admin panel.Check Version:
grep -r 'FROXLOR_VERSION' /path/to/froxlor/install/ || cat /path/to/froxlor/install/lib/version.phpVerify Fix Applied:
Verify installation is running Froxlor 0.10.30 or later and check that Database/Manager/DbManagerMySQL.php contains the security fix from the commit.📡 Detection & Monitoring
Log Indicators:
- Unusual database queries in MySQL logs
- Multiple failed login attempts to Froxlor admin panel
- Unexpected database schema changes
Network Indicators:
- Unusual SQL query patterns to database server
- Multiple requests to database configuration endpoints
SIEM Query:
source="mysql.log" AND ("CREATE DATABASE" OR "DROP DATABASE" OR "INFORMATION_SCHEMA") AND NOT user="expected_user"🔗 References
