⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining full control over the server, data exfiltration, lateral movement, and persistent backdoor installation.
Likely Case
Data breach, privilege escalation, and installation of cryptocurrency miners or ransomware on vulnerable systems.
If Mitigated
Limited impact with proper network segmentation, strong authentication, and input validation preventing successful exploitation.
🎯 Exploit Status
Exploitation requires authenticated access but is straightforward once authentication is obtained.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Monitor the official Datart repository for updates and apply when released.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and sanitization for SQL script fields to reject Freemarker template syntax.
Freemarker Sandbox Configuration
allConfigure Freemarker with restricted template processing and disable dangerous directives.
🧯 If You Can't Patch
- Restrict network access to Datart instances using firewalls and only allow trusted IP addresses.
- Implement strong authentication mechanisms and monitor for suspicious authentication attempts.
🔍 How to Verify
Check if Vulnerable:
Check Datart version via web interface or configuration files. If version is v1.0.0-rc.3, system is vulnerable.Check Version:
Check application configuration or web interface for version information.Verify Fix Applied:
Verify version has been updated beyond v1.0.0-rc.3 and test SQL script field with template injection payloads.📡 Detection & Monitoring
Log Indicators:
