CVE-2019-16063
📋 TL;DR
NETSAS Enigma NMS versions 65.0.0 and earlier fail to encrypt sensitive data in web pages, allowing attackers to intercept and read confidential information. This affects all organizations using vulnerable versions of this network management system.
💻 Affected Systems
- NETSAS Enigma NMS
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete exposure of all sensitive data managed by Enigma NMS including credentials, network configurations, and device secrets, leading to full network compromise.
Likely Case
Unauthorized access to sensitive network management data, potentially enabling further attacks on managed devices.
If Mitigated
Limited data exposure if network segmentation and access controls prevent attacker access to the web interface.
🎯 Exploit Status
Exploitation requires network access to intercept unencrypted web traffic. No authentication bypass needed if attacker can access the web interface.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Versions after 65.0.0
Vendor Advisory: Not publicly available
Restart Required: Yes
Instructions:
1. Contact NETSAS for updated version beyond 65.0.0
2. Backup current configuration
3. Install the updated version
4. Restart Enigma NMS services
5. Verify sensitive data is now encrypted in web pages
🔧 Temporary Workarounds
Enable HTTPS with Strong Encryption
allForce all web interface traffic through HTTPS with TLS 1.2+ to encrypt data in transit
Configure web server to redirect HTTP to HTTPS
Disable weak cipher suites
Enable HSTS headers
Network Segmentation
allRestrict access to Enigma NMS web interface to trusted networks only
Configure firewall rules to limit source IPs
Implement VLAN segmentation
Use VPN for remote access
🧯 If You Can't Patch
- Implement network-level encryption (VPN/SSH tunneling) for all access to Enigma NMS
- Deploy web application firewall to monitor and block suspicious data extraction patterns
🔍 How to Verify
Check if Vulnerable:
Access Enigma NMS web interface and inspect network traffic - check if sensitive data appears unencrypted in HTTP responsesCheck Version:
Check version in web interface footer or via system information pageVerify Fix Applied:
Verify that all web interface traffic uses HTTPS and sensitive data is encrypted in network captures📡 Detection & Monitoring
Log Indicators:
- Multiple failed login attempts
- Unusual access patterns to sensitive data pages
- HTTP traffic to sensitive endpoints
Network Indicators:
- Unencrypted HTTP traffic containing sensitive keywords
- Traffic interception attempts on Enigma NMS ports
