⚠️ Risk & Real-World Impact
Worst Case
An attacker could reset critical system configurations or cause service disruption through forced restarts, potentially leading to extended downtime or misconfigured systems.
Likely Case
Attackers with network access could cause temporary service interruptions by restarting products or resetting non-critical configurations.
If Mitigated
With proper network segmentation and access controls, impact is limited to authorized users who might accidentally trigger these actions.
🎯 Exploit Status
Exploitation requires network access to the vulnerable interface but no authentication. The advisory suggests it can be triggered via web requests.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: v6.81 or later

🔧 Temporary Workarounds
Configure X-FRAME-OPTIONS header
allAdd X-FRAME-OPTIONS header to web server configuration to prevent clickjacking-style attacks
For Apache: Header always append X-Frame-Options SAMEORIGIN
For Nginx: add_header X-Frame-Options SAMEORIGIN;
Network segmentation
allRestrict network access to WebSAM DeploymentManager interface to trusted networks only
🧯 If You Can't Patch
- Implement strict network access controls to limit who can reach the WebSAM DeploymentManager interface
- Monitor for configuration reset or restart events and implement alerting for suspicious activity
🔍 How to Verify
Check if Vulnerable:
Check WebSAM DeploymentManager version via web interface or configuration files. If version is between 6.0 and 6.80, system is vulnerable.Check Version:
Check web interface or consult NEC documentation for version checking methodVerify Fix Applied:
Verify version is 6.81 or later. Test that configuration reset and restart functions require proper authentication.📡 Detection & Monitoring
Log Indicators:
- Unexpected configuration reset events
- Unexpected service restarts
- Access from unauthorized IP addresses to administrative endpoints
Network Indicators:
- HTTP requests to configuration/reset or restart endpoints from unexpected sources
- Lack of X-FRAME-OPTIONS headers in responses
