Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm product installationIdentify whether Shanghai Sunfull Automation BACnet Server HMI1002-ARM is running in your environment. Check installed software lists, device inventory, or scan for BACnet services on the network.Affected if The product HMI1002-ARM is present in your environment
-
Check installed versionDetermine the exact version number of the BACnet Server HMI1002-ARM installation. Compare your version against the affected version 2.0.4.Affected if The installed version is 2.0.4 or falls within the same release line where the vulnerability exists
-
Verify Message Handler exposureDetermine if the Message Handler component is enabled and accessible. Review service configurations or network service listings to identify if this component is listening and accepting connections.Affected if The Message Handler component is enabled and reachable on the network
-
Assess network accessibilityEvaluate whether the device is accessible from untrusted networks. Check firewall rules, network segmentation, and whether the BACnet service ports are exposed to external or unauthorized networks.Affected if The vulnerable component is reachable from networks outside the trusted zone, particularly the internet
-
Monitor for compromise indicatorsReview system logs, network traffic logs, and any available security alerts for signs of exploitation attempts or successful compromise targeting this device.Affected if Logs show exploitation attempts, unexpected processes, or indicators of compromise related to this service
You are affected if Shanghai Sunfull Automation BACnet Server HMI1002-ARM version 2.0.4 is installed with the Message Handler component exposed to accessible networks.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataSince the vendor did not respond and no patch is available, implement compensating controls including network isolation of the HMI device, network segmentation to restrict unauthorized access, and monitoring for signs of exploitation.
