CVE-2020-16209
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA malicious attacker could exploit the interface of the Fieldcomm Group HART-IP (release 1.0.0.0) by constructing messages with sufficiently large payloads to overflow the internal buffer and crash the device, or obtain control of the device.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceBuffer overflow vulnerability in Fieldcomm Group HART-IP version 1.0.0.0 allows remote attackers to send specially crafted messages with oversized payloads that overflow an internal buffer, potentially enabling denial of service (device crash) or remote code execution (device control takeover).

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.
-
Identify HART-IP components in your environmentInventory all systems running Fieldcomm Group HART-IP software, Hipserver, or Hart Ip Developer Kit. Check installed programs, running services, and device firmware listings.Affected if Any Hipserver version 3.6.1 or Hart Ip Developer Kit Firmware version 1.0.0.0 is found in the environment
-
Verify Hipserver versionLocate the Hipserver installation directory and check the version information (version file, executable properties, or software inventory). Compare to the affected version 3.6.1.Affected if Hipserver version is exactly 3.6.1
-
Verify Hart Ip Developer Kit firmware versionCheck the firmware version on affected devices or consult device management interfaces. Compare to the affected version 1.0.0.0.Affected if Hart Ip Developer Kit firmware version is exactly 1.0.0.0
-
Assess network exposure of HART-IP serviceDetermine if HART-IP services are accessible from network segments. Review firewall rules, exposed ports, and network accessibility of devices running HART-IP.Affected if HART-IP service is network-accessible to untrusted hosts
Environment is affected if either Hipserver version 3.6.1 or Hart Ip Developer Kit Firmware version 1.0.0.0 is present AND the HART-IP service is network-accessible, allowing remote attackers to send oversized payloads.

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 dataApply vendor-supplied patch or firmware update if available; until then, implement network segmentation and firewall rules to restrict HART-IP traffic to authorized hosts only, and deploy intrusion detection to monitor for anomalous payload sizes.
