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 · unedited
An issue was discovered on HMS Anybus X-Gateway AB7832-F firmware version 3. The HICP protocol allows unauthenticated changes to a device's network configurations.

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 confidence

The HMS Anybus X-Gateway AB7832-F firmware version 3 has a vulnerability in the HICP protocol that allows unauthenticated attackers to modify device network configurations without any credentials or authentication, potentially enabling network disruption, man-in-the-middle attacks, or device takeover.

MitigationApply vendor firmware updates when available and restrict network access to the device by placing it behind a firewall or in an isolated network segment to prevent unauthenticated HICP protocol access.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the device model
    Locate the HMS Anybus X-Gateway device and confirm the model number is AB7832-F. Check the device label, management interface, or network scan for this specific model identifier.
    Affected if The device is not an AB7832-F model gateway, then it is not affected by this specific CVE.
  2. Determine the firmware version
    Access the device web interface, console, or management software and locate the firmware version information. Compare it against version 3 of the AB7832-F device.
    Affected if The firmware is version 3 on an AB7832-F device, then it is within the affected version range.
  3. Verify HICP protocol exposure
    Check the device network settings or protocol configuration to determine if the HICP protocol is enabled and accessible on the network. HICP typically uses port 9999 or may be listed in the protocol/enabled services section of the device management interface.
    Affected if HICP protocol is enabled and reachable over the network, the vulnerability is exploitable.
  4. Assess network accessibility
    Determine if the device HICP service is exposed to untrusted networks. Check if the device is directly accessible from the internet, guest networks, or untrusted segments rather than being isolated behind a firewall.
    Affected if The device HICP service is accessible from untrusted networks without network segmentation, then it is vulnerable to unauthenticated attacks.

You are affected if you have an HMS Anybus X-Gateway AB7832-F running firmware version 3 with HICP protocol enabled and exposed to untrusted network access.
