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 in Roche Accu-Chek Inform II Base Unit / Base Unit Hub before 03.01.04 and CoaguChek / cobas h232 Handheld Base Unit before 03.01.04. Insecure permissions in a service interface may allow authenticated attackers in the adjacent network to execute arbitrary commands on the operating system.

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 · high confidence

Insecure permissions in a service interface on Roche Accu-Chek Inform II Base Unit and CoaguChek/cobas h232 Handheld Base Unit devices before version 03.01.04 allow authenticated attackers on the adjacent network to execute arbitrary operating system commands, potentially compromising patient data or device functionality.

MitigationApply vendor patch (version 03.01.04 or later) and implement network segmentation to restrict adjacent network access to these medical devices.

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 model label on the physical device or access the device's system information menu. Confirm the device is one of: Roche Accu-Chek Inform II Base Unit, CoaguChek/cobas h232 Handheld Base Unit, or Roche Base Unit Hub.
    Affected if The device model matches one of the affected products listed.
  2. Check the installed firmware version
    Access the device's service menu or system settings to view the firmware version. This is typically found under 'System Information', 'Device Info', or the service interface. Compare the version number to 03.01.04.
    Affected if The firmware version is lower than 03.01.04.
  3. Verify network accessibility of service interface
    From a system on the same network segment as the device, attempt to reach the service interface port if known (common service ports vary by device). Use network scanning tools to identify open ports on the device IP address.
    Affected if The device's service interface is accessible from adjacent network segments without network segmentation.
  4. Check for adjacent network exposure
    Review network infrastructure configurations to determine if the device shares a network segment with untrusted systems or is directly accessible from the hospital/clinic LAN rather than a dedicated medical device VLAN.
    Affected if The device is on a shared network segment with unrestricted access rather than isolated on a dedicated VLAN.

The device is affected if it is a Roche Accu-Chek Inform II, CoaguChek/cobas h232, or Base Unit Hub with firmware version below 03.01.04 and the service interface is accessible from an adjacent network.
