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
A buffer overflow issue was discovered in the HMI3 Control Panel contained within the Swisslog Healthcare Nexus Panel, operated by released versions of software before Nexus Software 7.2.5.7. A buffer overflow allows an attacker to overwrite an internal queue data structure and can lead to remote code execution.

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.

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 installed product
    Locate the Swisslog Healthcare Nexus Panel and its HMI3 Control Panel component in your environment. This is typically a medical device HMI used for panel control in healthcare facilities.
    Affected if The product is Swisslog Healthcare HMI3 Control Panel running as part of Nexus Panel software.
  2. Determine the firmware version
    Access the HMI3 Control Panel interface or system information page to retrieve the installed firmware version. Consult the device documentation for the specific method (often found under System > About or similar).
    Affected if The displayed firmware version is lower than 7.2.5.7.
  3. Confirm the software version via Nexus Panel
    If separate from the HMI, check the Nexus Panel software version through its administrative interface or system settings.
    Affected if The Nexus Panel software version is prior to 7.2.5.7.
  4. Verify the vulnerability scope
    Confirm that the HMI3 Control Panel component is active and running. The vulnerability exists specifically in this component, not in other Nexus Panel modules.
    Affected if The HMI3 Control Panel component is present and the version is < 7.2.5.7.

You are affected if the Swisslog Healthcare HMI3 Control Panel firmware or Nexus Panel software version is below 7.2.5.7.
