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

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

Heap-based buffer overflow in w32rtr.exe in GE Fanuc CIMPLICITY HMI SCADA system allows remote attackers to execute arbitrary code via unknown vectors. The vulnerability affects versions 7.0 before SIM 9 and versions before 6.1 SP6 Hot fix.

MitigationUpgrade GE Fanuc CIMPLICITY HMI to version 7.0 SIM 9 or later, or to version 6.1 SP6 with Hot fix 010708_162517_6106 or later. Network isolate SCADA systems and restrict external access to w32rtr.exe services.

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. Locate w32rtr.exe on the system
    Search for w32rtr.exe in the GE Fanuc CIMPLICITY installation directory, typically under C:\Program Files\GE Fanuc\CIMPLICITY\ or a custom install path. Use file explorer or command: dir /s C:\w32rtr.exe
    Affected if w32rtr.exe file exists on the system, indicating the vulnerable component is present
  2. Identify the CIMPLICITY version
    Open the GE Fanuc CIMPLICITY program group in the Start Menu and locate the About CIMPLICITY dialog, or check the version info of the CIMPLICITY executable. The version typically appears as 6.1 SP6 or 7.0 SIM8 or similar.
    Affected if The installed version is 6.1 with SP6 Hot fix earlier than 010708_162517_6106, or version 7.0 earlier than SIM9
  3. Verify the w32rtr.exe process is running
    Open Task Manager or use command: tasklist | findstr w32rtr.exe
    Affected if The w32rtr.exe process is actively running, exposing the vulnerable component on the network
  4. Check the exact build date of w32rtr.exe
    Right-click w32rtr.exe, select Properties, then view the Details tab for Product Version and File Version. Compare against the vulnerable build date 010708_162517_6106
    Affected if The file version is older than or equal to the vulnerable build identifier

A system is affected if GE Fanuc CIMPLICITY is installed with w32rtr.exe present and the version is either 6.1 SP6 with Hot fix 010708_162517_6106 or earlier, or 7.0 SIM8 or earlier.

Upgrade available Upgrade to a release after 7.0_sim8
Interim mitigation

Upgrade GE Fanuc CIMPLICITY HMI to version 7.0 SIM 9 or later, or to version 6.1 SP6 with Hot fix 010708_162517_6106 or later. Network isolate SCADA systems and restrict external access to w32rtr.exe services.

Recommended fix High confidence

GE Fanuc CIMPLICITY 7.0 SIM 9 or later; or CIMPLICITY 6.1 SP6 with hotfix 010708_162517_6106 applied

  1. Identify the currently installed GE Fanuc CIMPLICITY version by checking w32rtr.exe properties or the CIMPLICITY About dialog
  2. For CIMPLICITY version 7.0: Upgrade to version 7.0 SIM 9 or later to remediate the vulnerability
  3. For CIMPLICITY version 6.1: Apply hotfix 010708_162517_6106 (6.1 SP6 Hot fix) to remediate the vulnerability
  4. After upgrading or applying the hotfix, verify the w32rtr.exe version matches the fixed release
  5. Test the updated system in a non-production environment before deploying to production
  6. Schedule maintenance window for the update as the w32rtr.exe is the router service
Caveat Review release notes for SIM 9 to check for any configuration or feature changes that may affect existing projects
