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
CWE-787: Out-of-Bounds Write vulnerability exists that could cause local denial-of-service, or kernel memory leak when a malicious actor with local user access crafts a script/program using an IOCTL call in the Foxboro.sys driver.

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

An out-of-bounds write vulnerability (CWE-787) exists in the Foxboro.sys kernel driver where a local attacker with user-level access can craft malicious IOCTL calls to trigger the vulnerability, potentially causing kernel memory leaks or local denial-of-service conditions.

MitigationRestrict local user access to systems with this driver, implement IOCTL call filtering/validation, and apply vendor-provided patches when available. Consider disabling the driver if not required.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 Foxboro.sys driver file
    Search for Foxboro.sys in system driver directories: C:\Windows\System32\drivers\ and review installed program directories for Foxboro DCS components
    Affected if The Foxboro.sys driver file exists on the system
  2. Check installed Ecostruxure Foxboro DCS version
    Inspect the installed version of 'Schneider Electric Ecostruxure Foxboro DCS Control Core Services' via Windows Programs and Features, or query the installed packages using registry key HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall or the program's executable version info
    Affected if The installed version is 9.8 or lower, or if version cannot be determined but the product is present
  3. Verify Foxboro.sys driver loaded state
    Run 'sc query foxboro' or check driver loaded status via 'driverquery /v | findstr -i foxboro' in an administrative command prompt
    Affected if The Foxboro.sys driver is in a RUNNING or STARTED state
  4. Confirm local user access scope
    Review system local user/group membership and privileges granted to users who have access to the system hosting this service
    Affected if Multiple untrusted local users exist with user-level access to the system where Foxboro DCS is installed
  5. Audit IOCTL interface exposure
    Use tools like Sysinternals Process Monitor or kernel debugger to observe IOCTL calls (0x9C402000 range typically) sent to the Foxboro.sys driver device object (\\.\FoxboroDevice or similar)
    Affected if IOCTL calls to the driver can be issued by non-privileged user processes without filtering

A system is affected if Foxboro.sys driver is present and the Ecostruxure Foxboro DCS Control Core Services version is 9.8 or lower, with local user access enabled to the driver interface.

Upgrade available Upgrade to a release after 9.8
Interim mitigation

Restrict local user access to systems with this driver, implement IOCTL call filtering/validation, and apply vendor-provided patches when available. Consider disabling the driver if not required.

Recommended fix Moderate confidence

Version greater than 9.8 (latest available release from Schneider Electric)

  1. 1. Identify the current installed version of Ecostruxure Foxboro DCS Control Core Services by checking the system or consulting the system inventory
  2. 2. Download the latest available version of Ecostruxure Foxboro DCS Control Core Services from the Schneider Electric download portal at download.schneider-electric.com
  3. 3. Review the release notes and upgrade documentation for any specific prerequisites or migration considerations
  4. 4. Create a complete backup of the current system configuration and any critical data
  5. 5. Schedule a maintenance window appropriate for a control system update
  6. 6. Follow Schneider Electric's standard upgrade procedure for Foxboro DCS Control Core Services
  7. 7. After upgrade, verify the Foxboro.sys driver version corresponds to the patched release
  8. 8. Test that the system operates normally and the IOCTL functionality works as expected
Caveat Control system upgrades may require testing of process control loops and should be performed according to plant change management procedures; consult Schneider Electric for any specific compatibility requirements
