CVE-2023-2569
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 · uneditedA CWE-787: Out-of-Bounds Write vulnerability exists that could cause local denial-of-service, elevation of privilege, and potentially kernel execution 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 · high confidenceA CWE-787 Out-of-Bounds Write vulnerability exists in the Foxboro.sys driver where a local attacker with user access can craft malicious IOCTL calls to write beyond allocated buffer boundaries. This memory corruption can cause local denial-of-service, privilege escalation to SYSTEM, and potentially arbitrary kernel code execution.

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 checksWork through these to decide whether this CVE applies to you.
-
Locate the Foxboro.sys driver fileSearch system driver directories (C:\Windows\System32\drivers\ and subdirectories) for the presence of Foxboro.sys fileAffected if The Foxboro.sys driver file exists on the system
-
Identify Foxboro DCS servicesUse the Windows Services console (services.msc) or command 'sc query type= service state= all' to enumerate services, looking for names containing 'Foxboro' or 'Ecostruxure'Affected if Any Foxboro DCS-related services are installed and running on the system
-
Verify service executable pathFor identified Foxboro services, run 'sc qc <service_name>' to query the service configuration and confirm the binary path points to Ecostruxure Foxboro DCS Control Core ServicesAffected if The service binary path references Ecostruxure Foxboro DCS components
-
Assess user access to the driverCheck file permissions on Foxboro.sys using 'icacls' or PowerShell Get-Acl cmdlet to determine which user accounts have read, write, or execute permissionsAffected if Non-administrator user accounts have access to interact with the driver
-
Review service startup configurationRun 'sc queryex type= service state= all' and check the service START_TYPE using 'sc qc <service_name>' to determine if the Foxboro service runs automatically at bootAffected if The Foxboro DCS service is configured to start automatically (AUTO_START) and is currently running
If the Foxboro.sys driver is present on the system and the Foxboro DCS service is running, the environment is affected by this vulnerability since all versions contain the out-of-bounds write flaw in the driver.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor security patches for Foxboro.sys when available. Until patched, restrict local user access to systems running this driver and monitor for suspicious IOCTL call patterns.
