Local privilege escalation via Foxboro.sys IOCTL write
Published Jun 14, 2023 · Updated Jan 2, 2025
An out-of-bounds write in EcoStruxure Foxboro DCS Control Core Services before HF9857795 allows local users to gain privileges via Foxboro.sys IOCTL calls. The Foxboro.sys driver mishandles attacker-crafted IOCTL input and writes outside an allocated buffer, enabling denial of service and potentially kernel execution. Exploitation requires local user access on a Windows control workstation or server; successful exploitation can elevate privileges or interrupt service.
