Local privilege escalation via malformed IOCTL input
Published Jul 11, 2024 · Updated Aug 27, 2025
Improper input validation in Foxboro.sys in Foxboro DCS Core Control Services 9.8 and earlier allows local users to escalate privileges via IOCTL. The driver accepts attacker-controlled IOCTL data without adequate validation, but Schneider Electric has not disclosed the specific field or check that fails. Local user access is required; the documented outcomes are local denial of service and privilege escalation, while kernel execution is described as potential.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
