CVE-2025-13905

Local privilege escalation via replaceable service binaries

Published Jan 29, 2026 · Updated Jan 29, 2026

Incorrect default permissions in Schneider Electric EcoStruxure Process Expert products allow local users to escalate privileges. Installation-directory permissions let a normal local user replace one or more executable service binaries with a reverse-shell payload. The payload gains the service account's privileges only after the affected service restarts, enabling arbitrary command execution in that context.
