Root escalation via insecure SSH permissions

Published Jul 8, 2025 · Updated Jul 8, 2025

Improper privilege management in Phoenix Contact CHARX SEC-3xxx firmware before 1.7.3 allows local users to gain root access via SSH. Phoenix Contact states only that insecure permissions reachable through SSH let a low-privileged account elevate to root; no file, command, or permission boundary is publicly identified. Exploitation requires a local low-privilege account on an affected charging controller and grants full control of the embedded device.
