HIGH 8.5

DescriptionCVE.org

A privilege escalation vulnerability in the init-script for user-applications allows a low-privileged local user to execute arbitrary commands as root, resulting in full system compromise.

AnalysisAI

Local privilege escalation in Phoenix Contact CHARX SEC EV charging controllers (SEC-3000/3050/3100/3150, versions 1.0.0 up to 1.9.1) allows a low-privileged local user to execute arbitrary commands as root through a vulnerable init-script for user-applications, yielding full system compromise. Reported by CERT@VDE and classified as OS command injection (CWE-78), the flaw carries a CVSS 4.0 base score of 8.5 (local vector, low privileges required). A vendor patch (1.9.1) is available; no public exploit identified at time of analysis.

Technical ContextAI

The affected devices are the CHARX SEC series of AC EV charging controllers from Phoenix Contact, embedded Linux-based control units used to manage electric-vehicle charge points. The root cause is CWE-78 (Improper Neutralization of Special Elements used in an OS Command), located in the init-script that launches user-applications: the script incorporates attacker-influenceable input into a command executed with root privileges without proper sanitization. Because init/startup scripts on such embedded controllers run as root during service launch, injected commands inherit root, converting a low-privilege foothold into complete control of the device firmware and its charging-control functions.

RemediationAI

Vendor-released patch: upgrade affected CHARX SEC-3000/3050/3100/3150 devices to firmware version 1.9.1 or later, which is the first fixed release per the version range (1.0.0 <1.9.1); follow the guidance in Phoenix Contact/CERT@VDE advisory VDE-2026-008 (https://www.certvde.com/en/advisories/VDE-2026-008/). Until patching is possible, restrict who can obtain any local or low-privileged account on the controller: limit and audit shell/service access, disable or lock unused local accounts, and place the chargers on an isolated management network segment so a remote attacker cannot easily gain the local foothold this bug requires - the trade-off is reduced remote administration convenience but no impact on charging operation. Because exploitation depends on local access, tightening access control and network segmentation directly reduces exposure while the firmware update is staged.
