Phoenix Contact vulnerabilities and threats

A low privileged remote attacker with file access can replace a critical file used by the watchdog to get read, write and execute access to any file on the device after the watchdog has been initialized.

An low privileged remote attacker can enforce the watchdog of the affected devices to reboot the PLC due to incorrect default permissions of a config file.

An unauthenticated adjacent attacker is able to configure a new OCPP backend, due to insecure defaults for the configuration interface.

An unauthenticated remote attacker can alter the device configuration in a way to get remote code execution as root with specific configurations.

An unauthenticated local attacker can inject a command that is subsequently executed as root, leading to a privilege escalation.

An unauthenticated adjacent attacker can modify configuration by sending specific requests to an API-endpoint resulting in read and write access due to missing authentication.

A low privileged local attacker can leverage insecure permissions via SSH on the affected devices to escalate privileges to root.

A local attacker with a local user account can leverage a vulnerable script via SSH to escalate privileges to root due to improper input validation.

A physical attacker with access to the device display via USB-C can send a message to the device which triggers an unsecure copy to a buffer resulting in loss of integrity and a temporary denial-of-service for the stations until they got restarted by the watchdog.

An unauthenticated remote attacker can use MQTT messages to trigger out-of-bounds writes in charging stations complying with German Calibration Law, resulting in a loss of integrity for only EichrechtAgents and potential denial-of-service for these stations.

An unauthenticated remote attacker can use MQTT messages to crash a service on charging stations complying with German Calibration Law, resulting in a temporary denial-of-service for these stations until they got restarted by the watchdog.

An unauthenticated remote attacker may use an uncontrolled resource consumption in the IEC 61131 program of the affected products by creating large amounts of network traffic that needs to be handled by the ILC. This results in a Denial-of-Service of the device.
