Descriptions

A local attacker with low privileges can use a command injection vulnerability to gain root
privileges due to improper input validation using the OCPP Remote service.

Un atacante local con privilegios bajos puede utilizar una vulnerabilidad de inyección de comandos para obtener privilegios de root debido a una validación de entrada incorrecta mediante el servicio remoto OCPP.

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Phoenix Contact CHARX SEC-3100 devices. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the handling of the Charger ID parameter to the Get Diagnostics command. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of the service account.
