Descriptions

A low privileged remote attacker can use a command injection vulnerability in the API which performs
remote code execution as the user-app user due to improper input validation. The confidentiality is partly affected.

Un atacante remoto con pocos privilegios puede utilizar una vulnerabilidad de inyección de comandos en la API que realiza la ejecución remota de código como usuario de la aplicación debido a una validación de entrada incorrecta. La confidencialidad se ve parcialmente afectada.

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Phoenix Contact CHARX SEC-3100 devices. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed.
The specific flaw exists within the handling of the filename parameter to the update2-install endpoint. 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 user-app account.
