Descriptions

An unauthenticated remote attacker can modify configurations to perform a remote code execution due to a missing authentication for a critical function.

Un atacante remoto no autenticado puede modificar las configuraciones para realizar una ejecución remota de código debido a una falta de autenticación para una función crítica.

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 CharxSystemConfigManager service, which listens on TCP port 5001 by default. The issue results from the lack of proper validation of a user-supplied string before using it to update a configuration. An attacker can leverage this vulnerability to execute code in the context of the service account.
