      "value": "An improper ownership management vulnerability has been identified in Moxa’s Secure Router. Because of improper ownership management, a low-privileged authenticated user may access a configuration file containing the hashed password of the administrative account. Successful exploitation of this vulnerability could allow an attacker to obtain sensitive information. Exploitation is only possible under a specific condition — when the configuration file has been exported. This vulnerability does not impact the integrity or availability of the affected product, and no confidentiality, integrity, or availability impact to the subsequent system has been identified."

      "value": "Una vulnerabilidad de gestión de propiedad inadecuada ha sido identificada en el Secure Router de Moxa. Debido a una gestión de propiedad inadecuada, un usuario autenticado con bajos privilegios puede acceder a un archivo de configuración que contiene la contraseña hash de la cuenta administrativa. La explotación exitosa de esta vulnerabilidad podría permitir a un atacante obtener información sensible. La explotación solo es posible bajo una condición específica - cuando el archivo de configuración ha sido exportado. Esta vulnerabilidad no tiene impacto en la integridad o disponibilidad del producto afectado, y no se ha identificado ningún impacto en la confidencialidad, integridad o disponibilidad en el sistema subsiguiente."
