Descriptions

SAUTER Controls Nova 200–220 Series with firmware version 3.3-006 and prior and BACnetstac version 4.2.1 and prior allows the execution of commands without credentials. As Telnet and file transfer protocol (FTP) are the only protocols available for device management, an unauthorized user could access the system and modify the device configuration, which could result in the unauthorized user executing unrestricted malicious commands.

SAUTER Controls Nova Serie 200–220 con versión de firmware 3.3-006 y anteriores y BACnetstac versión 4.2.1 y anteriores permite la ejecución de comandos sin credenciales. Como Telnet y el protocolo de transferencia de archivos (FTP) son los únicos protocolos disponibles para la administración de dispositivos, un usuario no autorizado podría acceder al sistema y modificar la configuración del dispositivo, lo que podría provocar que el usuario no autorizado ejecute comandos maliciosos sin restricciones.
