Description
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.
