Medium Threat

CWE-321 USE OF HARD-CODED CRYPTOGRAPHIC KEY:

When the REST interface is enabled by the user, and an attacker gains access to the source code and the control network, the attacker can bypass REST interface authentication and gain access to MQTT configuration data.

ABB recommends disabling the REST interface when it is not being used to configure the MQTT functionality. By default, when the REST interface is disabled so there is no risk. The RMC-100 is not intended for access over public networks such as the Internet. An attacker would need access to the user's private control network to exploit these vulnerabilities. Proper network segmentation is recommended.
