The Emerson ControlWave Next Generation RTUs through 2022-05-02 mishandle firmware integrity. They utilize the BSAP-IP protocol to transmit firmware updates. Firmware updates are supplied as CAB archive files containing a binary firmware image. In all cases, firmware images were found to have no authentication (in the form of firmware signing) and only relied on insecure checksums for regular integrity checks.

Weakness

The product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data.
