Enbra EWM 1.7.29 does not check for or detect replay attacks sent by wireless M-Bus Security mode 5 devices. Instead timestamps of the sensor are replaced by the time of the readout even if the data is a replay of earlier data.

Weakness

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