MEDIUM 6.5EPSS 0.23%

Does this matter?

Lower severity and a low EPSS score (0.23%). Track it; it rarely justifies an emergency change on its own.

Description

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.
