Does this matter?

Lower severity and a low EPSS score (0.26%). Track it; it rarely justifies an emergency change on its own.

Description

The use of a hard-coded cryptographic key was discovered in firmware version 3.60 of the Click Plus PLC. The vulnerability relies on the fact that the software contains a hard-coded AES key used to protect the initial messages of a new KOPS session.
