Name of the Vulnerable Software and Affected Versions Omron FINS protocol (affected versions not specified)

Description The issue concerns the Omron FINS protocol's authenticated feature, which is intended to prevent access to memory regions. However, this authentication is susceptible to brute force attacks.
