Does this matter?

Lower severity and a low EPSS score (0.25%). Track it; it rarely justifies an emergency change on its own.

Description

GE UR bootloader binary Version 7.00, 7.01 and 7.02 included unused hardcoded credentials. Additionally, a user with physical access to the UR IED can interrupt the boot sequence by rebooting the UR.
