Put simply

Think of it like a VIP entrance at a club that has no bouncer. Anyone can stroll in without a check, potentially wreaking havoc inside. This is exactly what's happening here with full administrative access up for grabs. This vulnerability allows unauthorized access due to an administrative account, "cmuser", being active without a password, enabling attackers to manipulate critical configurations without any barriers.

What to do
