Every protocol is vulnerable if the principals are mis-configured (i.e. do not
follow the protocol).
The protocol for crossing a busy street at the light involves checking for
the green light before crossing the street. A mis-configured principal checks
the light, ignores red or yellow, and immediately crosses. Does it mean that
the protocol is broken or does it mean that a principal is broken?

P.S. In this specific case I am strictly looking at "misconfiguration causes
problems" implies brokenness of the protocol.
