My understanding of the classical meaning of "remote exploit" is that the
machine can be exploited without the attacker needing to have an account
on the box. A local exploit is one that requires that the attacker first
obtain access to the box. For example, you can exploit ls on a Linux box
to elevate your privileges, if you can first get on the box through ssh or
some other method.

I have never seen remote exploit definitions require the limitation of no
user action.

When discussing taxonomy and the usefulness of vulnerability definitions
in real world scenarios, it's much more useful to know that something can
be exploited without the attacker having access to the box. Certainly a
higher priority is placed on resolving those issues than ones where the
attacker first has to obtain access.
