I strongly disagree!
Every piece of software available on the system may the intruder. The
server may not be running so it can not be attacked in the first place.
But if an intruder gains (unprivileged) access to the system, he might
be able to start that server software. Then he might use it for
privilege escalation (if the server software is vulnerable), as a
back-channel or for attacking further systems.

Well, simply by an exploiting a bug in that software. This is a quite
common case :-)
