User passwords are considered a lower value asset, so while it should
not be possible for unauthorized users or list admins to get them,
they can still be transmitted in the clear (either via the monthly
reminders -- which can be turned off, or by unprotected http login).
To support the monthly reminders, user passwords are kept in the
database in cleartext. Anyone with shell access and permissions to
the Mailman installation can get them.

This must have been a local system vulnerability. Mailman doesn't use
ftp, anonymous or otherwise.

On your system, sure, if that's how he got in. But this isn't an
attack inherent to Mailman, AFAIK.
