    The author made it fairly clear that this exploit applied to non-anonymous
    accounts, which are more trusted by default than the anonymous FTP
    account.  The exploit should also fail for anonymous users in the next
    step which requires rights to do a SITE CHMOD.
    
    The moral of the exploit seems to be that you shouldn't trust people with
    non-anon FTP access who you wouldn't trust with shell accounts.
