Various Vulnerabilities in SparkleBlog

SparkleBlog is an open-source PHP script which allows you to input and =
edit
your weblog entries, without having to go through the hassle of coding =
in
HTML and uploading via FTP every time you want to make an update.=A0 A =
weblog
(aka blog) is simply an online version of a diary, and blogging has =
become
very popular in recent years.=A0 The time and date is automatically =
added to
the end of each of your blog entries, so people know exactly when you =
posted
them.=A0 The script even allows your website's visitors to make comments =
on
each of your blog entries, if they wish.

No password requied for admin pages. So a remote attacker can request =
the
file and admin the blog site.=20

To answer this in particular, the website says:

"5. Via your domain's control panel, you should password-protect the =
admin
folder, so that only you can add and edit posts. As in Step 1, if you =
are a
hostee, you will need to ask your host to do that for you."

Granted, it is poor way to do it, but it does appear that the script was
written for those who (probably) host their stuff on their own (possibly
poorly) admin'ed boxes, or one of a friends', or a free PHP host, etc. =
This
is not industrial-grade stuff here.
