  WolfMail Allows Relaying of SPAM


WolfMail.cgi, is a CGI (like Formmail.cgi) that allows users to send email
via a web interface. The configuration for WolfMail.cgi is not internally
hard coded but rather it is passed via parameters provided by the HTML
input statements, this allows any user to send fake emails.


Most of the configuration of the email sending mechanism is done by
providing HTTP POST values, these values are sent via an HTML file that
can be easily modified, so that for example:
<input type="hidden" name="recipient" value="email@example.com">
<input type="hidden" name="subject" value="From your site...">

Can be easily changed to:
<input type="text" name="recipient" value="spam@mail.com">
<input type="text" name="subject" value="Hi you">
<input type="text" name="abemail" value="fake@mail.com" size="17"

Allowing you to define those two values causing the program to send an
email from fake@mail.com to spam@mail.com.
