Title =========:: Nopam+ Authentication Bypass Vulnerability

Author ========:: Roamer

IRC ===========:: irc.chroot.org #chroot

ScriptName ====:: Green-Computing Nopam+ Spam Filter

ScriptVendor ==:: http://www.green-computing.com/ooweb/index/index.php

[Authentication Vulnerability]

The school I attended had installed Nopam+ to filter spam.
Now I receive the nopam+ report everyday.
But I found something suspicious.

So I surveyed the link as below:
http://nopam.xxx.edu.tw/cgi-bin/mailgw/openwebmail.pl?folder=spam-mail&action=listmessages&logindomain=(mail.xxx.edu.tw)&loginname=(xxxxxxxx)&password=(xxxxxxx)

I found that I can modify the loginname and use the same password(not my e-mail password) to login all spam-mail box.
Even I can modify the logindomain to transfer to another servers' accounts.
If I am an attacker, I can fileter and find some useful messages in all the spam-mail box.
