description: popper_mod is a free, full featured web based POP3 email client written 
in PHP. It is an extension of the now abandoned "popper" project. 
It can be downloaded from http://www.symatec-computer.com/forums/

bug report: popper_mod 1.2.1 relied on administrators using htaccess authentication to 
protect the administration PHP script.  Unfortunately, I have found no administrator 
yet who has protected their admin script access.  

exploit: simply go to http://www.targetdomain.com/mail/admin  
Your identity as administrator is not verified in anyway, and the complete list of 
user accounts including the passwords is revealed.  You can also delete accounts, 
manipulate settings, and modify accounts.

fix: popper_mod 1.2.2 and above require the administrator to log in with a username 
and password.  As of this advisory, latest version is 1.2.3 which can be downloaded 
from http://www.symatec-computer.com/forums/viewtopic.php?t=14
