(_<  
  
Date: 2000, 03/01  
Affected Software: iMail Server 5.0  
Platform: Windows NT 4.0 SP 6a  
  
*Problem*  
A malicous user can read and send emails as any other user on  
the system.  
  
*How*  
The issue lies in how iMail handles the creating of new email  
accounts, and how it stores them.  
  
When iMail is default installed all new email accounts are  
stored in the same directory. So, the directory that held the  
email  
account for admin@domain.com would be stored in the same  
directory as user@otherdomain.com.  
  
*Exploit*  
Now if user@otherdoamin.com has mail administration turned on,  
user could create a new account under his domain  
(otherdomain.com)  
for admin, and since it iMail would store it in the same  
directory as the as the admin@doamin.com account, they would  
then become  
one in the same. Thus allowing user@otherdomain.com to read ALL  
incoming emails to admin@domain.com and all other 'admin' users  
on  
the system by sharing the same 'admin' folder. As you can  
imagine, this could pose a serious risk to security.  
  
*Fix*  
When creating a new email account for a domain in iMail  
Administrator, choose a custom path to save all accounts to.  
Example:  
D:\IMAIL\newdomain.com  
  
As long as an administrator is keeping his eye on the ball this  
little problem can be avoided.  
  
*Notes*  
I have not tested this problem on any earlier version of  
iMail... Other versions are probably affected too. If you find  
out they  
are please email me.

today, this  
means you Anna.
