Local / Remote D.o.S Attack in IMail IMONITOR Server for WinNT  
Version 5.08  
  
USSR Advisory Code: USSR-2000030  
  
Release Date:  
January 05, 2000  
  
Systems Affected:  
IMail IMONITOR (PORT 8181) Server for WinNT Version 5.08 and maybe  
other versions.  
IMail Server for WinNT Version 6.0 is not public, so I can't test it  
:(, anyway, I think it's vulnerable.  
  
About The Software:  
Mail Server is the choice of Business, Schools, and Service  
Providers. Unlike Microsoft Exchange and Lotus Notes, which are  
costly to deploy and cumbersome to administer, IMail Server is easy  
to install and easy to manage. It has a fixed cost and is scalable to  
thousands of users per server.  
  
THE PROBLEM  
  
UssrLabs found a bug, in the Imail Imonitor Service, Vulneravility is  
in a Cgi-Script (status.cgi), this Script checks if the Server  
Services is  
runing (and it spends too much Cpu in this operation we might add),  
if you execute the status.cgi, lots of times in a short time the  
Imail Imonitor will  
crash with an "Invalid Memory Address", and our friend DrWatson tells  
us  
to close the program :).  
  
Example:  
Open In Internet Explorer: http://ServerIp:8181/status.cgi  
And you will See something like this.  
  
|---------------------------------|  
|Service | Status |  
|SMTP | UP |  
|POP3 | UP |  
|DNS | UP |  
|WEB | UP |  
|TELNET | UP |  
|FTP | UP |  
|03:33:00 | 03:32:00 |  
|________|________|  
refresh  
  
if you Run the Status.cgi lots of times, the server will crash.
