-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 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.
