MDaemon is an e-mail server for Microsoft Windows. RelayFax is a fax server also for Microsoft Windows. Both applications have been developed by the same company than WebAdmin, Alt-N Technologies, and is not included by default with MDaemon, nor with RelayFax.
>From Alt-N Website:

(1) Cross Site Scripting (XSS) ==========================
A Cross Site Scripting exists on the useredit_account.wdm file. Example: http://server/WebAdmin/useredit_account.wdm?user=%3Cscript%3Ealert('test')%3C/script%3E
(2) Users can edit all the user accounts ====================================
There is no validation on the useredit_account.wdm script to disable access to other user accounts. Example: http://server/WebAdmin/useredit_account.wdm?user=otheruser@domain
(3) HTML Injection ==============
The file modalfram.wdm allows to load any web page to make it look as if comes from the WebAdmin server. Example: http://server/WebAdmin/modalframe.wdm?file=http://other_server/page.wdm
This vulnerabilities would not enable an attacker to gain any privileges on an affected computer.
An attacker will need to be able to logon to WebAdmin to take advantage of vulnerability number 2, but he will only be able to view or modify the settings that he can modify on his own account (for example, if an user cannot modify his own "Name", he won't be able to modify the name in any other account, but if he can modify his own "Name", he will be able to modify the name in any other account).
