Hi, I'm Soroush Dalili from GrayHatz Security Group (GSG). I found multiple bugs in 
MailEnable Enterprise Edition ASP Version <= 2.0 that I listed them below:

1) - Any user can login to web administration site.
2) - Authenticated normal user can gain ADMIN or SYSADMIN level, also remote user can disable him/her account!
3) - Every one (ever no authenticated user) can write a message in "Draft" folder of any users!
4) - Every one can make "myupload.ams" on server in "drafts" folder of every user!
5) - Every one can make "_myupload.csv" on server in "drafts" folder of every user!
6) - For changing password it need the current password but current password is mention in source of "ListAttachments.asp" file, if XSS attack or Session hijacking happened then attacker can gain the user's current password.



Details' Descriptions:

1)
Any user can login to web administration site with bug in "main.asp" (Enterprise)

</FORM>
-----------------------End----------------------------

2)
Authenticated normal user can gain ADMIN or SYSADMIN level, also remote user can disable him/her account!

Bug in "MailOptions.asp" file: remote authenticated user can change value of hidden field (name="LoginRights") 
from "USER" to "ADMIN" or "SYSADMIN" and change it's level to up! or change value of hidden field 
(name="LoginStatus") to "0" to disable him/her account!
