Disclosure of authentication information, Execution of arbitrary code via network, Modification of user information, User access via network

Version(s): 1.8.1.9

Description:
An input validation flaw was reported in the ArGoSoft Mail Server in the web-mail interface. A remote user can conduct cross-site scripting attacks to obtain a target user's e-mail password.
It is reported that the web-mail interface of the ArGoSoft Mail Server does not properly filter HTML tags from within e-mail messages when displaying them.
A remote user can send e-mail containing HTML that, when viewed by a target user, will cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the ArGoSoft web-mail interface and will run in the security context of that site. As a result, the code will be able to access the target user's ArGoSoft cookies (including authentication cookies), access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user. The ArGoSoft cookies reportedly include the target user's e-mail user name and password in the following form:
mail@domain:password
|
Impact:
A remote user can access the target user's authentication cookies that include the target user's e-mail username and password.
|
Solution:
No solution was available at the time of this entry.

ArGoSoft Web-Mail security problem.
A vulnerability affects ArGoSoft Mail Server Pro for WinNT/2000/XP
(Version 1.8.1.9)
I did not test other versions, this is the only I have, but others should be
vulnerable too. The problem is in the Web-Mail interface, it is posible to
execute javascript by sending it inside a mail, ArGoSoft does not filter
that, and you can steal the cookie from the user, the cookie has a problem
too, it saves the username and the password in plain text, you have only to
decode the cookie, and you have something like that:
mail@domain:password
I would desactivate de Web-Mail interface until a patch is released.
