CVE Reference:   CVE-2006-3108   (Links to External Site)
Updated:  May 22 2009

Version(s): 6.1
Description:   Soroush Dalili from GrayHatz Security Group (GSG) reported a vulnerability was reported in EmailArchitect Email Server. A remote user can conduct cross-site scripting attacks.

The script filtering function does not properly filter HTML code from user-supplied input before displaying the input. A remote user can send e-mail with specially crafted text. When the e-mail message is viewed by the target user, arbitrary scripting code will be executed by the target user's browser. The code will originate from the site running the EmailArchitect Email Server software and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, 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 filtering can be bypassed with an event tag that has empty lines following the even type. A demonstration exploit tag is provided:

<div onmouseover

="alert('Vuln')">

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the EmailArchitect Email Server software, 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.
Solution:   No solution was available at the time of this entry.
Vendor URL:  www.emailarchitect.net/emailserver/ (Links to External Site)
Cause:   Input validation error
Underlying OS:  Windows (2000), Windows (2003), Windows (XP)

Message History:   None.
