Description:
Some vulnerabilities were reported in the Ability Mail Server. A remote user can conduct cross-site scripting attacks. A remote user can also cause denial of service conditions.
Dr_insane reported that the 'errormsg' parameter is not properly filtered to remove HTML code. A remote user can create a specially crafted URL that, when loaded by a target user, will cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site running the Ability Mail 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.
Some demonstration exploit URLs are provided:
http://127.0.0.1:8000/_error?id=[id]&errormsg=[exploit_code]
http://127.0.0.1:8000/_error?id=[id]&errormsg=<script>alert(document.cookie)</script>
It is also reported that a remote user can establish approximately 150 to 200 connections to the webmail service (port 8000), admin service (port 8880), and SMTP service (port 25) to cause CPU utilization to reach 100% and cause the system to stop providing any services.
