Description:   A vulnerability was reported in Barracuda Spam Firewall. A remote user can conduct cross-site scripting attacks.

The web administration console does not properly filter HTML code from user-supplied input in the 'username' parameter before displaying the input when the 'Monitor Web Syslog' page is displayed. A remote user can cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the Barracuda Spam Firewall device and will run in the security context of that device. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the device, access data recently submitted by the target user via web form to the device, or take actions on the device acting as the target user.

A demonstration exploit value is provided:

john@<script>alert("String")</script>.blah.com

The vendor was notified on August 24, 2007.
