Fix Available:  Yes  Vendor Confirmed:  Yes

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

Two scripts not properly filter HTML code from user-supplied input before displaying the input. A remote user can cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the Barracuda Web Filter 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 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 'Existing Authentication Services' listing in 'NTLM Edit - Host & Domain Name' is affected.

The upload key tab in combination with a specially crafted short domain in 'Upload Key Tab File' is affected.

The vendor was notified on May 8, 2012.
