      Websense Blocked Sites XSS
    ------------------------------------------------------------------------

    SUMMARY

    When <http://www.websense.com> Websense blocks a web site, it returns a
    web page to the browser stating that the site has been blocked. This error
    message contains the URL which was requested. Websense does not do any
    validation or encoding of the URL before returning it in the error
    message. This allows an attacker to supply a URL that contains JavaScript,
    ActiveX, VB, etc). This script will run in the context of a server in the
    trusted domain and combined with other IE flaws can have serious
    consequences.

    DETAILS

    Vulnerable systems:
     * Websense Enterprise version 4.3.0 up to version 5.1

    Example:
    A URL like: http://BlockedSite?< SCRIPT>alert('hello')</SCRIPT> can be
    used to demonstrate the issue.

    Resolution:
    The vendor has come out with a patch (The vendor was notified on Nov 29,
    2003).
