    Advisory Name: Liferay Cross Site Scripting flaw
     Release Date: 05/22/2004
      Application: Liferay (www.liferay.com)
           Author: Sandeep Giri
    Vendor Status: Notified ( 4 months ago)

    Overview:
    (Taken from http://www.liferay.com/products/index.jsp)

    Liferay Enterprise Portal was designed to:

    Provide organizations with a single sign-on web interface for email,
    document
    management, message board, and other useful communication tools.
    Multiple
    authentication schemes (LDAP or SQL) are pooled together so users don't
    have
    to remember a different login and password for every section of the
    portal.
    ...

    Details:

    Liferay is prone to cross site scripting flaw. Almost all the fields
    that takes
    input from one user and are displayed on another user's screen can be
    tricked to
    execute java script code.

    Test:
    Add a message with subject <script>history.go(-1)</script>
    Now, no user can see message board.

    Vendor Response:
    Vendor was notified on 14/01/2004. No fix have been released yet.

    Recommendation:

    While saving or displaying the data:
    replace &,<,> etc with &amp;,&lt; and &gt; respectively.

    Regards,
    Sandeep Giri
