      Cross Site Scripting Vulnerability Found in TUTOS
    ------------------------------------------------------------------------

    SUMMARY

     <http://www.tutos.org/homepage/about.html> TUTOS is a tool to manage the
    organizational needs of small groups, teams, departments. Two
    vulnerabilities in the product allows attackers to insert malicious HTML
    and JavaScript code into existing web pages, or upload files that contain
    such malicious content to the server.

    DETAILS

    By submitting the following URL:
    http://[target]/tutos/file/file_select.php?msg=<hostile code>

    An attacker can cause the server to return malicious content inside its
    server reply.

    Further, by using the uploading interface, a user can upload hostile code
    to the server, and then point the user to that file (where the hostile
    code will be automatically executed). This is done via the upload
    interface found in http://[target]/tutos/file/file_new.php?link_id=1065
    (example link). After the file is uploaded, the file can be found by
    accessing this URL: http://[target]/tutos/repository/[project
    number]/[filenumber]/FILE

    Solution:
    The vulnerability was solved for all new releases. The TUTOS server will
    now interpret the <hostile code> as NON-HTML (i.e. disregarding any HTML
    or JavaScript code inside it).

    Vendor status:
    2003-06-20 The vendor has reportedly been notified.
    2003-06-23 Response from the vendor with solution.
