      Cross Site Scripting in OneCenter Forum
    ------------------------------------------------------------------------

    SUMMARY

     <http://forum.onecenter.com/> OneCenter offers a free discussion forum
    hosted in the company's servers (forum.onecenter.com). Any user in the
    forum is identified by a cookie that contains nick, name, mail address,
    and password. A cross-site scripting vulnerability allows remote attackers
    to grab users' sensitive information.

    DETAILS

    Vulnerable systems:
     * OneCenter forum version 4.0

    This information can be easily obtained as you can add in your posts the
    img html tag with a custom script as follows:
    <img src=javascript:alert(document.cookie);>

    To impersonate any user in the forum (OneCenter administrators would be a
    good choice) you just have to build a cookie like the one obtained and
    visit the forum.
