    girex reported that data from the "config_cascade" parameter in
    inc/init.php is not properly sanitized before being used.
    </p>
  </description>
  <impact type="high">
    <p>
    A remote attacker could exploit this vulnerability to execute PHP code
    from arbitrary local, or, when the used PHP version supports ftp://
    URLs, also from remote files via FTP. Furthermore, it is possible to
    disclose the contents of local files. NOTE: Successful exploitation
    requires the PHP option "register_globals" to be enabled.
    </p>
  </impact>
  <workaround>
    <p>
    Disable "register_globals" in php.ini.
    </p>
  </workaround>
  <resolution>
    <p>
    All DokuWiki users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=www-apps/dokuwiki-2009-02-14b&quot;</code>
