  <background>
    <p>
    DokuWiki is a wiki targeted at developer teams, workgroups and small
    companies. It does not use a database backend.
    </p>

  <description>
    <p>
    "rgod" discovered that DokuWiki doesn't sanitize the X-FORWARDED-FOR
    HTTP header, allowing the injection of arbitrary contents - such as PHP
    commands - into a file. Additionally, the accessory scripts installed
    in the "bin" DokuWiki directory are vulnerable to directory traversal
    attacks, allowing to copy and execute the previously injected code.
    </p>
  </description>
  <impact type="high">
    <p>
    A remote attacker may execute arbitrary PHP (and thus probably system)
    commands with the permissions of the user running the process serving
    DokuWiki pages.
    </p>
  </impact>
  <workaround>
    <p>
    Disable remote access to the "bin" subdirectory of the DokuWiki
    installation. Remove the directory if you don't use the scripts in
    there.
    </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-20060309d&quot;</code>
  </resolution>
