<p>
DokuWiki is a standards compliant Wiki system written in PHP.
</p>

<description>
<p>
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 ">=www-apps/dokuwiki-2009-02-14b"</code>
