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

<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>
