DokuWiki is a simple to use wiki aimed at creating documentation.

<description>
|
|
<p>
|
|
DokuWiki does not sanitize user input to the GET variable 'media' in
|
|
the fetch.php file.
|
|
</p>
|
|
</description>
|
|
<impact type="low">
|
|
<p>
|
|
An attacker could entice a user to click a specially crafted link and
|
|
inject CRLF characters into the variable. This would allow the creation
|
|
of new lines or fields in the returned HTTP Response header, which
|
|
would permit the attacker to execute arbitrary scripts in the context
|
|
of the user's browser.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
Replace the following line in lib/exe/fetch.php:
|
|
</p>
|
|
<code>$MEDIA = getID('media',false); // no cleaning - maybe external</code>
|
|
<p>
|
|
with
|
|
</p>
|
|
<code>$MEDIA = preg_replace('/[\x00-\x1F]+/s','',getID('media',false));</code>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All DokuWiki users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=www-apps/dokuwiki-20061106"</code>
|
|
</resolution>
