<p>
lighttpd is a small-footprint, fast, compliant and very flexible
web-server which is optimized for high-performance environments.

<description>
<p>
lighttpd uses file extensions to determine which elements are programs
that should be executed and which are static pages that should be sent
as-is. By appending %00 to the filename, you can evade the extension
detection mechanism while still accessing the file.

</p>
</impact>
<workaround>
<p>
