Description

This module exploits a vulnerability found in Project Pier. The application's
uploading tool does not require any authentication, which allows a malicious user
to upload an arbitrary file onto the web server, and then cause remote code
execution by simply requesting it. This module is known to work against Apache
servers due to the way it handles an extension name, but the vulnerability may
not be exploitable on others.
