Description

This module exploits a vulnerability found in Narcissus image configuration
function. This is due to the backend.php file not handling the $release parameter
properly, and then passes it on to the configure_image() function. In this
function, the $release parameter can be used to inject system commands for
passthru (a PHP function that's meant to be used to run a bash script by the
vulnerable application), which allows remote code execution under the context
of the web server.
