Description

This module exploits a command injection vulnerability in the open source
network management software known as LibreNMS. The community parameter used
in a POST request to the addhost functionality is unsanitized. This parameter
is later used as part of a shell command that gets passed to the popen function
in capture.inc.php, which can result in execution of arbitrary code.

This module requires authentication to LibreNMS first.
