=begin Raritan PowerIQ suffers from an unauthenticated SQL injection vulnerability within an endpoint used during initial configuration of the licensing for the product. This endpoint is still available after the appliance has been fully configured.

When saving an NTP server, you can inject a newline (%0a) into the request in order to save a malformed 'server' stanza in the ntp.conf. When syncing with NTP, the application passes the first NTP server to the NTP utility via bash. I was not able to make my malformed NTP server available as the first in the list, thus was not able to achieve RCE. There may be a way to do it though that I am unaware of. Attached is a Metasploit module that I began writing when attempting to achieve RCE but was never able to. This module will A) Pull out the current password hash and salt for the 'admin' user and cache them. B) Update the admin creeds to be 'admin:Passw0rd!' C) Set up the malformed NTP server D) Attempt to sync with NTP. Because I was not able to achieve RCE via that vector, this module does not actually pop a shell, so I am sorry about that. Maybe some PostgreSQL UDF fanciness will be the key.

In order to gain remote command execution, multiple vulnerabilities are used. I use a SQL injection to gain administrative access.
