Farmer's Fridge Kiosk 2.0.0 Information Disclosure

`  
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:
