  # Date: 2019-12-17
  # Exploit Author: MTK
  # Vendor Homepage: https://sweethawk.co/zendesk/survey-app
  # Software Link: https://www.zendesk.com/apps/support/survey/
  # Version: Up to v1.6

  # Software description:
  # Sweet Hawk Survey app ask customers for a 0-10 score instead of the normal good or bad question. 
  # You can get more granular satisfaction data without compromising the response rate. 
  # Ask an optional NPS question on the landing page. View reports and drill down into the response 
  # detail and go directly to the ticket. Easy to set up, just replace the survey place holder in 
  # your trigger or automation. Customize the landing pages for each of your brands.
  
  # Technical Details & Impact:
  # Attackers use vulnerable web pages to inject malicious code and have it stored on the web server 
  # for later use. The payload is automatically served to users who browse web pages and executed in 
  # their context. Thus, the victims do not need to click on a malicious link to run the payload. 
  # All they have to do is visit a vulnerable web page.
  
  # POC
  
  1. Open Support ticket in Zendesk and send XSS payload e.g;
  <script>alert(1);</script>
  2. Generate surveyrequest to rate the ticket and payload will execute;
