# 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;
