*Steps to Reproduce :*  
*Attack Scenario*:  
Step 1. Login into Desktop Central v.9.1.0  
Step 2: Go to Reports.  
Step 3: Click on Add Schedule Report  
Step 4: Insert XSS payload in "To" parameter of "Specify Delivery Format".  
I have used "><img src=x onerror=prompt(document.cookie)> XSS payload  
Step 5: Then click on Save to submit the data and Script will get execute.  
*Impact of attack*: An attack can perform Cross Site Scripting attack and  
steal the cookie of other active sessions.  
  
An attacker would exploit a vulnerability within a website or web  
application that the victim would visit, essentially using the vulnerable  
website as a vehicle to deliver a malicious script to the victim’s browser.  
  
An attacker might be able to put stored XSS into the website.

*Recommendation*: Use an appropriate combination of white listing and  
blacklisting to ensure only valid and expected input is processed by the  
system.  
Furthermore, classes within the output tag libraries should also be  
modified to encode potentially dangerous characters with their HTML escape  
Counter parts.
