It is possible to inject Javascript into the application which will be  
reflected to unaware application users. This might allow an attacker  
to perform actions on behalf of unaware application users.  
In order to remediate the issue, proper input validation, sanitizing  
and output encoding should be conducted on server side.  
  
No CSRF token is necessary for exploitation.
