Reflected cross site scripting (XSS) vulnerability allows authenticated remote attackers to inject arbitrary web script or HTML into HTTP/POST parameter which reflects/store the user input without sanitization.

Step-by-step instructions and PoC

The Web application does not properly check the parameters sent as input from clients before they are re-included within the HTTP pages returned by the application. In particular, the web gui is affected by the reflected type of this vulnerability. Due to the lack of validation of user input, it allows an attacker to modify the HTML code and the expected execution flow could be altered. The attack can be performed post authentication.
