QID Detection Logic (Unauthenticated):
This QID checks for vulnerable instance of WSO2 server by sending a crafted request to the webserver.

By leveraging the XSS attack, a malicious actor can make the browser get redirected to a malicious website, make changes in the UI of the web page, retrieve information from the browser or harm otherwise. However, since all the session related sensitive cookies are set with httpOnly flag and protected, session hijacking or similar attacks would not be possible.
