OVERVIEW

Reflected Cross Site Scripting (XSS) in the authentication endpoint.

DESCRIPTION

Due to lack of output encoding, an attacker can inject a malicious script into the authentication endpoint.

IMPACT

By leveraging the XSS attack, a malicious attack can get the browser 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.
