OVERVIEW

A Remote Code Execution vulnerability in the Management Console.

DESCRIPTION

Due to improper output encoding, a Reflected Cross Site Scripting (XSS) attack can be carried out on the carbon console.

IMPACT

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.
