OVERVIEW

A potential Reflected Cross-Site Scripting (XSS) vulnerability has been identified in the Datasource creation page of the Management Console.

DESCRIPTION

A reflected XSS attack could be performed in the Datasource creation page of the Management Console by sending an HTTP GET request with a harmful request parameter.

IMPACT

An attacker can trick a privileged user to click a crafted URL via email or a neutral website, then the attacker 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.
