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 web site, then the attacker can make the browser to get redirected to a malicious website, make changes in the UI of the web page, retrieve information from the browser or harm otherwise.
