OVERVIEW

A potential Cross-Site Scripting vulnerability has been identified in the template_wsdl-based.jsp page in the Management Console.

DESCRIPTION

A Cross-Site Scripting attack is possible in template_wsdl-based.jsp page in Management Console by sending malicious a POST request.

IMPACT

By leveraging an XSS attack, an 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.
