OVERVIEW

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

DESCRIPTION

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

IMPACT
