Technical details

The vulnerability exists in the Model.getDomain function within the WEB-INF/tags/hourlyReport.tag Report Handler component, where the domain argument is not properly sanitized before being reflected in output. This leads to a stored or reflected XSS condition that can be triggered remotely without authentication. An attacker can inject arbitrary JavaScript that executes in the victim's browser with the privileges of the logged-in user.
