present in the Filters and Display model features (OnlineBanking > Web Monitoring > Settings > Filters / Display models). The name of a filter or a display model is interpreted as HTML and can thus embed JavaScript code, which is executed when displayed. This is a stored XSS. Another issue is present in the Notification feature (OnlineBanking > Configuration > Notifications and alerts > Alerts *). The name of an alert is interpreted as HTML, and can thus embed JavaScript code, which is executed when displayed. This is a stored XSS. (Also, an issue is present in the File download feature, accessible via /OnlineBanking/cgi/isapi.dll/DOWNLOADFRS. When requesting to show the list of downloadable files, the contents of three form fields are embedded in the JavaScript code without prior sanitization. This is essentially a self-XSS.)
