Stored: The log viewer fails to securely output encode logged values. As a result, an unauthenticated attacker can trigger the application to log a malicious string by entering the values into the username field. This will cause the application to log the incorrect login attempt and results in a stored XSS vulnerability. When an administrator logs into the application and views the log, the malicious code will be executed in the client browser. As an example, navigate to: http://[host]:4848 Enter the below into the login field: '>\"> When the user views the \"Search Log Files\" page, the above client-side code will be executed in the client browser. The offending script is http://[host]:4848/logViewer/logViewer.jsf Reflected: By modifying the windowTitle or helpFile variables of /com_sun_webui_jsf/help/helpwindow.jsf it is possible to trigger a reflected XSS vulnerability.
