Security Advisory – Oracle Sun GlassFish Enterprise Server Stored XSS Vulnerability

Sense of Security – Security Advisory – SOS-11-009

Details.

GlassFish is an open source application server project led by Sun Microsystems for the Java EE platform. The proprietary version is called Sun GlassFish Enterprise Server. GlassFish supports all Java EE API  specifications, such as JDBC, RMI, e-mail, JMS, web services, XML, etc, and defines how to coordinate them.

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:

‘>”><script>alert(3);</script>

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. An example is shown below:

/com_sun_webui_jsf/help/helpwindow.jsf?&windowTitle=Help+Window’>”>

<script>alert(1);</script>&helpFile=commontask.html

/com_sun_webui_jsf/help/helpwindow.jsf?&windowTitle=Help+Window&

helpFile=commontask.html’>”><script>alert(1);</script>

Solution.

Apply the vendor patch.
