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.
