Sun Secure Global Desktop prior 4.3 multiple remote vulnerabilities

scip AG Vulnerability ID 2555 (09/21/2006)


Sun Secure Global Desktop (SSGD, formerly known as Tarantella[1]) is an 
open-source remote desktop solution with a basic amount of security.

More information is available at the official product demo web site at 
the following URL:


Marc Ruef at scip AG found six undisclosed web-based vulnerabilities in 
Sun Secure Global Desktop prior 4.3. These can be divided into two classes:

1. Cross site scripting

Some scripts that are not protected by any authentication procedure can 
be used to run arbitrary script code within a cross site scripting attack.

2. Revealing of sensitive information

Some scripts that are not protected by any authentication procedure can 
be accessed to reveal sensitive information (e.g. internal hostnames, 
applied software version, details about settings) about the target host.


Classic script injection techniques and unexpected input data within a 
browser session can be used to exploit these vulnerabilities.

A plugin for the open-source exploiting framework "Attack Tool Kit" 
(ATK) will be published in the near future. [2]

We are not going to publish any further technical details or an exploit 
suite due to Sun has not published any patches as far as we know. See 
vendor response and disclosure timeline for further details.


Because non-authenticated parts of the software are affected, this 
vulnerabilities are serious for every secure environment. 
Non-authenticated users might be able to exploit the flaws to gain 
elevated privileges (e.g. extracting sensitive cookie information or 
launch a buffer overflow attack against another web browser).


Detection of web based attacks requires a specialized web proxy and/or 
intrusion detection system. Patterns for such a detection are available 
and easy to implement.


We have informed sun on a very early stage. They said that the problems 
will be addressed with a bugfix for the currently shipping version 4.2 
and will no longer be existing in the upcoming version 4.3. We were told 
that the public release for the patch is at the end of August 2006. Due 
to no public release was made and our last emails were not answered, we 
do not know what kind of official solution is available. This is why we 
are not going to publish any technical details or exploits at the 
moment. De-activate the following scripts to gain a higher level of

- ttaAuthentication.jsp
- ttalicense.cgi
- ttawlogin.cgi
- ttawebtop.cgi

- test-cgi


Sun Microsystems Inc. has been informed a first time at 07/04/2006 via 
email to Because no reply came back we decided to 
send a forwarding at 07/18/2006 to A first 
response came back on the same day. Several email messages were 
exchanged to discuss the vulnerabilities and to co-ordinate the 
disclosure of this advisory. However, the last emails since 09/15/2006 
have not been answered.
