[Full-disclosure] F5 FirePass Cross-Site Scripting vulnerability

["Sjoerd Resink" <resink@xxxxxxxxxx>]

=======================================
Vulnerability discovered: May 01, 2009
Reported to vendor: May 14, 2009
Fix available: May 28, 2009
=======================================

PRODUCT
-------------
F5 Networks FirePass SSL VPN controller provides secure access to
corporate applications and data using a standard web browser. More
information can be found at:

VULNERABILITY
-------------
Fox-IT discovered a Cross-Site Scripting vulnerability in the F5
Networks FirePass SSL VPN controller. No authentication is required to
exploit this vulnerability.

EXPLOITATION
-------------
This vulnerability can be used to execute arbitrary JavaScript code on
the computer of a user as if it genuinely originated from the target
domain. In order to do this, an attacker would have to lure the user
into visiting a specially prepared URL. Pages can be modified in such a
way that any data entered into password fields will not only be sent to
the F5 FirePass appliance, but also to the attacker. More advanced
exploits of XSS also enable attackers to abuse the user's computer as a
stepping stone for launching further attacks on the user's internal
network.

FIX
-------------
F5 Networks has released Cumulative HotFix-603-3 for FirePass to address
this vulnerability. More information about obtaining and installing this
patch can be found at:
