                                            `PR09-04: Cross-Site Scriting on Portwise SSL VPN v4.6  
Vulnerability found: 25th March 2009  
Vendor informed: 28th April 2009  
Vulnerability fixed:  
Severity: Medium  
The Portwise portal login page is vulnerable to XSS. Portwise is a  
SSL-VPN portal.  
Note: Other version might be affected as well  
The following demonstrate XSS:  
1) Login page XSS;%3Cscript%3Eblah%3C/script%3E%3Cscript%3Ealert(document.cookie)%3C/script%3E  
An attacker may be able to cause execution of malicious scripting code  
in the browser of a user who clicks on a link to a Portwise Portal-based  
site. Such  
code would run within the security context of the target domain. This  
type of attack can result in non-persistent defacement of the target  
site, or the  
redirection of confidential information (i.e.: session IDs) to  
unauthorised third parties.  
Ensure all input parameters (especially "reloadFrame") are filtered  
sufficiently before beign echoed back to the client.
