PR07-15: Cross-site Scripting (XSS) / HTML injection on F5 FirePass 4100 SSL VPN 'my.logon.php3' server-side script
Date Found: 19th June 2007
Successfully tested on: version 5.5.2
F5 Networks has confirmed the following versions to be vulnerable:
FirePass versions 5.4.1 - 5.5.2
FirePass versions 6.0 - 6.0.1
F5 Networks FirePass 4100 SSL VPN is vulnerable to XSS within the "my.logon.php3" server-side script.
No authentication is required to exploit this vulnerability.
An attacker may be able to cause execution of malicious scripting code in the browser of a user who visits a specially-crafted URL to an F5 Firepass device, or visits a malicious page that makes a request to such URL. 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. admin session IDs) to unauthorised third parties.
