A Cross-Site Scripting vulnerability in the F5 Networks FirePass SSL VPN controller that allows execution of arbitrary JavaScript code on the computer of a user as if it genuinely originated from the target domain.
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.
