Summary
Cisco Adaptive Security Appliance (ASA) devices configured for WebVPN contain
a DOM-based cross-site scripting vulnerability (XSS) within the Portal Login
page. An unauthenticated, remote attacker who can convince a user to take a
malicious action, could perform a XSS attack on the user.
The vulnerability exists due to mishandling of certain attributes that are
processed within cookies passed as part of a request. A successful exploit may
allow the attacker to execute arbitrary script or HTML code on the user's
browser within the context of the affected site.
