Description (partial)

Symptom:
A vulnerability in the web-based management interface of Cisco Adaptive Security Appliance (ASA) 
could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against 
a user of the web-based management interface of an affected device.

The vulnerability is due to insufficient validation of user-supplied input by the web-based management 
interface of an affected device. An attacker could exploit this vulnerability by persuading a user of 
the interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary
script code in the context of the interface or allow the attacker to access sensitive browser-based information.
