"A vulnerability in the web-based management interface of Cisco AsyncOS Software for Cisco Secure Web Appliance could 
allow an authenticated, remote attacker to conduct an XSS attack against a user of the interface. This vulnerability 
is due to insufficient validation of user input. An attacker could exploit this vulnerability by persuading a user of 
an affected interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary 
script code in the context of the affected interface or access sensitive, browser-based information.

Please see the included Cisco BIDs and Cisco Security Advisory for more information.
