According to its self-reported version, Cisco Secure Web Appliance is affected by cross-site scripting vulnerabilities. The vulnerability is due to insufficient validation of user input. An attacker could exploit this 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.
