The issue is related to insufficient validation of user-supplied input by the web-based management interface of Cisco Security Manager, allowing an unauthenticated, remote attacker to conduct cross-site scripting attacks. An attacker could exploit this by persuading a user to click a crafted link, potentially executing arbitrary script code in the context of the interface or accessing sensitive, browser-based information. The vulnerability is also associated with inadequate protection of the web page structure, which could be exploited using a specially crafted web page.
