Reflected XSS in the web management interface of Cisco Secure Email and Web Manager 14.3 and earlier allows remote attackers to run scripts. The interface reflects insufficiently validated input from a crafted link into a page, causing the victim browser to execute attacker-controlled script. Exploitation requires a user to follow the link; the script runs in the interface's origin and can access sensitive browser-based information.
