Summary
o A vulnerability in the web-based management interface of the Cisco
Registered Envelope Service could allow an authenticated, remote attacker
to conduct a cross-site scripting (XSS) attack against a user of the
web-based management interface of the affected service.
The vulnerability is due to insufficient validation of user-supplied input
that is processed by the web-based management interface of the affected
service. An attacker could exploit this vulnerability by persuading a user
of the interface to click a malicious link. A successful exploit could
allow the attacker to execute arbitrary script code in the context of the
interface or access sensitive browser-based information.
