Description

A vulnerability in the web interface of Cisco Enterprise Chat and Email (ECE) could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface. This vulnerability is due to insufficient validation of user-supplied input that is processed by the web interface. An attacker could exploit this vulnerability by sending a crafted HTTP request to the affected system. A successful exploit could allow the attacker to execute arbitrary code in the context of the interface or access sensitive, browser-based information. To successfully exploit this vulnerability, an attacker would need valid agent credentials.
