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. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
