"According to its self-reported version, the Cisco Finesse Software is affected by a cross-site scripting vulnerability.
This could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of
the web-based management interface of an affected device. The vulnerability is due to insufficient validation of
user-supplied input by the web-based management interface of an affected device. An attacker could exploit this
vulnerability by persuading a user of the interface to click a crafted link. A successful exploit could allow the
attacker to execute arbitrary script code in the context of the interface or allow the attacker to access sensitive
browser-based information.
