CWE-79
Summary
A vulnerability in the web-based management interface of Cisco Finesse 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.
There are no workarounds that address this vulnerability.
For additional information about cross-site scripting attacks and the methods
used to exploit these vulnerabilities, see the Cisco Applied Mitigation
Bulletin Understanding Cross-Site Scripting (XSS) Threat Vectors and the
OWASP reference page Cross-site Scripting (XSS).
