Cisco Finesse Reflected Cross-Site Scripting Vulnerability

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 [“https://sec.cloudapps.cisco.com/security/center/content/CiscoAppliedMitigationBulletin/cisco-amb-20060922-understanding-xss”] and the OWASP reference page Cross-site Scripting (XSS) [“https://www.owasp.org/index.php/Cross-site_Scripting_(XSS)”].
