CVE-2021-1254: Cisco Finesse Cross-Site Scripting Vulnerabilities
First published: Sat May 22 2021(Updated: )
Multiple vulnerabilities in the web-based management interface of Cisco Finesse could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface. These vulnerabilities are due to insufficient validation of user-supplied input by the web-based management interface of the affected software. An attacker could exploit these vulnerabilities by injecting malicious code into the web-based management interface and persuading a user to click a malicious link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information. An attacker needs valid administrator credentials to inject the malicious script code.
