CVE-2022-20639: Cisco Security Manager Cross-Site Scripting Vulnerabilities

First published: Fri Jan 14 2022(Updated: )

Multiple vulnerabilities in the web-based management interface of Cisco Security Manager could allow an unauthenticated, remote attacker to conduct cross-site scripting attacks against a user of the interface. These vulnerabilities are due to insufficient validation of user-supplied input by the web-based management interface. An attacker could exploit these vulnerabilities by persuading a user to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the interface or access sensitive, browser-based information.
