Descriptions

A vulnerability in the web-based management interface of Cisco Webex Events Center, Cisco Webex Meeting Center, Cisco Webex Support Center, and Cisco Webex Training Center could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of the affected service. The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of the affected service. An attacker could exploit this vulnerability by persuading a user of the interface 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.

Una vulnerabilidad en la interfaz de gestión web de Cisco Webex Events Center, Cisco Webex Meeting Center, Cisco Webex Support Center y Cisco Webex Training Center podría permitir que un atacante remoto sin autenticar lleve a cabo un ataque Cross-Site Scripting (XSS) contra un usuario de dicha interfaz en un dispositivo afectado. La vulnerabilidad se debe a la validación insuficiente de entrada de datos de parte del usuario en la interfaz de gestión web del servicio afectado. Un atacante podría explotar esta vulnerabilidad haciendo que un usuario de la interfaz haga clic en un enlace malicioso. Su explotación con éxito podría permitir al atacante ejecutar código script arbitrario en el contexto de la interfaz afectada o que pueda acceder a información sensible del navegador.
