Descriptions

A vulnerability in the authentication component of Cisco Webex Meetings could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based interface. This vulnerability is due to insufficient validation of user-supplied input by the web-based interface of the authentication component of Cisco Webex Meetings. An attacker could exploit this vulnerability by persuading a user of the interface to click a maliciously crafted 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 el componente de autenticación de Cisco Webex Meetings podría permitir a un atacante remoto no autenticado conducir un ataque de tipo cross-site scripting (XSS) contra un usuario de la interfaz basada en la web. Esta vulnerabilidad es debido a que la interfaz basada en la web del componente de autenticación de Cisco Webex Meetings no comprueba suficientemente las entradas proporcionadas por el usuario. Un atacante podría explotar esta vulnerabilidad al convencer a un usuario de la interfaz para que haga clic en un enlace diseñado de forma maliciosa. Una explotación con éxito podría permitir al atacante ejecutar código de script arbitrario en el contexto de la interfaz afectada o acceder a información confidencial basada en el navegador
