Descriptions

A vulnerability in the software update feature of Cisco Webex Meetings Desktop App for Mac could allow an unauthenticated, remote attacker to execute arbitrary code on an affected system. The vulnerability is due to improper validation of cryptographic protections on files that are downloaded by the application as part of a software update. An attacker could exploit this vulnerability by persuading a user to go to a website that returns files to the client that are similar to files that are returned from a valid Webex website. The client may fail to properly validate the cryptographic protections of the provided files before executing them as part of an update. A successful exploit could allow the attacker to execute arbitrary code on the affected system with the privileges of the user.

Una vulnerabilidad en la funcionalidad software update de Cisco Webex Meetings Desktop App para Mac, podría permitir a un atacante remoto no autenticado ejecutar código arbitrario sobre un sistema afectado. La vulnerabilidad es debido a una comprobación inapropiada de las protecciones criptográficas en los archivos que son descargados por la aplicación como parte de una actualización de software. Un atacante podría explotar esta vulnerabilidad al persuadir a un usuario para que vaya a un sitio web que devuelva archivos al cliente que son similares a los archivos que son devueltos de un sitio web válido de Webex. El cliente puede presentar un fallo al comprobar apropiadamente las protecciones criptográficas de los archivos proporcionados antes de ejecutarlos como parte de una actualización. Una explotación con éxito podría permitir a un atacante ejecutar código arbitrario sobre el sistema afectado con los privilegios del usuario
