Descriptions
A vulnerability in Cisco Webex Meetings Desktop App and Webex Productivity Tools for Windows could allow an authenticated, local attacker to gain access to sensitive information on an affected system. This vulnerability is due to the unsafe usage of shared memory by the affected software. An attacker with permissions to view system memory could exploit this vulnerability by running an application on the local system that is designed to read shared memory. A successful exploit could allow the attacker to retrieve sensitive information from the shared memory, including usernames, meeting information, or authentication tokens. Note: To exploit this vulnerability, an attacker must have valid credentials on a Microsoft Windows end-user system and must log in after another user has already authenticated with Webex on the same end-user system.
Una vulnerabilidad en Cisco Webex Meetings Desktop App y Webex Productivity Tools para Windows, podría permitir a un atacante local autenticado obtener acceso a información confidencial en un sistema afectado. Esta vulnerabilidad es debido al uso no seguro de la memoria compartida por parte del software afectado. Un atacante con permisos para visualizar la memoria del sistema podría explotar esta vulnerabilidad ejecutando una aplicación en el sistema local diseñada para leer la memoria compartida. Una explotación con éxito podría permitir al atacante recuperar información confidencial de la memoria compartida, incluyendo nombres de usuario, información de reuniones o tokens de autenticación. Nota: Para aprovechar esta vulnerabilidad, un atacante debe tener credenciales válidas en un sistema de usuario final de Microsoft Windows y debe iniciar sesión después de que otro usuario ya se haya autenticado con Webex en el mismo sistema de usuario final
