This vulnerability is due to insufficient validation of values in Webex recording files that are in Webex Recording Format (WRF). An attacker could exploit this vulnerability by sending a user a malicious WRF file through a link or email attachment and persuading the user to open the file with the affected software on the local system. A successful exploit could allow the attacker to execute arbitrary code on the affected system with the privileges of the targeted user."},{"lang":"es","value":"Una vulnerabilidad en Cisco Webex Player para Windows y MacOS podría permitir a un atacante ejecutar código arbitrario en un sistema afectado. Esta vulnerabilidad es debido a una comprobación insuficiente de los valores en los archivos de grabación de Webex que están en Webex Recording Format (WRF). Un atacante podría explotar esta vulnerabilidad mediante el envío de un usuario a abrir un archivo WRF malicioso mediante un enlace o un archivo adjunto de correo electrónico y convenciendo al usuario de que abra el archivo con el software afectado en el sistema local.
