Descriptions

Multiple vulnerabilities in Cisco Webex Network Recording Player for Microsoft Windows and Cisco Webex Player for Microsoft Windows could allow an attacker to execute arbitrary code on an affected system. The vulnerabilities are due to insufficient validation of certain elements within a Webex recording that is stored in either the Advanced Recording Format (ARF) or the Webex Recording Format (WRF). An attacker could exploit these vulnerabilities by sending a malicious ARF or WRF file to a user through a link or email attachment and persuading the user to open the file 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.

Múltiples vulnerabilidades en Cisco Webex Network Recording Player para Microsoft Windows y Cisco Webex Player para Microsoft Windows, podrían permitir a un atacante ejecutar código arbitrario sobre un sistema afectado. Las vulnerabilidades son debido a una comprobación insuficiente de determinados elementos dentro de una grabación de Webex que es almacenada en el Advanced Recording Format (ARF) o el Webex Recording Format (WRF). Un atacante podría explotar estas vulnerabilidades mediante el envío de un archivo ARF o WRF malicioso hacia un usuario por medio de un enlace o archivo adjunto de correo electrónico y persuadiendo al usuario para que abra el archivo en el sistema local. Una explotación con éxito podría permitir al atacante ejecutar código arbitrario en el sistema afectado con los privilegios del usuario apuntado.
