The vulnerability exists due to insufficient validation of certain elements with a Webex recording stored in either the Advanced Recording Format (ARF) or the Webex Recording Format (WRF). An attacker could exploit this vulnerability by sending a user a malicious ARF or 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 cause the Webex player application to crash when trying to view the malicious file." }, { "lang": "es", "value": "Una vulnerabilidad en Cisco Webex Network Recording Player y Cisco Webex Player para Microsoft Windows, podr\u00eda permitir a un atacante causar un bloqueo del proceso resultando en una condici\u00f3n de Denegaci\u00f3n de servicio (DoS) para la aplicaci\u00f3n del reproductor en un sistema afectado. La vulnerabilidad se presenta debido a una comprobaci\u00f3n insuficiente de determinados elementos con una grabaci\u00f3n de Webex almacenada en el Advanced Recording Format (ARF) o en el Webex Recording Format (WRF).
