The vulnerability is due to a lack of validation of the SSL server certificate received when establishing a connection to a Cisco Webex video device or a Cisco collaboration endpoint. An attacker could exploit this vulnerability by using man in the middle (MITM) techniques to intercept the traffic between the affected client and an endpoint, and then using a forged certificate to impersonate the endpoint. Depending on the configuration of the endpoint, an exploit could allow the attacker to view presentation content shared on it, modify any content being presented by the victim, or have access to call controls. This vulnerability does not affect cloud registered collaboration endpoints."}, {"lang": "es", "value": "Una vulnerabilidad en la implementaci\u00f3n SSL de la soluci\u00f3n Cisco Intelligent Proximity, podr\u00eda permitir a un atacante remoto no autenticado visualizar o modificar la informaci\u00f3n compartida en los dispositivos de video Cisco Webex y los endpoints de colaboraci\u00f3n de Cisco si los productos cumplen con las condiciones descritas en la secci\u00f3n de Productos Vulnerables.
