Descriptions

A vulnerability in an API of Cisco Webex Meetings could allow an unauthenticated, remote attacker to conduct cross-site scripting attacks. The vulnerability is due to improper validation of user-supplied input to an application programmatic interface (API) within Cisco Webex Meetings. An attacker could exploit this vulnerability by convincing a targeted user to follow a link designed to submit malicious input to the API used by Cisco Webex Meetings. A successful exploit could allow the attacker to conduct cross-site scripting attacks and potentially gain access to sensitive browser-based information from the system of a targeted user.

Una vulnerabilidad en una API de Cisco Webex Meetings, podría permitir a un atacante remoto no autenticado conducir ataques de tipo cross-site scripting. La vulnerabilidad es debido a una comprobación inapropiada de la entrada suministrada por el usuario a una interfaz de programación de aplicaciones (API) dentro de Cisco Webex Meetings. Un atacante podría explotar esta vulnerabilidad convenciendo a un usuario objetivo de que siga un vínculo diseñado para enviar información maliciosa a la API utilizada por Cisco Webex Meetings. Una explotación con éxito podría permitir al atacante conducir ataques de tipo cross-site scripting y potencialmente conseguir acceso a información confidencial basada en navegador del sistema de un usuario apuntado
