The vulnerability is due to improper checks on parameter values within affected pages. An attacker could exploit this vulnerability by persuading a user to follow a crafted link that is designed to pass HTML code into an affected parameter. A successful exploit could allow the attacker to alter the contents of a web page to redirect the user to potentially malicious web sites, or the attacker could leverage this vulnerability to conduct further client-side attacks." }, { "lang": "es", "value": "Una vulnerabilidad en determinadas p\u00e1ginas web de Cisco Webex Meetings y Cisco Webex Meetings Server podr\u00eda permitir a un atacante remoto no autenticado modificar una p\u00e1gina web en el contexto de un navegador.
