      "value": "A vulnerability in the web UI of Cisco Firepower Management Center (FMC) Software could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of the FMC Software. The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface. An attacker could exploit this vulnerability by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the interface or to access sensitive, browser-based information."

      "value": "Una vulnerabilidad en la Interfaz de Usuario web del Cisco Firepower Management Center (FMC) Software, podr\u00eda permitir a un atacante remoto no autenticado conducir un ataque de tipo cross-site scripting (XSS) contra un usuario de la interfaz de administraci\u00f3n basada en web del software FMC. La vulnerabilidad es debido a una comprobaci\u00f3n insuficiente de una entrada suministrada por el usuario mediante la interfaz de administraci\u00f3n basada en web. Un atacante podr\u00eda explotar esta vulnerabilidad al persuadir a un usuario de la interfaz para que haga clic en un enlace dise\u00f1ado. Una explotaci\u00f3n con \u00e9xito podr\u00eda permitir a un atacante ejecutar c\u00f3digo de script arbitrario en el contexto de la interfaz o acceder a informaci\u00f3n confidencial basada en navegador."
