Descriptions

Multiple vulnerabilities in the web-based management interface of Cisco Firepower Management Center (FMC) could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the interface of an affected system. The vulnerabilities exist because the web-based management interface does not properly validate user-supplied input. An attacker could exploit these vulnerabilities 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 affected interface or access sensitive, browser-based information.

Múltiples vulnerabilidades en la interfaz de administración basada en web de Cisco Firepower Management Center (FMC), podrían permitir a un atacante remoto autenticado llevar a cabo un ataque de tipo cross-site scripting (XSS) almacenado contra un usuario de la interfaz de un sistema afectado. Las vulnerabilidades se presentan porque la interfaz de administración basada en web no comprueba apropiadamente la entrada suministrada por el usuario. Un atacante podría explotar estas vulnerabilidades persuadiendo a un usuario de la interfaz para que haga clic en un enlace diseñado. Una explotación con éxito podría permitir al atacante ejecutar código de script arbitrario en el contexto de la interfaz afectada o acceder a información confidencial basada en el navegador.
