Descriptions

A vulnerability in the REST API of Cisco Firepower Device Manager (FDM) On-Box Software could allow an authenticated, remote attacker to execute arbitrary code on the underlying operating system of an affected device. This vulnerability is due to insufficient sanitization of user input on specific REST API commands. An attacker could exploit this vulnerability by sending a crafted HTTP request to the API subsystem of an affected device. A successful exploit could allow the attacker to execute arbitrary code on the underlying operating system. To exploit this vulnerability, an attacker would need valid low-privileged user credentials.

Una vulnerabilidad en la API REST del Software Cisco Firepower Device Manager (FDM) On-Box, podría permitir a un atacante remoto autenticado ejecutar código arbitrario en el sistema operativo subyacente de un dispositivo afectado. Esta vulnerabilidad es debido a un saneamiento de entrada del usuario en comandos específicos de la API REST. Un atacante podría explotar esta vulnerabilidad mediante el envío de una petición HTTP diseñada al subsistema API de un dispositivo afectado. Una explotación con éxito podría permitir a un atacante ejecutar código arbitrario en el sistema operativo subyacente. Para explotar esta vulnerabilidad, un atacante necesitaría credenciales válidas de usuario con pocos privilegios
