Descriptions

Multiple vulnerabilities in the multi-instance feature of Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, local attacker to escape the container for their FTD instance and execute commands with root privileges in the host namespace. These vulnerabilities are due to insufficient protections on the underlying filesystem. An attacker could exploit these vulnerabilities by modifying critical files on the underlying filesystem. A successful exploit could allow the attacker to execute commands with root privileges within the host namespace. This could allow the attacker to impact other running FTD instances.

Múltiples vulnerabilidades en la funcionalidad de múltiples instancias del Software Cisco Firepower Threat Defense (FTD), podrían permitir a un atacante local autenticado escapar del contenedor para su instancia FTD y ejecutar comandos con privilegios de root en el espacio de nombres del host. Estas vulnerabilidades son debido a protecciones insuficientes en el sistema de archivos subyacente. Un atacante podría explotar estas vulnerabilidades mediante la modificación de archivos críticos en el sistema de archivos subyacente. Una explotación con éxito podría permitir al atacante ejecutar comandos con privilegios de root dentro del espacio de nombres del host. Esto podría permitir al atacante afectar otras instancias de FTD en ejecución.
