The vulnerability is due to insufficient permission restrictions on a specific process. An attacker could exploit this vulnerability by logging in to an affected device with remote support credentials and initiating the specific process on the device and sending crafted data to that process. A successful exploit could allow the attacker to write files to the underlying file system with root privileges."},{"lang":"es","value":"Una vulnerabilidad en el software Cisco RoomOS podría permitir que un atacante local autenticado escriba archivos en el sistema de archivos subyacente con privilegios de root. La vulnerabilidad se debe a restricciones de permisos insuficientes en un proceso específico. Un atacante podría aprovechar esta vulnerabilidad iniciando sesión en un dispositivo afectado con credenciales de soporte remoto e iniciando el proceso específico en el dispositivo y enviando datos diseñados a ese proceso.
