Attackers can craft a forged JWT signed with the hardcoded secret value, specifying ssh_user=root, to authenticate to the terminal service without any valid credentials and receive a root shell."

Los atacantes pueden crear un JWT forjado firmado con el valor secreto codificado de forma rígida, especificando ssh_user=root, para autenticarse en el servicio de terminal sin credenciales válidas y recibir un shell root."
