This issue stems from the /etc/passwd file being created with group-writable permissions during build time. In certain conditions, an attacker who can execute commands within an affected container, even as a non-root user, can leverage their membership in the root group to modify the /etc/passwd file. This could allow the attacker to add a new user with any arbitrary UID, including UID 0, leading to full root privileges within the container"},{"lang":"es","value":"Se encontró una falla de escalada de privilegios de contenedor en ciertas imágenes de Multi-Cloud Object Gateway Core. Este problema se origina en la creación del archivo /etc /passwd con permisos de escritura para el grupo durante el tiempo de compilación. En ciertas condiciones, un atacante que puede ejecutar comandos dentro de un contenedor afectado, incluso como un usuario no-root, puede aprovechar su pertenencia al grupo root para modificar el archivo /etc /passwd.
