CVE-2026-33906

Full vulnerability record from the local CVENow database.

Description

Ella Core is a 5G core designed for private networks. Prior to version 1.7.0, the NetworkManager role was granted backup and restore permission. The restore endpoint accepted any valid SQLite file without verifying its contents. A NetworkManager could replace the production database with a tampered copy to escalate to Admin, gaining access to user management, audit logs, debug endpoints, and operator identity configuration that the role was explicitly denied. In version 1.7.0, backup and restore permissions have been removed from the NetworkManager role.

El endpoint de restauración aceptaba cualquier archivo SQLite válido sin verificar su contenido. Un NetworkManager podía reemplazar la base de datos de producción con una copia manipulada para escalar a Administrador, obteniendo acceso a la gestión de usuarios, registros de auditoría, endpoints de depuración y configuración de identidad del operador que le fue explícitamente denegado al rol. En la versión 1.7.0, los permisos de copia de seguridad y restauración han sido eliminados del rol de NetworkManager."
