Fleet 是一个基于 osquery 构建的开源设备管理平台。在 4.84.1 及之前版本中，Apple MDM 命令列表端点（GET /api/v1/fleet/mdm/apple/commands）允许拥有最低权限的 Observer 角色的已认证用户，通过“排序顺序预言机”（sort-order oracle）从关联的数据库表中提取敏感值，包括主机注册密钥（host enrollment secrets）和 Apple 推送通知服务（APNs）令牌。 该端点接受用户提供的 参数，但该参数未根据列白名单进行校

Vulnerability Title
Fleet: Observer-level enrollment secret extraction via ORDER BY oracle on Apple MDM commands endpoint
来源: CVE Program / CVE List V5
Vulnerability Description
Fleet is an open-source device management platform built on osquery. In versions up to and including 4.84.1, the Apple MDM commands listing endpoint (GET /api/v1/fleet/mdm/apple/commands) allowed an authenticated user with the lowest-privilege Observer role to extract sensitive values from joined database tables, including host enrollment secrets and Apple Push Notification Service tokens, through a sort-order oracle. The endpoint accepted a user-supplied order_key parameter that was not validated against a column allowlist, and because the underlying query joins the hosts and nano_enrollments tables, an attacker could set the sort column to a sensitive field and combine it with the cursor-based after parameter to binary-search the value one character at a time, with the presence or absence of results revealing each character even though the value never appeared in the response. With extracted node_key or orbit_node_key values an attacker could impersonate enrolled hosts to Fleet's osquery and Orbit endpoints, submit fabricated host data, and retrieve pending scripts and commands. This issue is fixed in version 4.84.2.
