Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Fleet 是一个基于 osquery 构建的开源设备管理平台。在截至 4.84.1 版本中，标签主机列表接口（GET /api/v1/fleet/labels/{id}/hosts）允许拥有最低权限“观察者（Observer）”角色的已认证用户，通过一种“排序顺序预言机（sort-order oracle）”提取主机注册密钥。 该接口接受用户提供的 参数，且未将其与列名白名单进行校验。因此，拥有全局（Global）或团队（Team）观察者权限的攻击者可以将排序列设置为敏感字段（如 ），并结合基于游标（cursor

Vulnerability Title
Fleet has observer-level enrollment secret extraction via ORDER BY oracle on labels host-listing endpoint
Source: 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 labels host-listing endpoint (GET /api/v1/fleet/labels/{id}/hosts) allowed an authenticated user with the lowest-privilege Observer role to extract host enrollment secrets through a sort-order oracle. The endpoint accepted a user-supplied order_key parameter that was not validated against a column allowlist, so an attacker with Global or Team Observer access could set the sort column to a sensitive field such as h.node_key and combine it with the cursor-based after parameter to binary-search the value one character at a time; the targeted value never appeared in the response, but the presence or absence of results revealed each character. Because node_key and orbit_node_key are the long-lived shared secrets that osquery and Orbit agents use to authenticate to the Fleet server, an attacker who reconstructed them could impersonate enrolled hosts, submit fabricated query results and inventory, retrieve pending scripts and MDM commands, and poison compliance and policy results across the deployment. This issue is fixed in version 4.84.2.
