CyberRota Analysis
AI-GeneratedThe Fleet device management platform is vulnerable in versions up to 4.84.1, allowing authenticated users with the Observer role to exploit the host-listing endpoint and extract sensitive host enrollment secrets through an unvalidated sort-order parameter. This could enable attackers to impersonate enrolled hosts, submit false data, and manipulate compliance and policy results. Organizations using Fleet, particularly those with users assigned the Observer role, should prioritize upgrading to version 4.84.2 to mitigate this risk.

Original NVD 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.
