Technical details
A blind SQL injection vulnerability exists in the 'GET /api/v1/fleet/labels/{id}/hosts' endpoint due to improper validation of the 'order_key' parameter. The endpoint uses a deprecated helper that fails to restrict the columns used in the ORDER BY clause, allowing an attacker to specify sensitive columns like 'node_key'. By combining this with the cursor-based 'after' parameter, an authenticated Observer can perform a binary search oracle to extract long-lived enrollment secrets character-by-character. These secrets (node_key and orbit_node_key) can be used to impersonate hosts, retrieve MDM commands, or poison inventory data. The issue is fixed in version 4.85.0 (and 4.84.2 according to some advisory metadata).
