In Fleet before version 3.7.0 a malicious actor with a valid node key can send a badly formatted request that causes the Fleet server to exit, resulting in denial of service. This is possible only while a live query is currently ongoing. We believe the impact of this vulnerability to be low given the requirement that the actor has a valid node key. There is no information disclosure, privilege escalation, or code execution. The issue is fixed in Fleet 3.7.0." } ] }, "impact": { "cvss": { "attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "LOW", "baseScore": 2.7, "baseSeverity": "LOW", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "privilegesRequired": "HIGH", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:L", "version": "3.1" } }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "CWE-400 Uncontrolled Resource Consumption" } ] } ] }, "references": { "reference_data": [ { "name": "https://github.com/fleetdm/fleet/security/advisories/GHSA-xwh8-9p3f-3x45", "refsource": "CONFIRM", "url": "https://github.com/fleetdm/fleet/security/advisories/GHSA-xwh8-9p3f-3x45" }, { "name": "https://www.npmjs.com/package/fleetctl", "refsource": "MISC", "url": "https://www.npmjs.com/package/fleetctl" }, { "name": "https://github.com/fleetdm/fleet/commit/f68f4238e83b45b2164e4ed05df14af0f06eaf40", "refsource": "MISC", "url": "https://github.com/fleetdm/fleet/commit/f68f4238e83b45b2164e4ed05df14af0f06eaf40" } ] }, "source": { "advisory": "GHSA-xwh8-9p3f-3x45", "discovery": "UNKNOWN" } }
