This is achieved by exploiting the `/3/Parse` endpoint to inject attacker-controlled data as the header of an empty file, which is then exported using the `/3/Frames/framename/export` endpoint. The impact of this vulnerability includes the potential for remote code execution and complete access to the system running h2o-3, as attackers can overwrite critical files such as private SSH keys or script files."}],"affected":[{"vendor":"h2oai","product":"h2oai/h2o-3","versions":[{"version":"unspecified","status":"affected","versionType":"custom","lessThanOrEqual":"latest"}]}],"references":[{"url":"https://huntr.com/bounties/64ff5319-6ac3-4447-87f7-b53495d4d5a3"}],"metrics":[{"cvssV3_0":{"version":"3.0","attackComplexity":"LOW","attackVector":"NETWORK","availabilityImpact":"HIGH","confidentialityImpact":"NONE","integrityImpact":"HIGH","privilegesRequired":"NONE","scope":"UNCHANGED","userInteraction":"NONE","vectorString":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","baseScore":9.1,"baseSeverity":"CRITICAL"}}],"problemTypes":[{"descriptions":[{"type":"CWE","lang":"en","description":"CWE-73 External Control of File Name or Path","cweId":"CWE-73"}]}],"source":{"advisory":"64ff5319-6ac3-4447-87f7-b53495d4d5a3","discovery":"EXTERNAL"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-02-02T12:52:10.722874Z","id":"CVE-2024-5986","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-02-02T13:13:23.762Z"}}]}}
