{"id":"CVE-2024-8616","url":"https://www.cyber-defence.io/tools/cve/CVE-2024-8616","generatedAt":"2026-10-28T04:12:25.078Z","title":"In h2oai/h2o-3 version 3.46.0, the `/99/Models/{name}/json` endpoint allows for arbitrary file overwrite on the target server.","description":"In h2oai/h2o-3 version 3.46.0, the `/99/Models/{name}/json` endpoint allows for arbitrary file overwrite on the target server. The vulnerability arises from the `exportModelDetails` function in `ModelsHandler.java`, where the user-controllable `mexport.dir` parameter is used to specify the file path for writing model details. This can lead to overwriting files at arbitrary locations on the host system.","published":"2025-03-20T10:15:44.000Z","lastModified":"2026-06-17T08:22:59.000Z","status":"Analyzed","sourceIdentifier":"security@huntr.dev","cvss":{"version":"3.0","score":8.2,"severity":"HIGH","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H"},"cwe":["CWE-73"],"affected":["h2o/h2o"],"epss":{"score":0.00557,"percentile":0.46249,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.56%).
