CVSS 3.0
8.2 highCVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:HCVE-2024-8616
High (8.2) in h2o h2o. EPSS 0.6% chance of exploitation in the next 30 days.
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.
