CVSS 3.0
7.1 highCVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:HCVE-2024-6854
High (7.1) in h2o h2o. EPSS 0.8% chance of exploitation in the next 30 days.
In h2oai/h2o-3 version 3.46.0, the endpoint for exporting models does not restrict the export location, allowing an attacker to export a model to any file in the server's file structure, thereby overwriting it. This vulnerability can be exploited to overwrite any file on the target server with a trained model file, although the content of the overwrite is not controllable by the attacker.
