Name of the Vulnerable Software and Affected Versions h2oai/h2o-3 version 3.46.0

Description 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 issue 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.

Recommendations For h2oai/h2o-3 version 3.46.0, consider restricting access to the model export endpoint until a patch is available. As a temporary workaround, restrict the export location to a specific directory to minimize the risk of exploitation.
