H2O Vulnerable to Arbitrary File Overwrite via File Export
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| PyPI | h2o | >= 3.32.1.1, <= 3.46.0 | no fix listed |
| Maven | ai.h2o:h2o-core | >= 3.32.1.1, <= 3.46.0 | no fix listed |
Details
As written in the advisory (Markdown source, shown as plain text).
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.
