CVE-2024-6854Public exploitNetwork attack vector

Arbitrary file overwrite via unrestricted export path

Published Mar 20, 2025 · Updated Mar 20, 2025

Absolute path traversal in H2O.ai H2O-3 3.46.0 allows remote authenticated users to overwrite server files through model export. The model export endpoint accepts an unrestricted destination path and writes a trained model there, replacing an existing file when overwrite is enabled. A valid low-privilege session and an existing trained model are required; file contents are limited to the exported model, but critical files can be corrupted.
