CRITICAL9.3EPSS 0.21%External Control of File Name or Path in h2oai/h2o-3
Published: 12/14/2023Modified: 4/30/2026
Description
Remote unauthenticated attackers can overwrite arbitrary server files with attacker-controllable data. The data that the attacker can control is not entirely arbitrary. h2o writes a CSV/XLS/etc file to disk, so the attacker data is wrapped in quotations and starts with "C1", if they're exporting as CSV.
