CVE-2024-6960

H2O deserializes ML models without filtering, potentially allowing execution of malicious code

State: Published
Severity: 7.5 High
Published: Jul 21, 2024
Updated: Nov 25, 2024
Reserved: Jul 21, 2024

Description

The H2O machine learning platform uses "Iced" classes as the primary means of moving Java Objects around the cluster. The Iced format supports inclusion of serialized Java objects. When a model is deserialized, any class is allowed to be deserialized (no class whitelist). An attacker can construct a crafted Iced model that uses Java gadgets and leads to arbitrary code execution when imported to the H2O platform.
