CVE-2024-6960
H2O vulnerable to Deserialization of Untrusted Data
7.5
HIGH
CVSS 3.1
EPSS 0.18%
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.
