| 标题 | H2O-3 latest Pre-Auth Insecure Deserialization |
|---|
| 描述 | H2O-3 contains a pre-auth insecure deserialization vulnerability in binary model import. An unauthenticated attacker can upload a malicious JAR, embed a custom_metric_func reference into a model, export the model, and later re-import it so that the malicious reference is restored from serialized bytes. When the imported model is scored, H2O-3 loads the attacker-controlled JAR from DKV and executes the referenced class, resulting in unauthenticated remote code execution in the server JVM. |
