How to Fix CVE-2024-10553

To remediate this vulnerability, upgrade all affected H2o dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

h2o fixed: 3.46.0.6 
pip install h2o>=3.46.0.6
ai.h2o:h2o-core fixed: 3.46.0.6 
<dependency>
    <groupId>ai.h2o</groupId>
    <artifactId>h2o-core</artifactId>
    <version>3.46.0.6</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show h2o

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2024-10553, inspect your installed packages using pip:

pip show h2o

Analyze the terminal output to locate any version of H2o in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.46.0.6), your application is affected.

Note: The pip show h2o command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-502: Deserialization of Untrusted Data, where the product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid. In H2o, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A vulnerability in the h2oai/h2o-3 REST API versions 3.46.0.4 allows unauthenticated remote attackers to execute arbitrary code via deserialization of untrusted data. The vulnerability exists in the endpoints POST /99/ImportSQLTable and POST /3/SaveToHiveTable, where user-controlled JDBC URLs are passed to DriverManager.getConnection, leading to deserialization if a MySQL or PostgreSQL driver is available in the classpath. This issue is fixed in version 3.46.0.6.
