PT-2025-35547

Name of the Vulnerable Software and Affected Versions: H2O-3 versions prior to 3.46.0.8 Description: A deserialization issue exists in the H2O-3 REST API /99/ImportSQLTable. The vulnerability allows remote code execution RCE due to improper validation of JDBC connection parameters when using a...

GHSA-H7XG-CMPP-48HF H2O Deserialization of Untrusted Data Vulnerability

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...

H2O.ai H2O vulnerable to deserialization attacks via a JDBC Connection URL

H2O.ai H2O through 3.46.0.4 allows attackers to arbitrarily set the JDBC URL, leading to deserialization attacks, file reads, and command execution. Exploitation can occur when an attacker has access to post to the ImportSQLTable URI with a JSON document containing a connectionurl property with a...

Deserialization of Untrusted Data

Overview Affected versions of this package are vulnerable to Deserialization of Untrusted Data via the ImportSQLTable process when an attacker submits a JSON document containing a crafted connectionurl property. An attacker can execute arbitrary commands and read files by supplying a malicious JD...
