CVE-2024-10553Public exploitNetwork attack vector

Unauthenticated code execution via unvalidated JDBC URLs

Published Mar 20, 2025 · Updated Mar 20, 2025

Deserialization in H2O-3 before 3.47.0 allows remote attackers to execute arbitrary code through unauthenticated REST requests. SQLManager passes user-controlled JDBC URLs from ImportSQLTable and SaveToHiveTable to DriverManager without rejecting dangerous driver parameters. Successful exploitation requires a MySQL or PostgreSQL JDBC driver on the classpath and runs code with the H2O-3 process's privileges.
