The vulnerability arises due to insufficient security controls in the parameter blacklist mechanism, which only targets MySQL JDBC driver-specific dangerous parameters. An attacker can bypass these controls by switching the JDBC URL protocol to jdbc:postgresql: and exploiting PostgreSQL JDBC driver-specific parameters such as socketFactory and socketFactoryArg. This allows unauthenticated attackers to execute arbitrary code on the H2O-3 server with the privileges of the H2O-3 process. The issue is resolved in version 3.46.0.10."},{"lang":"es","value":"Una vulnerabilidad crítica de ejecución remota de código existe en el endpoint de API REST no autenticado /99/ImportSQLTable en H2O-3 versión 3.46.0.9 y anteriores.
