Unauthenticated code execution via H2 INIT directive
Published Sep 24, 2025 · Updated Sep 24, 2025
Command injection in Datart 1.0.0-rc.3 allows remote attackers to execute arbitrary code through a crafted H2 JDBC connection URL. The /api/v1/data-provider/test endpoint passes the supplied URL to H2, whose INIT directive creates and calls a Java alias that invokes Runtime.exec. No authentication or user interaction is required, and successful exploitation runs operating-system commands with the Datart server process's privileges.
