6.1.3 Ensure That the 'Local_infile' Database Flag for a Cloud SQL MySQL Instance Is Set to 'Off' (Automated)
Profile Applicability
Description
It is recommended to set the local_infile database flag for a Cloud SQL MySQL instance to off.
Rationale
The local_infile flag controls the server-side LOCAL capability for LOAD DATA statements. Depending on the local_infile setting, the server refuses or permits local data loading by clients that have LOCAL enabled on the client side.
To explicitly cause the server to refuse LOAD DATA LOCAL statements (regardless of how client programs and libraries are configured at build time or runtime), start mysqld with local_infile disabled. local_infile can also be set at runtime.
Due to security issues associated with the local_infile flag, it is recommended to disable it. This recommendation is applicable to MySQL database instances.
Impact
Disabling local_infile makes the server refuse local data loading by clients that have LOCAL enabled on the client side.
Audit
From Google Cloud Console
- Go to the Cloud SQL Instances page in the Google Cloud Console by visiting https://console.cloud.google.com/sql/instances.
- Select the instance to open its
Instance Overview page
- Ensure the database flag
local_infile that has been set is listed under the Database flags section.
From Google Cloud CLI
- List all Cloud SQL database instances:
gcloud sql instances list
- Ensure the below command returns
off for every Cloud SQL MySQL database instance.
gcloud sql instances describe <INSTANCE_NAME> --format=json | jq '.settings.databaseFlags[] | select(.name=="local_infile")|.value'
Remediation
From Google Cloud Console
- Go to the Cloud SQL Instances page in the Google Cloud Console by visiting https://console.cloud.google.com/sql/instances.
- Select the MySQL instance where the database flag needs to be enabled.
- Click
Edit.
- Scroll down to the
Flags section.
- To set a flag that has not been set on the instance before, click , choose the flag from the drop-down menu, and set its value to .
