Ensure 'FILE' is Not Granted to Non-Administrative Users
HighLevel 1Manual reviewmariadb
Description
The FILE privilege is used to allow or disallow a user from reading and writing files on the server host. Any user with the FILE right granted has the ability to: ; Read files from the local file system that are readable by the MariaDB server (this includes world-readable files). ; Write files to the local file system where the MariaDB server has write access.
How it is checked
Audit method: Manual review
This recommendation cannot be checked automatically. A scan lists it with these instructions when you pass --include-manual.
Run SELECT GRANTEE FROM INFORMATION_SCHEMA.USER_PRIVILEGES WHERE PRIVILEGE_TYPE = 'FILE'; Ensure only administrative users are returned in the result set.
How it is fixed
Fix method: Guidance or infrastructure patch
REVOKE FILE ON *.* FROM '<user>'@'<host>'; for each non-administrative grantee.
