Ensure `local_infile` Is Disabled

高等級 1自動化tdsql

說明

The local_infile parameter controls whether clients are allowed to use the LOAD DATA LOCAL INFILE statement. Enabling this feature can be abused by an attacker to read arbitrary files on the client host through carefully crafted SQL statements. Runs the mysql client against the TDSQL data node selected by TDSQL_MYSQL_OPTS (e.g. "-h10.0.0.5 -P4001 -utdsql_audit"); keep the password in ~/.my.cnf or a login path rather than MYSQL_PWD or the command line (see 1.4 and 1.5).

Set the instance parameter local_infile = OFF through the TDSQL management platform (OSS) or SET GLOBAL local_infile = OFF; and persist it in the parameter template.
