Ensure `local_infile` Is Disabled

TinggiLevel 1Otomatistdsql

Deskripsi

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).
