MariaDB Connector/J is used to connect applications developed in Java to MariaDB and MySQL databases. From 3.0.0 until 3.3.7, 3.4.5, and 3.5.11, the ClientMessage.validateLocalFileName() check used a regular expression that could match LOAD DATA LOCAL INFILE text inside quoted identifiers, string literals, or comments instead of requiring a real statement. A malicious or compromised server, or a machine-in-the-middle attacker, could return crafted database or table identifiers that the connector reused in metadata or updatable-result queries, then answer with a LOCAL INFILE request for a client file. With allowLocalInfile enabled, this caused the connector to stream any readable client-host file named by the crafted text, including through DatabaseMetaData.getImportedKeys(), DatabaseMetaData.getExportedKeys(), or ResultSet.updateRow() paths. This issue is fixed in versions 3.3.7, 3.4.5, and 3.5.11.
