CyberRota Analysis
AI-GeneratedThe MariaDB Connector/Node.js versions prior to 3.3.3, 3.4.6, and 3.5.3 are vulnerable when SSL is enabled without a pinned CA or server certificate, allowing credentials to be sent before completing certificate validation. This flaw can be exploited by an active man-in-the-middle attacker who presents a self-signed certificate, potentially capturing database passwords for unauthorized access. Organizations using affected versions of the connector should prioritize upgrading to the fixed versions to mitigate this high-severity risk.

Original NVD Description
MariaDB Connector/Node.js is used to connect applications developed on Node.js to MariaDB and MySQL databases. Prior to versions 3.3.3, 3.4.6, and 3.5.3, when ssl is enabled without a pinned CA or server certificate, MariaDB Connector/Node.js sends credentials before completing certificate fingerprint validation. In lib/cmd/handshake/auth/handshake.js, a server that selects mysql_clear_password as the initial authentication plugin can receive the password before the post-TLS identity check. In lib/cmd/handshake/authentication.js, an authentication switch can evaluate the previous plugin instead of the requested target plugin, allowing mysql_clear_password to send the credential first. An active man-in-the-middle can present a self-signed certificate, capture the database password, and use it to authenticate directly even though the connector later rejects the server and closes the connection. This issue is fixed in versions 3.3.3, 3.4.6, and 3.5.3.
