CyberRota Analysis
AI-GeneratedMariaDB Connector/Node.js versions prior to 3.2.4, 3.3.3, 3.4.6, and 3.5.3 are vulnerable to SQL injection due to improper handling of attacker-controlled Buffer parameters when using specific client character sets. Exploitation of this vulnerability can allow unauthorized access to or modification of data within the database. Organizations utilizing affected versions of the connector should prioritize upgrading to the patched versions to mitigate potential data breaches.

Original NVD Description
MariaDB Connector/Node.js is used to connect applications developed on Node.js to MariaDB and MySQL databases. Prior to 3.2.4, 3.3.3, 3.4.6, and 3.5.3, MariaDB Connector/Node.js permits SQL injection when attacker-controlled Buffer parameters are escaped client-side under the big5, gbk, sjis, cp932, or gb18030 client character sets. PacketOutputStream.writeBufferEscape in lib/io/packet-output-stream.js escaped bytes without the charset-aware getMbRecognizer logic in lib/misc/charset-mb.js. The server SQL lexer runs my_ismbchar before escape processing, so an attacker-controlled lead byte can consume the inserted 0x5C backslash as a multibyte trail byte and leave the following 0x27 quote unescaped, terminating the string literal and allowing arbitrary SQL. The default utf8mb4 character set and parameters sent through the execute binary prepared-statement path are not affected. Successful exploitation can expose or modify data available to the database account. This issue is fixed in versions 3.2.4, 3.3.3, 3.4.6, and 3.5.3.
