CVE-2015-9244: SQL Injection in mysql

Background

The mysql package is an npm package that provides a MySQL client for Node.js applications. It allows developers to interact with MySQL databases using JavaScript. The package is widely used in Node.js projects for database operations.

Vulnerability Detail

Versions of mysql prior to 2.0.0-alpha8 are affected by a SQL Injection vulnerability in the mysql.escape() function. This vulnerability arises due to improper escaping of object keys. An attacker can exploit this vulnerability by injecting malicious SQL queries through unescaped object keys, potentially leading to unauthorized access, data manipulation, or other malicious activities.

npm install mysql@2.0.0-alpha8

Workaround

There is no specific workaround mentioned for this vulnerability. However, developers can manually sanitize and escape object keys before passing them to the mysql.escape() function to prevent SQL Injection attacks. Here is an example of how to sanitize object keys using the mysql.escapeId() function:

const mysql = require('mysql');

const obj = {
  'key1': 'value1',
  'key2': 'value2',
  'key3': 'value3'
};

const sanitizedObj = {};

for (const key in obj) {
  if (Object.prototype.hasOwnProperty.call(obj, key)) {
    sanitizedObj[mysql.escapeId(key)] = obj[key];
  }
}

console.log(sanitizedObj);

Conclusion

The SQL Injection vulnerability in the mysql package prior to version 2.0.0-alpha8 can lead to unauthorized access, data manipulation, or other malicious activities on the MySQL database. It is crucial to update to the latest version to mitigate this vulnerability. For further support on vulnerability remediation, you can reach out to DevNack.com.
