nocodb SQL Injection vulnerability

Summary

Nocodb contains SQL injection vulnerability, that allows an authenticated attacker with creator access to query the underlying database.

Product

nocodb/nocodb

Tested Version

0.109.2

Details

SQL injection in SqliteClient.ts (GHSL-2023-141)

By supplying a specially crafted payload to the given below parameter and endpoint, an attacker can inject arbitrary SQL queries to be executed. Since this is a blind SQL injections, an attacker may need to use time-based payloads which would include a function to delay execution for a given number of seconds. The response time indicates, whether the result of the query execution was true or false. Depending on the result, the HTTP response will be returned after a given number of seconds, indicating TRUE, or immediately, indicating FALSE. In that way, an attacker can reveal the data present in the database.

The triggerList method creates a SQL query using the user-controlled table_name parameter value from the tableCreate endpoint.

async triggerList(args: any = {}) {
  const _func = this.triggerList.name;
  const result = new Result();
  log.api(`${_func}:args:`, args);

  try {
    args.databaseName = this.connectionConfig.connection.database;

    const response = await this.sqlClient.raw(
      `select *, name as trigger_name from sqlite_master where type = 'trigger' and tbl_name='${args.tn}';`,
    );
[...]
