CVE-2023-43794: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in nocodb

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}';\`,
);
