CVE-2023-43794: 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 tablename parameter value from the tableCreate endpoint.

javascript 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 triggername from sqlitemaster where type = 'trigger' and tblname='${args.tn}';, ); [...]
