GHSA-3m5q-q39v-xf8f: 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
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}';`,
);
[...]

Nocodb is an open source Airtable alternative. Affected versions of nocodb contain a SQL injection vulnerability, that allows an authenticated attacker with creator access to query the underlying database. By supplying a specially crafted payload to the given an attacker can inject arbitrary SQL queries to be executed. Since this is a blind SQL injection, 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. This vulnerability has been addressed in version 0.111.0. Users are advised to upgrade. There are no known workarounds for this vulnerability. This issue is also tracked as `GHSL-2023-141`.
