描述

## 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](https://github.com/nocodb/nocodb/releases/tag/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`](https://github.com/nocodb/nocodb/blob/3ec82824eeb2295f6b67fd67e7d6049784b41221/packages/nocodb/src/db/sql-client/lib/sqlite/SqliteClient.ts#L628-L654) method creates a SQL query using the user-controlled [`table_name`](https://github.com/nocodb/nocodb/blob/3ec82824eeb2295f6b67fd67e7d6049784b41221/packages/nocodb/src/db/sql-client/lib/sqlite/SqliteClient.ts#L637) parameter value from the [`tableCreate`](https://github.com/nocodb/nocodb/blob/3ec82824eeb2295f6b67fd67e7d6049784b41221/packages/nocodb/src/controllers/tables.controller.ts#L63) endpoint. ```javascript async triggerList(args: any = {}) { const _func = this.triggerList.name; const result = new Result(); log.api(`${_func}:args:`, args); try { args.databaseName = this.connectionConfig.connection.database; const response = await this.sqlClient.raw( `select *, name as trigger_name from sqlite_master where type = 'trigger' and tbl_name='${args.tn}';`, ); [...] ``` #### Impact This issue may lead to `Information Disclosure`. ## Credit This issue was discovered and reported by GHSL team member [@sylwia-budzynska (Sylwia Budzynska)](https://github.com/sylwia-budzynska). ## Disclosure Policy This report is subject to our [coordinated disclosure policy](https://securitylab.github.com/advisories#policy).
