![]() ![]() Then use the –skip flag to exclude it from the findings. # sobelow_skip def d_get_fruit ( min_q ) do To prevent this function from showing up in findings, add the following comment in lib/basket/goods.ex. Two functions were reported vulnerable to SQL injection, but d_get_fruit/1 is not vulnerable. SQL.Query: SQL injection - Low Confidence Lib/basket_web/controllers/page_controller.ex defmodule BasketWeb.PageController do use BasketWeb, :controller alias Basket.Goods def basket_a ( conn, % ] end basket % mix deps.getĬonfig.CSP: Missing Content-Security-Policy - High ConfidenceĬonfig.HTTPS: HTTPS Not Enabled - High Confidence (1) sum () returns Decimal value in case of mysql. I just divided problems into small parts. The controller action gets the min_q parameter and passes it to a_get_fruit/1. I figured out how to treat raw SQL with Ecto. Lib/basket/goods.ex defmodule Basket.Goods do import Ecto.Query alias Basket.Repo alias Basket.Fruit def a_get_fruit ( min_q ) do from ( f in Fruit, where : f. Does anyone has any idea what is making this error Thanks. The function a_get_fruit/1 is used by the controller to execute the database query, where min_q is user supplied input. This are the versions that Im using: Elixir: 1.13 ectosql: 3.7.2 postgrex: 0.16.2. Only fruit with secret set to false should be displayed. There is one location for user input, the min_q URL parameter, which is used by the database (Postgres) to display fruits. It has several types of fruit stored in the database, with a quantity integer and secret boolean value for each. To demonstrate SQL injection, we use a simple Phoenix application. This article will show secure and insecure Ecto code, how to perform an SQL injection attack, and how to use Sobelow to scan an Elixir codebase to detect this vulnerability. However, Ecto also gives you the power to construct raw SQL queries yourself, a feature that may lead to an SQL injection vulnerability being introduced. What Ive replicated in Elixir/Ecto throws an (Protocol.UndefinedError) protocol Ecto.Queryable not implemented for Transaction. The goal is to return what is in unique between the two queries. Let's go ahead and run the following: mix -r Joins. If I am connected to the same database and leave it out of the schema with just a schema prefix of dbo or even without, the schema works fine. I have an SQL query that using the PostgreSQL WITH AS to act as an XOR or 'Not' Left Join. Fortunately, Ecto comes with a mix task which will generate the repo for us. Where min_quantity is untrusted user input, is not vulnerable to SQL injection, because Ecto knows how to safely handle external data. mix deps.get In Ecto, all communication between our application and the database happens through a module called Repo. For example, the Ecto query from f in Fruit, where : f. When used correctly, Ecto prevents SQL injection due to the way queries are constructed. We were used to achieve this by restarting Postgrex but that would restart the connections which in turn triggers a race condition as seen on elixir-ecto119. defmodule BoardApi.Board do use Ecto. ![]() This is a really neat example of how extensible Ecto really is. , and then those parameters are passed in a list using the third argument of the function call. And in the module you want to use it: defmodule MyApp.Logic do import Ecto.Query import MyApp.QueryAPI def regsearch (term) do > where ( s, iregex (s.name, term)) > () end end. The SQL statement can have numerical variables such as 1, 2. Most Phoenix applications use Ecto, a database wrapper and query generator for Elixir. Whenever a migration adds an extension, we have to restart connections so they rebootstrap. Youre looking for the documentation for /4. This can be the disclosure of sensitive data, modification of the database, or deletion of entire tables. TestRepo.all(from(t in Tag, where: t.SQL injection is a type of attack against a web application, where some malicious input is parsed by the underlying database, resulting in an unauthorized operation being performed. TestRepo.update_all(from(t in Tag, where: t.uuids = ^), set: ]) ![]() This will wrap both the dumped and the casted values in a `%)) I can make the SQL above work using a fragment, which sort of seems to defeat the point of Ecto here. The idea is to have the adapter dumpers specify whether they want to keep the casted value for a parameter. There is a compan … ion PR in ecto_sql that would have to be merged after this one. ![]()
