We then merge the newly created schema with the existing schema.
We parse the GraphQL query into an AST and then create a schema based on it. This function takes an existing schema (basically empty at first) and the GraphQL query. This section describes our approach to building a GraphQL schema using queries sent through Burp Suite.Įvery GraphQL query that goes through Burp Suite gets sent to a query transformer function we built using graphql-java. The application had introspection enabled by default, but we just assumed that it didn't. We tested this against a local Go application called Traggo.
The following video demonstrates GraphQuail building a schema for a GraphQL API with introspection disabled. As a result, GraphQuail shows all queries, arguments, and fields available for use within the API. The extension returns a fake response when it receives an introspection query. The extension also exposes GraphiQL and Voyager. This extension observes GraphQL API requests going through Burp and builds an internal GraphQL schema with each new query it sees. I included this functionality as part of our Burp Suite extension, GraphQuail.

After some trial and error, I developed a practical approach to do just that. Having a GraphQL schema is a considerable improvement over working with raw HTTP requests. If I could do this, it would let anyone interact with a GraphQL API through GraphiQL even without having the schema. I wondered if it would be possible to passively observe traffic and piece together a GraphQL schema based on the queries that went through Burp Suite. Otherwise, you could point GraphiQL (or similar tools) to the GraphQL endpoint and have a fully populated schema to aid the construction of queries. This is only an issue if introspection is disabled. It also doesn't make much sense to test GraphQL endpoints by manipulating raw HTTP requests, and it's much more suitable to use tools like GraphiQL. You would need to spend a lot of time reviewing each request to determine queries, arguments, and fields. This isn't fun to look at, but more importantly, getting the coverage you need isn't feasible. Anyone who has reviewed a GraphQL API will have seen many requests that look something like this: Now, open your browser and check whether the HTTP traffic goes through burp or not.One of the main obstacles of a black box GraphQL security review is getting good coverage of the exposed functionality. If your network uses a proxy server, enter the proxy details in Options -> Upstream Proxy Servers. In Binding -> Bind to Address, select All Interfaces. Go to Proxy-> Options -> Proxy Listeners.Enter the IP and port number of the system on which Burp is running or 127.0.0.1 if the burp is running on the same machine in Proxy and Port fields respectively.

Here are the steps to set up Burp Proxy for android virtual device: Burp Suite is a very effective HTTP traffic analysis tool. The first level of android app penetration testing is HTTP traffic analysis as we do for typical web applications.
