For those who don’t know, Facebook developed GraphQL, an API query language and runtime that is now open-source (relief).
Like all software, GraphQL has advantages and disadvantages of its own.
Cons pertaining to features or functionality may be disregarded. What if I told you that GraphQL has a list of security flaws?
Do not fret. You can find and address GraphQL security flaws using a number of tools.
But first, let’s look at what GraphQL is and what its weaknesses are before I introduce you to the tools.
What is GraphQL?
Think of yourself as a customer ordering lunch at a restaurant as an example of GraphQL.
You might not, however, want the exact dish that is listed on the menu. You might occasionally want to add or take away some ingredients. Let’s say you want to alter the food to your liking because you are allergic to nuts.
Consider GraphQL as a waiter who delivers exactly what you ordered after customizing it, but GraphQL operates on server-side data.
Modern applications can get you specific data using this technology, saving you a lot of bandwidth and enhancing the user experience.
Vulnerabilities of GraphQL
Here is a list of potential vulnerabilities that could be exploited by those with nefarious motives to access private data.
- Over-fetching and under-fetching: This flaw has the potential to overuse server resources. It is possible to over-fetch (get more data than requested) or under-fetch (get less data than asked and force the user to request data multiple times) data from GraphQL if the instructions for doing so are incorrect.
- Excessive data exposure: The crucial data is exposed when the access control is configured incorrectly. And if the server permits unauthorized access, any skilled hacker can easily access the data.
- Nested queries issue: You can ship complex queries because by default there is no complexity limit. Consider nested complex queries that will consume all system resources, causing sluggish response times and even the possibility of a DOS (Denial of Service) attack.
- Injections: Since GraphQL is merely a query language that accepts user input, if your API is insecure, malicious code can be injected into it, making your database, file system, network, and even OS vulnerable.
- GraphQL bombs: These were found in August 2022 and have an impact on APIs that use GraphQL file uploads. This is a DOS (Denial of Service) attack that involves flooding the GraphQL endpoint with HTTP requests.
- Misconfigured HTTP headers: Although it might seem insignificant, I assure you that it can cause much more harm than you might realize. It can be a gateway for attacks like CSRF (Cross-Site Request Forgery), MIME sniffing, Man in the Middle attack, and many more if it is not configured correctly.
- Rate limiting is misconfigured or not configured: Rate limiting simply restricts how many requests a client can make in a given amount of time. And if that isn’t configured, a DOS threat could result!
Scary, huh? Doesn’t it?
GraphQL vulnerabilities can be found, fixed, and your server can be secured using some of the best tools I’ll share with you right now. The tools we’ll talk about are listed here in brief.
1. Escape GraphQL Security
With its GeaphQL security checker, Escape continues to design its products with developers in mind.
Since you are one of the few security service providers, you can be sure that the brand-new vulnerability will be quickly scanned.
There is however more to it:
- It takes about 60 seconds to start the first scan!
- Escape’s database has been kept up-to-date on vulnerabilities.
- Shows real risks rather than showing issues that might be a risk.
- Integration with your favorite developer tools.
Therefore, Escape can be your next stop if you’re looking for a quick and simple way to check GraphQL vulnerability.
2. Inviciti GraphQL Scanner
Inviciti, formerly known as Netsparker, is one of the most reputable and well-known brands among scanning APIs.
However, a customer wants to know how many different kinds of attacks it can handle, so here is a list of serious threats and vulnerabilities that this product can scan for:
- Blind command injection
- Blind SQL injection
- Command injection
- Remote code execution
- Server-side Request Forgery
A strong defense against contemporary assaults.
