How Do Node Js Developers Fix a High-Risk Vulnerability That Could Allow Remote Domain Hijacking?
Developed by Ryan Dahl in 2009, Node Js is a platform that is based on Chrome's JavaScript runtime environment to build fast and scalable network applications easily. In addition, it uses an event-based non-blocking model, which makes it light-weighted, efficient, and perfect for data-intensive real-time applications that run on distributed devices. The latest version of Node.js is currently v0.10.36.
Since its launch in 2009, Node Js has grown significantly due to its various essential applications. Little wonder every Node Js web development company is always looking to hire Node Js developers to add to their workforce. Unfortunately, like any other programming language or framework, Node.js is susceptible to all kinds of web application exposures. While it is true that Node Js is built with top-notch security features, some third-party applications may require the addition of more security features to ensure the optimal protection of your web apps.
Why Do Node.js Projects Have Security Issues?
Open-source applications derive licensing and security risks from their open-source elements. Additionally, security detection tools such as static and dynamic code evaluation cannot effectively identify open-source exposures. To detect open-source items in Node.js, you need to evaluate the NPM index files that explain dependencies. However, these index files do not have reused open-source items. Sometimes the open-source community reuses open source projects to reduce time to market and accelerate development. Accordingly, commercial and open source developers can add snippets, functions, and techniques to it. Additionally, a Node.js development company incorporates license terms other than the basic Node.js license in its web development projects.
Top Node.js Vulnerability Risks and How to Fix Them
If Security issues related to Node.js can expose you to vulnerabilities like the man in the middle, code injection, and constant advanced threats then here is a list of Node.js security risks that can cause these vulnerabilities and the possible solution practices that Node Js development company can use to handle them:
1. Restrict XSS Attacks by Validating User Inputs
XSS or cross-site Scripting allows hackers to inject vulnerable client-side scripts into website pages viewed by different users. Vulnerable client-side scripts can cause data breaches. In addition, the hacker can use JavaScript code. The reason for this is not the validation of user input. Whatever users type in the search box will be returned to them in the same old form if it is not found in the database. Therefore, if a hacker enters JS code instead of the product name in the search bar, they can execute a similar JS code.
Solution
The user input can be validated. Several techniques could be employed to avoid getting XSS attacks in Node.js. These methods are used for output encoding, and they include the Jade engine with built-in encoding frameworks. Also, you can opt for XSSfilters or Validatorjs for this.
2. Abstain from Data Leaks
Always trust what you get from the front end and what you pass to it. For example, you can easily send all the information of a specific item to the frontend and only filter what needs to be displayed there. However, it is pretty simple for a hacker to find the hidden data sent from the backend.
Solution
Submit only the information you need. For example, if you only ask for first and last names, retrieve them from the database. You may need to do a little more work but it's worth it.
3. Utilize Security Linters
You can scan vulnerability automatically. Besides, you can catch basic security exposures even while writing the code.
Solution
You can utilize linter plugins like eslint-plugin-security. It is a form of security linter that notifies you of the use of unsafe code practices.
4. Implement Access Control on Each Request
This is usually associated with how properly examined an app has been regarding user permissions to various URLs. Thereby, if you want to have limited areas on the app, such as admin dashboard, for instance, and regular users with no appropriate role can access it by any means, then you have access exposure.
Solution
The best way to eliminate this susceptibility is by manually testing app modules that need special user permissions. Middlewares and access control rules are best executed on the server side as they reduce the chances of manipulating access permissions from the client-side by JWT (JSON Web Token) authorization tokens or cookies. The Log access controlling and API rate restricting must be set up. This is how admins get alert when essential steps are taken to reduce the attack and repeated failures.
5. Secure Deserialization
Unsafe Deserialization is a vulnerability that includes Deserialization and enforcement of faulty objects through remote code implementation or API calls. This type of attack is known as a Cross-site Request Forgery (CSRF) attack. This attack forces end-users to take unwanted actions on valid web applications. CSRF attack objects are changes in application state requests because the hacker cannot see the reaction of the spoofed request. Attackers can apply tricks to users through unusual actions using social engineering methods, such as sending links via email or chat. CSRF can force status change requests, such as transforming email credentials and then transferring funds. CSRF can compromise the entire web application for administrator users.
Solution
To reduce such hacks or attacks, CSRF must be prevented. You can do this by using the anti-counterfeiting tokens in Node.
6. Execute HTTP Response Headers
Express is one of the most widely used web application frameworks for Node.js. However, the downside to the use of Express is the absence of adequate security features. Therefore, older versions of Express may present security risks.
Solution
You should use maintained and updated versions to ensure application security. You can prevent many less common attacks by adding additional security-related HTTP headers to your application. Common frameworks like CORS can improve the safety of your API, but consider using modules like Helmet, which adds more headers to protect your application. For example, a headset can help protect Express and Node.js apps. This is a set of middleware functions that run 11 different header-based security systems for you with a single line of code. Integrate prevention of cross-site scripting attacks, mid-level attacks, and administration of secure server connections.
7. Establish Logging and Monitoring
Logging and tracking are also associated with Node.js security. After all, your goal is to secure the mechanisms from the start, but an ongoing process that requires frequent logging in and monitoring is necessary.
Solution
Some hackers want to make your app unavailable, which can be discovered without registration. But some hackers want to stay unidentified longer. In this case, monitoring logs and metrics will help you find the wrong problem. However, you cannot get enough data to determine if you are receiving weird requests from your app, a hacker, or a third-party API with just basic logging. There are different tools, many of which are communicating and combined, that offer distinct layers to strengthen the security of your system, depending on the data. The data is needed to assess and identify the exposures and potential invasions of your application. You can run many routines that are implemented based on predefined system behavior. Logging and monitoring explain everything that happens in an application. Therefore, the surveillance functions as its voice which will come to you if something vulnerable is recognized.
8. Execute Strong & Complete Authentication
Another common vulnerability is an incomplete, weak, or faulty authentication system. This probably happens because many developers think they are safe After all, they have it. But as, in reality, unstable or weak authentication is easy to circumvent.
Solution
A primary solution is to use current authentication solutions such as OAuth, Firebase Auth, or Okta. However, if you want to choose Node.js authentication solutions, keep a few things in mind. For instance, when creating passwords, never use the built-in cryptographic library Node.js; use Scrypt or Bcrypt instead. Also, be sure to limit failed login attempts and never tell users if their password or username is incorrect. In addition, appropriate session management policies are required. Make sure you are performing 2FA authentication. If done correctly, it can dramatically increase the security of your application. You can do these using modules like Speakeasy or node2fa.
9. Regularly Scan Apps Automatically for Vulnerability
The Node.js ecosystem includes several libraries and modules to install. Many of them can generally be used in your projects. However, this presents a security risk. You can't be entirely sure it's safe when using code written by someone else.
Solution
To resolve this issue, you should run an automatic vulnerability scan periodically to help you discover the dependencies that have the same security threats. Additionally, When you can get opt for NPM scanning for essential monitoring, but consider using tools like Retire.js, WhiteSource Renovate, OWASP DependencyCheck, OSS INDEX, Acutinex, and NODEJSSCAN.
10. Make Fluid Build Pipelines for Security Patches
Poorly configured security vulnerabilities occur when web servers or applications are unprotected or protected by weak security standards. Now Due to this vulnerability, different parts of the application stack (application containers, databases, servers, etc.) become prone to vulnerable exploits. Additionally, weak build pipelines are an essential entry point for misconfigured security type attacks, as staging or staging area credentials are sometimes used to build. This leaves the application exposed as development or development zone configurations to achieve lax security standards.
Solution
It is recommended that each environment (development, staging, and production) remain the same at different levels of identification and access. Using default package settings and user account passwords can cause further security threats in most Node Js applications. This is because hackers can easily attack login forms that have weak credentials. On the other hand, the default package settings leave some vulnerabilities for malicious hackers.
Conclusion
