5 ReactJS Security Vulnerabilities – How to Fix Them

When we talk about a popular front-end library for developing a web app, the name React comes in the first place. ReactJS is one of the best front-end development frameworks for building SPAs and MPAs for a diverse range of enterprises.

It is unquestionably the most acquired framework for developing an interactive, engaging, and intuitive front-end of the application. There is a lot to talk about ReactJS services and all those profit-oriented things that can help to create a compelling web app for your enterprises.

But here, the major concern is security and possible vulnerabilities that one may face while developing a ReactJS web application. No wonder, even the ReactJS framework is not pruned against a few security issues. And, you have to fix the same after rectifying it as early as possible.

So, for your assistance, we bring forth some of the minor to major vulnerabilities that can seriously break your application. And, it will impact your whole enterprise solutions.

Without any further adieu, let’s check out the security issues of the ReactJS framework.

Avoid these 5 ReactJS Security Vulnerabilities

5 ReactJS Security Vulnerabilities – How to Fix Them

Cross-Site Scripting- A Malicious Client-Side Scripts

Cross-Site Scripting is one of the most common security issues with ReactJS web apps. It means, malicious client-side scripts entering the web app and messing up with the controls, connect the computer with a camera or steal the sessions or cookies.

In general, there are two types of cross-site scripting to encounter

  • Reflected Cross-Site Scripting: This security attack happens when the attacker uses a malicious link with misleading information. This false information can go into the page of the web browser read as app code. For example, an attacker fills up the form on your web app with inappropriate information and submit the same.
  • Stored Cross-Site Scripting: In this attack, the malicious entity tries to upload something on your web application and gets it rendered. The most common examples are of adding unwanted images or comments.

How to Prevent?

  • Disable the markups with code running instructions.
  • Use {}for default data binding.
  • Employ Web Application Firewall.
  • Use HTML library capable of parsing HTML formatted-text.
  • Use URL parsing and conducting Whitelist/Blacklist validation.

SQL Injection- Hackers Get into your Database

SQL injection is a serious security threat to your ReactJS web application. It is a trick used by hackers to inject your database with random SQL code. After doing this, they can edit, receive, or delete data without needing user permissions.

In such an attack, hackers can pull off SQLi by creating new credentials or faking out that can cause serious damage to your web app. Moreover, they can modify the data accordingly or can even destroy the same.

How to Prevent?

  • Use the filter for user inputs with strict whitelists.
  • Assign the right database roles to different accounts.
  • Follow the principle of least privilege with all the accounts.

Compromised Authentication- Security Exploitation

Another possible security threat to your ReactJS web app is when hackers break the authentication and bring vulnerabilities. Well, if that happens, then hackers can do a lot of mess with the account information, passwords, sessions tokens, etc.

There could be several reasons for having such a vulnerable authentication implementation that is as follows:

  • Predictable user credentials.
  • Unprotected user authentication credentials.
  • The session ID is exposed in the URL.
  • Session ID not rotated after login or vulnerable to session fixation attacks.
  • Session ID, passwords, and other credentials sent over unencrypted connections.

How to Prevent?

  • Set up multi-factor authentication.
  • Maintain password checks in terms of strength or weakness.
  • Make the best use of NIST 800-63B guidelines for password length and complexity.
  • Use the same messages for all authentication.

Zip Slip- File Extraction

Zip Slip is more like a security loophole that happens either on the part of web developers or users. In general, users submit the zip files in order to reduce the size of the files.

Sometimes, few files are left outside the designated folder and hackers gain access to the same. They can overwrite them to involve files remotely or make the system call them. Whatever be the move, it poses a serious threat to the security of the web app.

How to Prevent?

  • Make sure to name the files with standard terms.
  • Do not use special characters in the name of files.
  • Compare and match the names with regular, standard expressions.
  • Rename all the uploaded files in the zip.

XML External Emtities- Confidential Data Attack

Such attacks are also termed as some kind of injection in your web app. XML parses that have become outdated are vulnerable to your ReactJS web application that could lead to DoS attacks. In such kinds of serious attacks, the hackers can collect confidential information from the server and misuse it.

How to Prevent?

  • Use complex JSON formats to avoid serialization.
  • Use SAST tools to identify the mischievous XXE in your code.
  • Keep upgrading the XML processors periodically.

End Note

It is important to identify and fix simple to complex security issues attacked with your ReactJS web application. Do not let hackers do some mischief to your app, sensitive information, user data, and more. Keep an eye on the above-mentioned vulnerabilities to stay alarmed.
