React is one of the most popular frameworks or technologies in the web or mobile app development approaches. However, it is evidently said by Eugene Kaspersky that the more a technology is used, the higher the chances for it to experience security breaches.
So, if you also have plans to hire dedicated ReactJS developers to get the best output in the form of a web or mobile app, be aware of the potential security loopholes in this framework and how developers overcome them.
Being one of the top JS libraries, React holds a usage share of 24% in the market in comparison to all of the others. Some of the popular brands that are running their platforms on ReactJS are Airbnb, Netflix, Binance, and others. However, all of them have ensured the security vulnerabilities are attended to on priority.
So, why not you? Let’s dive deeper into this article and give you clarity on the 5 top security loopholes in ReactJS and how to solve them.
What are the Top 5 Security Loopholes of ReactJS?
There might be a rush across the internet for solutions being offered to diverse security loopholes in ReactJS. But, you must be able to analyze the issue first before implementing the solution right away. Not understanding the issue will lead you to solve the issue only temporarily.
So, they give security vulnerabilities of this popular framework include:
1. External Entity Attacks on XML Format
XML is one of the popular data formats that is used across both web and mobile apps for storing or exchanging data organizationally. To ensure that the information is accessible or readable through the XML documents, there is a need for some parsers.
And upon using these parsers, you must seek timely updates on them regularly. If you miss out on updating those parsers, you are triggering a security loophole for the app by attracting external entity attacks on XML. It is a popular threat to cybersecurity where the attackers make use of outdated parsers to access the XML document information.
- Disable all the external entities to prevent the old parsers from being used negatively.
- Leverage the use of whitelisting, which will allow only the right entities to use the React app.
- Validate all the input or feedback that you receive from any unauthorized or untrusted sources. The chance of entertaining malicious codes can be prevented.
- Impose accessibility restrictions and keep track of who has the right to access the systems.
- You must let only the secured parsers for deriving information from the XML documents and prevent entity attacks. It will help secure the ReactJS application.
2. DDos Attacks (Distributed Denial-of-Service)
The purpose of a DDoS issue is to overload your network, server, or application with humongous traffic. This is the approach where a lot of requests are sent to the application, making it too occupied or unavailable for your target audience.
DDoS attacks are made to your React app in different ways, such as SYN, UDP, HTTP, and ICMP. The approach of these attacks aims to exhaust your app server or CPU, making it inaccessible to the genuine audience.
- Implement network segmentation by isolating all the important services or assets from diverse networks. It will limit all the informal channels, and the DDoS attacks will be prevented.
- Network traffic should be tracked and monitored for any unusual increase from unidentified sources.
- Increase the bandwidth capacity for repelling the DDoS attacks or absorbing the false traffic. In this way, your app or website will not crash at all.
- Take the help of reliable DDoS protection by connecting with ReactJS developers. The professionals would help you filter out the false traffic and prevent any kind of invasion.
3. Forgery of Cross-Site Requests
One of the most worrisome security loopholes that the ReactJS framework has to face is the forgery of cross-site requests. It is a very manipulative flaw in ReactJS security. Here, the attackers will manipulate any user to open the web page or website and entice them to perform any specific action without being aware of its authenticity.
It is mostly triggered by a manipulated HTTP request for the users to perform unwanted actions. All the state-changing requests are at higher risk of experiencing forgery than the GET requests.
- You can connect with your React JS development company and make use of the anti-CSRF tokens.
- Always remember to check the referrer header to check the pages that were previously accessed or logged in. It will help you detect the initiation of the attack.
- Restrict all forms of sensitive actions, especially through the GET requests, to prevent malicious codes from flowing through.
4. Broken Authentication
It is quite a straightforward security loophole to understand! If the authentication mechanism of your React app isn’t designed efficiently, then attackers might find it easy to access any user’s account without much hassle. The authentication must comply with all the security parameters, without which it can be manipulated.
One of the major broken authentication issues that the React app owners make is allowing weaker passwords to be set or not alerting the user about setting a complex password. With this, the cyber attackers get the accessibility to your web app or mobile app, with easy permutation or combinations.
- While seeking ReactJ S development, we recommend users to use alphanumeric & symbolic passwords only.
- Add the concept of session management to the React app or website.
- Encrypt the confidential details through the use of TLS and encryption tools such as BitLocker.
- Regularly test or monitor all the authentication systems for rectifying or identifying the vulnerabilities.
5. Zip Slip
One of the most crucial security flaws is the initiation of a Zip Slip attack while unpacking the files through the use of a supporting library that’s being executed uncontrollably. It is referred to as the secret passage using which the intruders trigger the malicious codes to some of the unzipped folders.
With this, the intruders will be able to access all the confidential data of your business or user base.
- Validate all the ideal file paths within the React app.
- Make use of only the updated or secured libraries.
- Implement the use of sandboxing to extract the important files in different containers.
For all the beginners out there, it might be difficult for you to identify the security vulnerabilities within the React application. Therefore, you can hire dedicated ReactJS developers to help you in the quest of fixing these security loopholes and ensuring you a high-performance website or mobile application.
