New Google Chrome Vulnerability Exploits and What You Need to Know

Google is reporting on new vulnerability exploits you'll want to be aware of to help secure your site. Here are essential tips to help you.
One of the biggest challenges regarding website security is staying on top of evolving threats and trends. Google is aware of new vulnerability exploits in the wild you'll want to be mindful of to help secure your site. In 2022 Google discovered multiple vulnerabilities in the V8 JavaScript engine, which can lead to malware infecting your website visitors.

Following is a list of the discovered vulnerabilities:

  • CVE-2022-1096 - Type confusion in V8 in Google Chrome prior to 99.0.4844.84 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.
  • CVE-2022-1364 - Type confusion in V8 Turbofan in Google Chrome prior to 100.0.4896.127 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.
  • CVE-2022-3723 - Type confusion in V8 in Google Chrome prior to 107.0.5304.87 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)
  • CVE-2022-4262 - Type confusion in V8 in Google Chrome prior to 108.0.5359.94 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)
If left unchecked, these vulnerabilities can severely damage your website and the devices of anyone visiting it. If those people are your customers, it could lead to problems for them and headaches for your business in the long run.

Like any digital threat, there's nothing about this vulnerability you can't stop with education. But you need more than what it is - you'll also need to know the next step to prevent hackers from exploiting it.

This post will explain more about these vulnerability exploits, how a hacker might take advantage of them, as well as preventative measures you can take to combat hacking and protect yourself.
What is Type confusion vulnerability?
In simplified form, a bug in the V8 JavaScript engine used by Chrome occurred due to incorrect reference and management of the allocated memory used to store JavaScript objects. This leads to memory corruption and further to malware infection.

Following is an example of obfuscated JavaScript exploit which could be used to benefit from such vulnerabilities:
Such JavaScript code could be injected into any HTML page and will lead to malware infection of any visited devices using an outdated version of Chrome.

Like other vulnerability exploits, this can expose you to various risks if a hacker were to take advantage.

A hacker or malicious actor can weaponize this kind of vulnerability for many nefarious reasons: to perform out-of-bounds memory access, execute a malware lode, or execute arbitrary code intended to crash or reinfect a website visitor's device.

After this unique code has infected your website, execution of the code on your website visitor's device will crash Google Chrome, followed by a complete malware infection.

This kind of behavior on behalf of your website will get your website blacklisted by significant vendors. That leads to a loss of commercial traffic flowing into your site. This can lead to a loss of business or reputation, negatively impacting your ability to operate successfully.

The security vulnerability found in V8 JavaScript engine affects Chrome users, but it can also be used in other browsers and platforms. It's essential to know about this vulnerability so you can protect yourself from malware infections that travel to the devices of your site visitors.
Why This Vulnerability is Such a Major Threat
So why worry about this vulnerability? As mentioned above, Google has issued an update for this bug. But what does this mean for you? As we all know, Google constantly scans its browsers, looking for issues like these.

If you're up to date, you're covered. If you have an old version of Chrome installed, however, you may be vulnerable even though there hasn't been any malicious code released, as hackers have yet to use this exploit. You also may become susceptible to other undiscovered vulnerabilities.

This underlines the importance of frequent updates to the applications you use. And though it may not have been exploited yet, a serious threat is associated with this vulnerability.

This vulnerability highlights the need for a modern, well-equipped security posture to protect your website. Without a comprehensive plan to address vulnerabilities, you'll find yourself reacting to an attack after it occurs. This puts you on the defensive, scrambling to mitigate the impact when having a proactive stance could have done so much more to prevent the attack from occurring.

The question then becomes: what can you do to halt a hacker from taking advantage of this vulnerability from harming your site?
How to Prevent This Security Vulnerability
Vulnerabilities like these can threaten your site with untold damage. The best way to stay ahead of the curve is to have the right security tools to address these issues.

The key to getting the most out of your WAF is understanding the solution and how it can help your site. Implementing a WAF (web application firewall) can prevent malware infection. Think of it like a security system for your site, keeping tabs on malicious actors and other potential threats to your site's safety.

To truly derive the biggest ROI from a WAF, you'll need to partner with a provider or service that can implement this for you. Depending on your chosen provider, this can involve complex configurations to ensure optimal protection. You can attempt this on your own, but it will take you away from regular business operations to focus on your site's security - an area you may likely need more knowledge of.

With the right solution, however, you won't have to worry about that.
