Two new zero-day exploits that affect the Chromium browser core were reported on April 14th. And since both Chrome and Microsoft Edge are based on it, Google advised to update the browsers. The vulnerabilities CVE-2023-2033 and CVE-2023-2136 can lead to remote code execution and have already been fixed.

But that doesn't mean that's the end of the problem. If the automatic updates on your organization's browsers aren't enabled, you need to find outdated versions and patch them as soon as possible to avoid potential threats.

Keep reading to learn more about the exploits and how to spot software that needs updates on your company network with InvGate Insight!

About CVE-2023-2033

CVE-2023-2033 corresponds to a type confusion in Chromium's open-source JavaScript engine V8 in Google Chrome browsers that haven't been updated to versions 112.0.5615.121 or later. If exploited, an attacker could "potentially exploit heap corruption via a crafted HTML page."

According to the NIST's National Vulnerability Database (NVD), the Chromium security severity is high.

Since this is a remote code execution, the vulnerability can be exploited from outside your company network. If we take into account that Google confirmed this exploit has been actively exploited in the wild, patching outdated Chrome browsers is urgent.

About CVE-2023-2136

On the other hand, CVE-2023-2136 corresponds to an integer overflow in Skia in Google Chrome browsers that haven't been updated to versions 112.0.5615.137 or higher. According to the official statement, it allows a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. 

As with the other vulnerability, this one has been labeled as high severity and exploited in the wild.

And since Microsoft Edge browsers are also Chromium-based, you should see that they are updated to versions 112.0.1722.58 or later.
