Attention Google Chrome Users: A Critical Zero-Day Vulnerability (CVE-2023-2033) Has Been Exploited - Take Action Now!

On Friday 14th April 2023, Google released an emergency update to fix a zero-day vulnerability that was actively exploited in the Chrome web browser. This is the first zero-day bug to be fixed this year.

The vulnerability, known as CVE-2023-2033, is a high-severity type confusion problem in the V8 JavaScript engine, which is a Google-developed open-source engine that compiles JavaScript code to native machine code for faster performance. It powers many web browsers like Chrome, Edge, and Opera and also provides an API for embedding JavaScript in other applications. It was reported by Clement Lecigne from Google's Threat Analysis Group (TAG) on April 11, 2023.

According to the National Vulnerability Database, this bug has the potential to enable a remote attacker to carry out heap corruption through a specially crafted HTML page. Google has acknowledged that an exploit for CVE-2023-2033 is already in the wild.

Although Google has not disclosed additional technical specifics or indicators of compromise (IoCs) to prevent further exploitation by threat actors, a patch for this vulnerability is now available on Chrome 112.0.5615.121 for Windows, Mac, and Linux. It will be distributed through the automatic patching mechanism of the software over the next few days or weeks.

It's worth noting that similarities have been found between CVE-2023-2033 and four other type confusion vulnerabilities, namely CVE-2022-1096, CVE-2022-1364, CVE-2022-3723, and CVE-2022-4262, which were actively exploited and fixed by Google in 2022.
