Google Chrome Zero-day Remote Code Execution Vulnerability

Rajvardhan Agarwal, a security researcher, recently tweeted about a zero-day remote code execution vulnerability creating havoc in the browser-based vulnerability trend. Hereleased a working proof-of-concept exploit for the RCE for the V8 JavaScript engine in Chromium-based browsers.

This zero-day concerns a remote code execution vulnerability in the V8 JavaScript rendering engine that powers the web browsers. The exploit needs to be chained with another flaw that can allow it to escape Chrome’s sandbox protections, meaning the –no-sandbox flag should be enabled prior to the browser’s launch.

Once the sandbox is disabled, the PoC exploits browsers to launch the Calculator app on Windows 10 devices. Below snapshot was tested on Google Chrome 89.0.4389.114.
