Overview
Google recently released a patch for a new zero-day vulnerability found in the Chromium open-source web browser project, which provides the codebase behind popular web browsers. The vulnerability is tracked as CVE-2022-3723 and according to Google, is linked to type confusion in V8 in Google Chrome prior to 107.0.5304.87. It can allow a remote attacker to potentially exploit heap corruption via a maliciously crafted HTML page. Google has disclosed that the vulnerability is currently known to be actively exploited, making this disclosure a concern for any organization or individual that leverages the Chrome browser across Android, Windows, Mac, or Linux.
Lookout Analysis
The most likely way for an attacker to exploit this vulnerability would be to send a link leading to a malcrafted webpage to their target in hopes that the target still has a vulnerable version of Chrome on their device. A successful exploit may grant a threat actor access to Chrome's capabilities without needing to root the device. Mobile device management (MDM) tools will not detect a successful exploitation. In the event of a successful exploit, the actor could have access to any capability that the browser has.
