Attack-Flow Graph

Executive Summary

This vulnerability is an incorrect authorization issue in Google Chrome's Media component on Windows. It allows a remote attacker who has already compromised the renderer process to bypass system access restrictions by using a specially crafted HTML page.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 152.0.7977.65 on Windows. Detection involves checking the installed Chrome version. Use the command 'chrome://settings/help' in Chrome to check for updates or run 'wmic product where name="Google Chrome" get version' in Command Prompt to verify the version.

Impact Analysis

If you use Google Chrome on Windows and visit a malicious website, an attacker who controls the site could exploit this flaw to bypass security restrictions. This might allow them to access restricted system features or data, but only if they already have control of the browser's renderer process.

Compliance Impact

This vulnerability allows a remote attacker to bypass system access restrictions via a crafted HTML page, which could lead to unauthorized data access or modification. Such unauthorized access may violate compliance requirements under GDPR (data protection) and HIPAA (health information privacy) by exposing sensitive user data without proper authorization.
