Attack-Flow Graph

Executive Summary

This vulnerability involves incorrect authorization in Google Chrome before version 152.0.7977.65. A remote attacker who already compromised the renderer process could bypass web origin policy by using a specially crafted HTML page.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 152.0.7977.65. Detection involves checking the installed Chrome version. On Windows, run 'chrome://settings/help' in Chrome to check for updates. On Linux, use 'google-chrome --version' or check your package manager (e.g., 'apt list --installed | grep google-chrome'). If the version is below 152.0.7977.65, the system is vulnerable.

Impact Analysis

If exploited, this flaw could allow an attacker to bypass security restrictions, potentially accessing sensitive data or performing unauthorized actions on websites you visit. This is especially risky if you use Chrome for sensitive activities like banking or work.

Compliance Impact

This vulnerability allows a remote attacker to bypass web origin policy, which could lead to unauthorized access to sensitive user data. This may impact compliance with GDPR by potentially exposing personal data without proper authorization, and with HIPAA by risking unauthorized access to protected health information if such data is processed in the affected environment.

Mitigation Strategies

Update Google Chrome to version 152.0.7977.65 or later to address the incorrect authorization issue in the renderer process.
