Attack-Flow Graph

Executive Summary

This vulnerability is a sandbox escape issue in Google Chrome on Mac. It occurs due to an inappropriate implementation in the MHTML feature, allowing a remote attacker who has already compromised the renderer process to escape the sandbox restrictions via a specially crafted HTML page.

Detection Guidance

This vulnerability is specific to Google Chrome on Mac prior to version 151.0.7922.72. Detection involves checking the installed Chrome version. On Mac, run 'google-chrome --version' in Terminal. If the version is below 151.0.7922.72, the system is vulnerable.

Impact Analysis

If you use Google Chrome on Mac prior to version 151.0.7922.72, an attacker could exploit this flaw to bypass security restrictions. This might allow them to access sensitive data, execute malicious code outside the browser's sandbox, or perform actions with higher system privileges than intended.

Compliance Impact

This vulnerability does not directly impact compliance with GDPR, HIPAA, or similar standards as it involves a sandbox escape in Google Chrome's MHTML implementation on Mac. Compliance implications would depend on specific use cases and data handling practices rather than this technical vulnerability.

Mitigation Strategies

Update Google Chrome on Mac to version 151.0.7922.72 or later to address the sandbox escape vulnerability in MHTML.
