Attack-Flow Graph

Executive Summary

This vulnerability involves incorrect authorization in FontAccess within Google Chrome versions before 155.0.8059.39. A remote attacker who already compromised the renderer process could exploit this to bypass system access restrictions using a specially crafted HTML page.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 155.0.8059.39. Detection involves checking the installed Chrome version. On Windows, run: wmic product where name='Google Chrome' get version. On Linux, check the version via the package manager or run: google-chrome --version. If the version is below 155.0.8059.39, the system is vulnerable.

Impact Analysis

If you use an affected Chrome version, an attacker who gains control of the renderer process could potentially access restricted system resources or perform unauthorized actions through a malicious webpage.

Compliance Impact

This vulnerability allows unauthorized access via a compromised renderer process, which could lead to data exposure or manipulation. Such breaches may violate GDPR's data protection requirements or HIPAA's safeguards for protected health information if exploited.

Mitigation Strategies
