Attack-Flow Graph

Executive Summary

This vulnerability involves incorrect authorization in USB handling within Google Chrome versions before 152.0.7977.65. A remote attacker who already compromised the renderer process could exploit this through social engineering to potentially execute arbitrary code outside the sandbox by tricking a user into visiting a crafted HTML page.

Detection Guidance

This vulnerability requires checking the Chrome version installed. Run 'google-chrome --version' or check via 'chrome://settings/help' in the browser. If the version is below 152.0.7977.65, the system is vulnerable.

Impact Analysis

If you use an affected version of Chrome, an attacker could gain control of your system by exploiting this flaw. This could lead to unauthorized access, data theft, or installation of malware. The attack requires prior compromise of the renderer process, which is typically achieved via other means like phishing.

Compliance Impact

This vulnerability does not directly affect compliance with GDPR, HIPAA, or similar standards as it involves a technical flaw in authorization within Google Chrome's USB handling. Compliance impacts would depend on how the vulnerability is exploited in a specific environment.

Mitigation Strategies

Update Google Chrome to version 152.0.7977.65 or later to address the vulnerability.
