Attack-Flow Graph

Executive Summary

This is a race condition vulnerability in Google Chrome's Extensions feature. A race condition occurs when the system's behavior depends on the sequence or timing of uncontrollable events. In this case, the flaw allowed a remote attacker to bypass system access restrictions by exploiting timing issues in Chrome's extension handling prior to version 152.0.7977.65.

Detection Guidance

This vulnerability involves a race condition in Google Chrome's Extensions functionality. Detection requires checking the installed Chrome version and reviewing installed extensions for potential malicious activity. Use chrome://version/ to check the version and chrome://extensions/ to inspect installed extensions. Ensure Chrome is updated to version 152.0.7977.65 or later to mitigate the issue.

Impact Analysis

The impact is limited due to the low severity rating. An attacker could potentially bypass security restrictions to gain unauthorized access to system resources or sensitive data through a crafted Chrome extension. However, this requires the victim to install a malicious extension, making user interaction a necessary factor for exploitation.

Compliance Impact

The vulnerability involves a race condition in Google Chrome's Extensions that could allow a remote attacker to bypass system access restrictions via a crafted extension. This could potentially lead to unauthorized data access or modifications, which may impact compliance with standards like GDPR (data protection) or HIPAA (healthcare data privacy) if sensitive data is exposed or altered.

Mitigation Strategies

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