CVE-2024-10230: Google Chrome V8 RCE Vulnerability

CVE-2024-10230 Overview

CVE-2024-10230 is a type confusion vulnerability in the V8 JavaScript engine used by Google Chrome. This vulnerability exists in versions prior to 130.0.6723.69 and could allow a remote attacker to potentially exploit heap corruption through a specially crafted HTML page. The Chromium security team has classified this vulnerability as High severity.

Critical Impact
Remote attackers can exploit heap corruption via crafted HTML pages, potentially leading to arbitrary code execution in the context of the browser process.

Affected Products

Google Chrome versions prior to 130.0.6723.69

Technical Details for CVE-2024-10230

Vulnerability Analysis

This vulnerability is classified as CWE-843 (Access of Resource Using Incompatible Type, also known as Type Confusion). Type confusion vulnerabilities in V8 occur when the JavaScript engine incorrectly assumes an object's type during runtime execution. When V8's optimizing compiler makes incorrect assumptions about the type of a JavaScript object, it can generate code that accesses memory using the wrong type layout, leading to heap corruption.

The network-based attack vector requires user interaction, meaning a victim must navigate to a malicious webpage containing the crafted HTML and JavaScript code. Once triggered, the vulnerability can compromise the confidentiality, integrity, and availability of the affected system.

Root Cause

The root cause lies in V8's type inference and optimization pipeline. During JavaScript execution, V8 attempts to optimize code by making assumptions about object types. When these assumptions are violated due to edge cases in type transitions or prototype chain manipulations, the engine may access memory using an incompatible type structure. This mismatch between expected and actual memory layouts results in heap corruption that can be leveraged for exploitation.

Attack Vector

The attack vector is network-based and requires user interaction. An attacker would need to:

Craft a malicious HTML page containing JavaScript that triggers the type confusion in V8
Lure a victim to visit the attacker-controlled webpage
The crafted JavaScript would exploit the type confusion to corrupt heap memory
Successful exploitation could allow arbitrary code execution within the browser's renderer process

The vulnerability manifests in V8's type handling during JavaScript execution. For detailed technical information, refer to the Chromium Issue Tracker #371565065 (access may be restricted until the majority of users have updated).

Detection Methods for CVE-2024-10230

Indicators of Compromise

Unexpected browser crashes or hangs during normal web browsing
Abnormal memory consumption by Chrome renderer processes
Browser process spawning unexpected child processes
Unusual network connections initiated by browser processes after visiting suspicious websites

Detection Strategies

Monitor for Chrome versions below 130.0.6723.69 across your organization's endpoints
Implement web filtering to block known malicious domains serving exploit code
Use endpoint detection and response (EDR) solutions to identify suspicious browser process behavior
Deploy browser isolation solutions for high-risk users accessing untrusted content

Monitoring Recommendations

Enable Chrome's built-in crash reporting and monitor for V8-related crashes
Configure SIEM rules to alert on unusual browser process activity patterns
Monitor for JavaScript execution anomalies in web proxy logs
Track Chrome version deployments across enterprise endpoints to identify outdated installations

How to Mitigate CVE-2024-10230

Immediate Actions Required

Update Google Chrome to version 130.0.6723.69 or later immediately
Enable automatic updates in Chrome to receive future security patches
Consider using browser isolation for untrusted web content until patching is complete
Review and restrict access to potentially malicious websites through web filtering

Patch Information

Google has released a security update addressing this vulnerability in Chrome version 130.0.6723.69. The fix was announced in the Google Chrome Stable Update on October 22, 2024. Organizations should prioritize deployment of this update across all endpoints.

Workarounds

Enable Site Isolation in Chrome to limit the impact of renderer compromises
Use browser extensions that block JavaScript execution on untrusted sites
Consider using alternative browsers temporarily for high-risk activities if immediate patching is not possible
Implement network-level controls to block access to known malicious domains

bash

# Verify Chrome version and update on Linux
google-chrome --version
# Update Chrome on Debian/Ubuntu
sudo apt update && sudo apt upgrade google-chrome-stable

# For enterprise deployment, use Chrome Browser Cloud Management
# or deploy via GPO on Windows environments
