Chromium V8 Engine 远程代码执行漏洞

漏洞信息

漏洞名称： Chromium V8 Engine 远程代码执行漏洞

漏洞编号：

  • CVE： CVE-2025-1002

漏洞类型： 命令执行

漏洞等级： 严重

漏洞描述： 受影响产品: Chromium V8引擎是Google Chrome浏览器、Microsoft Edge浏览器以及Node.js等软件中使用的JavaScript引擎，广泛应用于现代Web浏览和服务器端JavaScript执行。由于其高性能和广泛的应用，V8引擎的安全问题影响范围极广。

漏洞解释: 该漏洞是一个类型混淆漏洞，存在于V8 JavaScript引擎的类型系统中。在JIT编译过程中，由于对对象类型转换的不当处理，导致类型混淆。攻击者可以通过精心构造的JavaScript代码，利用TurboFan优化编译器在处理特定对象时的类型混淆问题，实现越界内存访问，进而获得任意读写原语，最终构建ROP链绕过安全缓解措施并执行任意代码。

影响分析: 此漏洞允许攻击者在受害者访问恶意网站时，通过驱动下载等方式实现远程代码执行，完全控制受影响的系统。由于攻击需要用户交互（如访问恶意网站），但一旦触发，攻击者可实现浏览器沙箱逃逸，进一步控制系统。该漏洞的CVSS评分为9.6（严重），表明其潜在危害极大，可能导致数据泄露、服务中断等严重后果。

来源概述

Chromium V8 Engine RCE Exploit - CVE-2025-1002

Overview

This exploit targets a critical type confusion vulnerability in the V8 JavaScript engine used by Chromium-based browsers, allowing remote code execution through malicious JavaScript.

Vulnerability Details

CVE ID: CVE-2025-1002
CVSS Score: 9.6 (Critical)
Affected Software: Chrome 110-115, Edge 110-115, Node.js 18-20
Attack Vector: Network (Drive-by download)
User Interaction: Required (Visit malicious website)

Technical Description

The vulnerability exists in the V8 JavaScript engine’s type system where improper handling of object type transitions during JIT compilation leads to type confusion. When the optimizing compiler (TurboFan) processes specially crafted JavaScript code, it incorrectly assumes object types, leading to out-of-bounds memory access.

The exploit works by:

  1. Creating objects with specific properties that trigger optimization
  2. Causing type confusion during the compilation process
  3. Gaining arbitrary read/write primitives through corrupted object headers
  4. Building a ROP chain to bypass security mitigations
  5. Executing shellcode to escape the browser sandbox

Installation

1
pip install git+https://github.com/susancodes55/chromium-zero-day-rce-exploit.git

Usage

1
browser-exploit

The tool provides three modes:

  1. Generate JavaScript payload - Creates the exploit code
  2. Launch full exploitation demo - Simulates complete attack chain
  3. Interactive shell mode - Direct post-exploitation interface

$ browser-exploit
Select exploitation mode:

2. Launch full exploitation demo
3. Interactive shell mode

Enter choice (1-3): 2

[+] Generating JavaScript payload...
    // V8 Engine Type Confusion Exploit
    const buf = new ArrayBuffer(0x1000);
    const view = new DataView(buf);
    ...
[+] Payload generated successfully!

Attack Vectors

  • Drive-by Downloads: Hosting malicious JavaScript on compromised websites
  • Malicious Advertisements: Injecting exploit code into ad networks
  • Phishing Campaigns: Tricking users into visiting attacker-controlled sites
  • Watering Hole Attacks: Compromising frequently visited websites

Detection

  • Monitor for unusual JavaScript execution patterns
  • Check for heap corruption indicators
  • Look for unexpected process spawning from browser
  • Analyze network traffic for exploit kit signatures

Mitigation

  • Update Chrome/Edge to version 116 or later
  • Enable strict site isolation
  • Use browser exploit mitigation features
  • Deploy Content Security Policy (CSP) headers
  • Regular security awareness training for users
