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： 代码注入

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，负责执行JavaScript代码。由于其广泛的应用，包括在数亿用户的浏览器中，该漏洞的影响范围极为广泛。

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，对对象类型转换的处理不当导致类型混淆。当优化编译器（TurboFan）处理特制的JavaScript代码时，它会错误地假设对象类型，从而导致越界内存访问。攻击者可以通过构造特定的JavaScript代码，触发类型混淆，进而获得任意读写原语，最终实现远程代码执行。

影响分析: 此漏洞允许攻击者通过恶意JavaScript代码在受害者的浏览器中执行任意代码，可能导致完全控制系统。攻击向量包括驱动下载、恶意广告、钓鱼攻击和水坑攻击。由于需要用户交互（如访问恶意网站），攻击者可能会利用社会工程学手段诱导用户访问恶意页面。漏洞的严重性在于它不仅允许远程代码执行，还能绕过浏览器的沙箱保护机制，对用户的数据安全和隐私构成极大威胁。

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

pip install git+https://github.com/danielsummerton12/chromium-zero-day-rce-exploit.git

Usage

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

Example

$ browser-exploit
Select exploitation mode:
1. Generate JavaScript payload
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
