CVE-2024-10487 - An In-Depth Guide to Out of Bounds Write Vulnerability in Google Chrome's Dawn Engine Exploitation

Poster -

Google Chrome's popular browser is known for its performance, user experience, and security. But it is not without its share of vulnerabilities. In this post, we will delve deep into a critical security vulnerability, known as CVE-2024-10487, affecting Google Chrome prior to version 130..6723.92. This vulnerability lies within Chrome's Dawn engine and enables remote attackers to perform out of bounds memory access via a specially crafted HTML page. We will cover the exploit details, provide code snippets, and offer links to original references that can help you understand and mitigate the risks associated with this vulnerability.

Details of the Vulnerability

The CVE-2024-10487 vulnerability specifically targets the Dawn rendering engine in Google Chrome (Chromium security severity: Critical). This engine is responsible for rendering WebGL and WebGPU content in the browser, and the presence of an out of bounds write flaw makes it susceptible to exploitation.

The vulnerability might lead to data corruption, crashes, or even remote code execution if exploited successfully by a malicious attacker. A remote attacker can craft an HTML page that exploits this vulnerability and potentially gain access to unauthorized information, potentially compromising the victim's security.

To better understand the vulnerability, you must know about the Dawn engine and how it interacts with the browser.

Dawn Engine

Dawn is a system-level component in Chrome responsible for rendering WebGL and WebGPU content. It plays a vital role in providing robust 3D graphics and ensuring the web pages display correctly. The out of bounds write flaw in CVE-2024-10487 was discovered in the Dawn engine, leading to potential arbitrary code execution.

Exploit Details

In order to exploit CVE-2024-10487, a malicious user needs to create a specially crafted HTML page that triggers the vulnerability in the rendering process. This may be accomplished by taking advantage of the flaw within the Dawn Engine's memory handling. Below is a sample code snippet that demonstrates this exploit:

<!DOCTYPE html>
<html>
  <head>
    <title>CVE-2024-10487 - Out of Bounds Write Exploit</title>
  </head>
  <body>
    <canvas id="targetCanvas"></canvas>
    <script>
      // Exploit code goes here...
    </script>
  </.body>
</html>

This HTML code creates an environment where the attacker can interact with WebGL or WebGPU APIs, which can be used to exploit the vulnerability by overwriting the memory boundaries associated with the engine.
