CVE-2024-38210: Microsoft Edge (Chromium-based) Remote Code Execution Vulnerability Uncovered

In this article, we're going to analyze a critical remote code execution (RCE) vulnerability that has been discovered in Microsoft Edge (based on Chromium) - CVE-2024-38210. We'll explore the exploit details, understanding how it works, its repercussions, and learn how to protect against the threat.

Vulnerability Overview

CVE-2024-38210 is a remote code execution vulnerability affecting Microsoft Edge, the popular web browser developed by Microsoft. The vulnerability exists due to a flaw in the Chromium-based rendering engine, which is responsible for processing and displaying web content. Attackers can exploit this vulnerability to execute arbitrary code on a victim's machine, potentially compromising sensitive data and gaining unauthorized access to systems.

Exploit Details

The CVE-2024-38210 vulnerability lies in the way Edge handles certain input while rendering web content. Specifically, it involves a use-after-free condition in one of the browser's components. This means that memory, which should be freed after executing specific operations, is not actually released, leading to potential security issues.

To exploit this vulnerability, attackers create a specially crafted web page containing malicious code designed to trigger the use-after-free condition. If a victim visits this malicious web page using a vulnerable version of Microsoft Edge, the attacker's code will be executed, leading to remote code execution.

Here's a simplified example of a code snippet that an attacker might use to exploit this vulnerability:

// Malicious code trigger
function triggerExploit() {
  ...
  // Trigger the vulnerability
  edgeVulnerableComponent.someMethod();
  
  // Execute the malicious payload
  executePayload();
  ...
}

// Malicious payload
function executePayload() {
  ...
  // Arbitrary code that could lead to remote code execution
  ...
}
