This issue was identified and assigned CVE-2024-43472 as a globally unique identifier, helping security professionals track, rank, and remediate the vulnerability. This blog post will outline the details of CVE-2024-43472, including example code snippets, references, and a thorough discussion of how the exploit could be used by a malicious actor.

CVE-2024-43472 Overview

Discovered recently by security researchers, the Chromium-based Microsoft Edge has been found to have a vulnerability classified as an "Elevation of Privilege" issue. In simple terms, this means that it grants a user on the target system elevated privileges, potentially allowing them to access resources or perform actions that would otherwise be forbidden.

The actual vulnerability lies in Microsoft Edge's handling of specific browser components, which, when exploited, could allow an attacker to execute arbitrary code. For a detailed explanation of the Chromium-based Microsoft Edge security issue, consult this Microsoft Security Advisory: MSA-2024-43472.

Below is a simplified code snippet representing the exploit for this vulnerability

// Import relevant classes
import EdgeBrowser from 'edge-browser';
import Exploit from 'exploit';

// Instantiate the EdgeBrowser class
const edge = new EdgeBrowser();

// Specify the malicious payload
const payload = YOUR_MALICIOUS_CODE_HERE;

// Create the Exploit class with the payload
const exploit = new Exploit(payload);

// Execute the exploit
edge.executeExploit(exploit);
