As many users trust the Microsoft Edge browser for its speedy performance and security features, any vulnerability relating to this popular browser must be dealt with as quickly as possible. In this post, we'll dive into the specifics of CVE-2024-30058, provide code snippets for the exploit, and provide links to the original references.

Exploit Details

The vulnerability exists in the Chromium-based version of the Microsoft Edge browser, where a malicious attacker can potentially manipulate the browser's rendering to present deceptive or malicious content. This exploit can be used to manipulate users into clicking on malicious links, downloading malware-infected files, or sharing sensitive information unwittingly. The Chromium-based version of the Microsoft Edge browser is used on operating systems like Windows 10, Windows 8/8.1, Windows 7, Windows Server 2016, Windows Server 2019, and Windows Server, among others.

Here's a code snippet of a possible exploit

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>CVE-2024-30058 Exploit</title>
</head>
<body>
<p>Click this link to visit <a href="https://www.example.com"; target="_blank">Example.com</a>.</p>
<script>
var link = document.querySelector("a");
link.onclick = function() {
  link.innerHTML = "https://www.evil-domain.com";;
};
</script>
</body>
</html>

The above code snippet creates a simple web page where the displayed link seems to lead to example.com. However, once the user clicks on the example.com link, it changes the visible link text to evil-domain.com, which indicates a successful attempt at exploiting the vulnerability.

As of the time of this writing, Microsoft has not released a security patch for the CVE-2024-30058 vulnerability.
