A reflected Cross-Site Scripting (XSS) vulnerability exists in password.php, allowing attackers to execute arbitrary JavaScript in a user's browser, which can lead to session theft or other malicious actions. Specifically, the application directly echoes unsanitized input from the 'asdf' GET parameter on lines 23-24 (echo $_GET['asdf'];) into the HTTP response. An attacker could craft a malicious URL like
/password.php?asdf=<script>...</script>to trigger the vulnerability.
