This reflected cross-site scripting (XSS) vulnerability in picture.php allows an attacker to execute arbitrary JavaScript code in a user's browser. The vulnerability exists because the application echoes the value of the
asdfparameter from the GET request directly into the HTML output on line 14 without proper sanitization, which causes the browser to execute any malicious script injected via the URL.
