Unsanitized user input from the 'asdf' parameter is echoed directly into the HTTP response in
admin.phpon line 16, which allows an attacker to inject arbitrary JavaScript code into the page. This reflected cross-site scripting (XSS) vulnerability can lead to session hijacking, defacement, or redirection of users to malicious sites. By crafting a malicious URL, an attacker can execute arbitrary JavaScript in the victim's browser when they visit the link.
