This reflected cross-site scripting (XSS) vulnerability could allow an attacker to execute arbitrary JavaScript in a user's browser, potentially leading to session hijacking or defacement. The
install.phpscript directly outputs the value of theasdfGET parameter on lines 12-13 usingecho $_GET['asdf']without any sanitization. This allows an attacker to inject malicious scripts into the page by crafting a URL with a JavaScript payload in theasdfparameter.
