Reflected XSS Vulnerability in register.php via 'asdf' Parameter (Severity: HIGH)

Unvalidated input can lead to arbitrary code execution. The register.php script directly reflects the asdf GET parameter in the HTTP response on lines 20-21. This lack of output encoding allows an attacker to inject malicious HTML or JavaScript via a crafted URL, which can then be executed in the victim's browser, potentially leading to cookie theft or other malicious actions.

Suggested change
echo $_GET['asdf'];
echo htmlspecialchars(isset($_GET['asdf']) ? $_GET['asdf'] : '', ENT_QUOTES, 'UTF-8');

    • Score: HIGH (80.0)
    • Description: Reflected Cross-Site Scripting (XSS). The new code echoes an untrusted GET parameter directly to the HTTP response (echo $_GET['asdf'];) without any validation or output encoding, which allows an attacker to craft a URL that injects arbitrary HTML/JavaScript into the registration page. When a victim visits the crafted link, the injected script runs in the victim's origin, enabling theft of cookies, session fixation, or actions performed on behalf of the user.

    • Score: HIGH (72.0)
    • Description: High impact reflected Cross-Site Scripting (XSS). The new code unconditionally echoes the GET parameter 'asdf' (echo $_GET['asdf'];) directly into the registration page response, which causes any attacker-supplied HTML or JavaScript to be executed in a victim's browser when they visit a crafted URL. This can be exploited to steal session tokens, perform actions on behalf of the user, escalate CSRF attacks, or phish users.
