Reflected XSS Vulnerability in comments.php via 'asdf' Parameter (Severity: MEDIUM)

This reflected XSS vulnerability allows an attacker to execute arbitrary JavaScript code in a user's browser, potentially leading to session hijacking or defacement. The vulnerability exists in comments.php at line 16, where the value of the 'asdf' parameter from the $_GET array is directly echoed into the HTML output without proper sanitization, which causes any injected script code to be executed.

Reflected XSS vulnerability in comments.php via 'asdf' parameter (Severity: MEDIUM)

This reflected cross-site scripting (XSS) vulnerability allows an attacker to execute arbitrary JavaScript code in a victim's browser, potentially leading to account compromise or data theft. The comments.php script directly echoes the asdf GET parameter on line 16 without any sanitization or escaping, which causes any provided JavaScript code to be executed when a user visits the crafted URL.
