This can be done remotely and without authentication, allowing the attacker to access and download arbitrary files from the system, potentially compromising sensitive data and threatening the integrity of the system.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-867340703\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>The following demonstrates a conceptual HTTP request exploiting this vulnerability:<\/p>\n<pre><code class=\"\" data-line=\"\">GET \/path\/to\/file\/..\/..\/etc\/passwd HTTP\/1.1\nHost: vulnerable.website.com<\/code><\/pre>\n<p>In this example, an attacker is attempting to download the &#8216;\/etc\/passwd&#8217; file, a sensitive file in UNIX-based systems, via Path Traversal.
