I. BACKGROUND
 
Joomla PHP Pages Component allows you to create simple PHP pages
and link them to the Joomla Menu. This allows you to easily create
a custom page without having to create a whole component. It is
similar to the PHP Module for Joomla, except that it is a full Component.

/components/com_php/php.php
 
[35] $filename = $Params-&gt;get('file', '');
[36] $path = JPATH_ROOT.'/components/com_php/files/'.$filename;
    ...
[47] // evaluate the PHP
[48] echo '&lt;div class=&quot;php_page&quot;&gt;';
[49] if (is_file($path)) {
[50]    include($path);
[51] } else {
[52]    echo '&lt;span class=&quot;note&quot;&gt;Please choose a File&lt;/span&gt;';

shows no filtration, so we can move into
directories. According to several extensions can be observed as
.html, .jpg, .js, which is not true of all .php
