?><h1>SQL Injection Project - Phase 4</h1>
Your goal in this phase of the project is to try out various sets of strings to narrow down on one that will break <b><u>both</u></b> the SQL Statements given below:
<br /><br />
<code style="background: #ae8; padding: 5px; margin: 10px; border: 1px black solid">
SELECT * FROM sampletable2 WHERE itemname = '<?php echo $_POST["form_itemname"]; ?>';
</code><br /><br /><code style="background: #ae8; padding: 5px; margin: 10px; border: 1px black solid">
SELECT * FROM sampletable2 WHERE itemname = "<?php echo $_POST["form_itemname"]; ?>";
</code>
<br /><br />
When we run that query, we will list all the matching results. Your aim is to list all the records of the table <b>sampletable2</b> when both the queries are executed.
<br />If you want to see all rows of table <b>sampletable2</b>, visit <a href="pahse2.php">phase 2</a> and put the following the text box:<br /><br />
<code style="background: #ae8; padding: 5px; margin: 10px; border: 1px black solid">
1 OR 1 = 1
</code>
<br /><br />
<?php
if(!isset($_SESSION["phase4count"])) {
echo "Welcome to <b>Phase 4</b>!";
$_SESSION["phase4count"] = "0";
$_SESSION["phase4done"] = "false";
} else {
$_SESSION["phase4count"] = strval(intval($_SESSION["phase4count"]) + 1);
echo "You've viewed this <b>{$_SESSION["phase4count"]} time(s)</b>!";
}
?>
<br /><br />
<form method="POST">
<input type="text" name="form_itemname" style="width:500px" />
<br />
<input type="submit" value="Crack open the secrets..." />
</form>
<br />
<?php
