<input type="submit" class="button" name="save" value="Save">
</form>
</body>
</html>
Impact : Critical as an attacker can change admin email , password, dns ....
Solution :
add this code to the page /edit/user/index.php after the session start
$token = uniqid(mt_rand(), true);
if(!isset($_POST)){
$_SESSION['token'] = $token;
}
if(isset($_POST['token']))
if(!($_SESSION['token'] === $_POST['token'])){
header('location: /error/');
}
}
and at the end of page add
$_SESSION['token'] = $toke;
also don't forget to add this html just in the form on page :
<form id="vstobjects" method="post" name="v_edit_user">
<input type="hidden" name="token" value="<?php echo $_SESSION['token'];?>"/>
