't' argument is passed to load_template() function without checks
see load_template() function in /modules/module_parser.php - lines 778-797
...
function load_template($basename) {
global $template_cache, $Paths;
$filename = $Paths['templates_path'].$basename;

}
$filetext=implode("", file($filename)); // <----------------------------|_ lol !!!
$template_cache[$basename]=$filetext;
return $filetext;
}
}
...
our argument is passed to a file() function, so, regardless of php settings,
we can see php files at screen trough directory traversal attacks, including the
configuration file (pv_cfg_settings.php), which cointains the admin credentials
(username/md5 hash/sessions...)
note: 't' can be passed as GET or POST
