I. ABOUT THE APPLICATION
________________________

PhotoMap Gallery  is  a   gallery  component  completely
integrated  into  Joomla 1.5.x. Like 'Picasa', 'Flickr',
or 'Panoramio',  you  can  easily  add geo-tags  to your
photos  so  that  you can remember exactly where they're
from using Google Maps.


II. DESCRIPTION
_______________

Some parameters  are not properly sanitised before being
used in SQL queries.


III. ANALYSIS
_____________

Summary:

 A) Multiple Blind SQL Injection
 

A) Multiple Blind SQL Injection
_______________________________

The parameter id passed to controller.php  via POST when
view is set to user and task is set to save_usercategory
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 parameter folder passed to  imagehandler.php  is not
properly sanitised before used in a SQL query.  This can
be  exploited  to  manipulate  SQL  queries by injecting
arbitrary SQL code.

The following is the affected code.

controller.php (line 1135):

function save_usercategory() {

    // Check for request forgeries
	JRequest::checkToken() or jexit( 'Invalid Token' );
		
	$user			= & JFactory::getUser();
	$task			= JRequest::getVar('task');
	$post 			= JRequest::get('post');

	//perform access checks
	$isNew = ($post['id']) ? false : true;

//	$catid = (int) JRequest::getVar('catid', 0);
		
	$db 	=& JFactory::getDBO();
	$query = 'SELECT c.id, c.directory'
				. ' FROM #__g_categories AS c'
				. ' WHERE c.id = '.$post['id'];


imagehandler.php (line 109);

function getList() {

	static $list;

	// Only process the list once per request
	if (is_array($list)) {
		return $list;
	}

	// Get folder from request
	$folder = $this->getState('folder');
	$search = $this->getState('search');

	$query = 'SELECT *'
			. ' FROM #__g_categories'
			. ' WHERE id = '.$folder;
