Sql injections in e107 [Admin section]
Hi,
There are several sql injections in e107 0.7.5 admin section :
I) The "linkopentype", "linkrender" and "link_class" parameters are passed
to "db_Insert()" function without checking :
File /e107_admin/links.php, Line 496 :
>> $sql->db_Insert("links", "0, '$link_name', '$link_url', '$link_description',
>> '$link_button', ".$_POST['linkrender'].", ".($link_t+1).", ".$parent_id.",
>> ".$_POST['linkopentype'].", ".$_POST['link_class']);
II) The "linkopentype", "linkrender", "link_class" and "link_id" parameters
are passed to "db_Update()" and "db_Select()" functions without checking :
File /e107_admin/links.php, Line 480 :
>> $sql->db_Update("links", "link_parent='$parent_id', link_name='$link_name',
>> link_url='$link_url', link_description='$link_description', link_button=
>> '$link_button', link_category='".$_POST['linkrender']."',
>> link_open='".$_POST['linkopentype']."',
>> link_class='".$_POST['link_class']."' WHERE link_id='$id'");
File /e107_admin/links.php, Line 482 :
>> if($sql->db_Select("links", "*", "link_parent='{$id}'"))
POC :
-----
Go to "Admin" -> "Site Links" -> "Edit" section
(/e107_admin/links.php?create.edit.1), and change the values of
"linkopentype", "linkrender", "link_class" and "link_id" inputs.
III) The "searchquery" parameter in file /e107_admin/users.php, line 448
is not checked against sql injection :
>> $_POST['searchquery'] = trim($_POST['searchquery']);
Which make the next query vulnerable .
POC :
-----
Go to users admin section (/e107_admin/users.php), and search for "1' SQL" .
IV) The "download_category_class" parameter is not checked properly before
using in the insert query :
File /e107_admin/download.php, Line 1320 :
>> admin_update($sql->db_Insert("download_category", "0,
>> '$download_category_name', '$download_category_description',
>> '$download_category_icon', '".intval($_POST['download_category_parent'])."',
>> '".$_POST['download_category_class']."', 0 "), 'insert', DOWLAN_47);
These are in administration section, so they dont seem to be critical.
