Local file vulnerability

Summary

The C lib for 5.6 is compiled with support for local infiles by default. In order to disable the local infile behavior Consumers of the C lib must explicitly set the option MYSQL_OPT_LOCAL_INFILE to 0. The mysql2 gem only sets the MYSQL_OPT_LOCAL_INFILE option when the local_infile key is explicitly present in the Ruby client options. This means that 5.6 clients, which do not specify this key have the local infile behavior enabled making it the default for these clients.

cvgw / Intercom Implementation
Created April 28, 2015 19:43
Here is out implementation of the intercom in app messenger using our custom loader instead of inline JS. Current_user is just a backbone model, which is retrieved by the getMe() method.
this.app.load('intercom', function (root, app) {
'use strict';
var current_user;
var startIntercom = function () {
window.intercomSettings = {
// TODO: The current logged in user's full name
name: current_user.attributes.name,
