CVE-2016-10536 Information

Description

engine.io-client is the client for engine.io the implementation of a transport-based cross-browser/cross-device bi-directional communication layer for Socket.IO. The vulnerability is related to the way that node.js handles the rejectUnauthorized setting. If the value is something that evaluates to false certificate verification will be disabled. This is problematic as engine.io-client 1.6.8 and earlier passes in an object for settings that includes the rejectUnauthorized property whether it has been set or not. If the value has not been explicitly changed it will be passed in as null resulting in certificate verification being turned off.
