Vulnerability Note VU#713312

Original Release Date: 2016-03-11 | Last Revised: 2016-03-14

Overview

The DTE Energy Insight app API allows an authenticated user to obtain and query certain limited customer information from other customers.

Description

CWE-200: Information Exposure - CVE-2016-1562

The DTE Energy Insight app lets DTE Energy customers track their energy usage. This information is exposed via an HTTP REST API.

The API contains a parameter 'filter' that may be manipulated by an authenticated user. This parameter determines the customer data to be returned by the server. By manipulating the 'filter' parameter, an authorized user may be able to obtain and query limited customer information for other users.

The researcher has released a blog post with more details.

Impact

A remote, authenticated user may be able to obtain limited information about other customers.

Solution

DTE Energy has updated its Insight server backend to mitigate this issue. The researcher has confirmed that the APIs no longer allow access to other data.
