CVE-2014-6002

Vulnerability

The DTE Energy Android application (com.dteenergy.mydte) version 3.0.3 does not verify X.509 certificates from SSL servers. This means that when the app establishes an HTTPS connection, it accepts any certificate presented by the server without validating its authenticity against a trusted root certificate authority. The vulnerability affects all users of this version on Android devices.

Exploitation

An attacker must be on the same network as the victim's Android device (e.g., a public Wi-Fi hotspot) and perform a man-in-the-middle (MITM) attack. The attacker can intercept the HTTPS connection by presenting a crafted certificate that the app will accept without validation. No user interaction beyond normal app usage is required; the attacker can then relay or modify traffic between the app and the legitimate server.

Impact

A successful MITM attacker can view or modify network traffic that should have been protected by HTTPS. Possible outcomes include credential stealing (e.g., login credentials for DTE Energy accounts) or arbitrary code execution on the device, depending on the nature of the intercepted data [1]. The attacker gains the ability to spoof the legitimate server and obtain sensitive information.

Mitigation

No official fix has been released for this vulnerability. The CERT/CC recommends not using the affected application and instead accessing DTE Energy services through a web browser, which typically implements proper SSL validation [1]. Users should also ensure their Android device is updated and avoid using untrusted networks for sensitive transactions.
