Summary

VitaFit Android application (com.vt.vitafit) before 2.8.1.0 registers a custom URI scheme that a malicious application can also register, so it can intercept the callback. The flaw is CWE-926, improper export of Android application components. A malicious app installed on the same device can capture a 30-day Fitbit authorization token with weight scope delivered in the callback URL and use it to read, create, and delete the victim's weight and body-fat records through the Fitbit Body API. An exploit link is listed in the references.
