Executive Summary

This vulnerability exists in the Wahoo Fitness SYSTM App up to version 7.2.1 on Android. It involves an unknown function in the file com/WahooFitness/SYSTM/BuildConfig.java within the component com.WahooFitness.SYSTM. The issue arises because the argument SEGMENT_WRITE_KEY is manipulated, leading to the use of a hard-coded cryptographic key. Exploiting this vulnerability requires local access to the device.

Impact Analysis

The impact of this vulnerability is limited due to the requirement of local access and the low severity scores (CVSS v3.1 BaseScore 3.3). The main consequence is that the use of a hard-coded cryptographic key could potentially allow an attacker with local access to compromise some confidentiality aspects of the application. However, there is no impact on integrity or availability.
