Impacted is an unknown function of the file com/WahooFitness/SYSTM/BuildConfig.java of the component com.WahooFitness.SYSTM. Such manipulation of the argument SEGMENT_WRITE_KEY leads to use of hard-coded cryptographic key . Local access is required to approach this attack. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.
A vulnerability exists in the Wahoo Fitness SYSTM App for Android, in versions up to 7.2.1. The issue arises from a hard-coded Segment write key found in the BuildConfig.java file of the com.WahooFitness.SYSTM component. This key can be extracted through reverse engineering and used to send arbitrary tracking events or modify user profiles via Segment's API. Such exploitation could inject false analytics data, disrupt business intelligence, skew user segmentation, and misuse related downstream systems.
