A vulnerability was detected in Verkehrsauskunft Österreich SmartRide, cleVVVer and BusBahnBim up to 12.1.1(258). The impacted element is an unknown function of the file AndroidManifest.xml. The manipulation results in improper export of android application components. The attack must be initiated from a local position. The exploit is now public and may be used. Upgrading to version 12.1.2(259) is sufficient to resolve this issue. Upgrading the affected component is recommended. The vendor was contacted early and fixed the issue by "[r]emoving the task affinity of the app so it can't be copied".
The Android application exports a component for use by other applications, but does not properly restrict which applications can launch the component or access the data it contains.
