CVE-2019-15471

Estado: ModificadaMedia (5.5)—

The Xiaomi Mi Mix 2S Android device with a build fingerprint of Xiaomi/polaris/polaris:8.0.0/OPR1.170623.032/V9.5.19.0.ODGMIFA:user/release-keys contains a pre-installed app with a package name of com.qualcomm.qti.callenhancement app (versionCode=27, versionName=8.1.0) that allows other pre-installed apps to perform microphone audio recording via an accessible app component. This capability can be accessed by any pre-installed app on the device which can obtain signatureOrSystem permissions that are required by other other pre-installed apps that export their capabilities to other pre-installed app. This app allows a third-party app to use its open interface to record telephone calls to external storage.
