CVE-2019-15462
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe Samsung J7 Duo Android device with a build fingerprint of samsung/j7duolteub/j7duolte:8.0.0/R16NW/J720MUBS3ASB2:user/release-keys contains a pre-installed app with a package name of com.samsung.android.themecenter app (versionCode=7000000, versionName=7.0.0.0) that allows other pre-installed apps to perform app installation 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 exported their capabilities to other pre-installed app.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Samsung J7 Duo Android device ships with a pre-installed com.samsung.android.themecenter app (v7.0.0.0) containing an exported component that allows other pre-installed apps to perform app installation. This represents a local privilege escalation within the pre-installed app ecosystem, exploiting signatureOrSystem permissions to bypass normal app installation controls.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify device modelCheck the device settings or use 'getprop ro.product.model' command to confirm the exact model numberAffected if Device model is Samsung Galaxy J7 Duo (or model numbers like SM-J720F, SM-J720M, etc.)
-
Verify themecenter app presenceCheck if com.samsung.android.themecenter package exists using package manager: 'pm list packages | grep themecenter' or via ADBAffected if The com.samsung.android.themecenter package is installed on the device
-
Confirm themecenter versionQuery the app version using 'dumpsys package com.samsung.android.themecenter' or through device settings under Apps > Themecenter > VersionAffected if Version is 7.0.0.0 (the vulnerable version) or any version on the J7 Duo firmware since all versions are affected
-
Verify exported component exposureAnalyze the APK for exported Activity/Service components with signatureOrSystem permissions using tools like 'aapt dump badging' or decompile the APK and check AndroidManifest.xmlAffected if The app contains exported components that allow other pre-installed apps to trigger app installation without user consent
User is affected if running a Samsung Galaxy J7 Duo device with the com.samsung.android.themecenter app present, as the vulnerability exists in all firmware versions of this specific model.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply Samsung security updates for CVE-2019-15462; for end-of-life devices without updates, consider device replacement or enterprise mobility controls to restrict app installation capabilities.
