CVE-2019-15457
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 J6 Android device with a build fingerprint of samsung/j6ltexx/j6lte:8.0.0/R16NW/J600FNXXU3ASC1: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 J6 Android device (build R16NW) ships with a pre-installed themecenter app (com.samsung.android.themecenter v7.0.0.0) that exposes an accessible app component allowing other pre-installed apps to perform app installation. This capability is accessible to any pre-installed app holding signatureOrSystem permissions, representing a privilege escalation where system-level app installation functionality is improperly exposed to other pre-installed applications.

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.
-
Confirm device modelCheck the device settings to verify the model is Samsung Galaxy J6Affected if Device is a Samsung Galaxy J6 and the themecenter app is present
-
Verify themecenter app presenceCheck installed apps for com.samsung.android.themecenterAffected if The themecenter app version 7.0.0.0 is installed
-
Check firmware versionCheck Android settings for build number (R16NW mentioned in CVE)Affected if Running any firmware version on the Galaxy J6
-
Identify privileged pre-installed appsEnumerate pre-installed apps and check which hold signatureOrSystem permissionsAffected if Any pre-installed app with signatureOrSystem permissions exists alongside the vulnerable themecenter component
A Samsung Galaxy J6 device with the themecenter app (v7.0.0.0) installed and any pre-installed app holding signatureOrSystem permissions is affected by this privilege escalation.
Generated from the published advisory. Verify against your own configuration.
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 dataSamsung should release a firmware update that removes or properly secures the exposed component in the themecenter app. Users should apply available device updates. Until then, the attack surface is limited to other pre-installed apps, not third-party applications.
