CVE-2019-2193
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 · uneditedIn WelcomeActivity.java and related files, there is a possible permissions bypass due to a partially provisioned Device Policy Client. This could lead to local escalation of privilege, leaving an Admin app installed with no indication to the user, with User execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-8.0 Android-8.1 Android-9 Android-10Android ID: A-132261064
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 confidenceA permissions bypass in Android's Device Policy Client provisioning flow (WelcomeActivity.java) allows a partially provisioned state where a device admin app can be installed without proper user notification or consent. This enables local privilege escalation by installing a hidden admin component with elevated privileges.

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.
-
Check Android OS versionGo to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shellAffected if The version is 8.0, 8.1, 9.0, or 10.0 (exact matches as listed in affected products)
-
Check security patch levelGo to Settings > About Phone > Security patch level, or run 'getprop ro.build.version.security_patch' via ADB shellAffected if The security patch level is earlier than the fix date for CVE-2019-2193 (the fix was included in Android 8.0-10 security updates)
-
Verify device admin apps were properly provisionedGo to Settings > Security > Device admin apps, or run 'dumpsys device_policy' via ADB shell to list active administratorsAffected if Any device admin app is present without documented user consent during initial device setup, or admin apps appear in a partially provisioned state
-
Review provisioning flow integrityCheck system logs (logcat) around Device Policy Client/WelcomeActivity for provisioning events using 'logcat -d | grep -i welcomeactivity' or 'logcat -d | grep -i provisioning' via ADBAffected if Provisioning completed without visible user consent dialogs or WelcomeActivity user interface was bypassed during device setup
A device is affected if it runs Android 8.0, 8.1, 9.0, or 10.0 with a security patch level predating the fix, and has device admin apps installed through a provisioning flow that lacked proper user notification or consent.

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 the Android security patch level that addresses this vulnerability (fixed in Android 8.0-10 security updates). For custom ROMs or AOSP-based implementations, review and patch the device policy provisioning flow in WelcomeActivity.java to enforce complete user consent before admin activation.
