CVE-2019-2125
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 ChangeDefaultDialerDialog.java, there is a possible escalation of privilege due to an overlay attack. This could lead to local escalation of privilege, granting privileges to a local app without the user's informed consent, with no additional privileges needed. User interaction is needed for exploitation. Product: Android. Versions: Android-7.0 Android-7.1.1 Android-7.1.2 Android-8.0 Android-8.1 Android-9. Android ID: A-132275252.
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 confidenceIn ChangeDefaultDialerDialog.java on Android 7.0-9, a malicious local app can perform an overlay attack to manipulate the default dialer selection dialog, tricking users into granting default dialer privileges without informed consent, achieving local privilege escalation.

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.
-
Verify Android version is affectedGo to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shellAffected if The version listed is 7.0, 7.1.1, 7.1.2, 8.0, 8.1, or 9.0
-
Check security patch levelGo to Settings > About Phone > Security patch level, or run 'getprop ro.build.version.security_patch' via ADB shellAffected if The patch level is earlier than the date of the A-132275252 fix (or the specific patch date for this CVE is not present)
-
Verify overlay permission is granted to appsGo to Settings > Apps > Special access > Draw over other apps, or run 'adb shell appops get <package> SYSTEM_ALERT_WINDOW' for specific appsAffected if Any untrusted or unfamiliar app is listed with permission to draw over other apps enabled
A device is affected if it runs Android 7.0-9.0 without the A-132275252 security patch and has untrusted apps with overlay (SYSTEM_ALERT_WINDOW) permission enabled.

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 Google Android security patch (A-132275252) for CVE-2019-2125. Until patched, warn users against installing untrusted applications and scrutinize default app permission requests.
