CVE-2017-0423
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 · uneditedAn elevation of privilege vulnerability in Bluetooth could enable a proximate attacker to manage access to documents on the device. This issue is rated as Moderate because it first requires exploitation of a separate vulnerability in the Bluetooth stack. Product: Android. Versions: 5.0.2, 5.1.1, 6.0, 6.0.1, 7.0, 7.1.1. Android ID: A-32612586.
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 · moderate confidenceAn elevation of privilege vulnerability in Android's Bluetooth component enables a proximate attacker to manage access to documents on the device. However, exploitation first requires compromising a separate vulnerability in the Bluetooth stack, making this a chained-attack scenario.

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 Android versionCheck the device or system settings for the Android OS version. On most Android devices: Settings > About Phone > Android version. Or via ADB: `adb shell getprop ro.build.version.release`Affected if The installed Android version is 5.0, 5.0.1, 5.0.2, 5.1, 5.1.0, 5.1.1, 6.0, 6.0.1, 7.0, 7.1.0, or 7.1.1
-
Verify Bluetooth is enabledCheck if Bluetooth functionality is active on the device. On Android: Settings > Bluetooth, or via ADB: `adb shell settings get global bluetooth_on`Affected if Bluetooth is turned ON - this vulnerability affects the Bluetooth component and requires it to be enabled for exploitation
-
Check security patch levelView the installed Android security patch level. On device: Settings > About Phone > Security patch level. Via ADB: `adb shell getprop ro.build.version.security_patch`Affected if The security patch level is earlier than the February 2017 Android security update - this CVE was addressed in the February 2017 Android Security Bulletin (or later)
A device is affected if it runs Android 5.0 through 7.1.1, has Bluetooth enabled, and lacks the February 2017 or later Android security patches.

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 relevant Android security patches for the affected versions (5.0.2 through 7.1.1). As this is a platform-level Bluetooth vulnerability, no user-facing configuration can fully mitigate it; system-level updates are required.
