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 · unedited
An issue was discovered on Samsung mobile devices with L(5.0/5.1), M(6.0), and N(7.0) software. Attackers can read the password of the Mobile Hotspot in the log because of an unprotected intent. The Samsung ID is SVE-2016-7301 (December 2016).

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 confidence

Samsung mobile devices with L, M, and N software contain an unprotected Android intent that allows any app to query and retrieve the Mobile Hotspot password, which is also being written to system logs in plaintext. This enables local privilege escalation where a malicious application can obtain the Wi-Fi hotspot credentials without any user permission.

MitigationApply the December 2016 Samsung security update (SVE-2016-7301) or later. If patching is not possible, avoid using Mobile Hotspot on affected devices and monitor for unauthorized access to the intent data.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm device manufacturer is Samsung
    Check device settings under 'About phone' or run 'getprop ro.product.brand' in ADB shell to verify the manufacturer
    Affected if Device is not a Samsung product - the vulnerability only affects Samsung mobile devices
  2. Check Android OS version
    Check Settings > About phone > Android version or run 'getprop ro.build.version.release' in ADB shell
    Affected if Version is NOT 5.0, 5.1, 6.0, or 7.0 - only these specific versions are affected according to the CVE
  3. Determine if Mobile Hotspot has been used
    Check if the Mobile Hotspot feature has been configured or enabled on the device. Look for hotspot settings under Settings > Network & Internet > Mobile Network > Access Point Names or Settings > Connections > Mobile Hotspots, or check for recent hotspot-related log entries
    Affected if Mobile Hotspot has never been configured or used - the vulnerability requires the hotspot feature to be active to expose the password
  4. Inspect system logs for plaintext hotspot password
    Run 'logcat -d | grep -i hotspot' or 'logcat -d | grep -i password' in ADB shell to search for plaintext Wi-Fi credentials in logcat output. Filter for entries containing 'MobileHotspot' or 'ap.*password' patterns
    Affected if Log entries contain plaintext Wi-Fi hotspot passwords in plain text - this indicates the vulnerability is present and the password has been logged

A user is affected if they have a Samsung device running Android 5.0, 5.1, 6.0, or 7.0 where Mobile Hotspot has been used and plaintext passwords appear in system logs.
