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
A weakness has been identified in i-SENS SmartLog App up to 2.6.8 on Android. This affects an unknown function of the component air.SmartLog.android. This manipulation causes hard-coded credentials. The attack can only be executed locally. The exploit has been made available to the public and could be used for attacks. The vendor explains: "The function referenced in the report currently exists in our deployed system. It is related to a developer mode used during the configuration process for Bluetooth pairing between the blood glucose meter and the SmartLog application. This function is intended for configuration purposes related to device integration and testing. (...) [I]n a future application update, we plan to review measures to either remove the developer mode function or restrict access to it."

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

The i-SENS SmartLog App up to version 2.6.8 on Android contains hard-coded credentials in the air.SmartLog.android component. These credentials are associated with a developer mode function intended for Bluetooth pairing configuration between the blood glucose meter and the SmartLog application. The vulnerability is locally exploitable and a public exploit is available.

MitigationUpdate to a patched version of the SmartLog application once released. The vendor plans to either remove or restrict access to the developer mode function. Until then, avoid using the application in untrusted environments.

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. Verify SmartLog app installation
    Open Android Settings > Apps > Apps and search for 'SmartLog' or 'i-SENS', or use ADB command: adb shell pm list packages | grep -i smartlog
    Affected if The package air.SmartLog.android is present on the device
  2. Check installed app version
    In Android Settings > Apps > SmartLog > App info, view the Version number. Alternatively, use ADB: adb shell dumpsys package air.SmartLog.android | grep versionName
    Affected if Version is 2.6.8 or any version prior to 2.6.8 (the affected range)
  3. Confirm developer mode accessibility
    Open the SmartLog app and navigate through the settings or menu options to locate any developer mode, Bluetooth configuration, or pairing-related functions. Check if such a function is exposed or can be activated.
    Affected if Developer mode function for Bluetooth pairing configuration is present and accessible within the application
  4. Assess usage environment
    Review whether the app is being used in untrusted or shared environments where local access by potentially malicious actors is possible, since this is a locally exploitable vulnerability
    Affected if The device or app is used in environments where unauthorized local access is plausible

A user is affected if the i-SENS SmartLog App version 2.6.8 or earlier is installed and the developer mode function for Bluetooth pairing remains accessible on the device.
