CVE-2021-25423
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 · uneditedImproper log management vulnerability in Watch Active2 PlugIn prior to 2.2.08.21033151 version allows attacker with log permissions to leak Wi-Fi password connected to the user smartphone via log.
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 confidenceThe Watch Active2 PlugIn application improperly logs sensitive data, allowing an attacker with log permissions to read Wi-Fi passwords stored on or used by the paired smartphone. The vulnerability stems from the plugin writing credential information to accessible log files without sanitization or encryption.

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.
-
Confirm Watch Active2 Plugin is installedLocate the Samsung Watch Active2 Plugin application on the paired smartphone or connected device. On Android, this can be verified through Settings > Apps > Watch Active2 Plugin, or via the Galaxy Store app under My Downloads.Affected if The application is present on the device
-
Check installed plugin versionAccess the app information screen for Watch Active2 Plugin (Settings > Apps > Watch Active2 Plugin > App info) and note the version number displayed. Compare this version to the vulnerable range: any version prior to 2.2.08.21033151 is affected.Affected if The installed version is lower than 2.2.08.21033151
-
Verify log file accessibilityExamine the log files generated by the Watch Active2 Plugin. On Android, these are typically stored in the application data directory or external storage under log folders. Check file permissions to determine if the log files are readable by other applications or users.Affected if Log files are world-readable or accessible to untrusted applications
-
Inspect logs for credential exposureOpen the Watch Active2 Plugin log files and search for patterns indicating stored Wi-Fi passwords or network credentials. Look for plaintext sensitive strings in the log content that may have been written without sanitization.Affected if Wi-Fi passwords or credential data appear in plaintext within the log files
The environment is affected if Watch Active2 Plugin is installed with a version lower than 2.2.08.21033151 and the application logs are accessible to unauthorized parties.
