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
Use of a broken or risky cryptographic algorithm in Smart Switch prior to version 3.7.67.2 allows local attackers to replace the restoring application. User interaction is required for triggering this vulnerability.

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

Smart Switch prior to version 3.7.67.2 uses a broken or risky cryptographic algorithm that allows local attackers to replace the restoring application during the restore process. This enables code injection through application replacement, requiring user interaction to trigger the attack.

MitigationUpdate Smart Switch to version 3.7.67.2 or later to remediate the cryptographic vulnerability. Organizations should verify all devices running Smart Switch are updated and consider additional controls around the application restore process.

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. Check Smart Switch version on Windows
    Open Control Panel > Programs and Features, or check the file properties of SmartSwitch.exe in Program Files/Smart Switch, or query the Windows Registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{AppID} for the DisplayVersion value
    Affected if displayed version is less than 3.7.67.2 or no version entry exists and the application is present
  2. Check Smart Switch version on Mac
    Open Finder > Applications, right-click Smart Switch.app and select Get Info, or run: defaults read /Applications/Smart\ Switch.app/Contents/Info CFBundleShortVersionString
    Affected if version shown is less than 3.7.67.2 or version cannot be determined but Smart Switch.app exists in Applications
  3. Check Smart Switch version on Android
    Open Settings > Apps > Smart Switch, or run: adb shell dumpsys package com.sec.android.app.smartswitch | grep versionName
    Affected if version code is less than 3.7.67.2 or the app is installed without a readable version
  4. Identify all devices with Smart Switch installed
    Use enterprise asset management tools, endpoint detection tools, or manually search device inventories for Samsung Smart Switch installations across your organization
    Affected if any instance of Smart Switch with version below 3.7.67.2 is found

You are affected if Samsung Smart Switch is installed with any version lower than 3.7.67.2 on any Windows, Mac, or Android device in your environment.

Upgrade available Upgrade to 3.7.67.2 or later
Fixed in 3.7.67.2
Interim mitigation

Update Smart Switch to version 3.7.67.2 or later to remediate the cryptographic vulnerability. Organizations should verify all devices running Smart Switch are updated and consider additional controls around the application restore process.

Recommended fix High confidence

3.7.67.2

  1. Check the current version of Smart Switch installed on the device by navigating to Settings > Apps > Smart Switch and noting the version number
  2. Open the Samsung Galaxy Store or visit the official Samsung Smart Switch download page
  3. Search for Smart Switch and update to version 3.7.67.2 or later if an update is available
  4. Alternatively, download the latest version of Smart Switch from Samsung's official support website or Galaxy Store
