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 · high confidence

A DLL hijacking vulnerability in Samsung Smart Switch PC allows attackers to execute arbitrary code by placing a malicious DLL in a location where the application searches for DLLs, potentially bypassing authentication and executing code in the context of the logged-on user.

MitigationUpdate Smart Switch PC to version 4.3.22083_3 or later to obtain the patched binary. Ensure application directories are not writable by unprivileged users to prevent DLL planting.

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 Samsung Smart Switch PC is installed
    Check for the application in the system: Look for 'Samsung Smart Switch' in Add/Remove Programs (appwiz.cpl), or check common installation paths such as C:\Program Files\Samsung\Smart Switch or C:\Program Files (x86)\Samsung\Smart Switch
    Affected if The application is not found on the system, then this CVE does not apply
  2. Identify the installed version of Smart Switch PC
    Open Programs and Features, find Samsung Smart Switch PC, and note the version column. Alternatively, right-click the Smart Switch executable (SmartSwitchPC.exe) in the installation folder, select Properties, and check the Details tab for the File Version
    Affected if The displayed version is blank, missing, or cannot be determined
  3. Compare your version against the vulnerable range
    Compare the identified version number to the affected range: any version lower than 4.3.22083_3 is vulnerable. For example, 4.3.22070_1 or any 4.2.x version would be in the affected range
    Affected if The installed version is 4.3.22083_2, 4.3.22070_1, 4.2.x, or any version number less than 4.3.22083_3
  4. Inspect application directory permissions for writable locations
    Right-click the Smart Switch installation folder (e.g., C:\Program Files\Samsung\Smart Switch), select Properties, go to the Security tab, and check which users or groups have Write or Modify permissions on the folder
    Affected if Non-privileged users or the 'Users' group have Write or Modify permissions to the application directory, allowing DLL planting

You are affected if Samsung Smart Switch PC is installed with a version lower than 4.3.22083_3 and the application directory is writable by unprivileged users.
