NVD · unedited
DLL hijacking vulnerability in Smart Switch PC prior to version 4.2.22022_4 allows attacker to execute abitrary code.

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

This is a DLL hijacking vulnerability in Samsung's Smart Switch PC application. The application loads Dynamic Link Libraries (DLLs) from locations where an attacker can place malicious versions, allowing arbitrary code execution with the privileges of the running user. Attackers can exploit this by placing a specially crafted DLL in a directory from which the application loads libraries.

MitigationUpdate Smart Switch PC to version 4.2.22022_4 or later, which includes the secure DLL loading fix. Verify that no malicious DLLs exist in application directories.

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. Identify installed Smart Switch PC version
    Open Programs and Features (appwiz.cpl) and find Samsung Smart Switch PC in the list, or right-click SmartSwitch.exe in the installation folder and view Properties > Details to see the File Version
    Affected if Version is lower than 4.2.22022_4 (the version shown will be something like 4.1.x or 4.2.x with a lower build number)
  2. Locate the Smart Switch PC installation directory
    Right-click Smart Switch PC in Programs and Features and select Properties, or use Task Manager to find the path of a running SmartSwitch.exe process by right-clicking the process and selecting Open file location
    Affected if Directory is found - this confirms the application is installed on the system
  3. Examine DLL files in the application directory
    Open the Smart Switch PC installation folder and list all .dll files present. Look for DLLs that appear unusual, unexpected, or that were recently added (check the Modified date)
    Affected if Any DLL files exist that are not part of the original Samsung installation or that you did not place there yourself

You are affected if the installed version is below 4.2.22022_4 AND there are untrusted or unexpected DLL files in the Smart Switch PC installation directory that could be exploited for hijacking.
