CVE-2022-39844
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 validation of integrity check vulnerability in Smart Switch PC prior to version 4.3.22083 allows local attackers to delete arbitrary directory using directory junction.
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 confidenceSmart Switch PC versions prior to 4.3.22083 have an improper integrity check validation that allows local attackers to manipulate directory junctions to delete arbitrary directories on the system. This is a local privilege vulnerability requiring the attacker to have local access to the target machine.

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.
-
Locate Smart Switch PC installationSearch for Samsung Smart Switch PC in Program Files (usually C:\Program Files\Samsung\Smart Switch PC) or check Programs and Features in Control PanelAffected if Smart Switch PC is not installed on the system
-
Identify installed versionRight-click the Smart Switch PC executable (SmartSwitchPC.exe), select Properties, and check the File Version on the Details tab. Alternatively, open Programs and Features, find Smart Switch PC, and note the version columnAffected if The version number displayed is lower than 4.3.22083 (e.g., 4.3.xxxx with any build number below 22083)
-
Verify vulnerability applicabilityConfirm that local non-privileged users have access to the system where Smart Switch PC is installed, as exploitation requires local access to manipulate directory junctionsAffected if The system allows local user access and Smart Switch PC version is below 4.3.22083
You are affected if Samsung Smart Switch PC is installed with a version number lower than 4.3.22083 and the system permits local user access.
