CVE-2023-21444
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 cryptographic implementation in Samsung Flow for PC 4.9.14.0 allows adjacent attackers to decrypt encrypted messages or inject commands.
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 confidenceSamsung Flow for PC version 4.9.14.0 contains an improper cryptographic implementation flaw that allows adjacent attackers (within proximity of the device) to either decrypt encrypted messages transmitted through the application or inject arbitrary commands. The vulnerability stems from weak or incorrect cryptographic algorithms, key handling, or initialization vector (IV) usage in the encryption mechanism.

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.
-
Check if Samsung Flow for PC is installedOpen PowerShell and run: Get-ItemProperty 'HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\*', 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Uninstall\*' | Select-Object DisplayName, DisplayVersion | Where-Object {$_.DisplayName -like '*Samsung Flow*'}Affected if Samsung Flow for PC does not appear in the installed programs list
-
Identify the installed version of Samsung Flow for PCReview the DisplayVersion field from the registry query above, or open the Samsung Flow application and go to Settings > About to view the version numberAffected if The installed version number is less than 4.9.14.0
-
Determine if Samsung Flow is actively connected to a paired deviceLaunch Samsung Flow and verify whether a Samsung mobile device is currently paired and actively syncing or connected, as the cryptographic vulnerability affects the encrypted communication channel between the PC and paired deviceAffected if Samsung Flow shows an active connection to a paired Samsung mobile device
A user is affected if Samsung Flow for PC version is below 4.9.14.0 and the application has an active connection to a paired Samsung device, allowing adjacent attackers within proximity to decrypt communications or inject commands.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped4.9.14.0
Apply the vendor-supplied security patch for Samsung Flow for PC to address the cryptographic flaws. If no patch is available, minimize exposure by avoiding use of Samsung Flow in untrusted physical proximity environments.
Flow 4.9.14.0 or later
- Open Samsung Flow for PC
- Navigate to the Settings or Help section within the application
- Check for software updates or version information
- If an update to version 4.9.14.0 or later is available, download and install it
- Restart the application after updating
