CVE-2023-41929
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 · uneditedA DLL hijacking vulnerability in Samsung Memory Card & UFD Authentication Utility PC Software before 1.0.1 could allow a local attacker to escalate privileges. (An attacker must already have user privileges on Windows to exploit 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 · high confidenceThis is a DLL hijacking vulnerability in Samsung Memory Card & UFD Authentication Utility PC Software versions prior to 1.0.1. An attacker with existing local user-level Windows privileges can exploit the application by placing a malicious DLL in a location where the application loads DLLs without proper path validation, allowing execution with elevated privileges.

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.
-
Identify Samsung Memory Card & UFD Authentication Utility installationSearch for the application in Program Files directories (typically C:\Program Files\ or C:\Program Files (x86)\) or use Windows Features/Programs and Features to locate the installed software.Affected if The software is found installed on the system.
-
Determine installed version of the softwareRight-click the application executable or its shortcut, select Properties, and check the Details tab for the Version or File Version field. Alternatively, right-click in Programs and Features, select About to view version info.Affected if The displayed version is lower than 1.0.1 (for example, 1.0.0, 0.x.x, or no version displayed).
-
Verify the vulnerable DLL loading behaviorExamine the application's executable directory and check if it has weak permissions that allow non-privileged users to write files. Use icacls or file explorer security properties to check if Users or Authenticated Users have Write or Modify permissions on the application folder.Affected if Non-admin users can write to the folder where the application executable resides, enabling them to place a malicious DLL.
The system is affected if Samsung Memory Card & UFD Authentication Utility PC Software version is below 1.0.1 and the application directory permits write access to non-privileged users.

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 · scoped1.0.1
Update Samsung Memory Card & UFD Authentication Utility PC Software to version 1.0.1 or later. Alternatively, ensure the application runs from secure directories with controlled write access to prevent attackers from placing malicious DLLs.
1.0.1
- Navigate to the official Samsung Semiconductor website (semiconductor.samsung.com) and locate the Memory Card & UFD Authentication Utility PC Software download page

- Uninstall the current vulnerable version of the software from the Windows system
- Install the newly downloaded version 1.0.1 or later
- Restart the computer if prompted to complete the installation
- Verify the installed version matches 1.0.1 or higher
