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 · unedited
NCP Secure Enterprise Client 13.18 and NCP Secure Entry Windows Client 13.19 have an Untrusted Search Path 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 confidence

Untrusted Search Path vulnerability in NCP Secure Enterprise Client 13.18 and NCP Secure Entry Windows Client 13.19 allows attackers to execute malicious code via DLL hijacking by placing malicious DLLs in directories that the application searches when loading libraries.

MitigationApply vendor patch when available; ensure the application uses secure, controlled paths for DLL loading and implement application control policies to prevent unauthorized DLL placement.

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 NCP client version
    Check the installed version of NCP Secure Enterprise Client or NCP Secure Entry Windows Client via Windows Programs and Features, or by querying the application's About or Help menu
    Affected if Version shown is 13.18 (Enterprise Client) or 13.19 (Entry Client)
  2. Verify DLL search path configuration
    Use process monitoring tools or check application configuration to see which directories the NCP client searches when loading DLLs. Look for whether the current working directory, temp folder, or user-writable paths are included in the DLL search order
    Affected if The application's DLL search path includes directories writable by standard users (such as current directory, Downloads, or temp folders)
  3. Inspect common DLL search directories for suspicious files
    Examine directories that the NCP client may query for DLLs, particularly the application installation directory, system directories, and any user-writable directories in the search path. Look for unexpected or recently placed DLL files with names matching commonly hijacked DLLs
    Affected if Unexpected DLL files exist in directories the NCP client uses for library loading, especially in writable locations
  4. Check application behavior on startup
    Monitor the NCP client process during startup using tools that log DLL loading events, noting which DLLs are loaded and from which paths
    Affected if The application loads DLLs from directories outside the secure, controlled installation path

A user is affected if they have NCP Secure Enterprise Client version 13.18 or NCP Secure Entry Windows Client version 13.19 installed AND the application's DLL search path includes user-writable directories where malicious DLLs could be placed.
