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
The ncprwsnt service in NCP Network Communication Secure Client 8.11 Build 146, and possibly other versions, allows local users to execute arbitrary code by modifying the connect.bat script, which is automatically executed by the service after a connection is established.

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

The ncprwsnt service in NCP Secure Client executes connect.bat automatically after establishing a connection. Due to insufficient access controls, local unprivileged users can modify this script to execute arbitrary code with the service's elevated privileges, achieving local privilege escalation.

MitigationRestrict write access to connect.bat to only privileged accounts, and consider moving the script to a protected directory with administrator-only permissions, or implement script integrity verification.

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. Verify NCP Secure Client installation and version
    Check if NCP Secure Client version 8.11_build_146 is installed by reviewing installed programs or checking program directories for NCP Network Communications Secure Client
    Affected if NCP Secure Client version 8.11_build_146 is installed
  2. Confirm ncprwsnt service presence
    Open Services console (services.msc) or run 'sc query ncprwsnt' to check if the NCP RWS NT service exists and is running
    Affected if The ncprwsnt service exists and is configured to run on the system
  3. Locate connect.bat script
    Search for connect.bat in common NCP installation directories such as C:\Program Files\NCP\ or C:\Program Files (x86)\NCP\, or check the service configuration for the executable path
    Affected if connect.bat is found in an NCP installation directory
  4. Verify connect.bat write permissions
    Right-click connect.bat, go to Properties > Security, and check the permissions for non-admin users. Alternatively, run 'icacls connect.bat' from an elevated command prompt to view ACLs
    Affected if Non-privileged users or the Users group have Write or Modify permissions to connect.bat
  5. Check service execution context
    Run 'sc qc ncprwsnt' to view the service configuration, specifically checking the BINARY_PATH_NAME and START_TYPE. Verify if the service runs under a privileged account (like LocalSystem)
    Affected if The ncprwsnt service runs under an elevated account such as LocalSystem or Administrator

A user is affected if NCP Secure Client 8.11_build_146 is installed with the ncprwsnt service running, and connect.bat is writable by non-privileged local users.

Mitigation

Restrict write access to connect.bat to only privileged accounts, and consider moving the script to a protected directory with administrator-only permissions, or implement script integrity verification.
