CVE-2001-0045
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 · uneditedThe default permissions for the RAS Administration key in Windows NT 4.0 allows local users to execute arbitrary commands by changing the value to point to a malicious DLL, aka one of the "Registry Permissions" vulnerabilities.
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.

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 · scopedMigrate from Windows NT 4.0 to a currently supported Windows version (Windows 10/11 or Windows Server 2016+)
- 1. Migrate all systems running Windows NT 4.0 to a supported Windows operating system (such as Windows 2000, Windows XP, or later). Windows NT 4.0 has been end-of-life for many years and no longer receives security updates.
- 2. If migration is not immediately possible, identify the RAS Administration registry key (typically located under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\RAS).
- 3. Modify the permissions on the RAS Administration key to remove unnecessary user access - restrict write/Full Control permissions to Administrators only.
- 4. Verify that no unauthorized DLL paths are configured in the registry key values.
- 5. Prioritize migration to a supported operating system as the definitive remediation, as Windows NT 4.0 no longer receives security patches.
