CVE-2003-1593
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 · uneditedNWFTPD.nlm in the FTP server in Novell NetWare 6.0 before SP4 and 6.5 before SP1 does not enforce domain-name login restrictions, which allows remote attackers to bypass intended access control via an FTP connection.
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 confidenceNWFTPD.nlm, the FTP server component in Novell NetWare 6.0 and 6.5, fails to enforce domain-name-based login restrictions, allowing remote attackers to bypass intended access controls by connecting directly via FTP without proper domain validation.

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 the NetWare versionCheck the system information to confirm if the server is running Novell NetWare 6.0 or 6.5 by examining the OS version through the console or system utilitiesAffected if The server is running NetWare 6.0 or 6.5 and is therefore in the affected version range
-
Verify NWFTPD.nlm is loadedAt the NetWare server console, type 'modules' or 'nlm' to list loaded modules and confirm NWFTPD.nlm is currently runningAffected if NWFTPD.nlm is loaded and active as the FTP server component
-
Check if domain-based login restrictions are configuredExamine the FTP server configuration files or access control settings to determine whether domain-name-based login restrictions or ACLs have been defined for FTP accessAffected if Domain-based login restrictions are configured but the system allows FTP connections without validating the domain, indicating the bypass vulnerability is present
-
Attempt FTP connection from non-domain sourceFrom an external IP or system outside the controlled domain, attempt to connect via FTP to the NetWare server and observe whether access is granted without domain validationAffected if FTP access is granted without domain validation, confirming the bypass vulnerability is exploitable
A NetWare 6.0 or 6.5 server running NWFTPD.nlm with domain-based login restrictions configured but not properly enforced is affected by this CVE.

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.
From vendor dataApply NetWare 6.0 SP4 or NetWare 6.5 SP1 (or later) to patch the NWFTPD.nlm vulnerability, and verify that domain-based access control lists are properly enforced after patching.
