CVE-2003-1592
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 · uneditedMultiple buffer overflows in NWFTPD.nlm in the FTP server in Novell NetWare 6.0 before SP4 and 6.5 before SP1 allow remote attackers to cause a denial of service (abend) via a long (1) username or (2) password.
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 confidenceBuffer overflow vulnerability in NWFTPD.nlm FTP server component of Novell NetWare 6.0 (before SP4) and 6.5 (before SP1). Remote attackers can trigger denial of service by sending excessively long username or password strings during FTP authentication, causing the system to abend.

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 NetWare versionAt the server console, type 'version' or check the startup screen during boot to confirm if NetWare 6.0 or 6.5 is runningAffected if The system is running NetWare 6.0 or 6.5 (other versions are not affected)
-
Check installed service packAt the server console, type 'spinfo' or check the system documentation to determine the installed service pack level. For NetWare 6.0, verify if SP4 or later is installed. For NetWare 6.5, verify if SP1 or later is installedAffected if NetWare 6.0 is at SP3 or earlier, OR NetWare 6.5 is at a version before SP1
-
Verify NWFTPD.nlm is loadedAt the server console, type 'modules' or 'nlm' to list loaded modules. Look for NWFTPD.nlm in the list of running NLM modulesAffected if NWFTPD.nlm is loaded and running on the system
-
Confirm FTP service is accessibleFrom a remote system, attempt to connect to the FTP port (default 21) on the NetWare server IP address using a tool like 'ftp' or 'telnet'Affected if The FTP service accepts connections from network clients
You are affected if the system runs NetWare 6.0 before SP4 or NetWare 6.5 before SP1, has NWFTPD.nlm loaded, and the FTP service is network-accessible.

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 the appropriate service pack: NetWare 6.0 SP4 or NetWare 6.5 SP1 or later. If patching is not feasible, restrict network access to the FTP service via firewall or ACLs.
