CVE-2002-2432
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 · uneditedUnspecified vulnerability in NWFTPD.nlm before 5.03b in the FTP server in Novell NetWare allows remote attackers to cause a denial of service (abend) via a crafted username.
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 · moderate confidenceDenial of service vulnerability in Novell NetWare FTP server (NWFTPD.nlm) allows remote attackers to crash the system (abend) by sending a specially crafted username to the FTP service. The vulnerability exists in versions prior to 5.03b.

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.
-
Verify NWFTPD.nlm is loadedOn the NetWare server console, type 'modules' or '.nlm' to list loaded NLMs. Look for NWFTPD.nlm in the list.Affected if NWFTPD.nlm appears in the loaded modules list
-
Check NWFTPD.nlm versionAt the NetWare server console, type 'nlm /v nwftpd.nlm' or check the file version of NWFTPD.nlm in the system directory (typically SYS:SYSTEM\).Affected if The version displayed is 5.01i, 5.01o, 5.01w, 5.01y, 5.02b, 5.02i, 5.02r, or any version 5.02y or lower (prior to 5.03b)
-
Confirm NetWare versionAt the NetWare server console, type 'version' or check the NetWare operating system version.Affected if Any NetWare version is listed (the CVE states all versions are affected if running vulnerable NWFTPD.nlm)
-
Verify FTP service is enabledAt the NetWare server console, type 'nfsi' or 'config nwftpd' to verify the FTP service is enabled and running.Affected if FTP service shows as enabled or running
If NWFTPD.nlm is loaded and its version is 5.03b or later, the system is not affected by this CVE. If the version is 5.02y or lower, or any of the specific versions listed (5.01i, 5.01o, 5.01w, 5.01y, 5.02b, 5.02i, 5.02r), the system is vulnerable when FTP service is enabled.

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 dataUpgrade NWFTPD.nlm to version 5.03b or later. If the NetWare system cannot be upgraded, restrict FTP access to trusted IP addresses via network filtering or disable the FTP service until patching is possible.
