NWFTPD.nlm in the FTP server in Novell NetWare 6.0 before SP4 and 6.5 before SP1 allows user-assisted remote attackers to cause a denial of service (console hang) via a large number of FTP sessions, which are not properly handled during an NLM unload.

Security readout for executives and security teams

This is a legacy denial-of-service issue in Novell NetWare FTP. If an affected server is still running, an attacker could contribute to conditions that hang the server console, disrupting availability rather than stealing data. Exposure is mainly legacy Novell NetWare systems that still run the built-in FTP service. Internet-facing or broadly reachable FTP services are more concerning. Most modern environments are likely unaffected unless old NetWare file servers remain in production or isolated networks. Treat this as a legacy availability risk. Prioritize if NetWare FTP remains business-critical or reachable by untrusted users. Otherwise, handle through legacy system retirement and exposure reduction. Mitigation focus: Upgrade NetWare 6.0 to SP4 or later where still supported.; Upgrade NetWare 6.5 to SP1 or later where still supported.; Review the Novell advisory for any additional vendor-specific guidance..
