Security readout for executives and security teams

CVE-2002-0221 is an availability issue in Etype EServ 2.97. A remote attacker could send many FTP PASV commands and exhaust the server's passive port range, stopping legitimate passive FTP sessions from working. Exposure is likely limited to organizations still running Etype EServ 2.97 with FTP reachable by untrusted networks. The provided data does not identify other affected versions or products. Treat this as a targeted availability risk for legacy FTP infrastructure, not a broad enterprise emergency. Prioritize action if EServ 2.97 supports business workflows or is internet-exposed. Mitigation focus: Inventory for Etype EServ 2.97 and exposed FTP services.; Check vendor or archival guidance for fixed versions or configuration workarounds.; Restrict FTP access to trusted networks where business allows..
