CVE-1999-1563: Nachuatec D435 and D445 printer allows remote attackers to cause a denial of service via ICMP redirect storm.

Security readout for executives and security teams

This is an old denial-of-service issue in Nashuatec/Nachuatec D435 and D445 printers. A remote attacker could disrupt printer availability by triggering an ICMP redirect storm. The source bundle does not provide a CVSS score, patch status, or evidence of active exploitation, so urgency depends mainly on whether these legacy printers remain reachable on business networks. Exposure is likely limited to organizations that still operate Nashuatec/Nachuatec D435 or D445 printers on reachable IP networks. Risk increases if printer management or network control-plane traffic is reachable from untrusted segments. The source bundle does not identify internet-scale exposure or supported versions. Prioritize this only if affected legacy printers remain in production or support critical workflows. There is no supplied CVSS score, KEV listing, patch detail, or active exploitation evidence. For most environments, handle through legacy asset review and network segmentation rather than emergency response. Mitigation focus: Inventory networks for D435 and D445 printer models.; Check vendor or archived advisory guidance for firmware or configuration fixes.; Restrict printer access to trusted internal network segments..
