Integer signedness error in D-Link AirPlus DI-614+ running firmware 2.30 and earlier allows remote attackers to cause a denial of service (IP lease depletion) via a DHCP request with the LEASETIME option set to -1, which makes the DHCP lease valid for thirteen or more years.

Security readout for executives and security teams

This vulnerability can let someone abuse the DHCP service on an affected D-Link AirPlus DI-614+ router so that available IP leases are consumed for an extremely long time. The business impact is network disruption: legitimate users may be unable to obtain an IP address and connect through the router. Exposure is likely limited to legacy D-Link AirPlus DI-614+ routers running firmware 2.30 or earlier, especially where untrusted users can reach the router's DHCP service on the local wired or wireless network. Prioritize remediation if this router still supports a business network, guest Wi-Fi, or any semi-public access. The issue is old and product-specific, but an exposed affected device can still create a practical availability outage. Mitigation focus: Identify and retire affected legacy DI-614+ routers where possible.; Check D-Link or archived vendor guidance for firmware newer than 2.30.; Restrict DHCP access to trusted wired and wireless clients only..
