Belkin F5D5230-4 4-Port Cable/DSL Gateway Router 1.20.000 modifies the source IP address of internal packets to that of the router's external interface when forwarding a request from an internal host to an internal web server, which allows remote attackers to hide which host is being used to access the web server.

Security readout for executives and security teams

This old Belkin gateway can make internal web requests appear to come from the router’s external address. The issue is not described as code execution or data theft, but it can weaken logging, attribution, and source-IP-based controls around an internal web server. Exposure is likely limited to legacy environments still using this exact Belkin router and firmware, especially where internal web servers trust source IP addresses or depend on accurate client IP logging. Treat this as a legacy network hygiene issue. Prioritize if the router still protects or routes traffic for business systems that depend on accurate logging or source-IP controls. Mitigation focus: Inventory for Belkin F5D5230-4 firmware 1.20.000.; Check Belkin or historical vendor guidance for firmware or configuration advice.; Do not rely on source IP alone for internal web authorization..
