Security readout for executives and security teams
This CVE describes a file-read weakness in the TFTP server of the D-Link DIR-601 Wireless N150 Home Router running firmware 1.02NA. A remote attacker may be able to read arbitrary files from the device. The public bundle does not provide CVSS scoring, patch details, or confirmed exploitation. Exposure is likely limited to environments still using D-Link DIR-601 routers with firmware 1.02NA where TFTP is reachable from untrusted networks or adjacent users. The provided affected-product metadata is incomplete, so asset confirmation is important. Treat this as a legacy network-device risk. It is not KEV-listed in the bundle, but arbitrary file read on a router can expose sensitive configuration data. Prioritize locating affected devices and removing unnecessary TFTP exposure. Mitigation focus: Identify any D-Link DIR-601 devices and confirm firmware version 1.02NA.; Check current D-Link guidance for firmware updates, retirement, or replacement advice.; Restrict TFTP reachability to trusted management networks where possible..
