Summary

Multiple D-Link devices (including DNS-120, DNS-320, DNS-323, DNS-345, DNR-326) up to 20260205 have a vulnerability in disk management functions in /cgi-bin/dsk_mgr.cgi. Manipulation leads to improper access controls and the attack can be launched remotely. The exploit is publicly available.

Risk Assessment

A remote attacker can bypass access controls and perform unauthorized operations on disks and volumes. Public exploit availability increases the risk of abuse.

Recommendation

Update D-Link device firmware to a fixed version or remove vulnerable models from network exposure. Restrict access to the CGI interface to trusted networks.
