🤖 AI Analysis

How it works

The vulnerability occurs in the cgi_user_add function handled by the /cgi-bin/account_mgr.cgi?cmd=cgi_user_add file. By manipulating the 'name' parameter sent to this endpoint, an attacker can inject arbitrary system commands that will be executed by the device. The exploit has been publicly released and can be exploited by third parties, although the complexity of carrying out the attack is relatively high.

Impact

An attacker can remotely execute arbitrary operating system commands on the vulnerable NAS device, leading to complete compromise of the device — loss of confidentiality, integrity, and availability of stored data.

Mitigation & patch

Apply patches available from the manufacturer according to the references. Since D-Link DNS-320, DNS-320LW, DNS-325, and DNS-340L models may be devices withdrawn from official support (EoL), it is recommended to isolate these devices from the public network, restrict access to the administrative interface exclusively to trusted IP addresses, and consider migrating to newer, supported hardware.

Who is affected

D-Link DNS-320, DNS-320LW, DNS-325, and DNS-340L in all firmware versions up to and including 20241028
