Deeper analysis
CVE-2024-7922 is a command-injection vulnerability (CWE-77) affecting the myMusic.cgi endpoint on numerous end-of-life D-Link NAS models, including DNS-120, DNR-202L, DNS-315L, DNS-320 through DNS-345, DNR-322L, DNR-326, and the DNS-726/1100/1200/1550 series, all firmware versions up to 20240814. Unauthenticated manipulation of the cgi_audio_search, cgi_create_playlist, cgi_get_tracks_list and related CGI functions allows arbitrary command execution on the device.
An attacker with network access and valid credentials for a low-privileged account can send crafted HTTP requests to the affected CGI handlers, resulting in remote command execution with the privileges of the web server process. Public proof-of-concept code for several of the listed functions has already been released.
D-Link’s security advisory SAP10383 and vendor statements confirm that all listed products reached end-of-life status prior to disclosure; no patches will be issued and users are advised to retire the devices. The associated EPSS score rose from a low baseline to a peak of 0.2108, indicating measurable post-disclosure exploitation interest that warrants renewed attention for any remaining deployed units.
