CVE-2024-7922
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability was found in D-Link DNS-120, DNR-202L, DNS-315L, DNS-320, DNS-320L, DNS-320LW, DNS-321, DNR-322L, DNS-323, DNS-325, DNS-326, DNS-327L, DNR-326, DNS-340L, DNS-343, DNS-345, DNS-726-4, DNS-1100-4, DNS-1200-05 and DNS-1550-04 up to 20240814 and classified as critical. Affected by this issue is the function cgi_audio_search/cgi_create_playlist/cgi_get_album_all_tracks/cgi_get_alltracks_editlist/cgi_get_artist_all_album/cgi_get_genre_all_tracks/cgi_get_tracks_list/cgi_set_airplay_content/cgi_write_playlist of the file /cgi-bin/myMusic.cgi. The manipulation leads to command injection. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. NOTE: This vulnerability only affects products that are no longer supported by the maintainer. NOTE: Vendor was contacted early and confirmed that the product is end-of-life. It should be retired and replaced.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisUser input reaches a command interpreter without being fully separated from the command itself, so an attacker can append instructions of their own. Because those run with the application's privileges, it frequently means control of the host. The lasting fix is to avoid constructing commands from input — call APIs directly and pass arguments as data, never as concatenated strings.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped- 1. Identify all D-Link devices in the environment matching the affected models: DNS-120, DNR-202L, DNS-315L, DNS-320, DNS-320L, DNS-320LW, DNS-321, DNR-322L, DNS-323, DNS-325, DNS-326, DNS-327L, DNR-326, DNS-340L, DNS-343, DNS-345, DNS-726-4, DNS-1100-4, DNS-1200-05, DNS-1550-04.
- 2. Note the firmware version date 20240814 as the vulnerability disclosure point - any device running firmware dated on or before this date is vulnerable.
- 3. Discontinue use of these devices as they have reached end-of-life status and will not receive security patches.
- 4. Replace affected devices with currently supported hardware from D-Link or an alternative vendor.
- 5. If immediate replacement is not possible, isolate these devices on a restricted network segment with firewall rules blocking external access to HTTP/HTTPS services on the CGI interface.
- 6. Monitor for any unauthorized access attempts targeting the /cgi-bin/myMusic.cgi endpoint.
Generated from the published advisory — verify against the referenced sources before acting.
There is no version to upgrade to and no patch to apply. Every affected install stays exposed until the vendor ships a fix — or somebody else builds one.
Free. We build fixes in the order the community asks for them — and we’ll tell you the moment this one lands.
We develop and verify an original fix where the vendor hasn’t, from $3,550. Deployed to your staging first — never straight to production.
