CVE-2026-5215 Details
Description
A vulnerability was identified 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 20260205. The impacted element is the function cgi_get_ipv6 of the file /cgi-bin/network_mgr.cgi. Such manipulation leads to improper access controls. The exploit is publicly available and might be used.
A vulnerability exists in multiple D-Link NAS devices, including the DNS-120, DNR-202L, DNS-315L, DNS-320 series, 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, all versions prior to 20260205. The issue arises in the 'cgi_get_ipv6' function within the '/cgi-bin/network_mgr.cgi' file, where improper access controls allow unauthenticated users to access sensitive IPv6 configuration data. This data disclosure can lead to an understanding of the device's internal IPv6 network topology and interface layout.
