DescriptionNVD

A weakness has been 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. Affected by this vulnerability is the function FMT_restart/Status_HDInfo/SMART_List/ScanDisk_info/ScanDisk/volume_status/Get_Volume_Mapping/FMT_check_disk_remount_state/FMT_rebuildinfo/FMT_result_list/FMT_result_list_phy/FMT_get_dminfo/FMT_manually_rebuild_info/Get_current_raidtype of the file /cgi-bin/dsk_mgr.cgi. Executing a manipulation can lead to improper access controls. It is possible to launch the attack remotely. The exploit has been made available to the public and could be used for attacks.

AnalysisAI

Improper access controls in D-Link network-attached storage devices (DNS-120 through DNS-1550-04, firmware versions up to 20260205) allow remote unauthenticated attackers to manipulate disk management functions via the /cgi-bin/dsk_mgr.cgi endpoint, resulting in availability impact. Publicly available exploit code exists and the vulnerability has moderate real-world exploitability (CVSS 5.5, EPSS probability indicated by E:P vector), requiring no authentication or user interaction for remote attack.
