CVE-2026-5311 Details
Description
A security flaw has been discovered 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 is the function Webdav_Access_List of the file /cgi-bin/file_center.cgi. Performing a manipulation of the argument cmd results in improper access controls. It is possible to initiate the attack remotely. The exploit has been released to the public and may be used for attacks.
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 prior to the version 20260205. The issue arises in the 'Webdav_Access_List' function within the '/cgi-bin/file_center.cgi' file, where improper access controls allow unauthenticated users to access WebDAV access information. This vulnerability can be exploited remotely, leading to the unauthorized disclosure of structured configuration data, including shared directory names, WebDAV access URLs, and the device's internal IPv4 address. Such information could be used to enumerate shared resources and exposed WebDAV endpoints, potentially facilitating further unauthorized access and attacks.
