DescriptionCVE.org

UNSUPPORTED WHEN ASSIGNED A vulnerability, which was classified as critical, 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. Affected is the function cgi_move_photo of the file /cgi-bin/photocenter_mgr.cgi. The manipulation of the argument photo_name leads to buffer overflow. It is possible to launch the attack 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.
