A significant buffer overflow vulnerability exists in D-Link's NAS devices due to improper handling of the photo_name argument in the cgi_move_photo function within the /cgi-bin/photocenter_mgr.cgi script. This weakness permits remote attackers to exploit the flaw, potentially leading to unauthorized control over the affected devices. Notably, this vulnerability affects several models of D-Link NAS devices that have reached end-of-life status and are no longer supported by the vendor. Users are strongly advised to retire these devices and consider upgrading to supported alternatives to maintain network security.
