Command injection in D-Link's remote backup CGI handler exposes approximately 20 NAS and NVR device models - including DNS-320, DNS-325, DNS-1200-05, and DNS-1550-04 - to remote OS command execution by authenticated low-privilege users. The vulnerable parameter is the 'ip' argument passed to the cgi_check_rsync_rw function in /cgi-bin/remote_backup.cgi, which fails to sanitize shell metacharacters before constructing system commands (CWE-77). No public exploit identified at time of analysis as confirmed CISA KEV listing, but a proof-of-concept has been made public, and most affected devices are likely end-of-life with no patch forthcoming.
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.
Improper access controls in D-Link DNS and DNR network-attached storage devices allow unauthenticated remote attackers on adjacent networks to access IPv6 configuration functions via the cgi_get_ipv6 function in /cgi-bin/network_mgr.cgi, potentially disclosing sensitive network configuration information. The vulnerability affects multiple D-Link models up to firmware version 20260205, publicly available exploit code exists, and the attack requires only network adjacency with low complexity.
Stack-based buffer overflow in D-Link NAS device management interfaces allows authenticated remote attackers to execute arbitrary code with high impact across 21 product models. The vulnerability resides in the cgi_addgroup_get_group_quota_minsize function within /cgi-bin/account_mgr.cgi, exploitable via malicious Name parameter input. Public exploit code exists on GitHub, significantly lowering the technical barrier for attacks. Authentication is required (PR:L), but once authenticated, attackers achieve full confidentiality, integrity, and availability compromise. EPSS and KEV status not provided, but the combination of public POC, network accessibility (AV:N), low complexity (AC:L), and widespread device deployment represents material risk to organizations using affected D-Link NAS products.
Stack-based buffer overflow in D-Link NAS devices allows authenticated remote attackers to achieve complete system compromise with high-confidence exploitation. Affects 20+ D-Link DNS and DNR series network storage products through firmware versions released until February 5, 2026. Publicly available exploit code exists targeting the account_mgr.cgi component, enabling remote code execution with low attack complexity once authenticated. CVSS 8.8 (High) with confirmed proof-of-concept demonstrates practical exploitability despite requiring low-privilege authentication.
Stack-based buffer overflow in D-Link NAS devices enables authenticated remote attackers to execute arbitrary code with full system privileges. Affecting 20+ end-of-life D-Link DNS and DNR network storage models through firmware version 20260205, the flaw resides in the Webdav_Upload_File function within /cgi-bin/webdav_mgr.cgi. Publicly available exploit code exists, significantly lowering the barrier to exploitation. CVSS 8.8 (High) reflects network-accessible attack requiring only low-privilege authentication with no user interaction. Organizations using these legacy devices face immediate risk of complete confidentiality, integrity, and availability compromise.
Stack-based buffer overflow in D-Link NAS devices enables remote code execution with high integrity impact for authenticated users.
