Stack-based buffer overflow in D-Link NAS devices (DNS-120, DNR-202L, DNS-315L, DNS-320 series, DNS-326, DNS-1100-4, and others) through the UPnP_AV_Server_Path_Setting function in /cgi-bin/app_mgr.cgi allows authenticated remote attackers to achieve complete system compromise with high integrity, confidentiality, and availability impact. Public exploit code exists for this vulnerability, and no patch is currently available.

Stack-based buffer overflow in D-Link DNS storage appliances (DNS-120, DNS-340L, DNS-1200-05 and others) through the /cgi-bin/gui_mgr.cgi endpoint allows remote authenticated attackers to achieve code execution. Public exploit code exists for this vulnerability, and no patch is currently available. Affected firmware versions are dated up to February 5, 2026.

Stack-based buffer overflow in D-Link DNS NAS devices (DNS-120 through DNS-1550-04) allows authenticated attackers to achieve remote code execution via the Downloads_Schedule_Info function in /cgi-bin/download_mgr.cgi. Public exploit code exists for this vulnerability, and no patch is currently available. The attack requires valid credentials but can be executed over the network with high impact on confidentiality, integrity, and availability.

Stack-based buffer overflow in D-Link DNS and DNR network storage devices allows authenticated remote attackers to execute arbitrary code by manipulating the f_idx parameter in the local_backup_mgr.cgi endpoint. Public exploit code exists for this vulnerability, which affects multiple device models up to firmware version 20260205 with no patch currently available. An attacker with valid credentials can trigger memory corruption to achieve complete system compromise including code execution, data theft, and service disruption.

Command injection in D-Link NAS devices (DNS-320, DNS-327L, DNS-345 and others) through the time_machine.cgi script allows authenticated remote attackers to execute arbitrary commands with network access. Public exploit code exists for this vulnerability, and no patch is currently available.

Command injection in D-Link NAS devices (DNS-120, DNS-325, DNR-322L, DNS-327L and others) allows authenticated remote attackers to execute arbitrary commands through multiple user and group management CGI functions. Public exploit code exists for this vulnerability, and patches are not currently available. An attacker with valid credentials could leverage this to compromise the NAS system and potentially access or manipulate stored data.

Command injection in D-Link NAS devices (DNS-320, DNS-325, DNS-343, DNR-322L and others) through the /cgi-bin/system_mgr.cgi interface allows authenticated remote attackers to execute arbitrary commands. Public exploit code exists for this vulnerability, and no patch is currently available.

A security vulnerability in A flaw (CVSS 6.3). Risk factors: public PoC available.

Command injection in D-Link DNS and DNR network attached storage devices allows authenticated remote attackers to execute arbitrary commands through multiple CGI functions in the network management interface. The vulnerability affects numerous models up to firmware version 20260205, and public exploit code is available. An attacker with valid credentials can leverage this to compromise device integrity and potentially access the network.
