Dns 320
Monthly
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.
Unrestricted file upload in D-Link DNS-320 firmware version 1.0.2 allows unauthenticated remote attackers to upload arbitrary files - including PHP web shells - via the `Filedata[]` parameter of the jQuery Uploadify handler at `/web/jquery/uploader/multi_uploadify.php`. Because the endpoint performs no file-type validation and the underlying server executes PHP, a successful upload can yield full operating system command execution on the device. Publicly available exploit code exists (E:P confirmed in CVSS 4.0 threat component), substantially lowering the barrier to exploitation; KEV status has not been confirmed at time of analysis.
Unrestricted file upload in D-Link DNS-320 1.0.2 exposes the device to remote exploitation through the `/mydlink/multi_uploadify.php` PHP endpoint, where the `Filedata[]` parameter accepts arbitrary file types without validation. Remote unauthenticated attackers can upload malicious files - including PHP webshells - to the device filesystem, potentially achieving code execution on the NAS. A public proof-of-concept exploit is available per VulDB reporting, which elevates the urgency for owners of internet-facing DNS-320 units to act despite the absence of a CISA KEV listing.
Unrestricted file upload in D-Link DNS-320 firmware 1.0.2 allows remote unauthenticated attackers to upload arbitrary files - including executable PHP webshells - via the `/web/function/save_ajax.php` endpoint by manipulating the handler argument. This effectively enables persistent remote code execution on an end-of-life NAS device for which no vendor patch is expected. A public proof-of-concept exploit has been disclosed, lowering the skill barrier for exploitation; however, no CISA KEV listing was identified at time of analysis.
Unrestricted file upload in D-Link DNS-320 NAS firmware 1.0.2 exposes unauthenticated remote attackers to arbitrary PHP file upload via the `/web/jquery/uploader/uploadify.php` endpoint, likely enabling remote code execution on the embedded Linux system. A public proof-of-concept exploit has been released, significantly lowering the skill barrier for exploitation. No vendor patch has been identified, and the device is a legacy product that may be end-of-life, leaving affected deployments without a vendor-supported remediation path.
Unrestricted file upload in D-Link DNS-320 NAS firmware 1.0.2 exposes the /photo_center/php/uploadify.php endpoint to unauthenticated remote attackers who can manipulate the 'Malicious Handler' argument to upload arbitrary files to the device. The vulnerability stems from CWE-434 (Unrestricted Upload of File with Dangerous Type), a class of flaw that on PHP-backed NAS web interfaces frequently enables follow-on code execution by uploading a web shell. A public proof-of-concept exploit is available, elevating the realistic risk beyond what the moderate CVSS 4.0 base score of 6.9 alone would suggest, though no CISA KEV listing confirms active in-the-wild campaigns at time of analysis.
Unrestricted file upload in D-Link DNS-320 NAS firmware 1.0.2 exposes the `/web/web_file/upload.php` endpoint to unauthenticated remote attackers who can upload arbitrary file types - including PHP webshells - enabling effective remote code execution on the device. The CVSS 4.0 base vector confirms no authentication, user interaction, or special attack conditions are required (PR:N/UI:N/AC:L). A public exploit has been disclosed (CVSS 4.0 E:P modifier, corroborated by a referenced Feishu exploit document), and the DNS-320 is an end-of-life device for which no vendor patch has been identified, leaving exposed deployments persistently vulnerable.
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. The vulnerability resides in the UPnP_AV_Server_Path_Del function within /cgi-bin/app_mgr.cgi, exploitable via manipulation of the f_dir parameter. With CVSS 8.8 (High), low attack complexity (AC:L), network accessibility (AV:N), and publicly available exploit code, this represents an elevated threat to approximately 20 legacy D-Link NAS models through firmware versions up to 20260205. No vendor-released patch identified at time of analysis, and many affected models appear to be end-of-life products.
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.

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.
