# CVE-2024-3273: D-Link Multiple NAS Devices Command Injection Vulnerability

**Signal:** Exploited: patch now if you run it. CISA has confirmed exploitation in the wild. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Yes, if you run D-Link Multiple NAS Devices. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2024-04-11, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2024-05-02 ; treat that as the outer limit, not the target.
- EPSS 100.0% , percentile 100.0: FIRST’s model estimates a 100.0% chance of exploitation activity in the next 30 days, higher than 100.0% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.

## What it is

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/nassharing.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.
