# CVE-2024-3272: D-Link Multiple NAS Devices Use of Hard-Coded Credentials 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 98.1% , percentile 99.9: FIRST’s model estimates a 98.1% chance of exploitation activity in the next 30 days, higher than 99.9% 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 very critical, has been found in D-Link DNS-320L, DNS-325, DNS-327L and DNS-340L up to 20240403. This issue affects some unknown processing of the file /cgi-bin/nassharing.cgi of the component HTTP GET Request Handler. The manipulation of the argument user with the input messagebus leads to hard-coded credentials. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The associated identifier of this vulnerability is VDB-259283. 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.
