CVE-2024-3272

D-Link Multiple NAS Devices Use of Hard-Coded Credentials Vulnerability. Exploitation in the wild is confirmed by CISA, not predicted. Federal agencies were required to remediate by 2024-05-02 (that deadline has passed); treat that date as the outer bound for your own environment. The fix is in the vendor advisory: D-Link Support Announcements, linked below.

Senserva AI Opinion for CVE-2024-3272

The companion to CVE-2024-3273: these same D-Link NAS models (DNS-320L, DNS-325, DNS-327L, DNS-340L) ship with a hard-coded credential, so the attacker does not need to steal or guess anything before injecting commands. Hard-coded credentials in end-of-life hardware are unfixable by design, and the 98 percent EPSS shows scanners are working through the exposed population. CISA confirmed exploitation in April 2024.

Do this: Treat affected D-Link NAS units as permanently compromised infrastructure: migrate the data off and decommission them rather than trying to firewall around a built-in password.

Common questions about CVE-2024-3272

Is CVE-2024-3272 actively exploited?

Yes. CVE-2024-3272 was added to the CISA Known Exploited Vulnerabilities (KEV) catalog on 2024-04-11, which means exploitation in the wild has been confirmed, not predicted. Its EPSS 30-day exploitation probability is 98%.

What is the CISA deadline and required action for CVE-2024-3272?

CISA set the federal (BOD 22-01) remediation due date at 2024-05-02, which has passed; treat any unremediated system as overdue. The verbatim required action: This vulnerability affects legacy D-Link products. All associated hardware revisions have reached their end-of-life (EOL) or end-of-service (EOS) life cycle and should be retired and replaced per vendor instructions.

What fixes CVE-2024-3272?

The authoritative fix is in the vendor advisory: see D-Link Support Announcements for the patched Multiple NAS Devices versions and any workarounds. KEV listing makes this a fix-first item: patch it ahead of higher-CVSS issues nobody is exploiting.
