CVSS 7.3 EPSS 100% no public exploit indexed Fix deadline passed 2 May 2024

What it is

D-Link DNS-320L, DNS-325, DNS-327L, and DNS-340L contain a command injection vulnerability. When combined with CVE-2024-3272, this can lead to remote, unauthorized code execution.

Why we say that

  • EPSS puts exploitation in the next 30 days at 100%
  • CISA's federal remediation deadline (2024-05-02) has passed
  • Listed in the CISA Known Exploited Vulnerabilities catalogue

Every line above comes from a named public source. Where the evidence is thin, we say so rather than inventing confidence — see methodology.

What to do

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 it costs when this goes wrong

This is where UK enforcement meets the vulnerability record. Where an unfixed vulnerability leads to a breach, the ICO treats it as a security failure under UK GDPR. Recent cases:
