D-Link DSL-2750B Devices Command Injection Vulnerability

D-Link · DSL-2750B Devices

CVSS 9.8 EPSS 63% no public exploit indexed Fix deadline passed 29 January 2024

What it is

D-Link DSL-2750B devices contain a command injection vulnerability that allows remote, unauthenticated command injection via the login.cgi cli parameter.

Why we say that

  • EPSS puts exploitation in the next 30 days at 63%
  • CISA's federal remediation deadline (2024-01-29) has passed
  • CVSS 9.8 critical
  • 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

Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
