What it is

D-Link DIR-820 routers contain an OS command injection vulnerability that allows a remote, unauthenticated attacker to escalate privileges to root via a crafted payload with the ping_addr parameter to ping.ccp.

Why we say that

  • EPSS puts exploitation in the next 30 days at 98%
  • CISA's federal remediation deadline (2024-10-21) 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

The impacted product is end-of-life (EoL) and/or end-of-service (EoS). Users should discontinue utilization of the product.
