MediumCVSS 6.5 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 26/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.36% (FIRST EPSS).
  • Someone on the same network segment can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: firmware-nonfree (Debian:10) 20190114+really20220913-0+deb10u1; firmware-nonfree (Debian:12) 20220913-1.

Low priority for now. Upgrade to firmware-nonfree (Debian:10) 20190114+really20220913-0+deb10u1; firmware-nonfree (Debian:12) 20220913-1 or later.
