Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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: 2.1% (FIRST EPSS); higher than 82.1% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: chromium-browser (Debian:6.0) 6.0.472.63~r59945-5+squeeze2.

Low priority for now. Upgrade to chromium-browser (Debian:6.0) 6.0.472.63~r59945-5+squeeze2 or later.
