Noroxi assessment

Priority: Monitor (action score 14/100)

  • 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: 0.40% (FIRST EPSS).
  • No special conditions are required; it is repeatable.
  • Fixed version: puppet (Debian:11) 2.7.13-1; puppet (RubyGems) 2.7.13.

Low priority for now. Upgrade to puppet (Debian:11) 2.7.13-1; puppet (RubyGems) 2.7.13 or later.
