Noroxi assessment

Priority: Monitor (action score 24/100)

  • 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: 0.17% (FIRST EPSS).
  • Someone with local access to the system can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: HashiCorp Nomad 2.0.1; HashiCorp Nomad Enterprise 1.10.11, 1.11.5, 2.0.1.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to HashiCorp Nomad 2.0.1; HashiCorp Nomad Enterprise 1.10.11, 1.11.5, 2.0.1 or later.
