Noroxi assessment

Priority: Monitor (action score 33/100)

  • 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: 0.51% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: OpenStack keystonemiddleware 10.12.2, 12.0.1, 13.0.2.

Low priority for now. Upgrade to OpenStack keystonemiddleware 10.12.2, 12.0.1, 13.0.2 or later.
