Noroxi assessment

Priority: Monitor (action score 30/100)

  • 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: 0.24% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: keystone (Debian:11) 2:18.1.0-1+deb11u2; keystone (Debian:12) 2:22.0.2-0+deb12u1; keystone (Debian:13) 2:27.0.0-3+deb13u1.

Low priority for now. Upgrade to keystone (Debian:11) 2:18.1.0-1+deb11u2; keystone (Debian:12) 2:22.0.2-0+deb12u1; keystone (Debian:13) 2:27.0.0-3+deb13u1 or later.
