Noroxi assessment
Priority: Monitor (action score 21/100)
- 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: 3.2% (FIRST EPSS); higher than 88.5% of all records.
- No special conditions are required; it is repeatable.
- Fixed version: nis (Debian:12) 3.9-6.2; nis (Debian:3.0) 3.9-6.1.
Low priority for now. Upgrade to nis (Debian:12) 3.9-6.2; nis (Debian:3.0) 3.9-6.1 or later.
