Noroxi assessment
Priority: Monitor (action score 4/100)
- 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).
- Special conditions such as timing or configuration are required.
- Fixed version: samba (Debian:12) 2.2.8; samba (Debian:3.0) 2.2.3a-12.1.
Low priority for now. Upgrade to samba (Debian:12) 2.2.8; samba (Debian:3.0) 2.2.3a-12.1 or later.
