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: 2.1% (FIRST EPSS); higher than 82.8% of all records.
- No special conditions are required; it is repeatable.
- Fixed version: icecast2 (Debian:12) 2.3.3-1; icecast (openSUSE:Tumbleweed) 2.4.2-1.7.
Low priority for now. Upgrade to icecast2 (Debian:12) 2.3.3-1; icecast (openSUSE:Tumbleweed) 2.4.2-1.7 or later.
