Noroxi assessment
Priority: Monitor (action score 37/100)
- 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: 3.1% (FIRST EPSS); higher than 88% of all records.
- No special conditions are required; it is repeatable.
- Fixed version: asterisk (Debian:14) 1:1.8.3.3-1; asterisk (Debian:5.0) 1:1.4.21.2~dfsg-3+lenny2.1; asterisk (Debian:6.0) 1:1.6.2.9-2+squeeze2.
Low priority for now. Upgrade to asterisk (Debian:14) 1:1.8.3.3-1; asterisk (Debian:5.0) 1:1.4.21.2~dfsg-3+lenny2.1; asterisk (Debian:6.0) 1:1.6.2.9-2+squeeze2 or later.
