Noroxi assessment
Priority: Monitor (action score 14/100)
- 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: 0.39% (FIRST EPSS).
- No special conditions are required; it is repeatable.
- Fixed version: xorg-server (Debian:12) 2:1.17.2-1.
Low priority for now. Upgrade to xorg-server (Debian:12) 2:1.17.2-1 or later.
