MediumCVSS 6.5 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 26/100)

  • 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: 1.4% (FIRST EPSS); higher than 74.3% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: aom (Debian:10) 1.0.0-3+deb10u1; aom (Debian:11) 1.0.0.errata1-3+deb11u1; aom (Debian:12) 3.2.0-1.

Low priority for now. Upgrade to aom (Debian:10) 1.0.0-3+deb10u1; aom (Debian:11) 1.0.0.errata1-3+deb11u1; aom (Debian:12) 3.2.0-1 or later.
