Noroxi assessment

Priority: Plan (action score 40/100)

  • 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: 4.5% (FIRST EPSS); higher than 91.7% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: firefox-esr (Debian:12) 45.9.0esr-1; firefox-esr (Debian:7) 45.9.0esr-1~deb7u1; firefox-esr (Debian:8) 45.9.0esr-1~deb8u1.

Add it to your regular patch cycle. Upgrade to firefox-esr (Debian:12) 45.9.0esr-1; firefox-esr (Debian:7) 45.9.0esr-1~deb7u1; firefox-esr (Debian:8) 45.9.0esr-1~deb8u1 or later.
