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: 0.53% (FIRST EPSS).
  • 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. Special conditions such as timing or configuration are required.
  • Fixed version: firefox (AlmaLinux:8) 91.12.0-2.el8_6.alma; thunderbird (AlmaLinux:8) 91.12.0-1.el8_6.alma; firefox (AlmaLinux:9) 91.12.0-2.el9_0.alma.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to firefox (AlmaLinux:8) 91.12.0-2.el8_6.alma; thunderbird (AlmaLinux:8) 91.12.0-1.el8_6.alma; firefox (AlmaLinux:9) 91.12.0-2.el9_0.alma or later.
