Noroxi assessment

Priority: Monitor (action score 27/100)

  • 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: 3.7% (FIRST EPSS); higher than 90% 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: flash-plugin (Red Hat:rhel_extras:6) 0:26.0.0.137-1.el6_9.

Low priority for now. Upgrade to flash-plugin (Red Hat:rhel_extras:6) 0:26.0.0.137-1.el6_9 or later.
