Noroxi assessment

Priority: Plan (action score 42/100)

  • 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: 5.8% (FIRST EPSS); higher than 93.2% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: flash-plugin (Red Hat:rhel_extras:5::client) 0:10.3.183.11-1.el5; flash-plugin (Red Hat:rhel_extras:6) 0:10.3.183.11-1.el6.

Add it to your regular patch cycle. Upgrade to flash-plugin (Red Hat:rhel_extras:5::client) 0:10.3.183.11-1.el5; flash-plugin (Red Hat:rhel_extras:6) 0:10.3.183.11-1.el6 or later.
