Noroxi assessment

Priority: Monitor (action score 39/100)

  • 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: 5.3% (FIRST EPSS); higher than 92.7% of all records.
  • Fixed version: flash-plugin (Red Hat:rhel_extras:5::client) 0:10.3.183.18-1.el5; flash-plugin (Red Hat:rhel_extras:6) 0:10.3.183.18-1.el6.

Low priority for now. Upgrade to flash-plugin (Red Hat:rhel_extras:5::client) 0:10.3.183.18-1.el5; flash-plugin (Red Hat:rhel_extras:6) 0:10.3.183.18-1.el6 or later.
