Noroxi assessment

Priority: Plan (action score 59/100)

  • A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
  • Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 72.4% (FIRST EPSS); higher than 99.4% of all records.
  • Fixed version: flash-plugin (Red Hat:rhel_extras:5::client) 0:11.2.202.332-1.el5; flash-plugin (Red Hat:rhel_extras:6) 0:11.2.202.332-1.el6.

Add it to your regular patch cycle. Upgrade to flash-plugin (Red Hat:rhel_extras:5::client) 0:11.2.202.332-1.el5; flash-plugin (Red Hat:rhel_extras:6) 0:11.2.202.332-1.el6 or later.
