Noroxi assessment

Priority: Plan (action score 48/100)

  • 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: 30.2% (FIRST EPSS); higher than 98.2% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: acroread (Red Hat:rhel_extras:5::client) 0:9.5.1-1.el5; acroread-plugin (Red Hat:rhel_extras:5::client) 0:9.5.1-1.el5; acroread (Red Hat:rhel_extras:6) 0:9.5.1-1.el6_2.

Add it to your regular patch cycle. Upgrade to acroread (Red Hat:rhel_extras:5::client) 0:9.5.1-1.el5; acroread-plugin (Red Hat:rhel_extras:5::client) 0:9.5.1-1.el5; acroread (Red Hat:rhel_extras:6) 0:9.5.1-1.el6_2 or later.
