Noroxi assessment

Priority: Now (action score 96/100)

  • CISA has confirmed exploitation in the wild (Jun 8, 2022). Remediation deadline for US federal agencies: Jun 22, 2022.
  • A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 88.5% (FIRST EPSS); higher than 99.7% 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:4) 0:9.4.7-1.el4; acroread-plugin (Red Hat:rhel_extras:4) 0:9.4.7-1.el4; acroread (Red Hat:rhel_extras:5::client) 0:9.4.7-1.el5.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Patch today or shut off access. Upgrade to acroread (Red Hat:rhel_extras:4) 0:9.4.7-1.el4; acroread-plugin (Red Hat:rhel_extras:4) 0:9.4.7-1.el4; acroread (Red Hat:rhel_extras:5::client) 0:9.4.7-1.el5 or later.
