Noroxi assessment

Priority: This week (action score 76/100)

  • CISA has confirmed exploitation in the wild (Mar 3, 2022); it is known to be used in ransomware campaigns. Remediation deadline for US federal agencies: Mar 24, 2022.
  • Probability of exploitation in the next 30 days: 22.3% (FIRST EPSS); higher than 97.7% 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: flash-plugin (Red Hat:rhel_extras:5::client) 0:11.2.202.616-1.el5; flash-plugin (Red Hat:rhel_extras:6) 0:11.2.202.616-1.el6_7; flash-player (SUSE:Linux Enterprise Desktop 12) 11.2.202.616-126.1, 11.2.202.621-130.1.
  • Severity is disputed: the assigning authority (CNA) scores it 7.8, NVD 9.8.

Don’t wait for the next maintenance window. Upgrade to flash-plugin (Red Hat:rhel_extras:5::client) 0:11.2.202.616-1.el5; flash-plugin (Red Hat:rhel_extras:6) 0:11.2.202.616-1.el6_7; flash-player (SUSE:Linux Enterprise Desktop 12) 11.2.202.616-126.1, 11.2.202.621-130.1 or later.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Mar 3, 2022. That signals real attacks, not theory.

Remediation deadline for US federal agencies: Mar 24, 2022.

Known to be used in ransomware campaigns.
