Noroxi assessment

Priority: This week (action score 62/100)

  • CISA has confirmed exploitation in the wild (Mar 28, 2022). Remediation deadline for US federal agencies: Apr 18, 2022.
  • Probability of exploitation in the next 30 days: 7.7% (FIRST EPSS); higher than 94.7% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. Special conditions such as timing or configuration are required.
  • Fixed version: flash-plugin (Red Hat:rhel_extras:5::client) 0:10.3.183.20-1.el5; flash-plugin (Red Hat:rhel_extras:6) 0:10.3.183.20-1.el6.

Don’t wait for the next maintenance window. Upgrade to flash-plugin (Red Hat:rhel_extras:5::client) 0:10.3.183.20-1.el5; flash-plugin (Red Hat:rhel_extras:6) 0:10.3.183.20-1.el6 or later.
