Noroxi assessment

Priority: Now (action score 82/100)

  • CISA has confirmed exploitation in the wild (Mar 3, 2022). Remediation deadline for US federal agencies: Mar 24, 2022.
  • A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 70.3% (FIRST EPSS); higher than 99.3% of all records.
  • Someone with local access to the system can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: flash-plugin (Red Hat:rhel_extras:5::client) 0:11.2.202.238-1.el5; flash-plugin (Red Hat:rhel_extras:6) 0:11.2.202.238-1.el6.

Patch today or shut off access. Upgrade to flash-plugin (Red Hat:rhel_extras:5::client) 0:11.2.202.238-1.el5; flash-plugin (Red Hat:rhel_extras:6) 0:11.2.202.238-1.el6 or later.

Primary sources: NVD · CVE.org · CISA KEV · FIRST EPSS

Unspecified vulnerability in Adobe Flash Player before 11.3.300.271 on Windows and Mac OS X and before 11.2.202.238 on Linux allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via crafted SWF content, as exploited in the wild in August 2012 with SWF content in a Word document.
