Noroxi assessment

Priority: Plan (action score 53/100)

  • CISA has confirmed exploitation in the wild (Mar 11, 2025). Remediation deadline for US federal agencies: Apr 1, 2025.
  • Probability of exploitation in the next 30 days: 2% (FIRST EPSS); higher than 81.2% 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: Windows 10 for 32-bit Systems 10.0.10240.20947; Windows 10 for x64-based Systems 10.0.10240.20947; Windows 10 Version 1607 for 32-bit Systems 10.0.14393.7876.

Add it to your regular patch cycle. Upgrade to Windows 10 for 32-bit Systems 10.0.10240.20947; Windows 10 for x64-based Systems 10.0.10240.20947; Windows 10 Version 1607 for 32-bit Systems 10.0.14393.7876 or later.
