Recommended defensive actions

  • Review Microsoft’s security guidance for CVE-2024-38112 and apply the vendor-recommended mitigations.
  • Prioritize affected Windows endpoints and any systems that may expose or depend on MSHTML-related functionality.
  • If mitigations cannot be applied immediately, follow CISA’s guidance to discontinue use of the product or feature where feasible until protections are in place.
  • Verify remediation status before the CISA due date of 2024-07-30 and monitor for any vendor updates.
