Microsoft Office

A remote code execution vulnerability exists in Microsoft Office software when the software fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user.

Exploitation status

  • CISA has confirmed this is being exploited in the wild. That is an observation of real attacks, not a prediction.
  • US federal civilian agencies are required to remediate it by 2022-03-24. That deadline does not bind private companies, but it is a reasonable benchmark for how urgently CISA views it.

Required action

Apply updates per vendor instructions.
