Exploitation status

  • It is known to have been used in ransomware campaigns.
  • US federal civilian agencies are required to remediate it by 2022-08-10. That deadline does not bind private companies, but it is a reasonable benchmark for how urgently CISA views it.
  • A vendor advisory or patch reference has been published.

Required action

Apply updates per vendor instructions.

CISA’s wording, unedited.
