CVE-2019-0604

Microsoft SharePoint

Microsoft SharePoint fails to check the source markup of an application package. An attacker who successfully exploits the vulnerability could run remote code in the context of the SharePoint application pool and the SharePoint server farm account.

Exploitation status

  • CISA has confirmed this is being exploited in the wild. That is an observation of real attacks, not a prediction.
  • It is known to have been used in ransomware campaigns.
  • US federal civilian agencies are required to remediate it by 2022-05-03. 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.

CISA’s wording, unedited.
