CVE-2024-49039

Microsoft Windows

Microsoft Windows Task Scheduler contains a privilege escalation vulnerability that can allow an attacker-provided, local application to escalate privileges outside of its AppContainer, and access privileged RPC functions.

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 2024-12-03. That deadline does not bind private companies, but it is a reasonable benchmark for how urgently CISA views it.

Required action

Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.

CISA’s wording, unedited.
