What to do

Three steps, in this order

Step 1

Patch to the fixed version the vendor names, today if the product faces the internet.

Step 2

Until it is patched, take the affected service off the internet or put it behind a VPN or allow-list.

Step 3

Look for signs it was already used: new accounts, web shells, unexpected processes and outbound connections since the date it was listed.

CISA's required actionApply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes). Follow applicable BOD 26-04 guidance for cloud services or discontinue use of the product if mitigations are unavailable. Stakeholders are responsible for evaluating each asset's internet exposure and ensuring adherence to BOD 26-04 patching guidelines.
