Description
Using the AES-128-CCM algorithm for IPSec on certain Palo Alto Networks PAN-OS® firewalls (PA-7500, PA-5400, PA-5400f, PA-3400, PA-1600, PA-1400, and PA-400 Series) leads to unencrypted data transfer to devices that are connected to the PAN-OS firewall through IPSec.

This issue does not affect Cloud NGFWs, Prisma® Access instances, or PAN-OS VM-Series firewalls.

NOTE: The AES-128-CCM encryption algorithm is not recommended for use.

Remediation

Vendor Workaround

Configure IPSec Crypto encryption to an algorithm that meets current security standards, such as AES-256-GCM or AES-256-CBC, on PA 7500, PA 5400, PA 5400f, PA 3400, PA 1600, PA 1400, and PA 400 series hardware PAN-OS firewalls. For more information on configuring the IPSec Crypto Profiles see our documentation https://docs.paloaltonetworks.com/network-security/ipsec-vpn/administration/set-up-site-to-site-vpn/define-cryptographic-profiles/define-ipsec-crypto-profiles .
