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.

What to do
Solution: Version Minor Version Suggested Solution PAN-OS 11.2 No action needed PAN-OS 11.111.1.0 through 11.1.4 Upgrade to 11.1.5 or laterPAN-OS 11.0 11.0.0 through 11.0.6 Upgrade to 11.0.7 or later PAN-OS 10.2 10.2.0 through 10.2.10Upgrade to 10.2.11 or laterPAN-OS 10.1 10.1.0 through 10.1.14 Upgrade to 10.1.14-h14 or later All other older unsupported PAN-OS versions Upgrade to a supported fixed version. PAN-OS 11.0 is EoL. We listed it in this section for completeness and because we added a patch for PAN-OS 11.0 before it reached EoL. If you are running PAN-OS 11.0 on any of your firewalls, though, we strongly recommend that you upgrade to a supported (non-EoL) fixed version.
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 .
