Recommendation: Monitor — no exploitation signal at the moment.

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.
