CVE-2025-0136Network attack vector

IPSec traffic exposure via AES-128-CCM

Published May 14, 2025 · Updated May 14, 2025

Cleartext transmission in Palo Alto Networks PAN-OS allows remote authenticated users to expose IPSec traffic through AES-128-CCM. On affected Intel-based firewalls, the IPSec crypto profile transfers payload data without encryption when AES-128-CCM is selected. Exposure requires an affected x86_64 PA hardware series with that algorithm configured; Cloud NGFW, Prisma Access, and VM-Series are unaffected.
