CVE-2024-3388Network attack vector

Authenticated user impersonation via undisclosed gateway authorization flaw

Published Apr 10, 2024 · Updated Aug 1, 2024

Incorrect authorization in PAN-OS and Prisma Access allows remote authenticated users to send packets as another user through GlobalProtect. The flaw is in GlobalProtect Gateway handling of authenticated SSL VPN sessions, but Palo Alto Networks has not disclosed the faulty authorization operation. Exposure requires SSL VPN fallback or SSL-only tunneling; transmitted packets can reach internal assets, but responses cannot be received.
