CVE-2021-3062

Estado: ModificadaAlta (8.8)—

An improper access control vulnerability in PAN-OS software enables an attacker with authenticated access to GlobalProtect portals and gateways to connect to the EC2 instance metadata endpoint for VM-Series firewalls hosted on Amazon AWS. Exploitation of this vulnerability enables an attacker to perform any operations allowed by the EC2 role in AWS. This issue impacts: PAN-OS 8.1 versions earlier than PAN-OS 8.1.20 VM-Series firewalls; PAN-OS 9.1 versions earlier than PAN-OS 9.1.11 VM-Series firewalls; PAN-OS 9.0 versions earlier than PAN-OS 9.0.14 VM-Series firewalls; PAN-OS 10.0 versions earlier than PAN-OS 10.0.8 VM-Series firewalls. Prisma Access customers are not impacted by this issue.
