2023-12-13 01:23
Details
An OS command injection vulnerability in the Simple Certificate Enrollment Protocol (SCEP) feature of PAN-OS software allows an unauthenticated network-based attacker with specific knowledge of the firewall configuration to execute arbitrary code with root user privileges. The attacker must have network access to the GlobalProtect interfaces to exploit this issue. This issue impacts: PAN-OS 8.1 versions earlier than PAN-OS 8.1.20-h1; PAN-OS 9.0 versions earlier than PAN-OS 9.0.14-h3; PAN-OS 9.1 versions earlier than PAN-OS 9.1.11-h2; PAN-OS 10.0 versions earlier than PAN-OS 10.0.8; PAN-OS 10.1 versions earlier than PAN-OS 10.1.3. Prisma Access customers with Prisma Access 2.1 Preferred and Prisma Access 2.1 Innovation firewalls are impacted by this issue.

Please note the special requirements for high-availability (HA) and Panorama-managed environments.\n\nAdditional information is available for Prisma Access customers at: https://docs.paloaltonetworks.com/prisma/prisma-access/innovation/2-1/prisma-access-panorama-admin/prepare-the-prisma-access-infrastructure/get-started-with-prisma-access-overview.html.\n\nRemove all configured SCEP profiles from the firewall to completely eliminate any risk of exploitation related to this issue. You can view any existing SCEP profiles configured on the firewall by selecting \u0027Device \u003e Certificate Management \u003e SCEP\u0027 from the web interface.\n\nThis issue requires the attacker to have network access to the GlobalProtect interface.\n\nIn addition to these workarounds, you should enable signatures for Unique Threat ID 91526 on traffic destined for GlobalProtect interfaces to further mitigate the risk of attacks against CVE-2021-3060. SSL decryption is not necessary to detect attacks against this issue."
