HIGH Attack Vector NETWORK Attack Complexity HIGH Privileges Required NONE User Interaction NONE Scope UNCHANGED Confidentiality Impact HIGH Integrity Impact HIGH Availability Impact HIGH NVD JSON Published 2020-07-08 Updated 2020-07-10 Reference PAN-145587 Discovered internally Description An OS Command Injection vulnerability in the PAN-OS GlobalProtect portal allows an unauthenticated network-based attacker to execute arbitrary OS commands with root privileges. An attacker would require some level of specific information about the configuration of an impacted firewall or perform brute-force attacks to exploit this issue. This issue cannot be exploited if the GlobalProtect portal feature is not enabled. This issue impacts PAN-OS 9.1 versions earlier than PAN-OS 9.1.3; PAN-OS 8.1 versions earlier than PAN-OS 8.1.15; PAN-OS 9.0 versions earlier than PAN-OS 9.0.9; all versions of PAN-OS 8.0 and PAN-OS 7.1. Prisma Access services are not impacted by this vulnerability. Firewalls that were upgraded to the latest versions of PAN-OS to resolve CVE-2020-2021 are not vulnerable to this issue. Palo Alto Networks is not aware of any malicious attempts to exploit this vulnerability. Product Status PAN-OS Versions Affected Unaffected 9.1 < 9.1.3 >= 9.1.3 9.0 < 9.0.9 >= 9.0.9 8.1 < 8.1.15 >= 8.1.15 8.0 8.0.* 7.1 7.1.* Required Configuration for Exposure This issue is applicable only where GlobalProtect portal is enabled. Severity: HIGH CVSSv3.1 Base Score: 8.1 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H) Weakness Type CWE-78 OS Command Injection Solution This issue is fixed in PAN-OS 8.1.15, PAN-OS 9.0.9, PAN-OS 9.1.3, and all later PAN-OS versions. PAN-OS 7.1 and PAN-OS 8.0 are end-of-life (as of June 30, 2020 and October 31, 2019 respectively) and are no longer covered by our Product Security Assurance policies. Workarounds and Mitigations Until PAN-OS software is upgraded to a fixed version, enabling signatures for Unique Threat ID 58658 on traffic destined for the GlobalProtect portal will block attacks against CVE-2020-2034.
