Palo Alto Networks Security Advisories / CVE-2020-2034

CVE-2020-2034 PAN-OS: OS command injection vulnerability in GlobalProtect

Severity 8.1 . HIGH
Attack Vector NETWORK
Attack Complexity HIGH
Privileges Required NONE
User Interaction NONE
Confidentiality Impact HIGH
Integrity Impact HIGH
Availability Impact HIGH
Published 2020-07-08
Updated 2020-07-10
Reference PAN-145587
Discovered internally


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

Product Status


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


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

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.


This issue was found by Yamata Li of Palo Alto Networks during internal
security review.
