An OS command injection vulnerability in the Palo Alto Networks PAN-OS management interface exists when performing dynamic updates. This vulnerability enables a man-in-the-middle attacker to execute arbitrary OS commands to escalate privileges.
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 are not impacted by this issue.
|PAN-OS 10.1||< 10.1.3||>= 10.1.3|
|PAN-OS 10.0||< 10.0.8||>= 10.0.8|
|PAN-OS 9.1||< 9.1.11-h2||>= 9.1.11-h2|
|PAN-OS 9.0||< 9.0.14-h3||>= 9.0.14-h3|
|PAN-OS 8.1||< 8.1.20-h1||>= 8.1.20-h1|
|Prisma Access 2.2||None||all|
|Prisma Access 2.1||None||all|
This issue is applicable only to firewalls and Panoramas that receive dynamic updates from an update server.
To verify this on firewalls not managed by Panorama ‘Device > Dynamic Updates’ from the web interface.
To verify this on Panorama review ‘Panorama > Dynamic Updates’ from the web interface.
To verify this for Panorama managed firewalls review ‘Panorama > Device Deployment > Dynamic Updates’ from the Panorama web interface.
Firewalls that only receive content updates pushed from Panoramas are not susceptible to this issue.
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)
Palo Alto Networks is not aware of any malicious exploitation of this issue.
This issue is fixed in PAN-OS 8.1.20-h1, PAN-OS 9.0.14-h3, PAN-OS 9.1.11-h2, PAN-OS 10.0.8, PAN-OS 10.1.3, and all later PAN-OS versions.
Updating dynamic content from a local file will prevent exposure to this vulnerability until you are able to upgrade PAN-OS firewalls and Panorama to a fixed version. You can disable scheduled dynamic updates in the web interface.
Push content updates from Panorama to the managed firewalls until you are able to upgrade PAN-OS to a fixed version. The process of upgrading dynamic content on managed devices is referenced here:
