Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
An OS command injection vulnerability in the Palo Alto Networks PAN-OS web interface enables an authenticated administrator to execute arbitrary OS commands to escalate privileges. This issue impacts: PAN-OS 9.0 version 9.0.10 through PAN-OS 9.0.14; PAN-OS 9.1 version 9.1.4 through PAN-OS 9.1.10; PAN-OS 10.0 version 10.0.7 and earlier PAN-OS 10.0 versions; PAN-OS 10.1 version 10.1.0 through PAN-OS 10.1.1. Prisma Access firewalls and firewalls running PAN-OS 8.1 versions are not impacted by this issue.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

OS command injection vulnerability in the PAN-OS web interface allows authenticated administrators to execute arbitrary OS commands with elevated privileges. The flaw exists in the web-based management interface and affects multiple PAN-OS version ranges (9.0.10-9.0.14, 9.1.4-9.1.10, 10.0.x through 10.0.7, and 10.1.0-10.1.1).

MitigationUpgrade PAN-OS to a fixed version beyond the affected ranges; PAN-OS 8.1 and Prisma Access are not impacted. Restrict web interface access to trusted admin networks as a compensating control.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify PAN-OS version
    Run 'show system info' from the CLI or check the Dashboard in the web interface to determine the installed PAN-OS version number
    Affected if The version falls within these ranges: 9.0.0-9.0.14, 9.1.0-9.1.10, 10.0.0-10.0.7, or 10.1.0-10.1.1 (specifically any version >= 9.0.0 and < 9.0.15, >= 9.1.0 and < 9.1.11, >= 10.0.0 and < 10.0.8, or >= 10.1.0 and < 10.1.2)

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

Upgrade available Upgrade to 9.0.15 / 9.1.11 / 10.0.8 or later
Fixed in 9.0.159.1.1110.0.8
Interim mitigation

Upgrade PAN-OS to a fixed version beyond the affected ranges; PAN-OS 8.1 and Prisma Access are not impacted. Restrict web interface access to trusted admin networks as a compensating control.

Recommended fix High confidence

PAN-OS 9.0.15 (or latest 9.0.x), PAN-OS 9.1.11 (or latest 9.1.x), PAN-OS 10.0.8 (or latest 10.0.x), or PAN-OS 10.1.2 (or latest 10.1.x)

  1. 1. Identify the current PAN-OS version by navigating to Dashboard > General Information in the web interface or running 'show system info' in the CLI
  2. 2. Determine which version branch (9.0.x, 9.1.x, 10.0.x, or 10.1.x) your current installation is on
  3. 3. Download the appropriate fixed PAN-OS release from the Palo Alto Networks Customer Support Portal: PAN-OS 9.0.15 or later, PAN-OS 9.1.11 or later, PAN-OS 10.0.8 or later, or PAN-OS 10.1.2 or later
  4. 4. Review the PAN-OS Upgrade Guide for your specific version at docs.paloaltonetworks.com
  5. 5. Create a backup of the current configuration using 'scp export configuration' or the web interface
  6. 6. Upload the new PAN-OS image via Device > Software > Upload in the web interface
  7. 7. Install the update via Device > Software > Install and select the new version
  8. 8. After reboot, verify the upgrade was successful and confirm the new version at Dashboard > General Information
