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
Multiple denial of service vulnerabilities in Palo Alto Networks PAN-OS® software allow an unauthenticated attacker with network access to cause a denial of service (DoS) condition by sending specially crafted network traffic to or through a dataplane interface. Repeated attempts to trigger this condition result in the firewall entering maintenance mode. Panorama is not impacted by these vulnerabilities.

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

Palo Alto Networks PAN-OS contains multiple DoS vulnerabilities allowing unauthenticated attackers with network access to send specially crafted packets to dataplane interfaces, causing a denial of service condition. Repeated exploitation forces the firewall into maintenance mode, disrupting network protection. Panorama appliances are not affected by these vulnerabilities.

MitigationApply the relevant PAN-OS security update when available; restrict network access to dataplane interfaces to minimize attack surface until patching is feasible.

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. Confirm product is PAN-OS and not Panorama
    Access the firewall web interface and check System > About > Device > Model, or run 'show system info' in CLI. Panorama appliances are not affected by this vulnerability.
    Affected if The device is a Panorama appliance - these are explicitly not affected per the CVE description
  2. Identify installed PAN-OS version
    In the web interface go to Device > Setup > Operations > Device Information, or in CLI run 'show system info' and note the 'PAN-OS' or 'Software Version' field.
    Affected if The installed version falls within: 10.2.0 through 10.2.6, 10.2.7, 10.2.8 through 10.2.9, 10.2.10, 10.2.11 through 10.2.12, 10.2.13, 10.2.14 through 10.2.15, 10.2.16, 10.2.17, 10.2.18, 11.1.0 through 11.1.3, or 11.1.8 through 11.1.9 - OR if running Paloaltonetworks Cloud NGFW (all versions are affec
  3. Check network exposure of dataplane interfaces
    Review firewall network configuration to determine if dataplane interfaces (such as ethernet1/1 or aggregate interfaces) are reachable from untrusted networks. Examine interface zones and security policies controlling access to these interfaces.
    Affected if Dataplane interfaces have exposure to untrusted or external networks - the CVE requires network access to these interfaces for exploitation

You are affected if you are running PAN-OS (not Panorama) with a version matching the affected ranges above AND your dataplane interfaces are accessible from network paths an attacker could reach.

Upgrade available Upgrade to 10.2.7 / 10.2.10 / 10.2.13 or later
Fixed in 10.2.710.2.1010.2.13
Interim mitigation

Apply the relevant PAN-OS security update when available; restrict network access to dataplane interfaces to minimize attack surface until patching is feasible.

Recommended fix Moderate confidence

PAN-OS 10.2.16 or later (10.2 branch); Cloud NGFW - contact Palo Alto Networks for latest fixed release

  1. 1. Identify the current PAN-OS version installed on the firewall by navigating to Device > Summary in the web interface or running 'show system info' in the CLI.
  2. 2. Determine which version branch (10.2.x) is currently running and cross-reference with the affected version ranges provided (>= 10.2.0,<10.2.7; >=10.2.8,<10.2.10; >=10.2.11,<10.2.13; >=10.2.14,<10.2.16).
  3. 3. For PAN-OS 10.2.x: upgrade to the fixed release (10.2.16 or later for the 10.2 branch) by downloading the upgrade image from the Palo Alto Networks Customer Support Portal.
  4. 4. For Cloud NGFW: contact Palo Alto Networks support or documentation for the latest fixed release, as all versions are affected.
  5. 5. Before upgrading, review the PAN-OS Upgrade Guide and take a configuration backup (Device > Setup > Operations > Save config).
  6. 6. Schedule a maintenance window as the upgrade will require a firewall restart.
  7. 7. Upload and install the new PAN-OS version, then verify the firewall returns to a operational state after reboot.
Caveat Review PAN-OS 10.2.16 release notes for any configuration or feature changes before upgrading; may require compatibility checks with Panorama if used
