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
A packet processing mechanism in Palo Alto Networks PAN-OS software enables a remote attacker to reboot hardware-based firewalls. Repeated attacks eventually cause the firewall to enter maintenance mode, which requires manual intervention to bring the firewall back online. This affects the following hardware firewall models: - PA-5400 Series firewalls - PA-7000 Series firewalls

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 · moderate confidence

A vulnerability in the packet processing mechanism of PAN-OS software allows remote attackers to send specially crafted packets that cause hardware-based firewalls (PA-5400 and PA-7000 Series) to reboot. Repeated exploitation can trigger maintenance mode, requiring manual intervention for recovery.

MitigationApply the vendor-supplied PAN-OS update for this vulnerability. Implement network-level filtering or rate limiting to reduce attack surface until the patch can be deployed. Plan maintenance windows for affected hardware firewalls given the manual recovery requirement.

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 the hardware model
    Run 'show system info' or access the device dashboard to confirm the model is a PA-5400 or PA-7000 Series firewall
    Affected if The device is a PA-5400 or PA-7000 Series hardware appliance - only these models are affected
  2. Check the PAN-OS version
    Run 'show system info' or 'request system software info' to retrieve the installed PAN-OS version
    Affected if The installed version falls within: 9.0.0-9.0.16, 9.1.0-9.1.16, 10.1.0-10.1.11, 10.2.0-10.2.7, 11.0.0-11.0.2, or equals 9.0.17
  3. Verify network exposure of the firewall
    Review interface configurations and access policies to determine if the firewall can receive specially crafted packets from untrusted networks
    Affected if The firewall data plane or management interface is directly accessible from untrusted networks without adequate filtering or rate limiting

You are affected if you run a PA-5400 or PA-7000 Series firewall with PAN-OS version 9.0.0-9.0.16, 9.1.0-9.1.16, 10.1.0-10.1.11, 10.2.0-10.2.7, 11.0.0-11.0.2, or 9.0.17, and the device is network-accessible to potential attackers sending crafted packets.

Upgrade available Upgrade to 9.1.17 / 10.1.12 / 10.2.8 or later
Fixed in 9.1.1710.1.1210.2.8
Interim mitigation

Apply the vendor-supplied PAN-OS update for this vulnerability. Implement network-level filtering or rate limiting to reduce attack surface until the patch can be deployed. Plan maintenance windows for affected hardware firewalls given the manual recovery requirement.

Recommended fix Moderate confidence

PAN-OS 9.0.17+, 9.1.17+, 10.1.12+, or 10.2.8+ (migration to newer branches like 10.2 or 11.0 recommended)

  1. 1. Identify the current PAN-OS version running on the affected firewall (PA-5400 Series or PA-7000 Series) using the web interface or CLI command 'show system info'
  2. 2. Determine which version branch the current installation belongs to (9.0.x, 9.1.x, 10.1.x, or 10.2.x)
  3. 3. Download the appropriate PAN-OS upgrade image from the Palo Alto Networks Customer Support Portal
  4. 4. For PAN-OS 9.0.x: upgrade to PAN-OS 9.0.17 or later (note: 9.0 is End-of-Life, consider upgrading to a supported branch)
  5. 5. For PAN-OS 9.1.x: upgrade to PAN-OS 9.1.17 or later (note: 9.1 is End-of-Life, consider upgrading to a supported branch)
  6. 6. For PAN-OS 10.1.x: upgrade to PAN-OS 10.1.12 or later
  7. 7. For PAN-OS 10.2.x: upgrade to PAN-OS 10.2.8 or later
  8. 8. Upload the upgrade file via Panorama or directly to the firewall
Caveat Upgrading across major branches may require compatibility checks; 9.0 and 9.1 branches are End-of-Life - consider migrating to 10.2 or 11.0 for long-term support
