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 memory corruption vulnerability in the processing of tunnel traffic in Palo Alto Networks PAN-OS® software allows an authenticated user to initiate system reboots using a maliciously crafted packet. Repeated attempts to initiate a reboot causes the firewall to enter maintenance mode. Panorama, Cloud NGFW, and Prisma® Access are not impacted by this vulnerability.

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

Memory corruption vulnerability in PAN-OS tunnel traffic processing allows authenticated users to trigger system reboots via maliciously crafted packets. Repeated exploitation forces the firewall into maintenance mode.

MitigationApply the vendor-supplied PAN-OS patch when available; until then, limit authenticated access to trusted personnel only.

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. Check PAN-OS version
    Run 'show system info' or 'show version' in the PAN-OS CLI, or view Device > Setup > Operations > Device Information in the web UI
    Affected if The installed version matches any of the affected ranges: 10.2.0 to <10.2.7, 10.2.8 to <10.2.10, 10.2.11 to <10.2.13, 10.2.14 to <10.2.16, =10.2.17, 11.1.0 to <11.1.4, 11.1.5 to <11.1.6, or 11.1.7 to <11.1.10
  2. Verify tunnel interfaces are configured
    Run 'show interface tunnel' or 'show tunnel info' in the CLI, or view Network > Tunnels in the web UI to list active tunnel interfaces
    Affected if Any tunnel interfaces (such as IPsec, SSL-VPN, or GRE tunnels) are configured and active on the firewall
  3. Confirm administrative access exists
    Run 'show admin users' in the CLI to view currently logged-in administrators, or review Device > Administrators to list all admin accounts
    Affected if Multiple administrative accounts exist or administrative access is not restricted to a limited set of trusted users, since authentication is required for exploitation
  4. Check for unexpected system reboots
    Review system logs via 'show system logs' or the web UI under Monitor > Logs > System for entries indicating unexpected reboots or entries containing 'maintenance mode'
    Affected if System logs show frequent unexpected reboots or entries indicating the device entered maintenance mode

A user is affected if their PAN-OS version falls within the vulnerable ranges AND tunnel interfaces are configured AND they have administrative accounts that could be compromised.

Fixed in 10.2.710.2.1010.2.13
Interim mitigation

Apply the vendor-supplied PAN-OS patch when available; until then, limit authenticated access to trusted personnel only.

Recommended fix High confidence

PAN-OS 10.2.16 or later (latest stable 10.2.x release)

  1. 1. Verify current PAN-OS version by navigating to Device > Support or using 'show system info' command
  2. 2. Review the current configuration and ensure a backup is available
  3. 3. Schedule a maintenance window as the upgrade will require a firewall reboot
  4. 4. Download the appropriate PAN-OS upgrade from the Palo Alto Networks Customer Support Portal
  5. 5. Upload the PAN-OS upgrade file via Dashboard > Software or via CLI: request system software upload <filename>
  6. 6. Install the upgrade: request system software install <filename>
  7. 7. After installation completes, reboot the firewall: request system restart
  8. 8. Verify the upgrade was successful and the firewall is operational
