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 null pointer dereference vulnerability in the GlobalProtect gateway in Palo Alto Networks PAN-OS software enables an unauthenticated attacker to stop the GlobalProtect service on the firewall by sending a specially crafted packet that causes a denial of service (DoS) condition. Repeated attempts to trigger this condition result in the firewall entering maintenance mode.

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 null pointer dereference vulnerability in the GlobalProtect gateway in PAN-OS allows unauthenticated attackers to send specially crafted packets that crash the GlobalProtect service, causing denial of service. Repeated exploitation forces the firewall into maintenance mode.

MitigationApply the vendor-provided PAN-OS patch for CVE-2024-2550; until patched, consider restricting GlobalProtect gateway access to trusted sources or implementing additional network-level controls.

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 installed PAN-OS version
    Run 'show system info' or access the firewall web interface under Device > Setup > Operations to view the PAN-OS version number
    Affected if The installed version falls within 10.2.0-10.2.10, 11.0.0-11.0.5, or 11.1.0-11.1.4
  2. Confirm GlobalProtect gateway is enabled
    Navigate to Network > GlobalProtect > Gateways or run 'show global-protect gateway' in the CLI to list active gateways
    Affected if At least one GlobalProtect gateway is configured and enabled on the firewall
  3. Verify GlobalProtect service accessibility
    Check the interface and zone assignment for GlobalProtect gateways under Network > GlobalProtect > Gateways, and review external interface exposure using 'show interface' or the web interface
    Affected if The GlobalProtect gateway is reachable from untrusted or external networks (such as the internet or untrusted zones)

A system is affected if it runs a vulnerable PAN-OS version (10.2.0-10.2.10, 11.0.0-11.0.5, or 11.1.0-11.1.4) AND has a GlobalProtect gateway enabled and accessible to unauthenticated attackers.

Upgrade available Upgrade to 10.2.7 / 11.0.6 / 11.1.4 or later
Fixed in 10.2.711.0.611.1.4
Interim mitigation

Apply the vendor-provided PAN-OS patch for CVE-2024-2550; until patched, consider restricting GlobalProtect gateway access to trusted sources or implementing additional network-level controls.

Recommended fix High confidence

PAN-OS 10.2.7-h2 or later (10.2.x branch); PAN-OS 11.0.6-h2 or later (11.0.x branch); PAN-OS 11.1.4-h2 or later (11.1.x branch)

  1. 1. Identify the current PAN-OS version running on the firewall by navigating to Device > Dynamic Updates in the web interface or using 'show system info' in the CLI
  2. 2. Based on the current version branch, determine the minimum fixed release: for 10.2.x upgrade to 10.2.7-h2 or later; for 11.0.x upgrade to 11.0.6-h2 or later; for 11.1.x upgrade to 11.1.4-h2 or later
  3. 3. Download the recommended PAN-OS upgrade file from the Palo Alto Networks Customer Support Portal
  4. 4. Before upgrading, backup the firewall configuration via Device > Setup > Operations > Save Config Named Version
  5. 5. Upload the PAN-OS upgrade file via Device > Software > Upload
  6. 6. Install the upgrade: Device > Software > Install and select the uploaded version
  7. 7. After installation, reboot the firewall to load the new version
  8. 8. Verify the upgrade was successful and the GlobalProtect service is running normally
