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 vulnerability in the GlobalProtect portal in Palo Alto Networks PAN-OS software enables a malicious authenticated GlobalProtect user to impersonate another GlobalProtect user. Active GlobalProtect users impersonated by an attacker who is exploiting this vulnerability are disconnected from GlobalProtect. Upon exploitation, PAN-OS logs indicate that the impersonated user authenticated to GlobalProtect, which hides the identity of the attacker.

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

A vulnerability in the GlobalProtect portal of Palo Alto Networks PAN-OS allows a malicious authenticated GlobalProtect user to impersonate another GlobalProtect user. The attack causes the impersonated user to be disconnected, and PAN-OS logs incorrectly show the impersonated user's authentication, effectively hiding the attacker's identity.

MitigationApply the relevant PAN-OS security update or patch for CVE-2024-8691 to GlobalProtect portal components. Review GlobalProtect authentication logs for anomalous session activity as a detective control until patching is complete.

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. Verify PAN-OS version
    Check the installed PAN-OS version on the device and compare it against the affected ranges: 9.1.0 through 9.1.16, and 10.1.0 through 10.1.10
    Affected if The installed version falls within >= 9.1.0 and < 9.1.17, or >= 10.1.0 and < 10.1.11
  2. Confirm GlobalProtect portal is configured
    Verify that the GlobalProtect portal feature is enabled and configured on the PAN-OS device
    Affected if GlobalProtect portal is active and accepting connections
  3. Review GlobalProtect authentication logs for session anomalies
    Inspect GlobalProtect authentication and session logs for signs of unexpected disconnections followed by authentication events that do not correspond to legitimate user activity
    Affected if Logs show users being disconnected and re-authenticated without legitimate user action, or sessions switching users unexpectedly

A user is affected if the PAN-OS version falls within the affected ranges AND GlobalProtect portal is enabled, as the vulnerability allows session impersonation of authenticated GlobalProtect users.

Interim mitigation

Apply the relevant PAN-OS security update or patch for CVE-2024-8691 to GlobalProtect portal components. Review GlobalProtect authentication logs for anomalous session activity as a detective control until patching is complete.

Recommended fix High confidence

PAN-OS 9.1.17 or later for 9.1.x branch; PAN-OS 10.1.11 or later for 10.1.x branch

  1. 1. Identify the current PAN-OS version by navigating to Dashboard > General Information in the web interface, or using 'show system info' in the CLI.
  2. 2. Confirm the installed version falls within the affected range: 9.1.0-9.1.16 or 10.1.0-10.1.10.
  3. 3. Review the Palo Alto Networks Upgrade Guide at docs.paloaltonetworks.com for pre-upgrade checks and compatibility requirements.
  4. 4. Download the appropriate PAN-OS upgrade image from the Palo Alto Networks Customer Support Portal based on your hardware model or VM series.
  5. 5. Schedule a maintenance window as the upgrade will require a system reboot.
  6. 6. Back up the current configuration via Device > Setup > Operations > Save Config, and export to a secure location.
  7. 7. Upload the new PAN-OS image via Device > Software > Upload, or via 'request system software upload' in the CLI.
  8. 8. Install the upgrade via Device > Software > Install, or via 'request system software install' in the CLI.
Caveat Review PAN-OS release notes for any feature changes or deprecations between your current version and the target version before upgrading
